How do we deal with 10-12 feet of global sea level rise nearly instantaneously? There is a single glacier called in an Antarctica called Thwaites which is also known as the "cork" on an Antarctic sea that, if it melts or comes unstuck, could cause that much sea level rise that quickly.
"Thwaites is like a cork in a wine bottle—when it melts, it could trigger the collapse of a large portion of West Antarctica, equal to roughly 11 feet of global sea rise."
...
"Winds are now pushing a layer of warm ocean water up underneath part of the glacier that extends out into the sea and melting it, faster and faster. If that part breaks off, the entire glacier would destabilize."
We do have economies B for controlled experiments and that data is pretty clear.
The richest countries are those who use the most energy to help them deal with nature.
Effects might happen depending on the temperature but we don't know which or how severe or when or if it will. We don't know how much humans affect it meaning that we don't know if it even make sense to do anything.
Evolution is not scientifically demonstrated. It's a way to interpret the data and observations from biology. It's the model that explains the best, but it's not in itself science just like climate science isn't science in any concise way but rather an interpretation of data.
It's that data which is being discussed and speculated about. We are very far from demonstrating even a fraction of what we speculate.
