Chris says it's the coolest it's been for 65 million years

It's not the coolest it's been in 65 million years. It was getting cooler, but for the last 150 years it's been warming, and it's been warming relatively quickly.

And which "climate doomers are telling us it's too hot"?

Those of us who are looking at what is happening are aware that it's not as simple as "it's too hot".

Too hot for what?

Too hot where?

We're saying it's warming, and it's going to keep warming unless we do something about it.

US domestic migration

Chris seems to believe that a prime indicator of a climate crisis would be that domestic migration in the US would "change direction" - or perhaps stop?

With less than 5% of the world's population, a habitable and primarily benign climate almost everywhere (exceptions e.g. Alaska accepted) climate-related migration within the US would not seem to me to be the first place to look for signs that the current level of warming is having an effect.

However, a less naive person than Chris would look for evidence in areas that are already warm - and there is plenty more - and start to at least monitor the situation.

The need for fossil fuels

If it's as simple as Chris's understanding tells us and that we can't inhabit higher lattitudes without fossil fuels, we're in a "cleft stick", aren't we?

If there are elements of mankind's ability to live on this planet that mean we cannot do without fossil fuels, then surely we need to reduce the use of fossil fuels to the bare minimum?

Wait until it's too late

The last "gem" from Chris is perhaps the most outrageously naive and misguided of all.

Don't even recognise there's a problem until heat deaths have massively increased and mass migrations within the US to cooler locations are under way.

You don't think it might be an idea to do something before that happens, Chris?
