I`ve been saying this for years! the sun is warmer... it flutuates in heartt out put, always has always will....no matter how many fossil fuels we burn.... But of course I dont have the clout as others do....I didnt even invent the internet!
the Martian polar cap getting smaller is NOT because of our Rovers! .....
actually our current "dirt in the atmosphere" HELPS us , it screens some of the sunlight out , if we didnt have it ,it would be EVEN WARMER!
