Green light: Climate wars, birdwatching and Fairtrade chocolate

Climate wars • Leaked climate change emails scientist 'hid' data flaws • Climate change emails between scientists reveal flaws in peer review • Climate change email scandal shames the university and requires resignations • How the 'climategate' scandal is bogus and based on climate sceptics' lies • Global deal on climate change in 2010 'all but impossible' This week we launched a major investigative series looking at the inner workings of climate science. The leading environment reporter Fred Pearce examined the procedures of the science and allegations by sceptics – and found both wanting. We also looked in depth at the likelihood of a global climate deal in 2010 after the weak accord reached at Copenhagen. The prognosis is not encouraging: a deal is seen as "all but impossible".

Everybody's talking about If you only read one thread... Feed-in tariffs are disappointing for local renewable energy Simon Hughes: The government's feed-in tariff plans keep Britain far behind Europe on renewables, and panders to big energy companies Best comment Join us live online for the RSPB's Big Garden Birdwatch ThomasReturns : I did a few things suggested on the RSPB web site when it started snowing. Bird food here and there as per their instructions. It was all going fine until early this week when a sparrowhawk turned up, which I've never seen in the garden before.
