COMMENT POSTED TO AN ARTICLE BY IAN JOHNSTON IN THE INDEPENDENT

 

‘I agree that the effects of a changing climate — such as increased maritime access to the Arctic, rising sea levels, desertification, among others — impact our security situation’

This, actually, is not news.

The Pentagon issued official reports on this matter years ago. At any rate, it is kind of stating the obvious when you are discussing things like shorelines or temperatures or precipitation.

Perhaps, Gen. Mattis was in a high position there then.

The issue has never been, I would like to remind Independent editors, whether there is climate change or not.

There is, and always has been climate change. Tacitus, two thousand years ago, wrote of North Africa as “the granary of Rome.”

The issue is whether the particular change we think we see today is caused by human acts.

That is quite a different matter, almost always glossed over by enthusiasts. And it has not been scientifically proved.

And there is an even greater, less certain issue, and that is whether what we think we see can be, in any way, affected by our society’s deliberate acts.

That is a totally unanswered question, and it ain’t trivial when you are talking of vast projects and plans on a planetary scale, costing trillions of dollars.
