Earth's ozone layer should eventually recover from the unintended destruction brought on by the use of chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals in the 20th century.

Combating climate change may not be a question of who will carry the burden but could instead be a rush for the benefits, according to new economic modeling presented today at "Climate Change: Global Risks, Challenges & Decisions" hosted by the University of Copenhagen.

After spending time at the largest gathering of world class climatologists, meteorologists, physicists, engineers, and economists, among other very brainy folks, I came away with the feeling that the battle remains joined by this hearty group, otherwise derided as skeptics and deniers of global warming.

Climate change concerns like melting icecaps, increased desertification, loss of coral reefs and the extinction of species like polar bears can seem a distant concern in our everyday lives. Little attention, however, has been paid to the likelihood of increased bills, through tax and insurance charges, that will be incurred as the UK climate changes.

Climate change will not be taken seriously until the media highlights its significance, say researchers at the University of Liverpool.

Richard Hawkins, Canada Research Chair in Science, Technology and Innovation Policy, says there is no evidence that information technologies necessarily reduce our environmental footprint. His research will provide input into the OECD (Organization for Economic Cooperation and Development) initiative on IT and sustainability at the United Nations' Climate Change Conference in Copenhagen, Denmark later this year.

High summer temperatures, pushed higher by global climate change, may bring with them a spike in hospitalizations for respiratory problems, according to an analysis of data from twelve European cities, from Dublin to Valencia.

If nothing is done to substantially reduce greenhouse gas emissions, Washington is likely to experience some $3.8 billion in associated annual costs -- including $1.3 billion in health related costs alone.

The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State.

In 2007, researcher David Lewis of The Mind Lab knew that chocolate kindled natural anti-depressants in the brain such as serotonin, but was stunned to find that people registered greater brain activity and higher heart rate from eating chocolate than passionate kissing.

Two BYU researchers who just returned from Antarctica are reporting a hardy worm that withstands its cold climate by cranking out antifreeze. And when its notoriously dry home runs out of water, it just dries itself out and goes into suspended animation until liquid water brings it back to life.

Scientists have recovered fossils of a 60-million-year-old South American snake whose length and weight might make today's anacondas and reticulated pythons seem a bit cuter and more cuddly.
