A Progressive Leftist activist claims that global warming is his biggest concern yet the science article he cites is sorely lacking!!

 More Grim Climate Trends and Tipping Points

The climate crisis being the most important issue warrants even a deeper dive. Thanks for that Science article on the 1.5 degree "tipping points" yet I would scrutinize that science as well as being not well-educated. For example search the article for "methane" and you find something sorely lacking: We get this reference: D. Archer, B. Buffett, V. Brovkin, Ocean methane hydrates as a slow tipping point in the global carbon cycle. Proc. Natl. Acad. Sci. U.S.A.106, 20596–20601 (2009).

No - it's NOT a "slow tipping point" - it's a Methane Bomb of pressurized methane - over 500 gigatons that could easily blow very fast!!

So if we go read that reference cited in the article YOU cite - we find that methane hydrate article makes NO REFERENCE of Natalia Shakhova's research! Her research has been corroborated by an international research team as well - just a few years ago.

So there's no excuse for a "Science" article to ignore the East Siberian Arctic Shelf Methane bomb - the ESAS is the largest ocean shelf in the world!!

And some global climate models already put us at over 1.6 C global average - meaning these tipping points are already fully activated!!

Finally let's search the article you cite for the Aerosol Masking Effect...

No - Nothing! No mention of Dimming either. Yet recent science has proven the Aerosol Masking Effect is TWICE as bad as previously thought - this means a 40% decrease in sulfur pollution from burning coal (one third of CO2 emissions) will heat up Earth another 1 degree Celsius global average!! So that's a HUGE tipping point - in fact James Hansen of NASA global warming fame - he has stated that the Aerosol Masking Effect is the main cause of temperature increases now globally.
