I use it & curse its poor search, awkward formatting; terrible selection capabilites ; & frustrating cut & paste. AAAAARRRGH.

It's largely unusable. But it's all I've got..... le sigh.

We bring climate science into disrepute by not acknowledging the parts that we don't yet firmly know. So let's not do that, please. (◕‿◕✿)

This "cows killed the Sahara" is still a theory that remains unproven; other reputable climate scientists do not yet agree. We have to be honest about that & separate settled science from the unsettled. Otherwise we only induce doubt in the settled science.

"It’s important to note that the green Sahara always would’ve turned back into a desert even without humans doing anything—that’s just how Earth’s orbit works, says geologist Jessica Tierney, an associate professor of geoscience at the University of Arizona.

Moreover, according to Tierney, we don’t necessarily need humans to explain the abruptness of the transition from green to desert.

Instead, the culprits might be regular old vegetation feedbacks and changes in the amount of dust. “At first you have this slow change in the Earth’s orbit,” Tierney explains. “As that’s happening, the West African monsoon is going to get a little bit weaker. Slowly you’ll degrade the landscape, switching from desert to vegetation. And then at some point you pass the tipping point where change accelerates.”

We just need a lot more research on this point. And I say this as a strong climate activist, not as a denier or delayer.

Best wishes!

As someone who's lived in Germany for the last 7 years & come to the UK this semester, please let me inform you that hell will freeze over before Germans want you back. They've moved on from what they now perceive to have been a toxic & unreliable relationship.

Sorry. Maybe they'll mellow in the 2030s. (◕‿◕✿)

This is certainly useful but not quickly actionable. While testing incoming travelers maybe only reduces spread by 10%, that could be a meaningful number if your health system is falling over, as appears to be happening in some regions now.
