Rivers in some of the world's most populous regions are losing water, according to a new comprehensive study of global stream flow. The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate change.

The existing infrastructure for responding to maritime accidents in the Arctic is limited and more needs to be done to enhance emergency response capacity as Arctic sea ice declines and ship traffic in the region increases, according to new report released today by the University of New Hampshire and the National Oceanic and Atmospheric Administration.

A new study reports that charcoal particles left by wildfires in sediments of 35 North American lake beds don't readily support the theory that comets exploding over the continent 12,900 years ago sparked a cooling period known as the Younger Dryas.

Some of these responses, including insect outbreaks, wildfire, and forest dieback, may adversely affect people as well as ecosystems and their plants and animals.

The United States could suffer the effects of abrupt climate changes within decades—sooner than some previously thought--says a new government report.

Reconstructing the climate of the past is an important tool for scientists to better understand and predict future climate changes that are the result of the present-day global warming. Although there is still little known about the Earth’s tropical and subtropical regions, these regions are thought to play an important role in both the evolution of prehistoric man and global climate changes.

Carnegie Mellon University's Christopher L. Weber argues that China's new title as the world's largest greenhouse gas emitter is at least partly due to consumption of Chinese goods in the West.

The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America.

Philanthropists Jeremy and Hannelore Grantham are creating a second climate change research centre in London, following their donation of £12 million to Imperial College in 2007 to establish the Grantham Institute for Climate Change, it was announced today.

If you missed last month’s Leverhulme Climate Symposium, you can now watch the highlights from the four day event online.

California electricity and natural gas customers will be charged $600 million over the next 10 years to fund a green think tank, the California Public Utilities Commission unanimously voted on Thursday.

Environmental groups have welcomed Prime Minister Kevin Rudd's announcement of closer cooperation with China on climate change issues.
