Please clap.
We now *know* what to do to stop climate change.
Project Drawdown has analyzed trillions of data points, spent tens of thousands of hours, and has done the hard work to find evidence-based solutions.
No more handwaving. No more greenwashing. Just science.
And we're giving it away for *free*.

The red line in (a) is the monthly mean with the seasonal variation removed; the blue dots and blue line in (a) depict the monthly averages. Observations from 179 stations were used for this analysis.
Holy wow, +3.5 ppm COβ last year, up from +2.4 ppm average the past decade, and +0.6 ppm in the 1960s.
It gets scarier the closer you look at it. All this is a stress test for the planet, and it's buckling.
Two big reasons for the massive increase: wildfires, and the ocean sinks are shutting down.
Reviewer #1: Thank you for your revised manuscript with thoughtful ideas.
Reviewer #2: I recommend against the publication of this study.
Reviewer#2 strikes again π
I am writing this because it has swiftly become crystal clear to me that many people have no idea what is happening or how this works. Here is a thread for non-academics to put into context what just happened to Dr. Mark Bray, a fellow historian.

A good time to remember that the economics prize was created by Swedish bankers in 1968 (67 years after the 5 original Nobel prizes) against the wishes of the Nobel family, partly to legitimize neoclassical economics in the public eye and partly to help banks avoid regulation.

Or maybe don't look up...
When we pitch, it's AI
When we hire, it's ML
When we implement, it's linear regression
Amazing work here highlighting the need for more demand side energy managent on the residential scale π congrats @kevinjkircher.com and team!!

"I have a foreboding of an America in my children's or grandchildren's time - when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness. -Carl Sagan (1934-1996) in his 1995 book The Demon-Haunted World: Science as a Candle in the Dark
