Earth has generably been warming for the past 22,025 years (+5 degrees Celsius), but about 1 degree of that was in the past 40 years. Are human activities causing climate change?
9.8 up - 5.5 down = 4.3 gigatonnes of carbon per year extra from fossil fuel & cement
That image lacks methane from melting Siberian permafrost (Just top that up? Helsinki's 2010-2011 snow mountain lasted the hot summer of 2014. Maybe bring back the Ice King or do some ground refrigeration like at Fukushima.), but fortunately smoke from wars and cars appears to reflect sunlight before the rest of Earth soaks it up. Maybe burnt sacrifices (being carbon neutral if using recently grown wood) weren't so bad after all compared to the Sun cooking us.
