In a future shaped by climate change, only the strong – or heat-resistant – will survive. A study published this week in the Proceedings of the National Academy of Sciences opens a window into a genetic process that allows some corals to withstand unusually high temperatures and may hold a key to species survival for organisms around the world.
Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research from the University of Bristol.
As they typically result from severe external perturbations, it is of vital interest how stable the most desirable state is. Surprisingly, this basic question has so far received little attention. Now scientists of the Potsdam Institute for Climate Impact Research (PIK), in a paper published in Nature Physics, propose a new concept for quantifying stability.
What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It’s part of a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world’s soils and about twice as much as is in the atmosphere.
The new study, published today in the journal Nature, examined the probability of keeping average global temperatures from rising more than 2°C above preindustrial levels under varying levels of climate policy stringency, and thus mitigation costs. In addition, the study for the first time quantified and ranked the uncertainties associated with efforts to mitigate climate change, including questions about the climate itself, uncertainties related to future technologies and energy demand, and political uncertainties as to when action will be taken.
A recent study used bird watching records to build up the first bird watching database in China, which found a batch of new records of national level and a trend of of species moving to higher latitude and higher elevation regions.
In a discovery that raises further concerns about the future contribution of Antarctica to sea level rise, a new study finds that the western part of the ice sheet is experiencing nearly twice as much warming as previously thought.
If you think it’s been unusually hot lately, just wait—by the end of the century, temperatures in California are expected to rise significantly. What that means for human health, agriculture, water supply and a range of other spheres is being studied by experts, but what it will mean for our electricity system had not been examined until now, in an analysis by Lawrence Berkeley National Laboratory (Berkeley Lab) researchers.
Plant and animal species are shifting their geographic ranges and the timing of their life events – such as flowering, laying eggs or migrating – at faster rates than researchers documented just a few years ago, according to a technical report on biodiversity and ecosystems used as scientific input for the 2013 Third National Climate Assessment.
Intense but small-scale polar storms could make a big difference to climate predictions according to new research from the University of East Anglia and the University of Massachusetts.
