Dr Michael E.Mann & Dr James Hansen 10ft sea level rise by 2050. #Auspol 

Next, we’re joined by Dr. Michael E. Mann, climate scientist, Distinguished Professor of Meteorology and Director of the Earth System Science Center at Penn State University, creator of the infamous “Hockey Stick” graph, and author of more than 160 peer-reviewed publications, as well as the book The Hockey Stick and the Climate Wars: Dispatches from the Front Lines to discuss last week’s “bombshell” new study from NASA’s former chief scientist Dr. James Hansen, warning that sea level rise of 10 feet or more is likely to happen much sooner than scientists previously expected. It could happen even as early as 2050.
Mann tells me Hansen’s disturbing study suggests that “climate change is proceeding faster, and it’s larger in magnitude than what the IPCC [UN’s Intergovernmental Panel on Climate Change] reported. And that’s been true at every juncture. We have tended to underestimate the rate and magnitude of the changes…What Hansen has shown is that indeed there is reason to at least suspect the possibility of a worst case scenario that is a lot worse than anything the IPCC talks about.”
We also discuss the politics of this entire fine mess and the irony of 2016 GOP Presidential candidates Jeb Bush and Marco Rubio, both of Florida, denying the realities of the science — each in their own way — as their own state will be among the first to begin to disappear. That, of course, is only if Hansen is right — as he has been in pretty much every case since he first rang the alarm about global warming in the U.S. Senate back in 1988.
“If we had acted when we already knew that there was a potential problem [back in 1988],” says Mann. “If we had acted then, then the emissions curve would be a bunny slope…a pretty gradual, smooth transition. It wouldn’t be very hard to do, it wouldn’t be very expensive. Instead, what several decades of delay have bought us is that we now face the black double diamond slope. That’s what we’re confronting now.”
Listen to the entire conversation, please. It’s really important and Mann — who actually is a scientist (hint, hint, GOP candidates!) — knows what he’s talking about.
