Would Slowing Earth Temperature Rise Matter More than Stopping it?
What to Make of 485 Million Years of Temperature History
๐๐๐๐ฉ ๐๐๐ช๐๐๐ฉ ๐ข๐ฎ ๐๐ฉ๐ฉ๐๐ฃ๐ฉ๐๐ค๐ฃ? Research from Emily Judd highlighted in the Washington Post concluding that earthโs average temperature is warming at a historically rapid rate (vs the last 485 million years), but from a very low base (earth has typically been much warmer,20C+ at times, over the last half billion years).
๐๐๐ฎ ๐๐ฉ ๐ข๐๐ฉ๐ฉ๐๐ง๐จ? The study provides context for the earthโs warming trend, and the implications of high temperatures and rapid warming. Human history extends through a cold period in earthโs multibillion year experience, and warming baselines typically go back only a couple hundred years. Warming a few degrees keeps the planet well within historical range, but rapid temperature change (also a feature of recent decades) has proven traumatic for life.
Iโm left with a host of questions:
Will the lower baseline enable life to be more resilient if the worst warming models prove accurate?
Will the high rate of change change persist?
Could slowing the rate of change prove more important than arresting warming all together?
