Why 2°C Global Warming is Highly Dangerous

Recently, James Hansen the former director of NASA GISS published new study findings about future sea level rise, ice melt, and temperature changes, as well as the possible implications for future climate. Above video highlights a part of a talk Hansen held on December 1, 2015 at the Paris climate change conference (COP21). The take…

Sea Level Rise Projections until 2100, a nonlinear response?

Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…

World’s Greatest Crime Against Humanity And Nature

By James Hansen: As I peer through Beijing’s impenetrable smog I feel nauseous. I have long been troubled by the injustice of human – made climate change to our children and grandchildren, which may soon constitute a tragedy of epic proportions. Now I stare in the face of another tragedy. Air pollution from coal kills over…

Heatwaves blamed on Global Warming

Unusually high frequency points to human influence | NASA climatologist James Hansen made headlines during the US heatwave of 1988, declaring in testimony to Congress and during interviews on prime-time television that a build-up of greenhouse gases was increasing the probability of weather extremes. Now, as much of the United States sizzles through another torrid…
