Weekly Address: Progress with the G-20 in Pittsburgh

Posted by Jesse Lee
"Recorded literally on his way back from the G-20 Summit in Pittsburgh, the President uses his Weekly Address to recap the progress made during the intensive discussions with world leaders. From an historic agreement to reform the global financial system, to groundbreaking commitments on reducing subsidies to fossil fuels worldwide, to unity in standing against threats to world peace -- engagement produced tangible results in several areas."

President Obama also addressed the reduction of nuclear weapons: "The United States is meeting our responsibilities by pursuing an agreement with Russia to reduce our strategic warheads and launchers. And just as we meet our responsibilities, so must other nations, including Iran and North Korea.

"Earlier this year, we imposed tough, new, sanctions on North Korea to stop their efforts to develop weapons of mass destruction. And we will continue to stand with our allies and partners to press North Korea to move in a new direction.

"This week, we joined with the United Kingdom and France in presenting evidence that Iran has been building a secret nuclear facility to enrich uranium. This is a serious challenge to the global nonproliferation regime, and continues a disturbing pattern of Iranian evasion. That is why international negotiations with Iran scheduled for October 1st now take on added urgency.

"My offer of a serious, meaningful dialogue to resolve this issue remains open. But Iran must now cooperate fully with the International Atomic Energy Agency, and take action to demonstrate its peaceful intentions.

"On this, the international community is more united than ever before. Yesterday, I stood shoulder-to-shoulder with our European allies in condemning Iran’s program. In our meetings and public statements, President Medvedev of Russia and I agreed that Iran must pursue a new course or face consequences. All of the permanent members of the United Nations Security Council, and Germany, have made it clear that Iran must fulfill its responsibilities.

"Iran’s leaders must now choose – they can live up to their responsibilities and achieve integration with the community of nations. Or they will face increased pressure and isolation, and deny opportunity to their own people.

"These are the urgent threats of our time. And the United States is committed to a new chapter of international cooperation to meet them. This new chapter will not be written in one week or even one year. But we have begun. And for the American people and the people of the world, it will mean greater security and prosperity for years to come."



The Associated Press reported that: "The White House responded to the development by urging Iran's complete and immediate cooperation with the IAEA. ''After hiding this site from the international community for years, full transparency is essential, and it is time for Iran to play by the rules like everyone else,'' White House spokesman Tommy Vietor said.

Obama said in his address that evidence of Iran's building the underground plant ''continues a disturbing pattern of Iranian evasion'' that jeopardizes global nonproliferation.

"Ahead of Thursday's international talks with Iran in Geneva, Obama said the world ''is more united than ever before'' on this issue. Those negotiations, he said, ''now take on added urgency.''

Iran's failure to comply with international inspectors raised the potential of tougher economic penalties, although Obama and administration officials did not rule out military action.

''My offer of a serious, meaningful dialogue to resolve this issue remains open,'' Obama said, urging Tehran to ''take action to demonstrate its peaceful intentions.''

"Evidence of the clandestine facility was presented Friday by Obama and the leaders of Britain and France at the G-20 economic summit in Pittsburgh. The news overshadowed developments on regulating financial markets and reducing fossil fuel subsidies.

"Soon after, Russian President Dmitry Medvedev, at his own news conference, urged Iran to cooperate, as did Chinese Vice Foreign Minister He Yafei. He, however, did not endorse penalties against Tehran.

"At a news conference in New York, Iranian President Mahmoud Ahmadinejad said his country had done nothing wrong and Obama would regret his actions.

''What we did was completely legal, according to the law. We have informed the agency, the agency will come and take a look and produce a report and it's nothing new,'' he said.

"Ahmadinejad said the plant -- which Iranian officials say was reported to nuclear authorities as required -- wouldn't be operational for 18 months. But he sidestepped a question about whether Iran had sufficient uranium to manufacture a nuclear weapon."

Vice President Biden Increases His Involvement in Advocating Health Care Reform

Vice President Biden has increased active involvement with administration attempts to reform health care. This past Tuesday Mr. Biden met with state insurance commissioners to advocate tighter regulation of the health care must be implemented "to protect consumers and slow the spiraling cost of medical coverage."

Biden explained to the commissioners that the Obama plan will increase efficiency within the health care industry and in turn would have two immediate, positive effects; bringing about more competition and give consumers a wider range of choices, and in addition, would bring more consumers into the health care marketplace by tapping into the large number of Americans who do not currently have health insurance coverage.

Speaking to the overall positive effect of the Obama plan, Biden explained: "So, the profits might not be as high per person they cover, but there will be a much larger pool of paying customers."

Biden made his remarks advocating change in the current way that the health care industry operates based on the administration's contention that the nation faces an explosion in health care costs that threatens the ability of Americans to keep pace with escalating health care costs to the "National Association of Insurance Commissioners at National Harbor in Prince George's County," Maryland.

The next day, Biden spoke to senior citizens at a town hall meeting in Silver Spring, Maryland.



At the town hall meeting, Vice President Joe Biden joined with Health and Human Services (HHS) Secretary Kathleen Sebelius to tout the administration's issuance of a new document, "Health Insurance Reform and Medicare: Making Medicare Stronger for America's Seniors."

The Vice President tells seniors that the myths they've heard about health reform are "malarkey," as a new report shows how seniors and Medicare will benefit.

  
Biden was relaxed and at ease with the assembled crowd of seniors at Leisure World, a suburban Maryland retirement community, to reassure seniors about their Medicare coverage. He even took time to explain "about having to disabuse his own mother of myths being spread around about "death panels" and reduced Medicare benefits, getting laughs at the line: "I said, 'Mom, I'm trying to kill you," before explaining to her that it was a "bunch of malarkey."


Vice President Joe Biden speaks to seniors during a healthcare town hall meeting at Leisure World in Silver Springs, Maryland, Wednesday, September 23, 2009. Also in attendance were Secretary of Health and Human Services Kathleen Sebelius, and Director of the White House Office of Health Reform Nancy Ann De Parle.


“Nobody is going to mess with your benefits,” said Biden, who was joined by Health and Human Services Secretary Kathleen Sebelius and White House health adviser Nancy-Ann DeParle. “All we do is make it better for people on Medicare.”

The White House announced that: "The new report out of HHS addresses some of the common questions American seniors have about health insurance reform: How will reducing subsidies to Medicare Advantage plans affect me? How will health insurance reform make my care more affordable? Will health insurance reform actually improve my care? Will I have a choice of doctor? Will Medicare be there for me in the future?

"For each of these questions," the report details "the problems with the status quo and discusses the solutions provided by the President’s health insurance reform plan.  Some of the solutions listed in the report include:

    * Preserving and strengthening Medicare
    * Cutting high prescription drug costs
    * Making preventive services free
    * Ending overpayments to private insurance companies that cost all Medicare beneficiaries
    * Improving quality and patient safety
    * Making long term care services more affordable

President Barack Obama Makes His First Address to the United Nations General Assembly


In his first address to the UN General Assembly, the President denounces reflexive anti-Americanism and calls on the world's leaders to recognize the common challenges we face.


WEDNESDAY, SEPTEMBER 23RD, 2009 AT 1:23 PM
"Real Change is Possible"
Posted by Jesse Lee


"In this morning's speech to the United Nations General Assembly, President Obama covered a range of topics—all under the umbrella of his desire for leaders to recognize the "common future" of a world in which "the interests of peoples and nations are shared."




(President Barack Obama addresses the General Assembly of the UN in New York, Wednesday,

"He took the opportunity to reflect upon his first nine months in office, highlighting his administration's priorities and looking forward to challenges ahead:

"On my first day in office, I prohibited -- without exception or equivocation -- the use of torture by the United States of America.  (Applause.)  I ordered the prison at Guantanamo Bay closed, and we are doing the hard work of forging a framework to combat extremism within the rule of law.  Every nation must know: America will live its values, and we will lead by example.


"We have set a clear and focused goal:  to work with all members of this body to disrupt, dismantle, and defeat al Qaeda and its extremist allies -- a network that has killed thousands of people of many faiths and nations, and that plotted to blow up this very building.  In Afghanistan and Pakistan, we and many nations here are helping these governments develop the capacity to take the lead in this effort, while working to advance opportunity and security for their people.


"In Iraq, we are responsibly ending a war.  We have removed American combat brigades from Iraqi cities, and set a deadline of next August to remove all our combat brigades from Iraqi territory.  And I have made clear that we will help Iraqis transition to full responsibility for their future, and keep our commitment to remove all American troops by the end of 2011.


"I have outlined a comprehensive agenda to seek the goal of a world without nuclear weapons.  In Moscow, the United States and Russia announced that we would pursue substantial reductions in our strategic warheads and launchers.  At the Conference on Disarmament, we agreed on a work plan to negotiate an end to the production of fissile materials for nuclear weapons.  And this week, my Secretary of State will become the first senior American representative to the annual Members Conference of the Comprehensive Test Ban Treaty.


"Upon taking office, I appointed a Special Envoy for Middle East Peace, and America has worked steadily and aggressively to advance the cause of two states -- Israel and Palestine -- in which peace and security take root, and the rights of both Israelis and Palestinians are respected.


"To confront climate change, we have invested $80 billion in clean energy.  We have substantially increased our fuel-efficiency standards.  We have provided new incentives for conservation, launched an energy partnership across the Americas, and moved from a bystander to a leader in international climate negotiations.
To overcome an economic crisis that touches every corner of the world, we worked with the G20 nations to forge a coordinated international response of over $2 trillion in stimulus to bring the global economy back from the brink.  We mobilized resources that helped prevent the crisis from spreading further to developing countries.  And we joined with others to launch a $20 billion global food security initiative that will lend a hand to those who need it most, and help them build their own capacity.


"We've also re-engaged the United Nations.  We have paid our bills.  We have joined the Human Rights Council.  (Applause.)  We have signed the Convention of the Rights of Persons with Disabilities.  We have fully embraced the Millennium Development Goals.  And we address our priorities here, in this institution  -- for instance, through the Security Council meeting that I will chair tomorrow on nuclear non-proliferation and disarmament, and through the issues that I will discuss today.


"This is what we have already done.  But this is just a beginning.  Some of our actions have yielded progress.  Some have laid the groundwork for progress in the future.  But make no mistake:  This cannot solely be America's endeavor.  Those who used to chastise America for acting alone in the world cannot now stand by and wait for America to solve the world's problems alone.  We have sought -- in word and deed -- a new era of engagement with the world.  And now is the time for all of us to take our share of responsibility for a global response to global challenges.


"The President also outlined the "Four Pillars" he believes are "fundamental to the future that we want for our children": "non-proliferation and disarmament; the promotion of peace and security; the preservation of our planet; and a global economy that advances opportunity for all people."
 



(President Barack Obama addresses the General Assembly of the UN in New York, Wednesday,

"In closing, the President offered a fresh take on the crucial choice that faces the international body:

"In short, the United Nations can be an institution that is disconnected from what matters in the lives of our citizens, or it can be an indispensable factor in advancing the interests of the people we serve.


"We have reached a pivotal moment.  The United States stands ready to begin a new chapter of international cooperation -- one that recognizes the rights and responsibilities of all nations.  And so, with confidence in our cause, and with a commitment to our values, we call on all nations to join us in building the future that our people so richly deserve."

The White House on Health Care Reform: The "Obama Plan in Four Minutes"



The White House has unveiled a new video, culled from President  Obama's recent address before Congress that is claimed to explain the president's health care reform plan in four minutes:

"In an address to a joint session of Congress, President Obama explained how health insurance reform will provide more security and stability to those who have health insurance, coverage for those who don’t, and will lower the cost of health care for our families, our businesses, and our government."

"I suffer no illusions that this will be an easy process. It will be hard. But I also know that nearly a century after Teddy Roosevelt first called for reform, the cost of our health care has weighed down our economy and the conscience of our nation long enough. So let there be no doubt: health care reform cannot wait, it must not wait, and it will not wait another year."
– President Barack Obama, February 24, 2009

Progress

  • The President signed the Children’s Health Insurance Reauthorization Act on February 4, 2009, which provides quality health care to 11 million kids – 4 million who were previously uninsured.
  • The President’s American Recovery and Reinvestment Act protects health coverage for 7 million Americans who lose their jobs through a 65 percent COBRA subsidy to make coverage affordable.
  • The Recovery Act also invests $19 billion in computerized medical records that will help to reduce costs and improve quality while ensuring patients’ privacy.
  • The Recovery Act also provides:
    • $1 billion for prevention and wellness to improve America’s health and help to reduce health care costs;
    • $1.1 billion for research to give doctors tools to make the best treatment decisions for their patients by providing objective information on the relative benefits of treatments; and
    • $500 million for health workforce to help train the next generation of doctors and nurses.
     

Guiding Principles

"President Obama is committed to working with Congress to pass comprehensive health reform in his first year in order to control rising health care costs, guarantee choice of doctor, and assure high-quality, affordable health care for all Americans."
"Comprehensive health care reform can no longer wait. Rapidly escalating health care costs are crushing family, business, and government budgets. Employer-sponsored health insurance premiums have doubled in the last 9 years, a rate 3 times faster than cumulative wage increases. This forces families to sit around the kitchen table to make impossible choices between paying rent or paying health premiums. Given all that we spend on health care, American families should not be presented with that choice. The United States spent approximately $2.2 trillion on health care in 2007, or $7,421 per person – nearly twice the average of other developed nations. Americans spend more on health care than on housing or food. If rapid health cost growth persists, the Congressional Budget Office estimates that by 2025, one out of every four dollars in our national economy will be tied up in the health system. This growing burden will limit other investments and priorities that are needed to grow our economy. Rising health care costs also affect our economic competitiveness in the global economy, as American companies compete against companies in other countries that have dramatically lower health care costs.

"The President has vowed that the health reform process will be different in his Administration – an open, inclusive, and transparent process where all ideas are encouraged and all parties work together to find a solution to the health care crisis. Working together with members of Congress, doctors and hospitals, businesses and unions, and other key health care stakeholders, the President is committed to making sure we finally enact comprehensive health care reform.

"The Administration believes that comprehensive health reform should:
  • Reduce long-term growth of health care costs for businesses and government
  • Protect families from bankruptcy or debt because of health care costs
  • Guarantee choice of doctors and health plans
  • Invest in prevention and wellness
  • Improve patient safety and quality of care
  • Assure affordable, quality health coverage for all Americans
  • Maintain coverage when you change or lose your job
  • End barriers to coverage for people with pre-existing medical conditions

The Obama Plan: Stability & Security

for all Americans




"It will provide more security and stability to those who have health insurance. It will provide insurance to those who don’t. And it will lower the cost of health care for our families, our businesses, and our government."
– President Barack Obama

If You Have Health Insurance

More Stability and Security

  • Ends discrimination against people with pre-existing conditions. Over the last three years, 12 million people were denied coverage directly or indirectly through high premiums due to a pre-existing condition.  Under the President’s plan, it will be against the law for insurance companies to deny coverage for health reasons or risks. 
  • Limits premium discrimination based on gender and age. The President’s plan will end insurers’ practice of charging different premiums or denying coverage based on gender, and will limit premium variation based on age. 
  • Prevents insurance companies from dropping coverage when people are sick and need it most.  The President’s plan prohibits insurance companies from rescinding coverage that has already been purchased except in cases of fraud.  In most states, insurance companies can cancel a policy if any medical condition was not listed on the application – even one not related to a current illness or one the patient didn’t even know about. A recent Congressional investigation found that over five years, three large insurance companies cancelled coverage for 20,000 people, saving them from paying $300 million in medical claims - $300 million that became either an obligation for the patient’s family or bad debt for doctors and hospitals.
  • Caps out-of pocket expenses so people don’t go broke when they get sick.  The President’s plan will cap out-of-pocket expenses and will prohibit insurance companies from imposing annual or lifetime caps on benefit payments. A middle-class family purchasing health insurance directly from the individual insurance market today could spend up to 50 percent of household income on health care costs because there is no limit on out-of-pocket expenses.
  • Eliminates extra charges for preventive care like mammograms, flu shots and diabetes tests to improve health and save money. The President’s plan ensures that all Americans have access to free preventive services under their health insurance plans. Too many Americans forgo needed preventive care, in part because of the cost of check-ups and screenings that can identify health problems early when they can be most effectively treated. For example, 24 percent of women age 40 and over have not received a mammogram in the past two years, and 38 percent of adults age 50 and over have never had a colon cancer screening.
  • Protects Medicare for seniors. The President’s plan will extend new protections for Medicare beneficiaries that improve quality, coordinate care and reduce beneficiary and program costs.  These protections will extend the life of the Medicare Trust Fund to pay for care for future generations. 
  • Eliminates the "donut-hole" gap in coverage for prescription drugs.  The President’s plan begins immediately to close the Medicare "donut hole" - a current gap in its drug benefit - by providing a 50 percent discount on brand-name prescription drugs for seniors who fall into it.  In 2007, over 8 million seniors hit this coverage gap in the standard Medicare drug benefit.  By 2019, the President’s plan will completely close the "donut hole".  The average out-of-pocket spending for such beneficiaries who lack another source of insurance is $4,080.

If You Don't Have Insurance

Quality, Affordable Choices for All Americans

  • Creates a new insurance marketplace – the Exchange – that allows people without insurance and small businesses to compare plans and buy insurance at competitive prices.  The President’s plan allows Americans who have health insurance and like it to keep it.  But for those who lose their jobs, change jobs or move, new high quality, affordable options will be available in the exchange.  Beginning in 2013, the Exchange will give Americans without access to affordable insurance on the job, and small businesses one-stop shopping for insurance where they can easily compare options based on price, benefits, and quality. 
  • Provides new tax credits to help people buy insurance. The President’s plan will provide new tax credits on a sliding scale to individuals and families that will limit how much of their income can be spent on premiums.  There will also be greater protection for cost-sharing for out-of-pocket expenses.
  • Provides small businesses tax credits and affordable options for covering employees. The President’s plan will also provide small businesses with tax credits to offset costs of providing coverage for their workers.  Small businesses who for too long have faced higher prices than larger businesses, will now be eligible to enter the exchange so that they have lower costs and more choices for covering their workers.
  • Offers a public health insurance option to provide the uninsured and those who can’t find affordable coverage with a real choice.   The President believes this option will promote competition, hold insurance companies accountable and assure affordable choices. It is completely voluntary.  The President believes the public option must operate like any private insurance company – it must be self-sufficient and rely on the premiums it collects. 
  • Immediately offers new, low-cost coverage through a national "high risk" pool to protect people with preexisting conditions from financial ruin until the new Exchange is created.  For those Americans who cannot get insurance coverage today because of a pre-existing condition, the President’s plan will immediately make available coverage without a mark-up due to their health condition. This policy will offer protection against financial ruin until a wider array of choices become available in the new exchange in 2013.

For All Americans

Reins In the Cost of Health Care for Our Families, Our Businesses, and Our Government

  • Won’t add a dime to the deficit and is paid for upfront.  The President’s plan will not add one dime to the deficit today or in the future and is paid for in a fiscally responsible way.   It begins the process of reforming the health care system so that we can further curb health care cost growth over the long term, and invests in quality improvements, consumer protections, prevention, and premium assistance.  The plan fully pays for this investment through health system savings and new revenue including a fee on insurance companies that sell very expensive plans.
  • Requires additional cuts if savings are not realized. Under the plan, if the savings promised at the time of enactment don’t materialize, the President will be required to put forth additional savings to ensure that the plan does not add to the deficit.
  • Implements a number of delivery system reforms that begin to rein in health care costs and align incentives for hospitals, physicians, and others to improve quality.  The President’s plan includes proposals that will improve the way care is delivered to emphasize quality over quantity, including:  incentives for hospitals to prevent avoidable readmissions, pilots for new "bundled" payments in Medicare, and support for new models of delivering care through medical homes and accountable care organizations that focus on a coordinated approach to care and outcomes.
  • Creates an independent commission of doctors and medical experts to identify waste, fraud and abuse in the health care system.   The President’s plan will create an independent Commission, made up of doctors and medical experts, to make recommendations to Congress each year on how to promote greater efficiency and higher quality in Medicare.  The Commission will not be authorized to propose or implement Medicare changes that ration care or affect benefits, eligibility or beneficiary access to care.  It will ensure that your tax dollars go directly to caring for seniors.
  • Orders immediate medical malpractice reform projects that could help doctors focus on putting their patients first, not on practicing defensive medicine.  The President’s plan instructs the Secretary of Health and Human Services to move forward on awarding medical malpractice demonstration grants to states funded by the Agency for Healthcare Research and Quality as soon as possible.
  • Requires large employers to cover their employees and individuals who can afford it to buy insurance so everyone shares in the responsibility of reform.   Under the President’s plan, large businesses – those with more than 50 workers – will be required to offer their workers coverage or pay a fee to help cover the cost of making coverage affordable in the exchange. This will ensure that workers in firms not offering coverage will have affordable coverage options for themselves and their families.  Individuals who can afford it will have a responsibility to purchase coverage – but there will be a "hardship exemption" for those who cannot.

Extraordinary Images of Glaciers Photographed by Astronauts and Satellites Impressively Detail the Effects of Global Warming

From time to time, WIRED SCIENCE provides its readers with an impressive array of photos that visually present a compelling scientific issue. In the case concerning glaciers, they have a very important role in carving out and shaping the surface landscape features of the Earth. Because they are thousands of years old, glaciers provide scientists with access to the actual conditions of Earth's ancient atmospheres. Contemporary issues of global warming are witnessed by scientists who monitor the melting of glacial formations. Such is the case with the presentation on glaciers that follows:




Bear Glacier, Alaska

"This image taken in 2005 of Bear Glacier highlights the beautiful color of many glacial lakes. The hue is caused by the silt that is finely ground away from the valley walls by the glacier and deposited in the lake. The particles in this “glacial flour” can be very reflective, turning the water into a distinctive greenish blue. The lake, eight miles up from the terminus of the glacier, was held in place by the glacier, but in 2008 it broke through and drained into Resurrection Bay in Kenai Fjords National Park.

"The grey stripe down the middle of the glacier is called a medial moraine. It is formed when two glaciers flow into each other and join on their way downhill. When glaciers come together, their lateral moraines, long ridges formed along their edges as the freeze-thaw cycle of the glacier breaks off chunks of rock from the surrounding walls, meet to form a rocky ridge along the center of the joined glaciers."

Image: GeoEye/NASA, 2005





Heiltskuk Ice Field, British Columbia

"Covering nearly 1,400 square miles, the vast Heiltskuk Ice Field lies in the southern Coast Mountains of British Columbia. Taken by an astronaut on the International Space Station, this photo captures the snow-covered mountain slopes as well as several of the ice field’s valley glaciers, which are wide swaths of slowly flowing ice and debris. As these glaciers creep downhill, they carve out large U-shaped valleys that will remain long after the glacier melts. In fact, scientists use these characteristic valleys to identify regions that were once covered in ice but are now glacier-free.

"The two largest valley glaciers shown here are the Silverthrone Glacier and the Klinaklini Glacier, which merge with each other at the top of the photo. The dark lines of rock and detritus of the lateral and medial moraines along the edges and middle of the glaciers are clearly visible."

Image: NASA, 2009.



 
 
Erebus Ice Tongue, Antarctica

"The saw-shaped projection jutting out from this glacier is known as the Erebus Ice Tongue, a long, narrow sheet of ice almost 7 miles long and 33 feet high. This peculiar structure is formed as the Erebus glacier in Antarctica flows rapidly down Mount Erebus and into the McMurdo Sound. During the summer, when the rest of the sea ice in McMurdo melts, the ice tongue floats on the water without thawing. As waves of sea water crash over the sides of the tongue, they carve elaborate shapes and sometimes create deep caves along the edges of the ice sheet. Occasionally, sections of the ice tongue calve off to form small icebergs.

"Data for this false-color landscape was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, and the image was created by combining data in various wavelengths."

Image: NASA/ASTER, 2001




Western Greenland Valley

"This natural-color image captured in August shows several small glaciers spilling into a mostly dry valley in western Greenland that itself was formed by a glacier in the past. Ground up rock from past glaciations has collected in the valley, giving the pools of water at the snouts of the current glaciers a turquoise color.

"The photo was aqcuired by the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite."

Grey Glacier, Chile

"Part of the Southern Patagonian Ice Field of Chile and Argentina, Grey Glacier covered 104 square miles when it was measured in 1996. By 2007, when this photograph was taken by astronauts from the International Space Station, the glacier had shrunk considerably, as seen in a comparative false-color image. Scientists think increased regional temperatures and changes in the amount of precipitation have led to more ice calving off as free-floating chunks, and less ice being replenished each year.

"In the natural-color image above, Grey Glacier looks pale blue because ice absorbs red wavelengths of light and scatters blue. The rough surface of this part of the glacier is caused by vertical cracks in the surface called crevasses, which are formed near the ends of glaciers as the flow of ice at the bottom speeds up relative to the brittle ice on top."

Image: NASA, 2007.





Eugenie Glacier, Dobbin Bay in the Canadian Arctic

"This stunning shot of the Eugenie Glacier in the Canadian Arctic was taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite, which takes high-resolution images designed to detect even minute changes in the extent and features of the world’s glaciers.

"This image highlights the fact that glaciers are flowing much like water but at a far slower pace. Smaller glaciers flow down valleys like river tributaries into larger glaciers. The bottom of Eugenie Glacier is floating on the surface of Dobbin Bay; a close-up of the tongue shows extensive surface cracks and calving of small icebergs into the bay."

Image: NASA/ASTER, 2000





Retreat of the Helheim Glacier, Greenland

"Glaciers stay intact as long as the ice thickness and water depth allow them to stay firmly attached to the ground. But when the ice becomes too thin or the water gets too deep, the tip of a glacier starts to float and rapidly cracks into icebergs, creating what’s called a “calving edge.” This photograph, captured by NASA’s Terra satellite in 2003, shows the calving edge of the Helheim Glacier in Greenland. Comparing similar images from 2001 and 2005 reveals that the solid portion of the glacier has been shrinking rapidly. Measurements from NASA reveal that in just four years, the glacier’s margin retreated 4.7 miles and its flow speed increased from 5 to 7.5 miles per year. Between 2001 and 2003, the thickness of the glacier also shrunk by about 131 feet.

"Unfortunately, the entire Greenland Ice Sheet has been undergoing similar shrinkage, thinning by tens of yards in the past decade. While warmer temperatures have certainly caused some of the thinning, scientists also think that the retreat of the ice margin has played a role: With less grounded ice to slow the ice sheet down, it’s moving out to sea at a faster rate."

Image: NASA ASTER, 2003.





Ellesmere Island National Park Reserve

"This false-color composite image shows a tidewater glacier in the Greely Fjord that extends out over the sea water for a short distance and breaks off into icebergs, which can be seen floating away. The dark spots on the glaciers are likely melt ponds. The pond water is darker than the surface of the glacier and consequently absorbs more heat, which melts more ice and causes the ponds to grow. Sometimes, water from glacial melt ponds will flow through cracks in the glacier to the base, lubricating the surface and causing the glacier to flow more quickly."

Image: NASA/ASTER, 2003.



Mt. Rainier, Washington

"At 14,411 feet, Mt. Rainier is the tallest volcano in the Cascade Range and has a 1,280 foot-wide summit crater. On its eastern slope, it hosts Emmons Glacier, the largest glacier in the lower 48 states. Rainier is an active volcano that is continuously monitored by the U.S. Geological Survey’s Cascade Volcano Observatory. And though it last erupted in 1840, it is considered the most hazardous volcano in the country, in part because of the risk of flooding from melting glaciers in the event of an eruption. This photo was captured on a rare clear day by astronauts on the International Space Station."

Image: NASA, 2005




Upsala Glacier, Patagonian Argentina

"Upsala Glacier is the third largest glacier of the Southern Patagonian Ice Field at around 300 square miles and ends in Lake Argentino. Patagonian glaciers have been retreating rapidly in recent decades, some as much as 2.5 miles between the late 1960s and mid 1990s, making them a target for International Space Station crew observations. Upsala appears to still be retreating with visible changes between this photo taken in 2004 and another from 2000."

Byrd Glacier, Antarctica

"The Byrd Glacier near McMurdo Station in Antarctica runs 100 miles through a steep 15-mile-wide valley in the Transatlantic Mountains. This fast-flowing glacier moves ice toward the Ross Ice Shelf at the rate of one half mile a year and adds more ice to the ice sheet than any other glacier. Images such as this one from the U.S. Geological Survey’s Landsat-7 satellite have been combined to form the Landsat Image Mosaic of Antarctica. The mosaic incorporates more than 1,000 images."

Pasterze Glacier, Austria

European glaciers have been rapidly retreating in recent years, due to higher summer temperatures and lower winter precipitation. Pasterze Glacier has been shrinking since 1856. Satellite data such as this image is used by scientists to keep track of the movement of glaciers around the world.

Bering Glacier, Alaska

Bering Glacier, combined with the ice field that feeds it, is the largest glacier in North America at 2,000 square miles, as well as the longest at 118 miles. This glacier has retreated around 7.5 miles and thinned by several hundred yards over the last century, though it is still around 2,500 feet thick in some places. Scientists think the shrinking of Alaskan glaciers such as Bering has reduced the pressure on the boundary between tectonic plates beneath them and consequently increased the number of earthquakes in the region.
