Global warming can stress plants and soils — proved

They can take up to two years to recover from an extremely hot summer.

Well, with global warming, we’re going to have ever-more extremely hot summers, compared to the baseline for plants and soils.

Plots of soil from the breadbasket, central Oklahoma, were tested, subject to a 7-degree rise in the second of two years of study.

Researcher Jay Arnone said the increase was based on between eight and 11 exceptionally warm years in the weather records, spanning from 1873 to 1999, where the plots had been dug up. These warm years were between 1.0 and 3.8 C (1.8 and 6.9 F) higher than the region's long-term average, but were not accompanied by drought.

So, his test was at the high end of high-temperature historic years, but not anomalous, as global warming deniers are surely already claiming.
