Evolving nature-based solutions for urban resilience
Despite growing investments in nature-based solutions for urban resilience, their design often overlooks a fundamental biological process: evolution. Populations of organisms that sustain nature-based...

Here's an excerpt:
The COP30 global climate summit in Brazil may have been the last opportunity for the nations of the world to reach an agreement that limits planetary warming below catastrophic (>1.5C/3F) levels. By that criterion alone, the now-completed COP30 conference was an abject failure, despite whatever other progress might be claimed. In my recent book “Science Under Siege” with public health scientist Peter Hotez, we discuss the five main forces that threaten the planet. One of them is billionaire plutocrats like Bill Gates, who sidetracked the conversation going into COP30 by dismissing the urgency of climate mitigation. But an even greater threat is bad actor petrostates like Russia, Saudi Arabia, and now—under current Republican rule—the United States. They have banded together to weaponize the “consensus” rule machinery of the UNFCCC, hijacking the negotiations and blocking any meaningful commitment or timeline for phasing out fossil fuels. Both the patience of most serious climate advocates—and the clock—are quickly now running out.

As if it wasn’t clear already, fundamental changes must now be made in the UNFCCC rules. A small number of rogue nations cannot be allowed to block progress for the rest of the world. One suggestion has been a rule change requiring a three-fourths (75%) rather than a “consensus” of all countries for reaching an agreement. The cruel irony here, however, is that such a rule change would also require “consensus” among participating nations.

This is the best messaging I’ve seen from any Democrats on the shutdown. Kudos to AOC, Bernie, and their teams for putting this out there.

I would just like to say: I don't want to see his face or listen to his voice. I don't want to see the xeets or late-night rantings. Unless it's a policy, don't share it. Don't give it any more attention than is absolutely necessary.

Shockingly few people are talking about the toxic air and water in LA. It’s eerily reminiscent of early days of the pandemic when we were assured we didn’t have to mask Listen to air quality experts. The same folk educating about IAQ & COVID are providing life saving info now. And wear a mask.
