Hello,

I'm working on an essay on global warming and the topic is - Runaway Global Warming: Fact or Fiction? . I've done my fair share of Googling and I'm more confused than ever before. ](*,) ](*,) How is global warming different from runaway global warming? Can someone please share some resources I can refer to?

Please help. :!:

Thanks!

The confusion comes from the various uses of the term "runaway". Some use it to indicate warming that cannot be controlled by humans with non-drastic measures. Others use it to indicate a warming that will continue until most if not all life on Earth is extinguished and we turn into something similar to Venus. The mechanisms are the same but the end point is the very significant difference.

The former is well underway, but the latter is not expected to occur due to the density of the Earth's atmosphere.

Thank you for shedding some light on it, Wayne. Makes sense.
It's a relief that runaway global warming is a theory. If it were to actually occur, our earth would become a massive microwave (after absorbing all radiation) and bake us all!

Thanks again :)

And yes, belated happy birthday! Have a fab year ahead. Cheers! :)

It is a little confusing since the warming will continue for a period even if we were to stop all emissions of formerly sequestered carbon. That is kind of a "runaway" situation since once we started it the process will continue until it peaks. The good news is, as you noted we will not turn into Venus and kill off all life on the planet. The bad news is that we might kill off a large portion of the life on the planet, including Homo sapiens.

It's inevitable, don't you think? I'm a big believer in Karma. Considering we have done so much damage to our planet, we should all be ready for repercussions.

I have been watching the progression, which is coming faster than expected for most. AT THIS TIME, the Arctic is losing 111 km3 of ice per month when it should be expanding. Reports from Alaskan fishermen of boiling seas as far as they can see, and the Siberian expedition that reported methane fountains by the hundreds in the 2011-14 expedition, to this fall up to over a km wide and by the thousands. The latest methane readings show a substantial increase from only the week before! I have read estimates of 2-5 GTs of methane self releases this year. Thousands to go.
It must be noted that the rise of each 1*C increases humidity by 7%. Thermal max is 200K thick white clouds with reflective albedo replacing their net GHG effect. along with exponential increase, eventually, of methane metabolizing bacteria. No Venus Effect is possible, IMEO. Thermal Max +13.2*C from pre-industrial, extinction rate 99%, recovery time 200K years with 5 million for surface life evolution. There is the possibility at this time of a Toba Effect large and long enough to stop the methane turnover process. Momentum must be accounted for, along with all the other environmental toxins and shut down without leaks of 400 nuclear reactors. This spring will be hot, then it will get worse. This is it, the rocket ride is at increasing G-force. We may have 4 years left in the Northern Hemisphere, another 1-3 years in the Southern. Latest calculation shows +6*C 2028.7, the point where surface life is extinct.
