I though if the Yellowstone super volcano erupts our global warming issues are solved for decades?

There have been many climate catastrophes over the eons of Earth geologic history. Most have been started by a big release of carbon dioxide from volcanoes. But now humans are putting a similar amount of carbon dioxide into the atmosphere. If we can't take a lesson from Earth's past, we are doomed to repeat it.

Things are going to hell fast. Without draconian cuts in emissions now it could spell the end of modern man:
good, we deserve it.

I was running a low concentration CO2 analyzer yesterday on a stack
and between tests I could read the ambient CO2 concentration
it was 520 ppm there in Torrance California
the 407 ppm is out in the middle of the ocean, so it's considered the average Northern Hemisphere concentration
it's a lot higher in cities

Craig,

What is that?

Yes, I'm a source tester, which is a person that measures industrial pollution emissions
I've been doing it for 32 years
Low concentration CO2 analyzer = measures CO2 to ppm level
stack = industrial emission exhaust chimney
usually we use CO2 analyzers that measure in the percent range
since most combustion sources emit from 5 to 12 percent CO2
so I rarely measure ambient concentrations

Cool, Craig.

So cool Jeremy
Where are you located?
Dave Wonderly and DE EE are also source testers
I got them into it 25 years ago

It's easy to imagine all these climate-induced horrors will occur, with devastating consequences.
History tells us, however, that it's the unexpected catastrophes that actually do the damage.

NASA Reports 7 Months In A Row of Warmest Earth Temperatures On Record: October 2015 to April 2016.
“Every month from October 2015-April 2016 has now had a departure
of 1 degree Celsius or greater above the 1951-1980 average used by NASA.
The departure from average in a single month had never exceeded
1 degree Celsius prior to October dating back to 1880.”

John, you mean like a chin-up bar collapsing?

People study the Permian extinction, which now appears to be caused by massive lava outpourings in Siberia. Lots of noxious gasses were released along with Co2, probably enough to totally change the climate. There may have been other factors as well.
The extinction may have taken place over as little as 20000 years which is a very quick event in geological timescales.
One frightening finding is that we are releasing Co2 at a faster rate than thought to occur during the extinction. It may not be valid to make a direct comparison as conditions were quite different back then.
I haven't included links but check out information from MIT on their research.

Nothing like falling on your ass when your chinning bar collapses to make you appreciate the threat of global warming.

How about an expected catastrophy like Yellowstone blowing? Or massive solar storms that destroy the electrical grids?
It will and it could be very big.
We don't know when
