Dust Bowl, Miocene oddity

17 October 2014
Climate change

At http://phys.org/print332601657.html … the discussion here is the dust bowl of the 1930s – a period where temperatures matched those of the 1990s. It was essentially a prolonged period of dry weather in a particular part of N America. The question is – are there any similarities with modern weather patterns?

At http://phys.org/print332519803.html … it seems computers can now tell us about co2 levels as long ago as the Miocene – 15 to 17 million years ago. Of course, this is all about projection – but never mind. An article in Paleoceanography says that climate shifts in the Miocene was matched by co2 levels. Conveniently, and therefore ambitiously, the authors claim this has doomsaying repercussions, as co2 levels in the Miocene are said to be close to those projected to arise at the end of this century, AD2100. Who believes this sort of thing?

The article also claims co2 levels have a connection with the Ice Ages – and any semblance of rationality goes out of the window. Models really are dire.

(note … the assumption is that co2 causes temperatures to rise and therefore to decline. Funny that temperatures are stagnant at the moment but co2 levels are climbing).
