Title of an editorial in the Washington Post from James E. Hansen, director of NASA's Goddard Institute for Space Studies. Hansen is releasing a study Monday that shows that the extreme weather effects we're seeing are caused by climate change and the severity of the problem is worse than predicted. http://www.washingtonpost.com/opini...d90-11e1-8e43-4a3c4375504a_story.html?hpid=z3 In a new analysis of the past six decades of global temperatures, which will be published Monday, my colleagues and I have revealed a stunning increase in the frequency of extremely hot summers, with deeply troubling ramifications for not only our future but also for our present. This is not a climate model or a prediction but actual observations of weather events and temperatures that have happened. Our analysis shows that it is no longer enough to say that global warming will increase the likelihood of extreme weather and to repeat the caveat that no individual weather event can be directly linked to climate change. To the contrary, our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. So, yeah, hopefully this will be enough to get people to stop bickering over whether it even exists and actually do something about it. It's not hopeless if we act soon, Hansen says. There is still time to act and avoid a worsening climate, but we are wasting precious time. We can solve the challenge of climate change with a gradually rising fee on carbon collected from fossil-fuel companies, with 100 percent of the money rebated to all legal residents on a per capita basis. This would stimulate innovations and create a robust clean-energy economy with millions of new jobs. It is a simple, honest and effective solution.
