Expect financial fallout when the fossil fuel bubble finally bursts | The Hill

Largely as a result, the world is on track for 2.5 to 2.9 degrees Celsius of warming (4.5 to 5.2 degrees Fahrenheit) — well past the 1.5 degrees Celsius (2.7 degrees Fahrenheit) guardrail. That’s the level at which warming will push the planet past self-reinforcing feedback loops and into tipping points with irreversible and catastrophic effects, which are projected to ultimately alter the climate so significantly it may no longer be habitable for life on Earth — including humans. There are signs this is already starting to happen.

The ongoing delay in a necessary transition away from fossil fuels means actions now must be accelerated. If we are to have a chance of staying relatively safe, fossil fuel emissions will have to be slashed by 43 percent by 2030 — threatening to strand significant investments. It also means that, if we are to have a chance of staying within sight of the 1.5 degrees Celsius guardrail, the fossil fuel industry must invest 50 percent of its annual capital expenditure in clean energy. Today, it invests an anemic 2.5 percent, while continuing to fund further exploration.

That sounds scary, therefore I believe it won't / can't happen.

According to the National Oceanic Atmospheric Association (NOAA), there’s now a 60% chance La Niña will develop between June and August and an 85% chance it's in effect by November 2024 to January 2025.

I hope it doesn't develop earlier than November.

I think such hysterical hyperbole does a disservice to his own cause.  I doubt anyone is really predicting this as a possibility even centuries from now.

may no longer be habitable for life on Earth — including humans.

People don't like worst case scenarios, so they don't talk about them very much. They don't even like to imagine them lest that make the face the fact that they're possible.

In truth, I kinda agree with you. I don't think that global warming, even if we hit some of the possible tipping points where positive feedbacks accelerate warming well beyond what just our CO2/methane releases do, will render the planet completely inhabitable to human life. Maybe the tropics will be so hot as to be uninhabitable, but that probably will make Nova Scotia a pretty nice place to live. 

For me it's more about what happens if we destabilize the climate and ecosystem, and thus food chain / agriculture, such that the planet can no longer feed 8B+ humans, and that number is cut in half or worse within the span of a generation. 

Because "habitable" can be a lot of things. We may still have a habitable planet but one that cannot support a modern technological society. 

That, I think is possible.

Not if the Gulf Stream collapses.

He said for all life, including humans. I don’t think that possible short of the Sun going nova.

Fair enough. I'd say that was an overreach on his part.

We used to see rogue waves on Lake Michigan. We had 3-4 foot seas and then all of a sudden, a 10 footer showed up. That rocked the boat.
