There are a small number of people on both sides who are obsessed. One side has the idea that global warming is a catastrophe. The other believes that manmade warming is 100% fake. They are both wrong, but they add a huge amount of noise to the comment sections and make it look like lots of people care.
But really almost nobody cares, even liberals don't care except for their usual caring about issues that can be weaponized like "ripping children from the their parents". Liberals certainly don't care about children.
Manmade warming IS 100% fake. Man is a ‘fart in a windstorm’.
