Skeptical Science New Research for Week #41, 2019

38 articles, 9 open access

Known unknowns become known

3 months of SkS research news exposes a persistent feature of the weekly harvest: reports of investigations of expected climate outcomes in particular geographical sectors of Earth. This is made possible by regional climate modeling, a capacity that has matured and almost equally importantly become less expensive and hence more widely available in recent years. Earlier this year Filippo Giorgi's Thirty Years of Regional Climate Modeling: Where Are We and Where Are We Going next? (open access) comprehensively described how we've arrived at the point that we may project our likely experience decades into the future.This ability allows us to tackle both mitigation of and adaptation to global warming in a plethora of modes, not least in agriculture, engineering and health sciences. We have a lot of planning to do if we're to optimize the dilemma we've created but happily we've developed the skill and resources to drive this planning with numbers.

We knew something was going to happen but now increasingly we can say how much and where. That tells us what we need to do.

More generally, it's one thing to hear that the world's temperature will increase by 2 degrees centigrade if we play our remaining cards exactly right, but our imaginations may light up a little more brightly when "2 degrees" is replaced by "these things will happen" and  "world" is replaced by "on my continent," or "in my country's borders" or "in my province" or "in my county." This information invites comparisons and comparisons can lead to resentment. The Earth being spherical and hence a closed space, as a pragmatic matter we're all in this together despite regional disparities; each local choice counts to a whole that we must each wish to be successful. Hopefully regional climate modeling will translate into public awareness and motivation that finds a sink in wise formulation of public policy connecting dots in a bigger picture.
