NASA’s Jim Hansen goes there: Texas summer ‘was a consequence of global warming’: ‘In new paper he directly & without equivocation ties Moscow (2010) & Texas (2011) heat waves to climate change’
Hansen: 'There is no need to equivocate about the summer heat waves in Texas in 2011 and Moscow in 2010, which exceeded 3σ – it is nearly certain that they would not have occurred in the absence of global warming. If global warming is not slowed from its current pace, by mid-century 3σ events will be the new norm and 5σ events will be common'
