Global warming is normal. The Earth heats and cools over millions of years, like it is heating now.
It is normal because studies show that in prehistoric times the North pole was inhabited by fish that depend and only swim in warm water. Plus they studied the trapped air in the ice that was frozen, it also tells a partial history of what happened.
Once this happens the Sahara desert will reach Europe, then settles back as the ice age slowly looms over the planet.
Its part of nature.
