Average CO2 levels throughout earth's history
Cambrian 5800 PPM
Ordovician 4300 PPM
Silurian 3800 PPM
Devonian 3200 PPM
Carboniferous 380 PPM same as today
Permian 1200 PPM
Triassic 1400 PPM
Jurassic 2000 PPM
Cretaceous 1200 PPM
Tertiary 800 PPM
Currently today 385 PPM
The average temps throughout earth's history was very constant roughly 25 degrees Centigrade.

CO2 supports your life, and follows the natrual weather changes.

CO2 supports your life, and FOLLOWS plant growth cycles. They take in all the cO2 we can give them. More CO2, more life on Earth.

Nuclear power kills life. CO2 supports all life. So nuclear power kills, fossil feuls support more! Go think about! Nuclear is NOT nice. GW is their PR, designed to kill YOU

Actually fossile fuels kill the atmosphere. Nuclear power plants only give out steam from the cooling towers while those fossile fuel burning powerplants give out smoke n all that sh1t.. Ok the waste that's produced is a bit deadly lol but it's not like they ferry it to your own bedroom is it? It's taken several hundred meters below ground and if you take some readings on the surface you'll notice that it's not super radioactive there...

Plants take in the 0.00037% CO2 in the air to support life on Earth: Nuclear power is good at killing life!

The world is cooling.

'Global WArming' was ficiton from nuclear power, put about by stooges. Are you thick, or were you paid?
