The rapid warming of Svalbard is triggering a positive feedback loop

When glaciers melt, groundwater springs gush forth through the newly-exposed ground. Even during winter, groundwater springs leak out near the edge of glaciers. When groundwater is exposed to surface temperatures, it rapidly freezes. The resulting ice fields can stretch for kilometers, running several meters thick.

Beneath these glaciers and permafrost, lie colossal deposits of the harmful greenhouse gas, methane. Researchers believe that methane escape might be accelerating warming in this part of the world. To test this theory, Gabrielle Kleber, of the University of Cambridge, in the U.K., and colleagues explored the potential seepage of methane from groundwater springs near melting glaciers.

To collect samples of groundwater, Kleber and colleagues drilled deep into these fields of ice, until they hit the pressurized springs. “We were surprised to find just how much methane was present in these groundwater springs,” Kleber told Advanced Science News. “In fact, sometimes when we’d drill into the ice, we’d find that a lot of very pressurized gas was released before the water. This gas could be ignited, meaning that it was mostly methane.”

1. Yep...

...it's a domino effect.

Our ecology is an extremely complex system with all of it's components (microsystems) entirely dependent on and inyeracting with each other.

A change (or damage) to one component will have effects on the multitude of other components it interacts with, and those components will do the same with others that they interact with.

We've known this would be the overall affect of CO2 emissions for decades.

3. We've know this from the geologic record too

The system will tip over just over a dozen years. The multi trillion question is how far into those dozen we are already.

2. our only hope is a mega volcano.

4. Yep

Of course that will bring its own chaos and collapse, but that is our biggest hope. I've been hoping for a global artificial snowmaking with all the military ships to nudge the Earth's albedo up to be more reflective.

5. If we try...

...ANYTHING 'geo-engineered', it must be something we could immediately reverse if it starts to cause any unexpected effects that could just make it all worse.
