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"

Thread 1/19


On Saturday 12/12/20 I saw this on a Facebook group of which I am a member. The comment from the poster mentioned it was taken near Langholm in Dumfriesshire.

It appears to show the use of a forestry plough peat soil

2/19


I'm partisan enough to admit that my initial idea was that this might be on Langholm Moor which was the site of a controversial experiment in grouse moor management. I contacted the poster and he sent me this map of the location. Which is not on Langholm Moor 3/19


The location is significant. But before I go into it, a quick explanation of what you are looking at. This photo shows peat ploughed with double mould board forestry plough. Trees are planted on the ridges thrown up, while the furrow drains water. 4/19


The cut in the centre of the furrow is from a 'tine' breaking up a hardened layer of subsoil called an 'ironpan' which inhibits root development. The presence of this pan is the justification for ploughing rather than 'mounding' this site 5/19

It's (nearly) five years since the Paris Agreement was gaveled through… but was it any good? Tricky question. Based on emissions, temperature data and impacts, no. *But...* (thread)

The team at @SystemIQ_LTD have crunched the numbers & reviewed how far + fast sectors have shifted since 2015. Their take is the global economy could be a decade away from seismic tipping points that see the world move fast towards low carbon.

In 2015, zero-carbon technologies and business models could rarely compete with incumbent carbon-solutions. In 2020, zero-carbon solutions are competitive in sectors representing around 25% of emissions. In 2030 the figure’s looking like 70%.


What does this mean for a COVID-smashed world, where 2021 is shaping up to be a hellish mix of recessions and mass unemployment? Well, the 2020s could see a net increase of 35 million low carbon jobs if governments roll out the right policies + invest wisely.

Can the low carbon acceleration be pinned to Paris? Not entirely, but partly. In 2014 no-one talked of net zero targets. Now 120+ countries either have these plans or are working on them. By mid 2021 the US, China, EU, UK, Japan, Korea, Canada will have these targets.

1/ In reflecting on my work this year I have just realized that everything I published concerned climate change: here is a roundup of my 2020 writing on #climate #justice, climate #reparations, climate #debt, climate #displacement, climate #mobilities & #disaster #recovery

2/ My most recent online piece is on #Arctic #Mobilities, #climate #displacement and #Indigenous rights, originating from a great workshop @PennLaw_CERL

3/ Last month I also wrote about #climate #displacement and the case for #climate #reparations and #open #borders for those fleeing climate disasters

4/ Which originally appeared here

5/ Both of these came out of thinking about Caribbean #climate #colonialism and #climate #debt in my book Island Futures: Caribbean Survival in the Anthropocene @DukePress YOU CAN STILL GET IT for 50% off with the code E20SHELL https://t.co/i5DIaNAgsg

Thread on snow ratios. The snow ratio, or snow-to-liquid ratio states how many inches of snow, when melted, yields one inch of liquid water. Ratios are usually around 10:1 or 12:1, but can vary from as little as 6:1 or as high as 30:1, or sometimes more. 1/


There's a common misunderstanding that the colder the surface temp is, the higher the snow ratio will be (fluffier snow). This is incorrect. As long is the surface temp is not close to freezing, it really doesn't matter all that much. 2/

As the surface temp gets close to or exceeds freezing, more snow is lost to melting, yielding lower ratios and heavy, wet snow. The same reasoning also applies to temps above the ground; if they exceed freezing, sleet or rain can mix with the snow, dramatically lowering ratios 3/

Much more important is the dendritic growth zone (DGZ), the layer of the atmosphere with temperatures between -12 and -18C. In this layer, snowflakes grow as dendrites, which can easily clump together into aggregates, which contain a lot of air, increasing the ratio 4/


At warmer or colder temps, the flakes grow as plates, columns, or needles, which don't clump together as well and contain less air, lowering the ratio. To make this even more complicated, there's also a dependence on atmospheric humidity. 5/

FYI - The Storm approaches - take a look...

At the moment, POTUS is sitting on a stack of Trump cards that he's just waiting to unleash...a royal flush!

@John_F_Kennnedy @Pamelal33566076 @GeorgePapa19 @whitebunny @atvguy @stormis_us


He has court cases that will go to the Supreme Court and thanks to the Texas case, he's now aware how to file them properly... under article 3 not 2...

so the SCOTUS will be forced to listen.....He now has the DNI report. Barr stepped down and can now be a witness.....he did his job. Durham is special counsel and can prosecute, in any state....

He’s letting civil, criminal, and federal courts fail to handle the situation properly.....so he can use military tribunals. He has ALL the data from the NSA, the Kraken supercomputer, the Alice supercomputer and likely many more computers, unknown to us....

He has the dueling electors from 7 state legislatures. He has VP Pence, as the final arbiter of which ballots to accept.. the NDAA, the national emergency, the 14th amendment, the 2018 executive order, the 2017 very first EO, the Patriot Act, the FISA warrants,

Post Independence, Army wanted to select the most experienced Indian commander as Army chief. But Nehru without consulting anyone appointed Gen Rob Lockhart, a senior British Army officer as the Commander-in-Chief (C-in-C) of the Indian Army.


Most people were shocked to know that Nehru selected a British Man after fighting for independence for over 200 years! Major Gen A A ‘Jick’ Rudra of the Indian Army was completely upset with the decision.


One day Lockhart met Nehru with a strategic plan and proposed many government directive defence policies for the country. He placed it on the table and explained the point to PM Nehru. After a while Lockhart walked out of the room and met AA Jick Rudra,+

Lockhart looked shell shocked and stunned. When asked what happened he said “The PM took one look at my paper and blew his top. Rubbish! Total rubbish! We don’t need a defence plan. Our policy is ahimsa (non-violence). We foresee no military threats. Scrap the army!”

One year after the incident the Kashmir crisis had increased and Gen Lockhart used to exchange ideas with the Gen Douglas Gracey who was commander in chief of Pakistan Army.There were many infiltrations along the border which Lockhart knew and took no action. But Lt Gen Cariappa+

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/

This is NONSENSE. The people who take photos with their books on instagram are known to be voracious readers who graciously take time to review books and recommend them to their followers. Part of their medium is to take elaborate, beautiful photos of books. Die mad, Guardian.
