This is meant to be more of a question than a debate, but my understanding is advances in renewables mean we may be able to keep warming down to 3C or so by 2100.

What would this entail? Would large amounts of cropland become barren or would we still have more than enough room for agriculture?

Would any positive feedback mechanisms be triggered?

How much would sea levels rise?

Something I’ve heard suggested is that, by slowing down the increase of CO2 in the air, and thus slowing down the increase in average ambient temperature, the best we can hope for is to slow down and delay the inevitable environmental catastrophe(s) that we are, eventually, doomed to suffer in any case.

Look at this map of state average temperatures:

> **[United States Yearly Annual Mean Daily Average Temperature Map](https://eldoradoweather.com/climate/US%20Climate%20Maps/Lower%2048%20States/Temperature/Mean%20Daily%20Average/us-annual-daily-average-temperature.html)**

> A Colored by Temperature Map of the United States with the Yearly Annual Mean Daily Average Temperatures for the US Lower 48 States.

Notice how each band of temperatures is about 5 degrees Fahrenheit which is roughly 3 degrees Celsius. So basically you would be living roughly comparable to what the climate is 200 to 300 miles south of you.

Interesting chart. So my location would be set to go from the temperature in Upstate South Carolina to…the temperature of a lower part of South Carolina.
