So they want compensation for global warming? Well I say we let them sue the sun, we'll see how much money they get. Yes, the planet does get hotter and colder all on it's own, believe it or not. Remember ice ages, and global cooling scares from the 1970's, and that the mean temperature during the Jurassic age was 3 degrees C higher than it is today. Correlation does not equal causation. Interesting how in all the graphs about global warming which compare temperature with CO2 levels, the temperature always raises before the CO2. The Earth changes, the sun changes, and the trees you planted in your backyard to help combat global warming? They're killing you.
