7.5.7 Processes Underlying Uncertainty in the Global Temperature Response to Forcing

There is robust evidence and high agreement across a diverse range of modelling approaches and thus high confidence that radiative feedbacks are the largest source of uncertainty in projected global warming out to 2100 under increasing or stable emissions scenarios, and that cloud feedbacks in particular are the dominant source of that uncertainty. Uncertainty in radiative forcing plays an important but generally secondary role. Uncertainty in global ocean heat uptake plays a lesser role in global warming uncertainty, but ocean circulation could play an important role through its effect on sea surface warming patterns which in turn project onto radiative feedbacks through the pattern effect (Section 7.4.4.3).

On post-2100 time scales carbon cycle uncertainty such as that related to permafrost thawing could become increasingly important, especially under high-emissions scenarios (Figure 5.30).

This graph shows how far models are in la la land now if compared to observed developments

Ocean heat uptake drives now the surface warming via marine heatwave expansion and El Nino frequency and warming jumps, while new emission estimates from permafrost thaw till 2100 are now in runaway territory

And then bring down GHG levels as fast as we can do it as at current GHG levels oceans will continue to take up more heat - cloud feedback likely continues driving ocean heat uptake

This has to be stopped with SRM via the stratosphere which is high risk - but what else there is?

Fun fact Zeke Hausfather posted a Modell result going off charts in terms of El Nino strength - think it still a bit early but for sure this system has now lots of potential and it will strike again massively. If it happens in 2026/27 we would have to react directly with all we've got or that's it

But also maybe more likely we will see now a weakening signal to emerge from natural variability

Interesting subsurface freshening at some hundred meters deep strengthened deep convection in the irminger sea and Labrador sea - but changed now again

But all way more complex than models can simulate

Absolutely - currently I bet first a strengthening signal transporting more heat north producing more melt water which then leads to a shut down - a positive NAO we have, a strengthening inverse energy cascade to larger scales, stronger and more winter storms and summer sea ice loss Arctic Ocean

Some deep convection sites of the AMOC weaken while others strengthen - question is in how far this represents a more stable or a weaker AMOC?

All open till now

Anyhow the whole Earth system is now collapsing and that is the real story from which the AMOC collapse noise is distracting

Will be interesting in how far the heat, drought, and wildfire feedback will evolve if we get a serious El Nino event

Important: the strength of temperature jumps during El Nino depends increasingly on other feedbacks that synchronize during these events
