Reply to comment by clampie in Greenland's glaciers are melting 100 times faster than estimated by strangeattractors

Documentaries I have seen say the old models didn’t include everything they are seeing today.. there are lots of positive feedback loops created that either couldnt be included in modeling or they just didn’t know to include.

Something like all the methane gas released from melting permafrost, which accelerates climate change, which accelerates climate change…etc.

Old model rendered completely too conservative.

Then why climate sensitivity(how much the world is expected to warm if CO2 levels double compared to pre-industrial levels) estimates haven't changed for the past 40 years?
