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.
International climate agreements like the Kyoto Protocol may discourage much-needed investment in renewable energy sources, and hence be counterprodutive, according to new research.
From melting glaciers to increasing wildfires, the consequences of climate change and strategies to mitigate such consequences are often a hotly debated topic. A new study led by the University of Utah adds to the ever-growing list of negative impacts climate change can have on humans--low birth weight.
Researchers from the University of Exeter believe they have solved one of the biggest puzzles in climate science. The new study, published in Nature Geoscience, explains the synchrony observed during glacial periods when low temperatures in the Southern Ocean correspond with low levels of atmospheric carbon dioxide (CO2).
Fluctuations in extreme weather events, such as heavy rains and droughts, are affecting ecosystems in unexpected ways -- creating "winners and losers" among plant species that humans depend upon for food.
A landmark study published in Nature Climate Change today by Australian and British scientists predicts that climate change will have a major impact on life in Antarctica this century.
In a study published today in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere.
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.
Ozone, methane and aerosols (tiny pollutant particles) remain in the atmosphere for a shorter time than CO2, but can affect both the climate and air quality. Yet environmental policies tend to separate the two issues, with measures that fight air pollution not always bringing climate benefits and vice-versa.
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.
