It was warmer in this country in Roman times. What caused that, all those 4WD chariots?

Your jest may well be closer to the truth than you might think.
The well known "greenhouse gas" methane is a known contributor to atmospheric warming. After cattle, equine flatulence is plentiful,
Man-made global warming my a***. It's them pre-industrial revolution ancient Roman 'osses wot done it, tha' knows. :emoticon-0100-smile:emoticon-0105-wink::emoticon-0105-wink:

Didn't read all that, Eng on tv, but I'd guess Trump believes whatever he thinks he should believe to hang on to power.

Not to dip my toe in forbidden politcal waters, but those who wish to understand JT have learned to observe what he does, not what he says. Don't expect American involvement in global climate change initiatives over the next four years. I'm happy with that, and I say that as CEO of a green energy company.

Geologists reckon the planet was 8 degrees warmer and carbon in the atmosphere was double what it is now, this in the Cretaceous period. The Greeks in 400/500 bce talk of islands disappearing under rising sea levels. As has been said Britain was warmer 300/400 ce. We had a mini ice age around 1350 ce and again in the mid to late 19th century. Carbon in the atmosphere has risen by 0.01% over the last 30 years. NASA say the whole solar system is warming up. The reasons for climate change? I’m ****ed if I know. What I do know is that politicians and the ruling elite are quite happy to impoverish the rest of us for their own furtherance in the back of it.

Regarding temperature and your quoted figures, i would guess the worry is that it took 100 million years to cool down those 8 degrees and just 50 years to warm up again by 2.5 degrees, and so it's the speed that implies the hand of man has had an effect, plus the time it takes for us to adapt.

Either side of the argument, fossil fuels will eventually run out or be too expensive to extract and so it is stupid to wait until this point to develop other sustainable fuel sources. Every country should want to be largely energy independent for security and safety reasons.

Another thing is that it clearly isn't good for the planet producing billions of tonnes of crap and just burying it or chucking it away after short periods of time. So better to think more sustainable.

*Carbon in the atmosphere has risen by 25% in the last 30 years.

The scale of the X axis on this graph gives the impression that current temperature rises have happened at a similar rate throughout history. Produce the graph on a more meaningful scale and those historical gradients would flatten out significantly. Not so the current one.

Would that make them read 'hotter'?
