Global warming to breach 2C limit by 2050 unless tougher action: study

By Alister Doyle OSLO (Reuters) - Global warming is on track to breach a 2 degrees Celsius threshold by 2050 unless governments at least double their efforts to limit greenhouse gas emissions, scientists said on Thursday. Plans by almost 200 governments to cut greenhouse gases are far too weak to match targets set in a Paris Agreement on climate change last December for a drastic shift from fossil fuels towards greener energies, they said. "We've really got a problem," Robert Watson, a British-American scientist who was among the seven authors of the study and is a former head of the U.N.'s Intergovernmental Panel on Climate Change (IPCC), told Reuters.
