What was it like the last time CO2 levels were this high?

'The research, published in Csank et al 2011, uses two independent methods to measure Arctic temperature during the Pliocene, on Ellesmere Island. They find that Arctic temperatures were 11 to 16°C warmer. This is consistent with other independent estimates of Arctic temperature at the time. Global temperatures over this period is estimated to be 3 to 4°C warmer than pre-industrial temperatures. Sea levels were around 25 metres higher than current sea level'.

Can we come and stay at your gaff? We'll bring the PV and the woodburner...

You don't have to do that, Candy. Technology will save us all.

My house is at 30 metres. My work is at 15 metres...
Far too close for comfort.

Where's that interactive map (moving a slider calibrated in metres) which shows the effect of sea level rises? Anyone remember?

The interactive map that I use only goes to 14 metres above present and that is bad enough for the UK. That probably does for all the nuclear sites bar Trawsgwynnyd (spelling) which is inland on a lake.
And there was me thinking that we might have a beach front property one day. But that would require 90m rise. Maybe great great grandchildren will be able to enjoy that.

I'd still have an acre or so left at 60m!

That might be the one, JohnB. Thanks. Pity it doesn't show +25 metres, which is what this thread is about. At +20 metres, the coast would be half a mile from me.
At +30 metres, I would be the coast.

They've upgraded that map since I last used it. At sixty metres we are only a couple of miles from the coast and Oxford is a sea side town!

Yes!
Slight problem is that I may have 55m other people to accommodate in my attic.

At 20M I'm on an island and at 30M I am paddling...

Count yourself lucky. My flat is at 5 metres. Still, at least it's upstairs.
