CO2 release may be too fast for environment to cope say geologists

CO2 release may be too fast for environment to cope say geologists

Posted Mon, 06 Jun 2011 15:22:01 GMT by Colin Ricketts

An historical period of high CO2 concentration produced the greenhouse gas at only one tenth of current release rates and the speed of change may be too much for environments to adapt to say geologists.

One in 12 humans live in megacities and the leaders of more than 70 of the world's largest settlements have met in Sao Paolo to discuss how they can reduce their impact on the climate.

Biodegradable products may be a double-edged sword environmentally according to new research which shows the speed at which these products decay could be releasing the greenhouse gas methane in to the atmosphere.

Energy production continues to pump more CO2 into the atmosphere and the targets agreed by world leaders to limit warming to 2 degrees are now seriously threatened warns the International Energy Agency.

Rising temperatures will affect forests carbon storage role says study

As temperatures rise forest soils will store less carbon says a new study but, according to Jerry Melillo, trees may see carbon-storing growth spurts too. However, the increased temperature also speeded up the nitrogen cycle, enabling trees to store more carbon, partially offsetting the CO2 released from decaying matter in the soil.

South Georgia's unrivaled biodiversity challenged by warming

The chilly south Atlantic islands of South Georgia can boast a higher level of biodiversity than some tropical islands, says a new study from the British Antarctic Survey. Published in this week's PloS ONE. Over 1,500 marine species have been collected near the islands over the lat century, but the fastest sea warming in the Southern hemisphere may threaten this biodiversity hot-spot.

A new deal aims to involve the indigenous peoples of the Amazon in efforts to protect this vital environment which is one of the front lines in the battle against climate change. The partnership between the Coordinator of Indigenous Organizations of the Amazon Basin (COICA) and the Inter-American Development Bank (IDB), aims to put the people who actually live in this priceless environment at the heart of protecting it.

A special report assesses the threats of natural disasters and aims at developing strategies for the management of extreme weather events, such as wildfires, floods and droughts. Speaking from Queenland's Gold Coast, the head of the IPCC, Dr. Rajendra Pachauri, explained that there is increasing scientific evidence linking current climate change to extreme weather events.

Climate change awareness down in Europe

Climate change awareness down in Europe

Carbon dioxide may be harmful to the environment, but it seems Europeans also believe it to be harmful to their health! Three quarters of those surveyed even considered CO2 to be ''unhealthy'', while 9% said they thought it was flammable and 18% believed it be a water pollutant, none of which is accurate.

Soot and methane are climate-change causing pollutants that need bringing into any new international agreement on slowing global warming. So says a Policy Forum article in today's Science. With Kyoto due to expire in 2012, a replacement mechanism for regulating greenhouse gases is needed fast - and tackling soot and methane could speed up the payback of such an agreement.

Harvests of corn and wheat are already wilting under the rising temperatures seen since 1980, says a team from Stanford University. They publish their study results - which looks at what crop yields would have have been without climate change - today in Science Express. In contrast, rice and soya crops, and US farmers in general, are so far weathering the global warming storm - but that may be about to change.

Europe's climate fate decided by tussle between oceanic currents

A new player in Europe's climate change story, as global warming continues its relentless rise, has been suggested by a paper in today's Nature. The 'Agulhas leakage' of warm salty waters from the Indian Ocean, appears to be increasing, says the study - and that could help prevent the predicted slow-down of the North Atlantic Drift.

A drop in rainfall in March means water companies may be forced to bring in restrictions in the summer. Parts of the country had as little as 2mm of rain last month prompting warnings of potential droughts during the summer months. The dry month has led to a depletion in reservoir levels.

The phenomenon of a ''hole'' in the ozone blanket that covers the earth at polar latitudes was first discovered in 1985 by scientists from the British Antarctic Survey. The ''hole'' was a cylinder of the atmosphere, forming over polar regions, where the level of ozone in the atmospheric column was depleted.

Recent geoengineering conferences have raised the profile of how we might tackle global warming with a Plan B - finding ways to cool the planet down, whilst trying to agree on how to cut those pesky CO2 emissions. But could the Plan B of geoengineering be a dangerous distraction that ultimately locks us into a series of even greater risks?

Sea cow teeth from 50 million years ago are helping scientists to flesh out the climate of the earth during the Eocene, a time when greenhouse conditions reined supreme. Their paper, published today in Science, confirms that very wet conditions extended right down to the tropics, where rainfall rates were much greater than that seen today.
