Climate Science Is Settled

Certain authorities keep trying to convince us that the science of climate change is settled. So why is it that climate scientists continue to reach opposing conclusions?

You may remember research from last spring indicating that increases in vertical wind sheer – differences between the upper and lower levels of the atmosphere in wind direction and speed – could counter-balance the effects of warming waters. Although conventional wisdom suggests that global warming could result in more powerful storms, examination of 150 years of hurricane records in fact reveals a small decline in hurricanes making landfall in the United States as oceans warmed. This latest inconvenient observation apparently triggered "lively debate" at the annual meeting of the American Meteorological Society.

Little wonder the majority of people remain sceptical† about the severity of claims made by politicians and the media!

† A global survey conducted last year concluded that just one in five believe human causes are the main factors driving climate change.

On a recent visit to Mexico Archeological sites, we were assured by the guide that the Mexican Mayan civilisation predicted the end of the human race on 21 December 2012; also that the Egyptians using similar mathematical equations (1000 year later?) depicted the end of humanity on 22 December 2012.

We all decided to hedge our bets and not purchase Christmas presents until 23rd December that year, just in case they - or the global warming predictors - are correct!!
