Higher sea levels and less silt will endanger many mangrove forests -- home to huge varieties of wildlife, and natural buffers that protect coasts and estuaries during tropical cyclones -- across the Pacific.
Sudden shifts in settled climates can occur long before global warming reaches the internationally agreed safety level, European scientists say.
We urgently need to view climate change not as a slow, linear process to which we can adapt safely over time, but as a nonlinear set of events involving dramatic and irreversible changes to the global ecosphere.
Coastal flooding will be immensely expensive for richer countries to tackle by 2100, scientists say -- and impossible for the poorest states, without action now.
Bigger species of wildlife appear to suffer more stress from climate change than their smaller counterparts, U.S. researchers have found.
There is no silver bullet for tackling climate change, U.S. scientists say. The only option is for every part of society to accept the need to adapt to it.
