A new, detailed record of past climate change provides compelling evidence that the last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide. The finding is based on a very broad range of data, including even the shells of ancient tiny ocean animals.
Researchers have updated HadCRUT - one of the main global temperate records, which dates back to 1850. One of the main changes is the inclusion of more data from the Arctic region, which has experienced one of the greatest levels of warming. The amendments do not change the long-term trend, but the data now lists 2010, rather than 1998, as the warmest year on record.
Many bird species are unaffected by wind farms, concludes a study carried out by UK bird charities. Scientists with the British Trust for Ornithology (BTO) and RSPB found that building the turbines was more disruptive than operating them. Impacts varied between species, with red grouse numbers recovering after construction, curlews declining and not recovering, and skylarks increasing.
Talk about heat maps, and most people will assume you're referring to a map with colours used to represent intensity of something like poverty or crime. This new map - published his morning by the Department for Energy and Climate Change - is much more literal than that. It really is a heat map.
