Ancient DNA holds clues to climate change adaptation (PhysOrg.com) -- Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change. The bones play a key role in a world-first study, led by University of Adelaide researchers, which analyses special genetic modifications that turn genes on and off, without altering the DNA sequence itself. These 'epigenetic' changes can occur rapidly between generations - without requiring the time for standard evolutionary processes. Such epigenetic modifications could explain how animal species are able to respond to rapid climate change. In a collaboration between the University of Adelaide's Australian Centre for Ancient DNA (ACAD) and Sydney's Victor Chang Cardiac Research Institute, researchers have shown that it is possible to accurately measure epigenetic modifications in extinct animals and populations.
Nasa-funded study: industrial civilisation headed for 'irreversible collapse'? A new study partly-sponsored by Nasa's Goddard Space Flight Center has highlighted the prospect that global industrial civilisation could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution. Noting that warnings of 'collapse' are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that "the process of rise-and-collapse is actually a recurrent cycle found throughout history." Cases of severe civilisational disruption due to "precipitous collapse - often lasting centuries - have been quite common." The independent research project is based on a new cross-disciplinary 'Human And Nature DYnamical' (HANDY) model, led by applied mathematician Safa Motesharrei of the US National Science Foundation-supported National Socio-Environmental Synthesis Center, in association with a team of natural and social scientists.
EURASC - Symposium Thank you to Mr. Sebastien Hervé (Université de Bretagne Occidentale, Brest, France) for the pictures. 2015 is a special year with the upcoming Climate Conference (Conference of Parties, COP21) in Paris in December. Its goal is to reach a global agreement to mitigate and adapt to climate change as part of the United Nations Framework Convention on Climate Change. Hence, EURASC has focused our 2015 meeting on â€œClimate change: impacts on ocean, food production, health and the economyâ€. Global warming is now slowing down the circulation of the oceans — with potentially dire consequences This NASA animation shows what happens globally to create the large, slow current called the thermohaline circulation. (NASA) Welcome to this week’s installment of “Don’t Mess with Geophysics.” Last week, we learned about the possible destabilization of the Totten Glacier of East Antarctica, which could unleash over 11 feet of sea level rise in coming centuries.
How We Made the 3D Tour de France Interactive WebGL and GPS data recreate an iconic stage of the race In sports coverage, interactives can convey an event's intensity while also allowing the user to participate. As we considered an interactive for the Tour de France, we knew we wanted something fun and compelling, an interactive that would combine quality writing and photography with real-world data. So we thought about a 3D representation of the most grueling stage, Alpe D'Huez. It’s a 13.8 km climb up 21 hairpin bends to the finish at an altitude of 1,850 m.
Watch 131 Years of Global Warming in 26 Seconds Don't Have Flash? Watch this video on your iPad or iPhone here While temperatures soared for many this summer, this video takes the longer historical view. It comes to us from our friends at NASA and is an amazing 26-second animation depicting how temperatures around the globe have warmed since 1880. That year is what scientists call the beginning of the “modern record.”
News - Mysterious new man-made gases pose threat to ozone layer 9 March 2014Last updated at 14:09 ET By Matt McGrath Environment correspondent, BBC News Dealing with the hole in the ozone layer has been one of the most successful international science projects Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer. What's Really Warming the World? Climate deniers blame natural factors; NASA data proves otherwise Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies."

(define) Definition of Global Warming Definition of Global Warming: A gradual increase in the earth's average surface temperature. Common-usage definition: Warming caused by human activity. Technical term for this: Anthropogenic global warming. Definition of Greenhouse Gas: A gas, like CO2, which traps the sun's heat. The debate: Is the observed global warming natural or man made?
