Here at Bitsofscience.org we’ve written quite extensively on why a direct shutdown of the Gulf Stream is unlikely – and that the collapse scenario featured in that one movie we only ever saw the trailer of probably did not even occur during the famous Younger Dryas ice age hick-up and that perhaps the Gulf Stream was just as strong during the ice age cold peak.
But forget about ice ages for as long as you, your grandchildren and their grandchildren will live – if Holocene Mass Extinction even grants us that time. We have a very different planet now, one that is exceedingly breaking all heat records. What we at Bits of Science have thus far largely ignored is that a gradual shutdown is probably equally bad news for anyone anywhere on the planet – and that science says that scenario is perhaps already underway:
The August 2015 global data of NOAA (full report) are just in. It was another record-hot month – the hottest August ever measured – already the 6th month of 2015 to be higher than any other previously recorded (February, March, May, June, July, and August).
We now know – after also record-hot months of June and July that the entire summer season of 2015 was globally the hottest summer the world has ever seen. 2015 is well on its way to become the hottest year ever measured, as we predicted quite some time ago.
In 2014 a Stanford University research group reviewed 55 scientific studies to investigate wether climate change significantly increases the risk of intergroup conflict. There conclusion is that it does:
Climate change not only causes decreased agricultural production due to droughts and desertification in Mediterranean North Africa and the ‘Fertile Crescent’ of the Middle East – it will also cost the region several thousands square kilometers of its most productive cropland as a direct result of sea level rise in the Nile Delta – and possibly a much larger area at risk of upstream storm surge floods.
From that same Nile Delta millions of people would have to be displaced, when the sea level rises by just 50* centimeter.
Over 2006 to 2010 a prolonged drought, unprecedented in modern documented history, caused a farming collapse in Northeastern Syria. Winter rainfall in the otherwise green & productive ‘Fertile Crescent’ decreased by at least a third in Syria (and up to 70 percent in Iraq).
Ten years after Katrina* the world is on the brink of a whole new cluster of climatic disasters, including wide-spread coral bleaching, Pacific atol floods, possibly another devasting Brazil drought and another record-breaking hot year, following from the currently developing Super El Niño.
Another devastating Atlantic hurricane will most likely not be a part of disrupting extreme climate events this year. These five images tell you why:
