Will extreme weather like super typhoon Haiyan become the new norm?Meanwhile, from COP19: Kicking the Can Until It's Too Late
Christiana Figueres, the UN's leading climate official, said: "We have seen essential progress. But let us again be clear that we are witnessing ever more frequent, extreme weather events, and the poor and vulnerable are already paying the price. Now governments, and especially developed nations, must go back to do their homework so they can put their plans on the table ahead of the Paris conference."
Climate scientists are confident in three ways that climate change will make the impacts of hurricanes worse. First, global warming causes sea level rise, which amplifies storm surges and flooding associated with hurricanes
. As a paper published in the Proceedings of the National Academy of Sciences
by Aslak Grinsted and colleagues concluded,"we have probably crossed the threshold where Katrina magnitude hurricane surges are more likely caused by global warming than not
as climate scientist Kevin Trenberth has noted, global warming has also increased the amount of moisture in the air, causing more rainfall and amplifying flooding during hurricanes
.Third, warmer oceans are fuel for hurricanes
. Research has shown that the strongest hurricanes have grown stronger in most ocean basins around the world over the past several decades, and climate models consistently project that this trend will continue. Chris Mooney recently documented the past decade's worth of monster hurricanes around the world, and Jeff Masters estimates that 6 of the 13 strongest tropical cyclones on record at landfall have happened since 1998.http://www.skepticalscience.com/will-super-typhoon-haiyan-become-norm.html #ClimateChange #IneptLeadership #ClimateCrisis
