@btschumy I was a reviewer of the MRV chapter and it’s good. It’s a lot of effort to put something like this together and I’m glad someone is doing it.

Fossil fuels have gotten us where we are today (both positive and negative), and we should use them to build up our renewable infrastructure so that we never need them again.

Congrats to Claudia Sheinbaum and Mexico! 🥳

The US also has some great women climate scientists. Just sayin'.

Serious question: Why is it that bicycle commuters in Paris are in super stylish street clothes, whereas the ones in London dress like they're in the Tour de France?

Many people have been on the Piccadilly line to Cockfosters but how many people have actually been to Cockfosters?

The IPCC says* it’s unequivocal that humans are responsible for global heating and our GHG emissions are responsible for 100% of the recent warming.

Preindustrial atmospheric CO₂ was ~280 ppm and now it’s >420 ppm, so we’re responsible for 33% of what’s in the atmosphere (not 3%).

*When I say “the IPCC says…”, that’s shorthand for “some of the world’s best scientists volunteered years of their time pouring over tons of peer reviewed publications and summarized their conclusions to say…”.

It’s so crazy that climate deniers think humans don’t cause climate change but volcanic eruptions do.

The eruption of Mount St. Helens released ~10 Mt of CO₂ into the atmosphere.

Human activities currently release that amount of CO₂ in ~2 hours.

In talking about the shortcomings of carbon capture and storage , we talk a lot about the failures of capture and not enough about the failures of storage.

It’s pretty funny that if you say “orange man baby” everyone knows who you’re talking about.

"The market for carbon offsets shrank dramatically last year, falling from $1.9bn (£1.5bn) in 2022 to $723m in 2023, a new report has found. The drop came after a series of scientific and media reports found many offsetting schemes do nothing to mitigate the climate crisis…"

I'm shocked! Shocked to find that "[s]ome of the world’s most profitable – and most polluting corporations – have invested in carbon offset projects that have fundamental failings and are 'probably junk'"

As long as we keep using fossil fuels, we’re going to keep contaminating our drinking water with hydrocarbons.

Any carbon dioxide removal (CDR) method that draws in a lot of air or water — like direct air capture or direct ocean removal — should consider the ecosystem consequences of drawing in a lot of insects, microbes, small animals, plankton, invertebrate larvae, and fish larvae, etc.

Only in a world that has no intention of decarbonizing does this make sense.
