    The predictions were always the most conservative estimates. They were trying to avoid panic. The most likely scenario was that this would all start and hit hard within our lifetimes.

      Exactly right. The feedback loops aren’t even accounted for in the results we are given. Namely the methane and co2 from the permafrost. There is enough just in that feedback in just the siberian permafrost to cause runaway warming, 2x the carbon as currently in the atmosphere, freed by bacteria working in above freezing temperatures. The methane is massive idk the estimates on that, but to date methane is estimated to be about 30% of warming. Swamps basically, huge methane sinks that have been stoppered up for thousands of years brewing those hyrdocarbons underground.

      And the arctic is warming at like 6x the rest of the world last I heard.
