The earth is cooling, we’re all going to die! Whoops! The earth is warming, we’re all going to die! Whoops! The earth is cooling, we’re all going to d…..

Perhaps nobody embodies the farce of supposed man-made global warming better than John P Holdren. “Who he?” you may ask. Yup, till yesterday, I’d never heard of him either. But he’s a pretty important person. As far as I can see, he’s still President Obama’s chief scientific adviser and he specialises in climate change – in particular supposed man-made global warming.

So what? you might think. Well, in the 1970s, Mr Holdren was already writing and teaching about climate change. Only at that time, he was absolutely convinced that we were going into a mini-ice-age. here’s a typical quote from one of Mr Holdren’s books:

“The effects of a new ice age on agriculture and the supportability of large human populations scarcely need elaboration here. Even more dramatic results are possible, however; for instance, a sudden outward slumping in the Antarctic ice cap, induced by added weight, could generate a tidal wave of proportions unprecedented in recorded history”.

So, there you have it – global cooling would lead to crop failure, mass starvation and flooding. In fact, in one of his books Mr Holdren and his co-authors proposed population control measures such as mass sterilisations for people who were “overproducing children” as a way to help mankind survive the lack of food due to the coming ice age.

Anyway, here we are forty years later and Mr Holdren is, as far as I can make out, a fervent believer in man-made global warming. Yes, this is the same Mr Holdren who was once a fervent believer in global cooling.

Now you could say that president Obama’s scientific adviser is an honest man who changes his opinion as the facts change. Of you could say he’s a fraud who just jumps on the latest bandwagon in order to further his own career. Given that the earth has not warmed for the last thirteen years, I wonder if Mr Holdren will change his highly educated mind yet again?

I’ll end with a couple of quotes from leading global warmists

“Unless we announce disasters, no one will listen” Sir John Houghton First chairman of the IPCC Scientific Working Group

“To capture the public imagination we have to offer up some scary scenarios, make simplified dramatic statements and little mention of any doubts one might have” Dr Steven Schneider

Incidentally, John P Holdren and Dr Steven Schneider were reported to be key figures in attacking Bjorn Lomborg when he published his book The Skeptical Environmentalist
