--- Quote from: tom66 on August 07, 2023, 09:33:09 pm ---The fear is now as the climate warms we could see permafrost (such as the large plains in Siberia) start to melt which often releases trapped methane gas. This could cause further warming and further releases and it doesn't matter how much in CO2 emissions we abate, the methane has a far more significant impact. --- End quote --- To put this into electrical engineering terms, this is a type of positive feedback. There are probably plenty of similar mechanisms that we don't know about yet that could cause even more warming and more detrimental change. |

--- Quote ---There are probably plenty of similar mechanisms that we don't know about yet that could cause even more warming and more detrimental change. --- End quote --- Fear mongering about "mechanisms that we don't know". Let me rephrase this in another way There are probably plenty of opposite mechanisms that we don't know about yet that could cause less warming/possible cooling and slow down/reverse change. We then would fear the demise of the human race via cooling instead of warming. |

We know of human aerosol emissions slightly cooling the climate, but what else is there? Methane permafrost is understood, the problem is, we have no way to accurately measure how much methane the permafrost contains. It varies in concentration depending on the age of the marsh and the type of plant matter that is built up there. Estimates range from equivalent 15% of human CO2 emissions to up to 50%, and the rate at which such gas could be released also varies, from most released by 2050 to most released by 2100. |
