1. Vast amounts of forests that acted as a heat sink have been clear cut creating higher surface temperatures.

2. Reducing emissions have lead to less cloud cover further increasing surface temperatures.

3. Natural climate cycles caused by solar and terrestrial factors also create periods of higher surface temperatures adding to the heat.

To reduce "global warming":

1. Plant trees and vegetation.

2. Emit more "smog".

3. Nothing. You can't change nature.

Just DON'T stop oil!
