And yet, you do.
Why do you imagine the politicians would be concerned with climate change? It's not like they or the rest of the oligarchy are going to be the ones affected.
I think you could say the same about most issues that politicians (attempt to) address. Were Nixon or Nancy Reagan ever trapped in the inner-cities deciminated by the results of their failed drug policy? Were generations of their families imprisoned as a result? Does George Bush ever have to worry about ISIS causing harm to himself or his family? Or an onslaught of immigrants on his family ranch? Will Diane Fienstein be spending her old age alone, unarmed, 30 miles from her nearest neighbors or other assistance? Unlikely.
