Finally we again have a President and an administration that is going to try to save humanity. Biden said “If it isn’t too late to save us from the worst effect of climate change…”. His question is critical to life on Earth/
The projections worrying him are for the conditions in 2100 without considering what conditions will be in 2150 or 2200 is like the analogy of someone falling off a building and saying “so far, so good” with each floor. The question for us is how high the building is. Is it one floor and we can limp away, or two floors and we can crawl away with a few broken bones, or maybe three floors with too many broken bones to move, or four floors with a cracked skull and internal injuries? Projections for 2100 are for four floors of damage. Beyond 2100 is like falling off the fifth floor to splat on the pavement.
Biden is right in the question. We are already experiencing long term droughts broken by a heavy rain or two before resuming, greater numbers of storms and hurricanes, warmer winters, and flora and fauna moving farther north. Glaciers around the world are melting. The seas are rising and flooding of cities is already happening. His question is this. Is it like a two or three story building, or are we just passing the top floor of a skyscraper saying “so far, so good.”
