Many scientists now say global warming could stop relatively quickly after emissions go to zero
Parts of the world economy may have been on pause during 2020, dampening greenhouse gas emissions for a while. But that didn’t slow the overall buildup of atmospheric carbon dioxide, which reached its highest level in millions of years. If anything, research during the year showed global warming is accelerating…As polar ice melts more quickly, sea level rise also accelerates…The acceleration could be felt especially strongly along the West Coast, where sea level is starting to rise much faster than in recent years, according to NASA.
