 range of temperature increase due to climate change. If we hit the sort of estimates we have of how hot the Earth's going to get by the end of the century, some say about 2.6, 2.7 degrees from the pre-industrial average, that crosses all sorts of adaptation limits, right?

But within current circumstances, there are plenty of options to deal with this.
