Tap water is regulated, bottled water is not. But I guess under Trump environmental regs are more of a Wild West.

We had a good time sledding in it. At least it wasn’t too cold.

Seems like based on that paper on GWP and atmospheric chemistry, methane *emissions* are responsible for roughly one-third of warming, yes?

@climateofgavin.bsky.social or @benpoulter.bsky.social any chance you could help explain some of this? "Observed warming" versus "warming attributed" to GHGs or all agents is tripping me up.

Seems like ~1/3 & ~1/2 are both true, depending on what you're comparing to. Methane [is] responsible for ~47% of total obs. warming (1.07 degC); in comparison with the warming attributable to all well-mixed GHGs (~34%); and the temp. increase due to all warming agents (incl. aeresols etc) (~28%).

Good point, Annie. Thanks for pointing this nuance about warming attributed to methane. I'll look into this article and consult with our science team.

Thank you, Annie. Yes, the numbers in this article and the figure came from that Global Methane Budget (published in 2025), the UN FAO (for biomass burning methane attributed to the food system), and in consultation with one of the authors of the Global Methane Budget.

Love that meme, Rich 😆
