'Weathered' on PBS Terra asks 'Has Earth Already Crossed MAJOR Tipping Points?'

I examined the AMOC (Atlantic Meridional Overturning Circulation), one of Earth's tipping points yesterday. I concluded that examination by telling my readers "I have one more climate change video to share. Stay tuned to see if I use it tomorrow before I go full holiday for Thanksgiving." I'm sharing it, so watch as Weathered: Earth's Extremes on PBS Terra asks Has Earth Already Crossed MAJOR Tipping Points?

The Weathered crew traveled all over the US and abroad to answer pressing questions about our changing climate in our new series, Weathered, Earth's Extremes. Maiya and the team worked so hard on this show -- we can't wait for you to watch it!

Maiya May is on a mission to understand the impacts of climate change and how to stop it. She brings viewers along to learn where we are and where we’re going as greenhouse gasses reach record levels. Have we crossed major climate tipping points? And are there positive tipping points that will help slow global warming faster than expected?

Can coral survive record ocean temperatures? Will thawing permafrost trigger runaway warming? How do we cool our cities and replenish groundwater? Watch to find out!

The first tipping point is the loss of coral reefs through coral bleaching, the subject of Emmy winner Chasing Coral. I haven't examined the subject during the six years since, so thanks to Maiya May and the Weathered crew for getting me to blog about it again.

The second tipping point is the permafrost thawing, which is predicted to release enough methane to speed up climate change. I've written more about this topic than coral bleaching, although my most read entry about it, Vox explains how thawing permafrost is already releasing dangerous diseases, focused on one of the secondary effects, a possible pandemic released from the ice. Considering that I wrote that in November 2019, it was accidentally prophetic, even though COVID-19 didn't come from the Arctic.

The description mentioned groundwater, but the video itself didn't include anything about the subject. Just the same, reading it reminded me that I show a Wall Street Journal video about groundwater depletion to my students and I should embed it here. I should also embed the next episode, which PBS Terra uploaded yesterday. That won't happen until next month. Stay tuned.
