We are at about 400ppm of CO2 up from around 350ppm so an increase of 50ppm.
I am not going to look up for the exact stats but....if I remember correctly, the first 20ppm of CO2 will absorb about 80% in heat of what CO2 would absorb at even higher saturated levels.
So anything above 20ppm would only have the potential of absorbing 20% more heat no matter how much more CO2 is added.
Additionally, we are at a historic low of CO2 and plants begin to die off at around 150-180ppm and lower.
Let me just add..... I hate Libtrads.
Exactly correct. At present we are far below CO2 levels for maximum growth of plants. We are far closer to extinction levels (it has happened in the past) than maximum life on earth. CO2 is plant food and the oceans may rise and it does not have one damn thing to do with man. It is a function of the sun and orbital mechanics.
When the earth is cold glaciers kill life. When the earth is warm life flourishes and the sea levels do change over thousands of years and we retreat over thousands of years from the sea as we did in the past and are doing so today. Pray "global warming" continues as we will prosper.
Geological history tells us this most prosperous time of "inter glacial warming is brief" and we will soon descend into full glacial and life will perish. By definition we are still in an ice age as the polar caps have not melted. This has happened many times in the past.
I hope this is not just an inter glacial warming period and a true end to an ice age. It probably is not. Yes the seas will rise and life on earth will flourish as we slowly recede from the rising shore lines. Otherwise it is back to full glacial and life perishes.
