Rising Levels of Human-Caused Water Vapor in Troposphere will Intensify Climate Change Projections

Posted July 28th, 2014 at 7:01 pm (UTC+0)
3 comments

When it comes to greenhouse gases that contribute most to global warming, most people think of substances such as carbon dioxide, methane or even hydrofluorocarbons. But did you know that, for a while now, scientists have considered the vapor of the most important ingredient in sustaining life on Earth – water – as one of […]

New Dating System Could Reveal Secrets of Earth’s Ancient Climate

A new study shows changes in precipitation are affected by human activities and can’t be explained by natural phenomena, such as El Niños and La Niñas. Scientists from the Lawrence Livermore National Laboratory in California published the study in the Proceedings of the National Academy of Sciences. The researchers suggest two mechanisms will probably cause […]

Chicago researchers have made significant progress developing prosthetic limbs that can feel and touch. Writing in the Proceedings of the National Academy of Sciences, the researchers say they’ve established a foundation to develop touch-sensitive prosthetic limbs. This research could lead to a direct interface with the brain that could someday allow those who have lost […]

Scientists say they may have found a link between a dramatic climate shift nearly 13,000 years ago and an asteroid or comet that struck the Canadian province of Quebec. Researchers at Dartmouth College say the comet/asteroid strike took place at the beginning of a global cooling event known as the Younger Dryas stadial or the […]

Study: Diet Changes May Have Been Crucial Step in Becoming Human

A change in  diet about 3.5 million years ago  may have  set hominid species on a path to becoming  human, according to a study led by the University of Colorado, Boulder. Scientists conducted high-tech tests on the tooth enamel found in  remains of ancient hominid species. The results indicated that, prior to that dietary change, […]

Living Microorganisms Found High Above Earth
