I previously 👇 documented 20 mechanisms through which climate change is 𝘢𝘭𝘳𝘦𝘢𝘥𝘺 disrupting food production.

Below I am adding to the list including several newly documented mechanisms. 

 *thread*

 Several primary impacts relate to altered soil & plant chemistry & biology:

1. Disruption of the phosphorous cycle - the second most vital element for plants after nitrogen
https://t.co/469VD58O9x
2. Decreased content of key nutrients in major crops 

https://t.co/NollJV7ey7
3. Reduced chill hours required for many plants to bloom normally in the spring

https://t.co/yfHFIPZWDt
Other additional primary impacts include:

4. Fossil fuel pollution impacts on crops - this is not a result of climate change per se, but is included since it is due to the same root cause (fossil fuel use):
https://t.co/JJ2Sd0PImH
5. Severe crop damage from wind storms - in this case, ~$7.5 Billion in damage from a single storm:

https://t.co/zGxdZ43wei
6. Also wind (& heat) related - increasing prevalence of ‘furnace winds’. 

-these are as bad as they sound - they can damage crops in a few short hours:

https://t.co/43Zh8GhzY6
7. And another phenomenon that is an intensification of the existing- “flash droughts”

https://t.co/sDoYbAJUnA
New secondary factors include:

1. Hoarding - even at the national/international scale - something we have disturbingly see with #COVIDー19.

Don't expect your neighbours and allies to come to the rescue:
https://t.co/T9FAWPFFl8
2. Farmer mental health taking a toll - in the U.S. (https://t.co/V5EQraftiu) and internationally, in extreme cases leading to suicide (https://t.co/VFIe2ipZZy)
Most worryingly, we are now seeing a rapid increase in frequency of extreme weather, whereby farmers are being devastated by 2, 3 or sometimes more incidents in short succession. Recent examples:

a) South Korea hit by a succession of typhoons: https://t.co/UlTGsImjXB
b) In the US: flooding, drought and a derecho storm in Iowa

https://t.co/ZCbQTb9EgR
c) in the UK - Farmers have experienced 'pretty much every weather extreme possible' over the past 12 months

https://t.co/6UKaRuChMo
d) some Australian vineyards have faced "frost, flood, insect attack, bushfire & one of the worst droughts on record— all in the last 18 months"

I don't have time to make this detailed, but here's a little thread about the world's first major politically-charged blackout that was blamed on renewables, in South Australia, in 2016............

On September 28, 2016, an unprecedented tropical storm progressed rapidly across South Australia. Truly - this thing was unusual. The sky folded in on itself. It tore towns to bits.


Australia's @climatecouncil pointed out that the storm was so unusual at least partly due to the influence of climate change, and that this is due to get worse.

https://t.co/76ekkfJpR8


I'm going to use brief snippets from my book to fill this out! The storm's primary impact on the grid was the destruction of several major transmission lines. When I say destruction - I mean they snapped like twigs.


Here's what happened in the following seconds:

- A voltage spike from the line falls
- Wind turbines automatically shut off due to software settings that trigger shutdown during a spike
- The interconnector to Vic tried to compensate, failed and died
- All of SA blacked out

What were the big energy and climate surprises of the Trump era? Four years ago, I described the most plausible arc for US climate policy under Trump (it was a boring, safe bet) but expected there'd be unexpected developments too. So how about a look back? https://t.co/1Valz4eTEg


1) The pandemic was a huge surprise, obviously, though maybe it's too early to say how that will affect the energy/climate landscape. So far, it’s put a brake on U.S. fracking and induced Europe to pledge staggering sums on hydrogen. Maybe global CO2 emissions have peaked, idk.

2) The growth of battery storage on the US grid has, I think, been a surprise. This interview with @jburwen does a nice job of laying out the truly staggering changes in the storage landscape since 2015, driven by falling costs and some key policy changes.

3) The impact of the IPCC report on 1.5°C was surprising to me. I often wondered what'd happen once it became clear that the world was unlikely to stay below 2°C. Instead, the climate community and world leaders rallied around an even more aggressive, harder to hit target!

4) It was not obvious that Trump's retreat from climate action would spur states, cities, companies, other nations to make even more aggressive net zero pledges of their own. But that’s what happened—those pledges have really proliferated at a scale that’s been surprising to me.

Many wonder how epidemiology could have become so politicized. But epidemiology - like climate science (the other "mysteriously politicized" subject) has intrinsic politics: to take epidemiology seriously, you have to acknowledge that our species has a shared destiny.

1/


Much of the debate over "liberty" can be summed up as "you do you" - I'll swing my arm over here, you keep your nose over there, and so long as we both respect each others' "freedom," I won't punch you in the nose and your nose will remain unpunched.

2/

This breaks down when applied to epidemiology: "You wear your mask, I'll leave mine at home, and we'll both exercise our freedoms" is like "You swim in the no-pissing end of the pool, I'll swim down here in the pissing end, and we'll both get our way."

3/

We're in the same epidemiological pool, and the science is clear: masking's benefit is primarily in protecting others from you - your presymptomatic, asymptomatic (or symptomatic) spread of particles. Your decision not to wear a mask puts me in danger.

4/

If your worldview ascribes political outcomes to individual choices (implying that poverty or misfortune are the result of a combination of laziness and inferiority), then anything that demands a systemic view challenges its very foundations.

Oh fuck. I am listening to Gormley's interview w/ Patrick Moore about climate change from Jan 21. Gorm is being fed a pile of horseshit and just happily swallowing every word. This is garbage. /1

Moore says you can't go out in the field & see what CO2 is doing. Which is just false. You can go in the field & measure atmospheric CO2 & its change directly. And he calls himself a sciencey guy? /2

Then he's saying, b/c some on the left believe GMOs are bad w/ no evidence, therefore everything they believe they believe w/ no evidence so therefore scientists who say the climate is changing are making up stories? This is ridiculous. /3

Often when I tune into climate deniers, there's stuff I hadn't heard before that I have to do a bunch of reading to find out what's real & what isn't. So far with Moore, I don't even have to make a list of stuff to check to know this is all nonsense. /4

I'm saying, he's going over old, long debunked talking points. This is tired & boring. /5

Now, before the stupid conservatives begin sneering and laughing AGAIN about climate change and a massive snowstorm, one more time trying to educate:

A warming climate causes extreme weather events, *including* huge snow and plunging temps. 1 example why: (Note: I realize.../1

...that no matter what is said, anti-science and arrogant conservatives who failed high school science will still sneer and laugh because this is more complicated than "temp goes up, it gets cold. HAHAHA!" Plus, they don't wont read anything longer than 20 words. But this.../2

...will at least help reply to their foolishness.)

Here is what is happening right now: there is a large area of low pressure and cold air at both poles. That cycles around the poles and is contained there by higher pressure surrounding it. However, a warming planet changes.../3

...that. The higher pressure/low pressure contains the cold air, but as that warms, what essentially serves as a fence weakens. Plus, simultaneously, the warmer climate is changing the jet stream. Even before this, sometimes the contained area expanded and hit the jet stream.../4

...which brought the polar cold down, thus plunging temperatures. However, with a warming climate - because of the change in pressures and the moving jet steam - the polar air is coming down more frequently. A few years back, *Texas* was hit by polar air. That's how far down.../5

Ok, I'll hop on this Elizabeth Warren/Native American testing bandwagon (gently and non-politically).

I've been a @23andMe customer for a while, and have followed their ancestry updates closely.

All is more or less as expected....except for this bit about Native American.


The family is almost completely composed of Spanish peasants (from various regions) who emigrated, along with a massive wave in the late 19th-cent./early 20th-cent., to Cuba back when it was a booming economy (richer than Spain's) and worth emigrating to (Communism killed that).

Also, the native population of Cuba was annihilated early on---was the first place the Spanish colonized after all. Having a native background in Cuba would be like having the same in, say, Massachusetts, particularly if you're (say) mostly Irish. Just really, really unlikely.

(Note: the North African/Arab background is less mysterious. The Iberian peninsula was part of the Muslim world for centuries. It would be odd *not* to have some Arab/Middle Eastern background coming from Spain. Given the family is mostly from Northern Spain, it's small though.)

I have a Spanish passport, have been back to the ancestral villages in Spain, seen the church where my grandmother was baptized, my grandfather told me stories about growing up as the child of Spanish colonists in rural Cuba. The native bit just clashes with all the family lore.

Sri Devi Karumariamman mandir, Chennai, Tamilnadu

Sri Devi Karumariamman mandir is in Thiruverkadu, a suburb of Chennai. It is said that God Muruga came here and obtained the 'Vel' (spear) from His mother, Goddess Karumari (an avatar of Parvathi) 1/n


to fight the demon Suran and hence this place was called as 'Vel kadu' and became as Verkadu. As per legend Devi Karumariamman once disguised as a soothsayer visited Bhagwan Surya, the Sun God, to predict His future. 2/n


Not realising that the soothsayer is none other than Sakthi Matha, Surya ignored Her. Angered by his indifference, Devi Karumariamman immediately retreated. Bhagwan Surya lost His glory and the earth plunged into darkness. 3/n


Bhagwan Surya then realised His folly and pleaded forgiveness from Devi Karumariamman. In order to pacify mother Karumariamman, Suryadev said that His rays would fall on Her directly twice in a year and touch her feet. (in the month of Panguni (March- April) & during (Sep - Oct)


Mother Karumari Amman is worshipped here in two forms.A swayambu (self manifested) with only head visible above the ground and another one in a graceful sitting posture with all Parasakthi features,with four arms holding skull, sword, trishul, udukkai (damru). 5/n

Do you know?

The Golden Shine on the artificial jewellery of modern times is a gift by Nagarjuna.

Now,u might be wondering,who is Nagarjuna?

Nagarjuna was the name of an ancient Indian scholar&scientist whose name is associated with the fields of Alchemy,Chemistry& Metallurgy.


He conducted a number of alchemic and Metallurgical experiments directed towards transforming base elements into Gold.
According to Eduard Sachau's Alberuni's India, Nagarjuna was termed as a Metallurgist who was born 100 yrs before Alberuni's time, who was born in 973 CE.


According to some records Nagarjuna was born in 9th century CE near Somnath,Gujarat and according to some Tibetan & Chinese sources he was born in Vidarbha,Maharashtra from where he later migrated to Deccan region.


Edward Schau quotes in his book,'They have a science similar to Alchemy and Nagarjuna is famous for this science which they call as 'Rasayana'.

Nagarjuna's book 'Rasaratnakara' is one of the earliest documented texts on Alchemy,Chemistry & Metallurgy in Sanskrit.Nagarjuna successfully discovered through his experiments the alchemy of transmutation of base metals into Gold.This was not real gold but a gold like substance.
