1. “Introduce your idea in one picture”: Climate science and western policymakers still neglect bamboo, THE plant for resilience, climate adaptation and mitigation, because it can do it all. Worldwide use is a challenge, so start local. Can replace timber, plastic, concrete, edible, grow soil, etc.👇

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

« The marker that distinguishes Gen Z is how pessimistic its members are, and how much they feel like life is beyond their control, according to Jean Twenge, a psychologist who analyzed data from national surveys of high school students and first-year college students in her book “Generations.” »
Not only a game, it should be what you do at university. That it's not is the best explanation (really the only explanation) of climate change and the origins of it. 50 years of eyes-open depredation.

As I wrote earlier, the nice thing about large heat pumps is that it's a bit like the Olympics: there are lots of medals to be won in different categories. Is this the largest heat pump in the world? In this class (input: river, output: steam), perhaps yes.
One of the world’s largest industrial heat pumps is coming to Boston.
A 35MW system will use energy from the Charles River and deliver steam to heat more than 70 million square feet of buildings across Boston and Cambridge — hospitals, schools, homes, and businesses alike.

NOAA did not post a CO2 average for September, 2025. Based on all of the available data, CO2 averaged 424.41 ppm for Sept., 2025, a gain of 2.38 ppm from Sept., 2024.
The mean rate of CO2 growth (ppm growth per 3 years) is near an all-time high.
