History/ permafrost/antarctic core samples etc reflect 400ppm of atmospheric carbon (co2 methane etc ) as the point at which the planet has experienced massive climate shifts.


Currently our atmosphere is running at about 385 ppm ( atmospheric warming) and we are also in a solar warming phase as well

Thats about a 38% atmosheric carbon rise since the start of industrialisation (or over 100ppm in not even a micro second of the cosmic clock).......and rising at record rates....compounded by a hotter sun phase

Considered irreversible around 400ppm...and we have left it to out elected governments to untangle....
