"A lack of international will means the chances of bringing climate change under control may already be "slipping out of reach", scientists have warned.
"A study by the Swiss science university ETH Zurich shows that, without an early and steep cut in greenhouse gas emissions, global temperatures are not 'likely' to remain less than 2C higher than pre-industrial levels. The 2C target, which experts say is needed to avert dangerous climate change, was agreed by the UN climate conference in Copenhagen in 2009.
"... Scenarios showing peak emissions around 2030 were likely to keep warming below 3C, but would miss the 2C target. Another study published in Nature Climate Change suggests that if greenhouse gas emissions continue to rise, the 2C threshold could be crossed between 2040 and 2060. This is well within the lifetime of many people alive today."
