NASA has a bunch of stunning images online showing what a ~1 degree Celsius warming over the last century has done to the planet.
Click on the image above for many, many more images. What’s even more amazing to me is the number of people who still believe the planet is not warming, or that this is all a natural cycle. Every possible internal cycle has been looked at. Even if a new one was discovered, the amount of heat trapping from greenhouse gases is known and understood all the way down to a sub-atomic level.
