Yesterday, we had a webinar organised by the #PEPR #FORESTT on the use of species distribution models #SDMs with application in forestry 🌳🌲 You can watch 📹 16 talks on this topic, including one on the impacts of microclimatic processes for species (re)distribution ⬇️

Hopefully, this database disambiguates some of the different ways to measure (and interpret) PHTs. Look at panel A in the figure below - 70 distinct methods even after trying to simplify and categorize them.

Plant heat tolerances (PHTs) remain a hot topic (pun intended), but their physiological relevance to broader metrics of performance - and even other metrics of heat tolerance - are are poorly established. Part of the issue with plant heat tolerances is that they are measured so many different ways.

Where are all the posts about new papers that have been published? I left Twitter/X, but haven’t been able to recapture the same utility here.

For better or worse, most of the science I see posted is in LinkedIn. LinkedIn!!!

The National Climate Assessment, and all special reports and past assessments, are now offline. Federal climate science is being systematically erased.

That said, supporting a political party that seems inherently anti-science does seem hare brained.

I think this is a fascinating interview. 38:11 when Thiel takes a long time to answer if he thinks humans should persist is astonishing - not far off from closing the circle with radical environmentalists.

I agree that there has been stagnation from my narrow perspective on science.

Wow- this is a fascinating interview. & unhinged towards the end. Curious what other people think, esp about the stagnation of science.

A scientist once told me that science was just finding new ways to test the same hypothesis, which sounds like stagnation to me.

I’m very excited to have led the scientific efforts along with the many moving parts overlooked by other team members that made this happen.

It feels amazing to put years of experience and education to work restoring degraded lands and mitigating climate change

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.

@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!
