A mysterious kidney disease that has killed over 20,000 people in Central America, most of them sugar cane workers, may be caused by chronic, severe dehydration linked to global climate change, according to a new study by Richard J. Johnson, MD, of the University of Colorado Anschutz Medical Campus.
In a previous life, Jo-Kristian Røttereng walked the rainforests of the Congo Basin, as a part of the Norwegian government’s NOK 3 billion effort to curb tropical deforestation. He’s seen the towering trees, heard the grunting of gorillas from deep in the jungle, watched brightly coloured birds flit through sunlight filtered through the thick forest canopy.
In the most authoritative forum yet held on the role of the polar regions in global climate change, the American Polar Society (APS), the 80-year-old organization linking scientists, explorers, and enthusiasts with deep interest in polar issues, and Scripps Institution of Oceanography at UC San Diego, are jointly bringing together world-class leaders in science and diplomacy in a symposium to review the latest findings from research on the impact of rising global temperatures on sea and land ice and their ecosystems at the top and bottom of the world.
The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to new study led by a University of Wyoming doctoral student.
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean and the more the region contributes to global sea-level rise. While this might seem obvious, it is no matter of course for the huge ice masses of Antarctica: parts of the ice continent are characterized by instabilities that, once triggered, can lead to persistent ice discharge into the ocean even without a further increase of warming - resulting in unstoppable long-term sea-level rise.
The targets for lower emissions of carbon dioxide from Europe's basic industries are out of reach, without urgent introduction of innovative carbon dioxide mitigation technologies.
The sensitivity of leaf unfolding phenology to climate warming has significantly declined since 1980s, according to a study recently published in the journal Nature by an international collaboration of scientists. Earlier spring leaf unfolding is a frequently observed response of plants to climate warming. Many deciduous tree species require cold temperatures, in other words ‘chilling’, for dormancy release, and the warming-related reductions in chilling may counteract the advance of leaf unfolding in response to warming. Empirical evidence for this, however, was very limited.
King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven't played a role in tens of millions of years, according to a new study led by Florida Institute of Technology.
Extreme summers like that of 2012 -- which saw record temperatures in cities across the U.S. -- may be atypical, but experts say they will return, especially as the planet warms under climate change. And as they do, cities will be especially vulnerable.
In a paper published today in Science, researchers from the University of Bristol describe how they used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide (CO2) levels during the Earth's last deglaciation.
