Despite Trump-Musk Feud, CO2 Milestone Is the 'Important News of the Day'

Source: CommonDreams.org

Carbon dioxide has been accumulating in the atmosphere due primarily to the human burning of fossil fuels, as well as by the clearing of forests and other natural carbon sinks. There, it acts as a greenhouse gas, trapping heat from the Earth, and is the primary gas responsible for the rise of global temperatures by approximately 1.1°C from the 1850 -1900 average. This warming has already had a host of dramatic impacts, from extreme weather events to sea-level rise to polar ice melt, and scientists warn these impacts will only accelerate under current energy policies, which put the world on track for around 3°C of warming by 2100.

The last time that atmospheric CO2 concentrations topped 430 ppm was most likely more than 30 million years ago, Ralph Keeling, who directs the Scripps CO2 Program, toldNBC News.

"It's changing so fast," he said. "If humans had evolved in such a high-CO2 world, there would probably be places where we wouldn't be living now. We probably could have adapted to such a world, but we built our society and a civilization around yesterday's climate."

But, by all means, let’s focus on the dumpster-elania debacle.

We said this, and I felt it since I track it, at 380, 390, 400!!!, 410, 420 and now 430 ppm. NNadir 18 hrs ago #2

It's like that moment, if you've ever been in a major crash, that you realize that the crash is going to happen.

It's not really "news" at this point. It's like reporting that the occurrence of the dawn is "news."

We are not doing a damned thing to address the issue, although there are some among us who claim that so called "renewable energy" is "something."

It isn't.

My crude model, a simple quadratic from two integrations with data as boundary conditions, that we will hit 500 ppm somewhere around 2045.

...If one looks, one can see that the rate of accumulation recorded at the Mauna Loa CO2 Observatory is a sine wave superimposed on a roughly quadratic axis:



Monthly Average Mauna Loa CO2

Referring to the crude quadratic axis in the graphic above, one can make a rough model of the behavior of this system, using simple high school level calculus, by treating the rate of change in the rate of change - the change in the 52 week average comparators - as a second derivative with respect to time (in years), integrating twice, and using, as boundary conditions, the 1 year comparator, and the current reading. In my spreadsheet I do this automatically. If one solves the resulting equation using the quadratic formula to see when we will hit 500 ppm, one will see this should take place in 2046. (I will be dead then, and not live to see what little warnings I offered here.) The crude equation predicts that in 2050 the concentration of the dangerous fossil fuel waste will be somewhere between 515 and 520 ppm.

The same media that has loved to promote a seriously intellectually crippled serial rapist, con man and felon as a viable Presidential elect likes to talk about a so called "energy transition" that is supposed to save our asses.

This highly advertised propaganda is connected with the unsupportable belief that the vast sums of money spent so called "renewable energy," which I personally regard as reactionary as the six thugs of the apocalypse in the rogue US Supreme Court, is about addressing climate change.

It isn't...
