Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white. Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decades by snow and...

Trump is assembling an all-star cast of climate change deniers for his transition team – often placing them at the heads of key agencies responsible for monitoring or dealing with global warming. The heads of transition teams for Nasa, the Environmental Protection Agency, the Department of the Inter...

This story has been updated. Political people in the United States are watching the chaos in Washington in the moment. But some people in the science community are watching the chaos somewhere else — the Arctic. It’s polar night there now — the sun isn’t rising in much of the Arctic. Tha...

Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by ...

Flying over the North pole on my way back to the states from France made this whole global warming thing hard to understand. As I flew over Greenland, I saw that there was plenty of ice to share: with so much ice, how can there be a crisis? It did not make sense. Well after doing some digging on ho...

Greenland’s ice sheet shrank by an average of 243 billion tonnes a year between 2003 and 2009 – a rate of melting that is enough to raise the world’s sea levels by 0.68 mm per year. In what is claimed as the first detailed study, geologist Beata Csatho, of the University of Buffalo in the US, and c...

A large tabular iceberg (42 kilometers x 17 kilometers) broke off Pine Island Glacier, West Antarctica (75ºS latitude, 102ºW longitude) sometime between November 4 and 12, 2001. Images of the glacier were acquired by the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra spa...

The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new ...

An international team of scientists has discovered that the last remaining stable portion of the Greenland ice sheet is stable no more. The new result focuses on ice loss due to a major retreat of an outlet glacier connected to a long "river" of ice -- known as an ice stream -- that drains ice from...

A United Nations report raised the threat of climate change to a whole new level on Monday, warning of sweeping consequences to life and livelihood. The report from the UN's intergovernmental panel on climate change concluded that climate change was already having effects in real time – melting sea...

While 99 percent of Earth’s land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world’s glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado...

This year has predictably and deservedly received a fair amonut of media attention.  Jonathan Leake of the Sunday Times recently penned an article on the impending sea ice record.  The bulk of the article was quite good, but at the end succumbed to the standard mainstream media practice of...

Sea ice extent in the Arctic is very near to beating the previous record low set in 2007, according to the U.S. National Snow and Ice Data Center. Researchers told Reuters that they expect the record to be beaten by the end of month, well over a week before the melt season ends in the frozen north. ...

In Greenland Ice is melting fast. New Studies find temperatures rising. Like snow sliding off a roof on a sunny day, the Greenland Ice Sheet may be sliding faster into the ocean due to massive releases of meltwater from surface lakes, according to a new study by the University of Colorado Boulder-b...

As many of this column’s readers know, I am from the U.S. and have lived in Europe and most recently Canada for the 10 years since getting my Ph.D. at the University of Colorado.  While I am no economist (my Ph.D. is in business), I believe that the recent U.S. debt crisis and the complete and ...

A new study aimed at refining the way scientists measure ice loss in Greenland is providing a "high-definition picture" of climate-caused changes on the island. And the picture isn't pretty. In the last decade, two of the largest three glaciers draining that frozen landscape have lost enough ice tha...

Snow melt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study by NASA/UCLA shows this is due to increased dust caused by human activities in the typically arid American southwest region during the past 150 years.  ...
