Here's a great read for the skeptics and contrarians and it's about a scientist who is one of your own:

"Prof Richard Tol predicts the downsides of warming will outweigh the advantages with a global warming of 1.1C - which has nearly been reached already.

Prof Tol is regarded by many campaigners as a climate "sceptic".

In academic circles, this is actually an uncontroversial finding."

But it is controversial for climate contrarians, who often cite Professor Tol's work to suggest that we shouldn't worry about warming.

"I am worried about how this work is being interpreted, by Lord Ridley. In my opinion, [CO2 fertilisation] benefit of greening is not worth the price of all the negative changes," he said".

"We emit nine gigatons of carbon per year from our burning of fossil fuels, but there's a 100 gigatons lying just under the Siberia tundra. You have many-fold larger stores of carbon in the topsoil of tropical soils, or under the ice in the Arctic.

"If we don't manage the living ecosystems well enough they could start biting us from behind."

and the temperatures when life was most abundant on earth was?

But there weren't any coastal mega-cities nor 7 billion humans all in need of food, water and natural resources.

its pretty simple really.................they will move

In a country like Bangladesh where exactly can they all move to? The only high ground are the countries next door!
