Indeed. It appears to be limited to about 22C where as current global average temperatures are about 15C. It might also take a few million years to get to 22C. It will get there a lot sooner if we carry on the way we are.

Will rising sea levels be a problem in the developed world sooner than we expect...

It's well known some mortgage companies won't lend on leasehold properties that have less than 60-70 years on their lease remaining. Could your seaside or riverside property be flooded in 60-70 years? How long before mortgage companies wake up to the fact that many freehold houses are really leasehold with Poseidon owning the lease? They could suddenly decide not to lend on such properties overnight. You might not have 60-70 years before the value is impacted.

Is "cwatters" an ironic handle?

In any case, maybe it's better that we get over the warming hump now, while we have plentiful fossil fuels, a relatively small population (only 7 billion) and a fairly healthy world economy, and reasonably peaceful (the odd skirmish here or there notwithstanding).

If we had to do this say 200 years from now and the human race is not in such good shape, we might not survive (as a species).

"Bring it on!", I say.

A hump, by definition, has an up followed by a down.

What leads you to believe that global warming will follow that profile in any realistic timeframe ?

And there I was thinking that most mortgages were longer term, 10 - 30 or so years!:ok:

So you've got to wonder how much longer banks will continue to give 25-30 year mortgages on seaside properties (leasehold or freehold) because 30+40=70 which takes us to 2089.

This issue occurred to me after I had to help someone extend a 70 years lease. The extension cost about £16,000. Negotiating with Poseidon would be a lot harder.
