ohhh my there is a delay ... the earth is a complex place if it reacted in an instance we would not be here
tell you what tell me in 5-10 yrs that the earth is overheating ..
that is if your still here we are in a cooling faze(at least the next 40 yrs) mix that with a polar flip or even a wobble and guess what happens .. at least a 1/3 of the planet go's to sleep
at worst another ice age . if not we will start to warm again and be fine for the next 1000 yrs
we are well over due for many things ..
