For those who doubt global warming, it is difficult when someone points out something so blatantly obvious, it cannot be denied. Thus is the snowcap on Mt. Kilimanjaro in Africa an obvious indicator of the truth behind global climate change.

The Maldives is an water-bound island nation, and like many, has fears over the possible impact of climate change and global warming on its existence. Saturday, the President and cabinet took to the ocean, or rather, beneath the ocean, to highlight those concerns.

Apple has become the latest company, and probably the highest profile, to leave the U.S. Chamber of Commerce over that organization's stance against limiting greenhouse gases to slow the effects of global climate change. Three other companies, Pacific Gas and Electric, PNM Resources and Exelon, also recently pulled out of the Chamber over its climate policy. Additionally, Nike resigned its position on the Chamber’s board, though it has maintained its membership.

On "Real Time" Friday night Bill Maher raked climate change skeptics over the coals, particularly those in the GOP, insisting that they must "stop pretending climate change is a future problem." He showed images of Australia with its current host of wildfires, and wondered how those in Southern California would react to such a vista (see above).

An international study involving Monash University mathematician Dr Malcolm Clark has been used to demonstrate the impact of global warming and to predict the effect further warming will have on plant life.

A leaked memo obtained by Greenpeace reveals the American Petroleum Institute (API) is asking oil companies to recruit employees, retirees and contractors to take part in rallies against climate change legislation.

When scientists take Earth's temperature, they usually use thermometers. But when scientists want to figure out Earth's temperature in the past, they have to rely on other tools. One of these is deep-sea sediment cores (see Figure). Deep-sea sediments contain fossil remains of tiny marine creatures and other materials that sink to the ocean floor.

No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect.

Global warming is an observable fact. Glaciers are melting and temperatures are rising. No one denies this any longer. A few stubborn folks refuse to recognize that Global warming is the result of human carbon emissions. There is, however, such widespread scientific consensus and such ample evidence that we can safely ignore the fringe of "global warming skeptics." With this in mind, it is good news that the House has passed its first major climate bill.

Two new reports examining climate change adaptation and policy making across Europe will be launched today in Brussels in the presence of Peter Gammeltoft, Head of Unit 'Protection of Water & Marine Environment' at the European Commission. The preliminary conclusions of the research were used in the European Commission's White Paper on climate change, published in April 2009.

In a paper in Nature Geoscience, a team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from Tübingen (Germany) and Bristol presents a novel continuous reconstruction of sea level fluctuations over the last 520 thousand years.
