Study quantifies sea level rise from melting glaciers.
The world’s biggest ice sheets haven’t really started a major meltdown yet. But the rest of the world’s glacial regions have been losing ice at a rate of about 260 billion metric tons annually, raising sea level by about 0.03 inches per year — about a third of the observed sea level rise.
CU-Boulder researchers help show impact of global melt.
A new study that included contributions by University of Colorado researchers shows that glacial melt from sources not including the Greenland and Antarctic ice sheets contributes as much to sea level rise as does the ice loss from those two land masses.
EU Ice2sea report offers new estimates of sea level rise.
After four years of studies and more than 150 peer-reviewed papers, the EU-funded ice2sea program has concluded that under a moderate scenario, melting ice may contribute only 3.5 and 36.8 centimeters (1.4 to 14.5 inches) to sea level rise by 2100.
Mt. Everest’s glaciers melting away.
Even at the frozen roof of the world in the mighty Himalaya, global warming is evident. The snow line in the Mt. Everest region has moved uphill by 180 meters. Glaciers in the region are shrinking, and precipitation has declined, according to a team of scientists.
Cutthroat trout face upstream swim against climate change.
Colorado’s cutthroat trout live life on the edges, at high elevations and in isolated pockets other trout haven’t been able to reach. It appears to have toughened them up, according to a recent study looking at climate change’s impact on the species.
The subnivium, a secret world beneath the snow, is at risk from global warming.
Beneath winter’s deep snows there is a secret world of frozen insects and amphibians in quasi-hibernation. Now, the subnivium, as scientists have dubbed it, is at risk from global warming.
More hurricanes in Hawaii?
A poleward shift of the subtropical jet stream and warmer temperatures over the equatorial central Pacific will combine to make the powerful storms two to three times as likely by the last quarter of the century, according to scientists with the International Pacific Research Center, University of Hawaii at Manoa.
Global warming drives more climate disruption.
Climate-sensitive economic sectors like agriculture and energy are already feeling the pinch of more extreme fluctuations in the weather, driven by global climate change, according to the World Meteorological Organization, which released its annual climate statement for 2012 last week.
Global warming threatens Atlantic cod stocks.
With Atlantic cod already moving into waters around Spitsbergen — into Arctic cod territory — fisheries biologists are keeping a close eye the commercially important species to determine the consequences of climate-related migrations.
Report eyes Pacific Northwest climate change threats.
Managers of the Olympic Coast National Marine Sanctuary say they’ll use a new report to try and prepare the resources they steward for the coming impacts of climate change, including increases in sea level and extreme weather events such as winds, waves, and storms.
