Species that live in symbiosis with others, which often occur in the most delicately balanced and threatened marine ecosystems such as coral reefs, are the slowest to recover their diversity if damag…
Deforestation of the Amazon is about to reach a threshold beyond which the region's tropical rainforest may undergo irreversible changes that transform the landscape into degraded savanna with sp…
Researchers show in a recent study that the further melting of glaciers cannot be prevented in the current century -- even if all emissions were stopped now. However, due to the slow reaction of glac…
Memories of the largest lava flood in the history of Iceland, recorded in an apocalyptic medieval poem, were used to drive the island's conversion to Christianity, new research suggests. Part of …
Methane (CH4) is a potent greenhouse gas, which is roughly 30 times more harmful to the climate than carbon dioxide (CO2). Both gases are produced in thawing permafrost as dead animal and plant remai…
History can tell us a lot about environmental upheaval, say Princeton University historians John Haldon and Lee Mordechai. What is missing in today's debate about climate change is using what we …
In the summer of 2010-2011 Western Australia experienced an unprecedented marine heat wave that elevated water temperatures 2-4°C above average for more than 2 months. The heat wave resulted in defol…
Earth is enduring a mass species extinction, scientists say -- the first since the demise of the dinosaurs and only the sixth in half-a-billion years. Orangutans in Borneo are just one of the world&#…
The eastern Mediterranean -- an area that covers Israel, Egypt, Jordan, Syria, Lebanon and southern Turkey -- is experiencing monumental climate changes poised to significantly affect regional ecosys…
The extreme wet and dry periods Mongolia has experienced in the late 20th and early 21st centuries are rare but not unprecedented and future droughts may be no worse, according to an international re…
Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, according to new research on Australia's Great Barrier Ree…
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability. Melting of Greenland ice sheet f…
A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide ad…
It may not rank among the all-time greatest dramas, but the history of ice on Greenland has been a source of scientific controversy for more than a decade. Iceberg off the coast of Greenland [Credit:…
