To stop global warming we must quit burning fossil fuels for energy and switch to renewable energy. Unfortunately, the more warming that occurs makes it more difficult to switch to renewable energy. Here are some of the reasons:

We need to switch to renewable energy quickly before it gets more difficult to do so. Here is an interesting study that shows that renewable energy is less expensive than fossil-fuels energy in the European Union when all hidden costs are included:
