But no matter how fast we act, we are not going to “fix” the climate like a doctor fixes a broken leg. “The Earth’s climate is not a binary system or a switch that you can toggle on and off,” says Kate Marvel, a climate scientist at NASA’s Goddard Institute for Space Studies in New York.

The first report, released in 1990, was a weak sketch of the risks, from sea-level rise to drought to increased storm intensity. But it inspired the Earth Summit in Rio de Janeiro in 1992, where the issue of climate risk was addressed directly for the first time.
In 2010, the UNFCCC threw out the old metric of measuring progress by emissions reductions. Instead, they adopted a goal of stabilizing warming at less than 2 C , which quickly became known as the threshold for dangerous climate change. Where did the 2 C target come from? Think of it as a rough balance between what should be done and what can be done.
Even if we achieve the target of holding to 2 C, there will be unfathomable changes to our climate. In 2018, the IPCC published a special report that laid out the differences between a 2 C world and a 1.5 C world. “I was grumpy about the idea of the 1.5 report,” says NASA’s Kate Marvel. “I thought it was just fan fiction. But it had an unexpectedly galvanizing impact on people.” The report showed that, at 2 C, severe heat events would become 2.
The other big uncertainty about our climate future has to do with tipping points. The latest research is showing some Earth systems may be more resilient than most people thought. The Gulf Stream system, for example, “has been slowing down in recent decades,” says Gavin Schmidt, head of NASA’s Goddard Institute for Space Studies. “But I don’t think anyone is worried about it shutting down anytime soon.
The Rolling Stone doesn’t want the world to know of the lost civilizations hidden within the ice! coverup they want to keep the world in the dark ages. Man can adapt to anything, but a rolling stone gathers nothings new when it’s frozen!
I don't think that is up to us either. I mean the new bailout is wired to prop up Big Oil even though we know it is killing us.
