Ethanol, made from corn for transportation use, makes food prices go up. Higher corn prices mean higher costs for eggs, chickens, pork, and beef. Not allowing drilling on government land and offshore causes gasoline prices to go up because we now have to import oil to make gasoline and diesel fuel.
The poles are shifting, north magnetic pole is now going towards Siberia. This can cause "climate change". The poles shifted about 10,000 years ago, causing the ice age to end, thus global warming. There are more earthquakes when the sun goes through solar minimum and maximum.
But No, the Democrats and Globalists say it is man made global warming.
