Global warming could be far worse than predicted, new study suggests

Collapsing polar ice caps, a green Sahara Desert, a 20-foot sea-level rise.

That's the potential future of Earth, a new study suggests, noting that global warming could be twice as warm as current climate models predict.

The rate of warming is also remarkable: “The changes we see today are much faster than anything encountered in Earth’s history. In terms of rate of change, we are in uncharted waters,” said study co-author Katrin Meissner of the University of New South Wales in Australia.

This could mean the landmark Paris Climate Agreement – which seeks to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels – may not be enough to ward off catastrophe.

1. Current CO2 levels are higher than the last time there was a +2

degree anomaly. It makes sense that the current anomaly would stabilize higher than that, everything else being equal.

2. It is going to be much.

Worse than the projections. Simply look at a graph of CO2 vs Temp over the last few hundred thousand years. The two track uniformly for entire duration except for the last hundred or so years where CO2 goes clear off the chart. The temp will eventually catch up, it will be well over the 2C threshold and this planet is going to change in ways we have not even considered.

3. And hard to predict if a catastrophic failure will rapidly kick in.

There are few warning signs for a system as whole.

4. Kicked and recommended.

Thanks for the thread Snellius

5. "Far worse than predicted" has been the mantra for some years now.

since measuring what happened is more accurate than measuring what could happen.
I just assume it will always be worse.
