We don’t know — Arctic methane says so

We don’t know how long we have.  The more we heat up the planet, the more we reach “tipping points,” where “positive feedback loops” that we set in motion become Earth’s way of consuming itself.  Our models for predicting effects of human-caused climate change do not — cannot — take into account the potential for the feedback loops running out of control, beyond reach of any mitigating efforts we may make.

So, what, then?

We have to simply stop feeding carbon into the air.  Just stop, in every way we can, as much as possible, everywhere, and punish those who resist.  They don’t call it “an existential threat” for nothing.  Why treat it as less?

Lesser efforts, lesser objectives, raise the risk beyond our ability to measure, as shown below in the new PBS Nova episode, “Arctic Sinkholes.”

As the authors explain, the craters look like sinkholes to the naked eye, but they are not sinkholes.  They are massive, explosive and incessant methane leaks from the arctic permafrost.

The rate of increase in the arctic temperature is twice that of the planetary average.  The permafrost — ground frozen continuously for at least two years, but also thousands of feet deep for millennia — is thawing, and opening big methane vents at alarming rates.

We don’t know how many there are, or will be.  We don’t know their ultimate effect.  We don’t know if our feeble efforts to stop killing our planet can begin to take into account the effects of thawing permafrost.

Historic Public Lands Legislation

This is a follow-up to my earlier post, Renew the EXPIRED Land and Water Conservation Fund #SaveLWCF of .

Congress passed a Public Lands Package (S.47) in nearly unanimous bipartisan fashion.

Every so often Congress overcomes its partisan battles and joins together to enact critical legislation. Today is one of those days! Congress just passed a Public Lands Package (S.47) in nearly unanimous bipartisan fashion (92-8 in the Senate and 363-62 in the House of Representatives). The legislation is far-reaching in scope (read it all here). Among the many provisions it creates new National Monuments honoring civil rights icons and Civil War heroes, provides over 1.3 million acres of new wilderness designations, and prohibits mining near two National Parks. Highlighted below are some of the key provisions for hikers and public land lovers.

Wise and Chatty Trees

“As you’re walking through the forest, under a single footprint there’s 300 miles of fungal mycellium stacked end on end. … Can you imagine the activity that’s going on there? … Can you imagine that every time you walk, you’re on this big superhighway with all this stuff moving around all over the place? It’s huge!” —The Science, Culture and Meaning of Forest Wisdom, a talk given by Dr. Suzanne Simard, Ph.D.

You might say this post is about the bio-psycho-social life of trees and people who study them, how a scientist became a forest ecologist, survived a grizzly bear multiple times trying to figure out how trees talk, and helped her Grandpa rescue their dog who had fallen into the outhouse hole.  Fun stuff!  I also want to recommend the book excerpted below.

Global carbon emissions reached a record high in 2018. It’s not Kansas anywhere anymore, Toto.

Sing along: Somewhere over the rainbow oceans rise …

“The figures suggested there is no clear end in sight to the growth of humanity’s contribution to climate change.”Between 2014 and 2016, emissions remained largely flat, leading to hopes that the world was beginning to turn a corner. Those hopes appear to have been dashed. In 2017, global emissions grew 1.6 percent. The rise in 2018 is projected to be 2.7 percent.”
