Ice Cores Show Volcanoes Cooled Earth Less Than Estimated

LiveScience: Global cooling caused by some historic volcanic eruptions wasn't as extreme as climate scientists recently thought, according to newly revised ice core records from Antarctica. Volcanic eruptions blast sulfur-dioxide gas into the stratosphere, where it turns into tiny particles called sulfate aerosols that reflect the sun's energy and cool the Earth. Snow falling in Antarctica records the levels of sulfate in the air at the time, and it eventually becomes ice drilled by researchers in long, tubular...

Lord Stern: climate change risks greater previously estimated

Blue and Green: The risks associated with climate change are greater than previously estimated because the model currently used fails to take into account the latest findings, according to research from Dr Simon Dietz and Prof Nicholas Stern of the Grantham Research Institute on Climate Change and the Environment. Stern conducted a 2006 review looking at the economics of climate change, from a wide range of angles, such as water resources, food production and health. In it, he argues that climate change is the...
