MIT: Global Warming of 7°C ‘Could Kill Billions This Century’

Some readers may remember the 1961 film “The Day the Earth Caught Fire”. It could be viewed as the original “climate alarmist” film as it contains all of the plot elements of our current climate alarmism scenarios: exaggerated images of a dying planet, a mainstream media newspaper reporter, technology that is feared, the Met Office, and last but not least, junk science.

You can read about the whole wacky plot here.
Back to the present.

A new study out of MIT predicts “a 90% probability that worldwide surface temperatures will rise at least 9 degrees by 2100.
This is more than twice what was expected in 2003. The Telegraph reports

Global warming of 7C ‘could kill billions this century‘. Global temperatures could rise by more than 7C this century killing billions of people and leaving the world on the brink of total collapse, according to new researchA similar 2003 study had predicted a mere- but still significant- 4 degree increase in global temperatures by 2100, but those models weren’t nearly as comprehensive, and they didn’t take into consideration economic factors.

So what has changed since 2003 to cause the scientists at MIT’s “Centre for Global Climate Change” to believe the world is going to boil over this century and send billions of us directly to a toasty demise similar to our featured movie?  

Since 2003, global temperatures have been dropping.

Arctic ice extent is at the highest late May levels in the AMSR-E satellite record.

Antarctic ice has broken the record for greatest extent ever recorded.

January, 2008 broke the record for the most snow covered area ever measured in the Northern Hemisphere.

I added a red line below showing the reported projected rise in temperatures from the MIT models, compared with the actual observed temperature trends since the previous 2003 report. Their projections show a correlation of essentially zero.WFT_goddard_mit_temptrendGiven that the observed trends are exactly opposite what the MIT models have predicted, one might have to ask what they have observed since 2003 to more than double their warming estimates, and where their 90% confidence value comes from? 

 

The study, carried out in unprecedented detail, projected that without “rapid and massive action” temperatures worldwide will increase by as much as 7.4C (13.3F) by 2100, from levels seen in 2000.

This study has a strong scent of GIGO (garbage, in garbage out.) MIT has one of the world’s preeminent climatologists Dr. Richard Lindzen in their Department of Earth, Atmospheric and Planetary Sciences. I wonder if the scientists at the “Centre for Global Climate Change” checked with him before firing this remarkable piece off to the press?

During the Phanerozoic, CO2 levels have at times been more than 1,500% higher than present, but temperatures have never been more than 10C higher than present. So how does a projected 30% increase in CO2 produce a 7C temperature rise in their models? During the late Ordovician, there was an ice age with CO2 levels about 1000% of current levels. Hopefully the newspaper headlines don’t accurately represent the content of the article.

Finally, does their name (”Centre for Global Climate Change“) hint at a possible inherent bias in their raison d’être? What rapid and massive actiondo they want us to engage in?
