Ancient forests stabilized Earths CO2 and climate

2014-01-23 17:59:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: UK researchers have identified a biological mechanism that could explain how the Earths atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU). As CO2 concentrations in...

Owen Paterson alarms campaigners with plan to build on ancient woods

2014-01-05 08:45:00| Climate Ark Climate Change & Global Warming Newsfeed

Telegraph: Developers will be given "carte blanche' to concrete over swathes of irreplaceable ancient woodland under proposals to ease planning restrictions on building in the countryside, campaigners have warned. Owen Paterson, the environment secretary, is facing a backlash after suggesting that developers should be allowed to bulldoze historic woods to make way for new homes if they promise to plant trees elsewhere. MPs and countryside campaigners have reacted furiously to the plans, which they say...

Ancient farming seen curbing extinctions of animals, plants

2013-12-09 02:02:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: Ancient farming practices, such as raising fish in rice paddies in China or Aboriginal Australian fire controls, will get a new lease of life under plans to slow extinctions of animals and plants, experts said on Monday. Turning to traditional farming is seen as a way of limiting what U.N. studies say is the worst spate of extinctions since the dinosaurs vanished 65 million years ago, driven by a rising human population that is wrecking natural habitats. A 115-nation group seeking to protect...

Ancient Climate Data Entombed in Plankton Shells

2013-10-26 17:33:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: New research suggests a record of ancient climate change is embedded in magnesium deposits present in ancient plankton shells. With further research, scientists may be able to use these ancient plankton shells to establish climate variability in Earth's far distant past, as well as provide new methods of measuring ocean acidification and salinity in past oceans. The research, published in the journal Earth and Planetary Science Letters, reveals new insights on the state of the climate hundreds...

Magnesium In Plankton Shells Serves As Record Of Ancient Climate Change

2013-10-26 13:17:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: Climate change dating as far back as hundreds of million years ago was recorded in the shells of ancient oceanic plankton, according to new research published in the journal Earth and Planetary Sciences Letters. Typically, scientists analyze polar ice in search of information about the planets temperature and atmosphere, but the oldest Antarctic ice core records only date back to approximately 800,000 years ago. In the new study, investigators from the University of Cambridge Department of...
