The scientists do indeed know. The scientific consensus is that sea levels will rise by a meter or 2 over the next 200 years, and cause damages measured in the couple trillions of dollars. This is all laid out in the IPCC report. Thats a lower cost than an Iraq war.

That is the scientific consensus of the IPCC, which is the official authority on climate change. And the scientific consensus is that the world is definitely not going to end, nor is it even going to come close. Listen to the science and the scientific consensus!
