SR 1.5 recommended we stay below 1.5ºC by 2100, yet oddly allowed for overshoot pathways. An overshoot would cost us in biodiversity and global food security, as well as further weaken the climate by accelerating warming past more tipping elements. Image
To avoid hitting more tipping elements, we need to switch from fossil fuels to renewables asap, increase energy efficiency, & deploy more renewable power. All the while increase DAC R&D. Tons of room for innovation here! IEA is already planing iea.li/2VQB0Pn
Unlike the Koch/Mercer/Bannon spread&subsidized doom, gloom & gaslighting and false reports from the climate deniers, there will be a full job ecosystem in STEM fields and sales, management, etc. to be had if we supercharge the Green New Deal. economist.com/the-world-if/2…
Instead, if we wait past 450 ppm or 1.5ºC to go neutral (predicted in the mid-2030s), averting the Climate Catastrophe will be ridiculously more expensive to fix, and we would have to pull out radically more CO₂ with an already further damaged climate. ImageImage
What to be done? Take the leadership position, grab those rarely gifted first-mover advantages, make $$$ deploying, and regreening the new economy while quickly tapering back on fossil fuels. #innovation #Entrepreneurship #carbontech #stem #greentech #afforestation/reforestation
And what to do right now? Besides using fewer fossil fuels, Help the air miners scale! @airminers airminers.org

@iAyori No, but I usually make into a tomato marinara sauce base. Can be used for pasta and pizza, and any other recipe that uses tomato/tomato paste/etc.
@iAyori I'll have to remember the proportions...
spices: oregano, marjoram, italian parsley, thyme, 1 tiny bit of rosemary if fresh
1/4 onion, 3-5 cloves garlic, add spices, light sautée reduction in EVOO low then med heat,
(pinch of all the spices, adjust per dish) ...
@iAyori Cook till garlic is golden brown,
Pull the garlic pending on dish, (more garlic flavor, leave it in, otherwise its a chef's appetizer.)
Then add tomatoes, stir, and simmer.
If the dish doesn't need further cooking then med simmer till tomatoes & spices and oil are fully mixed.

1/ I took a look at the poll data taken 09/8-09/9 2020, just as the epic smoke started to hit the entire West Coast.

(West Coast NOAA Data 9/9)
2/ The details of the poll are fascinating! There's actually a majority to 60-70% majority for many pro-climate topics. Remember, this poll was taken as the smoke started to hit the entire West Coast. I'm not sure how many west coast ppl were participants.
3/ Question 11 is a beauty!

See page 45! Majority support to supermajority support for GND, decarbonizing the grid by 2035.

1/ I was tracing out how much carbon we should remove to get a nice climate by 2100, & found that we should realistically remove all we've emitted based cumulative emissions listed in the Global Carbon Project and wrote about it in my preprint paper: doi.org/10.1002/essoar…
2/ The paper says if we act fast enough (i.e. before setting off more tipping points), we just need to remove all the CO₂ we've emitted. I ended up seeing in the experiments, was we must also stop using fossil fuels, to get to about <0.1ºC by 2100. bit.ly/cdrmexprj Image
3/ The 15 tipping elements are outlined: doi.org/10.1073/pnas.1… & quantified in the supplemental materials. Additionally, an older tipping point was highlighted by @DrJamesEHansen which is that we should definitely not exceed 450 ppm. doi.org/10.2174/187428…

An interesting article and thread showing how women can improve productivity for Japan.
'Japanese workers simply waste a lot of time. Crushingly long hours in the office leave them too exhausted to be fully productive. Companies tend to value employees based on how much time they put in, not how much they actually get done.' @Noahpinion
A bit shocked to see the percentages below 30% for women in government. Hopefully, ppl will make headway towards equality.

So, yesterday I feel like I snuck out of the house... I went riding to Mt. Tam. I talked to no one. My only interaction was with the road, traffic, smokey air, touchless paying for gas w/ my phone as I had full protective gear. Felt like discovering a new country. ...
I would visit this area often as a child and teen, so to see the low visibility from ash and smoke, mixed with the marine layer was rather new. It didn't feel like those childhood memories, the majestic cannons that meet Muir Woods now obscured by smog. ... ImageImageImageImage
It felt like we burned Endor. The acrid smokey air mixed with the lush backdrop of overgrown evergreen forests. COVID lockdowns, and rains have really made the entire area extra lush. Under the ashy-smokey air, you could feel the forests breathing. ImageImageImageImage

Megafires and Climate Change thread
Active Pacific Tipping Points:
* Pacific West Forests destruction, from Washington State to Mexico, a larger forest area than just Boreal forests
* El Niño-Southern Oscillation

Climate change cause: red and brown bars, Fossil Fuel emissions since 1750, and land-use change since 1750. CO₂ Emissions get absorbed by either land in green, or oceans and air in blues. Oceans & air increase in CO₂ concentration cause warming and ocean acidification.
2/4 ImageImage
Some of the earlier pink bars are El Nino years.

These should not be seen as a safe target to return to.
By 2100 we should reach for the bars in darker blue not just salmon which is <1.5ºC.
