Have you taken a leaf out of Hymies book on You tube vids :-)

[ToraToraTora]

it seems to be the way YMB!

[youngmafbog]

Nice Jasper there TTT, one of your evictees?

[ToraToraTora]

No they don't like me any more!

[ClareTG0ld]

Catt's talking nonsense.

Only in your opinion.

Which is wrong.

[Old_Geezer]

If just highlighting something, with no wish to get stuck in debate, posting a relevant video is no bad idea. Others need not watch if uninterested. It's when it forms part of a debate to make one's case for one, that it's less wonderful; especially if done often.

[ClareTG0ld]

// Only in your opinion.

Fist of all, it's not really my opinion is it, it's the IPCC's opinion. Secondly, it's not an opinion, it's the scientific consensus and is at this point as well-established as General relativity.

[Old_Geezer]

Not read all of that link but since it starts by stating that climate change denial is being pushed, which it clearly isn't, it doesn't give much incentive to continue.

[ClareTG0ld]

Taking data out of context and using it to argue that there is basically nothing exceptional about today *is* "denialism", no two ways about it. When Catt talks about how things were two degrees warmer in Egyptian and Roman times, he's anyway mistaken, but to the extent that he *does* have a point it's a reference to the "Roman Warm Period", a favourite of denialists, who seem to miss that it was a local phenomenon rather than a global one. In that sense it's not that much different from denying that Southern Europe's recent heatwave is unusual because it regularly exceeds 50 degrees C in Death Valley.

Are there records I can view from the rest of the world at the time of the 'local event'?

Not cave drawings or folk tales mind, actual records.

Thank you.

[naomi24]

Do we know how warm Death Valley was Roman times when the whole of the known world could reasonably be described as ‘local’?

[ClareTG0ld]

douglas, you can refer to the latest IPCC Review (Sixth Assessment Report), for a record of global average temperatures, and how they are determined.

// Do we know how warm Death Valley was Roman times when the whole of the known world could reasonably be described as ‘local’? //

There were civilisations and peoples across the entire world in Roman times, so, no, the "known world" couldn't be reasonably described as local.

[naomi24]

ClareTG0ld, I’m well aware of that, but that world wasn’t known to the Romans so if you claim it was only ‘local’, where are the records for whatever was going on elsewhere?

[Atheist]

What a coincidence! Man-made climate change doesn't exist, and that fits in perfectly with those who want to keep their cars running and uppity teenagers to be put in their place, and holiday flights to continue, and nothing painful ever to happen again if only we were rid of communists and immigrants.

[douglas9401]

Here be dragons. :-)

[ClareTG0ld]

Naomi (and others): I think it's best to refer you to the full IPCC report, which hopefully explains better than I can how these things are detemined. See https://www.ipcc.ch/report/ar6/wg1/ and the various files there. If you'd rather wait for me to summarise, I'm busy the rest of the day so won't get around to it until much later.

[naomi24]

ClareTG0ld, speaking for myself, I don’t need that report or for you or anyone else to summarise. I just wanted an answer to my question which you don’t appear to be able to provide. I actually think you’re very wrong to claim that it was just ‘local’ when it seems you really don’t know that.

[Atheist]

Naomi et al. Which physicists do you choose to believe, and why? Is it coincidence that petrolheads choose one sort of physicist and those with children dead from flood, pollution and crop failure etc choose different physicists?

[ClareTG0ld]

It's basically the job of that report to detail (a) what we know, (b) how we know it, and (c) what we still don't know yet. So that's literally the best place to go. As to whether I personally "know" or not, I did look it up before posting; my source is below.
