Risk analysis now needed of relative vulnerability of these forest age groups to climate-related and other stresses, as noted by authors (e.g. Anderegg, W. R. L., et al. (2022). A climate risk analysis of Earth’s forests in the 21st century. Science, 377(6610), 1099–1103. doi.org/10.1126/scie... )

Climate change is predicted to change forest composition, decrease carbon, and increase disturbance, with some forests at high risk of all three.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

After a 6 week review we are officially cancelling 83% of the programs at USAID.
The 5200 contracts that are now cancelled spent tens of billions of dollars in ways that did not serve, (and in some cases even harmed), the core national interests of the United States.
In consultation with Congress, we intend for the remaining 18% of programs we are keeping (approximately 1000) to now be administered more effectively under the State Department.
Thank you to DOGE and our hardworking staff who worked very long hours to achieve this overdue and historic reform.

So to make Bluesky (or Mastodon) work, it seems to me that we need to get back to the sustained dialog on substantive points that was Birdtalk at its best. But it seems to me that this requires us to engage on a few posts, rather than just using it for our own talking points. What am I missing?

Note: A scientifically solid & practically useful literature on "tipping points" in local nature-society systems has been available since at least the early 1960s: Ricker (1963) "Big Effects from Small Causes" in fisheries management, Holling (1973) "Resilience & stability of ecological systems."

William Clark (william_clark@hks.harvard.edu) @wclark.bsky.social · 03/12/2024
This critique of "tipping point" framings in discussions of climate action applies even more strongly to its use in the context of other (i.e. non-climate) planetary boundaries where appreciation of spatial heterogeneity & context dependence are transcendently important for effective policy design.
