Only a quarter of states have comprehensive heat acclimatization policies, Stearns said, which regulate rest periods, phasing in of equipment and numbers of training sessions a day. Only a quarter have polices requiring the use of wet-bulb globe temperature — considered the best way to measure heat stress since it includes ambient air temperature, humidity, direct sunlight and wind — to determine whether its too hot to practice.
Ah… I thought I’d been seeing more on Thwaites today…
The Florida Real Estate Board’s favourite group of researchers has a new article out. There’s not much new besides the “sound bite”, but a reminder nonetheless that this problem is still looming over us. Well, “over us” if you live in Florida …

The findings suggest Thwaites Glacier and much of the West Antarctic Ice Sheet could be lost by the 23rd century.
And we all know what happens when researchers report their more “conservative” findings so as not to be labelled “alarmist”.
However, there is also concern that additional processes revealed by recent studies, which are not yet well enough studied to be incorporated into large scale models, could cause retreat to accelerate sooner.
Yeah… time to dig into this, someone’s more upset than the headline suggests.
But the researchers also saw new patterns on the glacier base that raise questions. The base is not smooth, but there is a peak and valley ice-scape with plateaus and formations resembling sand dunes. The researchers hypothesize that these may have been formed by flowing water under the influence of Earth’s rotation.
The hypothesis of the origin aside, I’d guess that this means there’s more surface area, more than previously modelled, under there being melted by the “warm” sea water getting under there with the tides. That’s also going to change the model for how the glacier sticks to the bottom.
For decades, Midwestern farmers have devoted tens of millions of acres to just two crops, leaving the ground largely unprotected from wind and rain between harvest and planting. As a result, the loamy trove of topsoil that settlers found there has been pillaged. Using satellite imagery, a team of University of Massachusetts researchers has calculated that a third of the land in the present-day Corn Belt has completely lost its layer of carbon-rich soil
You can see how much soil has been lost across the corn belt by looking at old signposts. You can usually see a rough ring where the concrete that set the post in place was level with the original soil surface. This now sits proud of the ground by as much as a foot.
