Climate Change This Week: Warmer Then, Not Now
Another study shows that global warming isn’t new or man-made.
A new study from Swedish climate scientists indicates that the earth was likely warmer during the ancient Roman empire and Medieval period than it is today. Leif Kullman, the study’s author, found that tree lines were at higher elevation during those times than they are today, mainly because “summer temperatures during the early Holocene thermal optimum [Roman and Medieval period] may have been 2.3°C higher than present.” Something tells us that wasn’t because of all the Roman SUVs.
Certainly, one report doesn’t prove anything one way or the other, but the trend is certainly not going in favor of those who want to blame “global warming” on modern human activity and then clamp down on it with draconian government measures. Despite the alarmism today, temperatures have not increased globally since 1998, leaving warmists scrambling to come up with an explanation. Indeed, just last week saw 2,000 cold and snow records broken in the U.S.
In light of this mounting evidence, some climate scientists are – gasp – becoming skeptics. Judith Curry, a climatologist at the Georgia Institute of Technology, says, “All other things being equal, adding more greenhouse gases to the atmosphere will have a warming effect on the planet. However, all things are never equal, and what we are seeing is natural climate variability dominating over human impact.” That’s worth repeating: Natural climate variability might have something to do with the climate.
