| Arctic climate changing fast Climate change is transforming the Arctic environment faster than expected and accelerating the disappearance of sea ice, scientists said on Friday in giving their early findings from the biggest-ever study of Canada's changing north. The research project involved more than 370 scientists from 27 countries who collectively spent 15 months, starting in June 2007, aboard a research vessel above the Arctic Circle. It marked the first time a ship has stayed mobile in Canada's high Arctic for an entire winter. |
| Alternative Energy Grows in Europe Wind and solar technology made up over half of Europe’s new electricity generating capacity in 2009, as the number of new coal and nuclear facilities fell More wind capacity was installed in Europe during 2009 than any other electricity-generating technology, according to statistics released today by the European Wind Energy Association (EWEA). Wind accounted for 39 per cent of increased European energy capacity, ahead of gas (26 per cent) and solar (16 per cent). In contrast, the nuclear and coal power sectors decommissioned more megawatts of capacity than they installed in 2009, with a total of 1,393 MW of nuclear and 3,200 MW of coal decommissioned. |
| California's global-warming law Under Attack Republican politicians and conservative activists are launching a ballot campaign to suspend California's landmark global-warming law, in what they hope will serve as a showcase for a national backlash against climate regulations. Supporters say they have "solid commitments" of nearly $600,000 to pay signature gatherers for a November initiative aimed at delaying curbs on the greenhouse gas emissions of power plants and factories until the state's unemployment rate drops. |
| Genes. Spots and Butterflies How different species can evolve the same colors and pattern has always puzzled biologists. Now, scientists at Cambridge University have found "hot spots" in the butterflies’ genes that might one of the most extraordinary examples of mimicry in the natural world. A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. |
