Global warming was forecast a century ago

I retweeted this 1912 press cutting yesterday morning and immediately wondered whether I had been taken in by a hoax.

But it does appear to be genuine. It comes from the Braidwood Dispatch Mining Journal, which was published in New South Wales.

So take it as a reminder of how well established the science behind fear about global warming is.

The agreement on the climate signed in Paris was immensely welcome, though I fear some governments will expend considerable energy on trying to wriggle out of what they agreed to over the coming years.

And the controversialists and backers of dirty industry will continue to doubt the science. But as Upton Sinclair said:

It is difficult to get a man to understand something, when his salary depends on his not understanding it.
