PBS Terra asks 'What Will Earth Look Like When These 6 Tipping Points Hit?'

I'm taking a break from entertainment by returning to reality today with PBS Terra asking What Will Earth Look Like When These 6 Tipping Points Hit?

A “tipping point” is when a system, with just a small amount of additional energy, is pushed from one stable state to another suddenly and dramatically. This can be a chair falling backwards. Or it can be a major earth system collapsing.

The IPCC recently identified 15 potential climate-related tipping points that scientists have grown increasingly worried we are getting close to crossing due to global warming. In this episode of Weathered, we look at 6 of the major candidates, how they are all interconnected and influence each other, and what it would mean if they were triggered. These tipping points or tipping elements are the Greenland and Antarctic ice sheets, the Amazon rainforest, global monsoons, the AMOC (Atlantic Meridional Overturning Circulation) and the earth’s permafrost and coral reefs.

The consequences for any of these systems being pushed over the edge would be truly catastrophic and would encompass everything from massive droughts, loss of biodiversity, increased flooding, heat waves, large scale climate migration, food shortages, and much more.
Watching all that reminds me that none of these threats are new, so my reaction isn't either.
First, welcome to the 400 ppm world. Second, are you scared enough by climate change? My readers should be.
Hey, I'm an environmentalist; I recycle.

I'll see if I can resume my awards show coverage tomorrow or if it's easier to stick to reality. Stay tuned to find out.
