PPM of CO2 in atmosphere is what was shown 3 days ago. Today the site shows unavailable. But it was 280ppm at start of industrial age. 422ppm of CO2 is going to without doubt go right past the 2C agreed on at Paris because at 2C it was still thought that we could deal with it. We certainly did not want to stress out poor corporations and be meanies asking them to clean their processes up and their house because OMG it would have impacted us also and made some things a bit harder & well, shit cant have that
no,no,no all those poor CEOs would have lost money for share holders and HFS
so we said we will give 2C but no more
well at 422.23ppm of CO2 we will blow right past 2C, its easily going to go to 5C which ends most life, likely its gonna to be 8-10C+ easily once temp catches and stabilize.
Heat is everything in this set up of sun / planet / solar system. Because the natural state of space is very very cold. A 5C uptick in temp changes everything and kills a lot of life. Weather patterns, ocean currents, migration, jet streams, sea level, the very cycle of night and day. There are many system that depend on the cooling night brings to survive. Many Ocean systems will simply collapsed and disappear except for the very deep systems that already live in ~800c water temps. Human population will shrink by billions. Right now we would need 2.3 more Earths to feed the population if food had to be made naturally. Its only through high volume mfg food production that 8 billion can be sustained and big, huge part of this is weather. As patterns change rain will move and the bread baskets we depend on for life are gone. As rain changes snow pack also changes. Rivers we have depended on for 1000s of years will dry up / change course. Everything expands when it gets hot the oceans do this too they are huge heat will expand the water which will cause sea level rises along with melting snow now.
and I have not even gone into these tipping points where systems will reach a point that nothing we do will be able to reverse it. Look at Perma Frost huge swaths of perma frost are thawing. Perma Frost holds Methane which is 4x worse than CO2 for trapping heat. Look at the giant holes they are finding the Cryovolcanoes they are called. Greenland is another. The sea ice around Greenland does not have to melt it just has to get weak enough it no longer acts as a dam holding back to the glaciers inland in Greenland that gravitationally want to slide off the land into the Ocean once that starts there is no stopping it until its run its course.
By 2100 everything you see and know today will have begun to change in ways that we cant predict because we do not have a comprehensive understanding of how all this goes together and works as well as it does to say how it falls apart from heat.
The Earth is like a Horse in a way. It is a huge powerful animal but it still has weak ankles and if one breaks thats it, its over for the horse unless its won lots of $$$ already. Every bio/weather system on Earth has parts as delicate as that ankle even though its a huge planet these achilles heels exist all over. Crucial points that are not robust, tough enough to with stand just a couple degrees rise in temp it will end them.
From CO2 Daily:
As of April 2023, the concentration of carbon dioxide (CO2) in the atmosphere was about 410 parts per million (ppm). This is a 50% increase from the 280 ppm recorded before the Industrial Revolution. The current concentration is the highest it's been in at least 3 million years
3 million years.
Uninhabitable Earth by David Wallace Wells tells an unvarnished, massaged truth on climate change. Anyone whose timeline extends into the 2060-2070-2080s and on I would recommend reading. To get at least a partial view about what is already baked into the system that IS going to happen.
I dont know that there is a way to prepare for a total planet wide disaster like whats coming but we told ourselves get under the desk when you see the mushroom cloud and you will be fine
FFS, so maybe there is?
