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"

Earth has a fever in more ways than one. Some places averaged + 5-7 °C warmer than normal for the ENTIRE YEAR of 2020.

An enormous area of anomalous warmth plagued Arctic Siberia effectively all year but it was not just the Arctic where we saw record shattering warmth.

THREAD


Another way of looking at it... Very few cold blobs left. La Niña developed and shows up in the Pacific.

The climate is not changing uniformly, the Arctic is warming much faster than the rest of the world.

Data: @CopernicusEU and compares to 1981-2010 average.


JANUARY was joint hottest January globally on record according to NASA GISTEMP v4 (joint record with 2016).

Profound winter warmth for North America plus Europe and Asia.


FEBRUARY was second hottest on record (1st place is still held in 2016).

The winter 'warmth' in Europe and Asia was just insane.


MARCH: A cold Canada, Greenland and Svalbard... but obvious warmth still striking across the continents, particularly northern/central Asia.

This was the second hottest March on record (2016 still holds the record).

The Sixth Carbon Budget (2033-2037) charts the decisive move to zero carbon for the UK. The CCC shows that polluting emissions must fall by almost 80% by 2035, compared to 1990 levels – a big step-up in ambition. (1/12) #UKCarbonBudget 🧵


Our recommended Sixth Carbon Budget would achieve well over half of the required emissions reduction to 2050 in the next 15 years, but decisive action must start today. (2/12) #UKCarbonBudget


The recommended Sixth Carbon Budget and UK NDC also reflect the goals and requirements of the Paris Agreement, recognising the UK’s responsibility as a richer developed nation and its respective capabilities. (3/12) #UKCarbonBudget


When we recommended the UK’s #NetZero target for 2050, we demonstrated that any negative economic impact was likely to be small and the overall impact could turn out to be positive. Our analysis for this report reinforces that finding. (4/12) #UKCarbonBudget


Our estimate of the annualised resource cost (which measures the net additional cost each year to deliver the same services with lower emissions) has fallen to less than 1% of GDP through to 2050. (5/12) #UKCarbonBudget

The UK government's climate advisory body is launching its next carbon budget: basically, outlining what the UK can emit between 2033 and 2037. It's a big deal - launch video starting right now.
Watch along:


Will tweet along snippets. Pretty relevant to...............everything, really. #UKCarbonBudget

"Instead of being just a budget, it's a pathway we have to tread to reach net zero in 2050" @lorddeben

Just like quite a few other modelling exercises, CCC use a spectrum between behaviour change and between technological change. #UKCarbonBudget.

Both = best (just like @AEMO_Media's Step Change scenario in their ISP)


'Balanced' is what they use for their recs. "We're doing 60% of the emissions reductions in the first 15 years, and then 40% in the next".

The slinky kitty curve....good to see. No evidence of delaying action to Dec 29 2049, here. #UKCarbonBudget


"By front loading, we're minimising the UK's contribution to cumulative emissions" - really important point. A slow path to net zero - more climate harm than a fast one. #UKCarbonBudget

As 2020 comes to a close, we're taking a look back at some of our best reporting on the environment.

The American landscape has become 48 times more toxic to insects since the 1990s, a shift largely fueled by rising use of neonicotinoid insecticides.

Banned in the EU, a sophisticated information war has kept these insecticides on the U.S. market.

Amid California's severe wildfires, grape growers in Sonoma County got exemptions to send in farmworkers who have few alternatives or options for support into fire evacuation zones.

With Trump's election, a small and previously marginalized group of toxics apologists suddenly took control over health and environmental regulations, ushering in higher profits for polluters and higher cancer rates for the American people.

Steven Donziger won a multibillion-dollar judgment against Chevron in Ecuador. The company sued him in New York — as of December, he has been under house arrest for over 500 days.

So here is a secret: Not everything I write goes anywhere. I have at least 4 books completely written and edited that never went on submission. I have books that stalled out at 20k. I have docs on my computer with opening paragraphs I don't remember writing. But! 1/

Every now and then an idea sticks with me like that corner of tortilla chip that just won't go down your throat. It happened with SPARROWHAWK, which began as 40k of a YA story, died, and was reborn as a comic, thanks to @christopher_j_r and @boomstudios. And now... 2/

It's happening with THE WILLOWS, a short story that you'll see in @UncannyMagazine next year. This Southern Gothic horror story began as an attempt to sell my next Romance to @AbZurdity after the Blud books in 2014 or so. And she didn't buy it. Guess why? 3/

Turns out, it wasn't a Romance! It was Southern Gothic Horror. Even the bones of it screamed strangeness, not sexiness. I loved the taste of the world, but I hadn't found the right story yet. Tried to write it 2 more times and failed. Until I finally understood what it was. 4/

So I took the 50 pages I'd written and cut half of them, twisting the story around from a gothy Romance inspired by the band the Civil Wars and turned it into a spooky descent into madness. And it looked back at me from the abyss as if to say, DUH. Sometimes... 5/

Unfortunately the "This work includes the identification of viral sequences in bat samples, and has resulted in the isolation of three bat SARS-related coronaviruses that are now used as reagents to test therapeutics and vaccines." were BEFORE the


chimeric infectious clone grants were there.https://t.co/DAArwFkz6v is in 2017, Rs4231.
https://t.co/UgXygDjYbW is in 2016, RsSHC014 and RsWIV16.
https://t.co/krO69CsJ94 is in 2013, RsWIV1. notice that this is before the beginning of the project

starting in 2016. Also remember that they told about only 3 isolates/live viruses. RsSHC014 is a live infectious clone that is just as alive as those other "Isolates".

P.D. somehow is able to use funds that he have yet recieved yet, and send results and sequences from late 2019 back in time into 2015,2013 and 2016!

1/OK, data mystery time.

This New York Times feature shows China with a Gini Index of less than 30, which would make it more equal than Canada, France, or the Netherlands. https://t.co/g3Sv6DZTDE

That's weird. Income inequality in China is legendary.

Let's check this number.

2/The New York Times cites the World Bank's recent report, "Fair Progress? Economic Mobility across Generations Around the World".

The report is available here:

3/The World Bank report has a graph in which it appears to show the same value for China's Gini - under 0.3.

The graph cites the World Development Indicators as its source for the income inequality data.


4/The World Development Indicators are available at the World Bank's website.

Here's the Gini index: https://t.co/MvylQzpX6A

It looks as if the latest estimate for China's Gini is 42.2.

That estimate is from 2012.

5/A Gini of 42.2 would put China in the same neighborhood as the U.S., whose Gini was estimated at 41 in 2013.

I can't find the <30 number anywhere. The only other estimate in the tables for China is from 2008, when it was estimated at 42.8.

(THREAD) Pre-election Russia collusion may take down Trump. It's equally possible the Trumps' pre- and post-election collusion with Saudi Arabia, the UAE, and Israel will do it—a course of collusion also connected to the Kremlin. I explain here. I hope you'll read on and retweet.


1/ I must stress how unbelievably complex the "Grand Bargain" theory of the Trump-Russia case is—a different thing from saying it's not substantiated. It's substantiated in *almost every single particular*—it just *also* happens to be very confusing. Not byzantine—just confusing.

2/ The basics: Saudi Arabia, Israel, and the UAE all view Iran as their chief regional enemy. Iran is propped up by Russia. Therefore the Saudis, Israelis, and Emiratis all need a US government willing to find a way to get the Kremlin to *stop* supporting Iran in the Middle East.

3/ The best way to get Russia to stop supporting Iran—or reduce support—was/is to drop all sanctions on Russia over its 2014 annexation of Crimea, as that'd be worth *trillions* to the Kremlin over the next decade. Everyone knew that Clinton wouldn't do this—and that Trump would.

4/ Per the NYT, on August 3, 2016, Donald Trump Jr. met secretly at Trump Tower with a Saudi and Emirati emissary, George Nader, as well as an Israeli intelligence expert, Joel Zamel, with *significant* ties to both Israeli intelligence *and* Russian oligarchs allied with Putin.

MDZS is laden with buddhist references. As a South Asian person, and history buff, it is so interesting to see how Buddhism, which originated from India, migrated, flourished & changed in the context of China. Here's some research (🙏🏼 @starkjeon for CN insight + citations)

1. LWJ’s sword Bichen ‘is likely an abbreviation for the term 躲避红尘 (duǒ bì hóng chén), which can be translated as such: 躲避: shunning or hiding away from 红尘 (worldly affairs; which is a buddhist teaching.) (https://t.co/zF65W3roJe) (abbrev. TWX)

2. Sandu (三 毒), Jiang Cheng’s sword, refers to the three poisons (triviṣa) in Buddhism; desire (kāma-taṇhā), delusion (bhava-taṇhā) and hatred (vibhava-taṇhā).

These 3 poisons represent the roots of craving (tanha) and are the cause of Dukkha (suffering, pain) and thus result in rebirth.

Interesting that MXTX used this name for one of the characters who suffers, arguably, the worst of these three emotions.

3. The Qian kun purse “乾坤袋 (qián kūn dài) – can be called “Heaven and Earth” Pouch. In Buddhism, Maitreya (मैत्रेय) owns this to store items. It was believed that there was a mythical space inside the bag that could absorb the world.” (TWX)
