BC CLIMATE CHANGE
Saved by @CodyyyGardner

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).
APRIL was hottest on record. North America pretty cool, quite impressive actually. But elsewhere...

Heat in the Arctic becoming quite a theme. Stick with me...
MAY... hottest on record for month of May.

Do I need to point out northern parts of Asia any more?

Permafrost thawed and Russia suffered extreme diesel disaster. It began at the end of May. Criminal investigation ongoing: https://t.co/XC74Rx9tev
The Arctic circle broke its all time heat record in JUNE and the globe recorded its hottest month of June on record.

Arctic heat record: Siberian town called Verkhoyansk logged a temperature of 38° Celsius (100.4° Fahrenheit) on 6 June.
JULY was second hottest on record (July 2019 was hotter globally).
AUGUST... 3rd hottest on record.

Siberia and parts of North America really in the furnace, quite literally as wildfire season blazed into unchartered territory.

1,032,648 acres were lost in the August fire complex (Northern California) alone in. Record books were re-written.
SEPTEMBER... hottest on record.

South America stepped into the furnace with the start of one of the most profound/long-lived and widespread heatwaves in Southern Hemisphere history.

Siberia still doing its thing. Greenland turned blue though.
OCTOBER... 5th hottest on record globally.

Arctic sea ice melted to record low extent for month of October and South America and started the month with extreme heat. Eastern Europe/Asia boundary set heat records widespread.

Cool north America and developing La Nina...
NOVEMBER marks the 6th all time monthly heat record in 2020. 2020 now contains at least half the monthly heat records globally.

Arctic looks like it is on fire here. This is not surprising given the lack of sea ice. Textbook Arctic amplification.

Cold in central Asia.
DECEMBER... well... I await official stats for ranking.

Deep cold again in Central Asia but warm pretty much everywhere else. North America, Northern Europe and Africa breaking records.

Stay tuned.
This is not an exhaustive list of records and profound weather/climate events from 2020.

A more organised collection of graphics exists on my instagram: https://t.co/3IOp4bew5f
COVID and politics took centre stage in 2020 for very obvious reasons.

This thread serves as a reminder that the climate has changed and is continuing to change. Changes are not uniform, I hope everyone can see this.

To those who kindly keep pointing out that my previous animations have the world spinning the wrong way.

I have corrected this. Happy new year 👍
We are awaiting official verification as to whether 2020 was the warmest year on record.

Inevitably top 3. Probably at least 2nd. Could be hottest.

JMA preliminary data has 2020 at the top spot.

It is worth noting that some months are warming faster than others too.

Often January, February and March have the largest anomalies, some of which already break the +1.5 °C anomaly (comparing to levels similar to pre-industrial times).
Oh... I nearly forgot.

This might come in useful. Solar and carbon graphs combined with temperature.

1/13 #ClimateChange is a result of a mindset, that is based on monoculture, fossil fuels, chemicals, corporate control. @BillGates cannot alter a condition with the same mindset that created it in the first place @Trevornoah @drvandanashiva

2/13 The mad rush for #FakeFood and #FakeMeat, ignorant of the #diversity of our food cultures & the role of biodiversity is a recipe for accelerating the #climatecrisis, the destruction of the planet & our health @drvandanashiva

3/13 The perpetrators of the industrialized & now digitized predatory economic model that has led to worldwide ecological devastation are trying to sell us their solutions as the only path forward @drvandanashiva @NnimmoB

4/13 The #GatesFoundation works to create a friendly regulatory environment to push its innovations regardless of risks or past failures by funding to align to its interests- media, research, start-ups, government programmes & international institutions

5/13 Amnesia and denial of past failures becomes evident with the @gatesfoundation new initiative #AgOne where only digital tech and the #GreenRevolution is seen as the solution to the #ClimateCrisis & #BiodiversityCrisis @drvandanashiva

EU Summit just agreed a “binding EU target of a net domestic reduction of at least 55% in greenhouse gas emissions by 2030” - so UK going somewhat further at 68%...

That is in reference to 1990 carbon emissions - which is the standard point of reference

VDL trying to sound conciliatory - making point about the ratchet clause that all sides “remain free - sovereign” to do what they are want as regards matching future increases in regulations, but that both sides should retain right to adapt conditions for market entry

On fishing VDL says UK must understand legitimate expectations of EU fishing fleet based on decades and sometimes centuries of access ...

journalists at the EU summit seem more interested in asking Merkel/ VDL about Turkey than summit Brexit discussions, so far zero questions - some informational value there ...

Long thread here... from Keith, on tree guards:

I really don’t want to spread 120,000 plastic tree guards across the side of our lovely hill, the hill where I grew up and now farm, on the eastern edge of the Black Mountains. So, I’ve taken a good look at the pros,... 1/25


the cons and the alternatives, to try and decide rationally, which is the best approach for our plant on the Bryn Arw.

It has become the accepted norm in the UK that to plant a tree, you need to put your sapling in the ground and then wrap a plastic tree guard around it.

This is simply ‘how it’s done’ now. This practice uses a huge amount of plastic; worse still, it disperses plastic extremely efficiently around the countryside. In some rural places, un-retrieved tree guards are by far the biggest source of plastic pollution.

And yet the first commercial plastic tree guards only came on the market 38 years ago. There are many perfectly healthy woodlands and trees that are older than this, and which became established without plastic – which begs the question: do we really need guards?


Plastic tree guards have several uses, some of which did revolutionise tree planting when they first came out. In particular, they:
•protect your saplings from things that want to eat them;
•provide a microclimate, which enhances tree growth, according to the manufacturers;

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

This #NewYear we must get serious about climate change. A big obstacle: our brains.

Current risks are vastly different from our ancestors, but our brains are wired the same. Knowing the science behind decision-making helps us better talk about climate threats & spark action. 1/

I’ve dedicated my career to understanding what factors influence our perceptions of risk & shape behavioral outcomes, especially around climate action.

We clearly do not judge risks accurately. Let’s try this example. What is more likely to kill you:

Ppl often say shark attacks even though plane parts are 30x more likely to kill us. Attacks are more sensational/easier to recall.

Brains react in certain ways to risks around us, rapidly scanning environmental cues (e.g. snake’s stance) with subliminal and automated processing.

How does brain wiring relate to climate action? We're influenced by triggers such as if we can see risk or if we trust who communicates it to us.

Bluntly, we overestimate unserious risks like vaccinating children and underestimate seemingly far away risks like rising sea levels.

Sociology shows how even political identities influence risk perception. A human evolutionary trait allows us to avoid cognitive dissonance from info 1) that isn’t pleasant or 2) contradicts beliefs integral to our identity/tribe. We’re wired to make snap judgements for comfort.

Hey, for people interested in this stuff, here's a thread about a change we made to running our facebook account:

So, about 5 years ago, we got on facebook. Why? Well, facebook has a big audience and they like to consume on facebook. So, we started posting comics there, even though we got paid nothing and facebook made money off the free content.

Why? Because back then, once in a while, you would say "also hey, I sell books" or "hey, I'm going to be signing at this event" and your facebook followers would actually see it.

Effectively, the implicit old arrangement was "facebook lets me reach readers efficiently, and I supply facebook with free content they run ads on."

Over time, like a bad business partner, facebook basically made it impossible to reach your audience without *paying them*. Thus, you supply them free content on which they run ads, and you get nothing in exchange.

Trump is gonna let the Mueller investigation end all on it's own. It's obvious. All the hysteria of the past 2 weeks about his supposed impending firing of Mueller was a distraction. He was never going to fire Mueller and he's not going to


Mueller's officially end his investigation all on his own and he's gonna say he found no evidence of Trump campaign/Russian collusion during the 2016 election.

Democrats & DNC Media are going to LITERALLY have nothing coherent to say in response to that.

Mueller's team was 100% partisan.

That's why it's brilliant. NOBODY will be able to claim this team of partisan Democrats didn't go the EXTRA 20 MILES looking for ANY evidence they could find of Trump campaign/Russian collusion during the 2016 election

They looked high.

They looked low.

They looked underneath every rock, behind every tree, into every bush.

And they found...NOTHING.

Those saying Mueller will file obstruction charges against Trump: laughable.

What documents did Trump tell the Mueller team it couldn't have? What witnesses were withheld and never interviewed?

THERE WEREN'T ANY.

Mueller got full 100% cooperation as the record will show.

Varahi Amman, Madurai, Tamilnadu

Vaarahi is one of the Saivite Shakti deities with the group of goddesses known as SAPTAMATAS.
They are: Brahmi, Maheshwari, Kaumari, Vaishnavi, Vaarahi, Mahendri and Chamundi. 1/n


They are the Shakti (female) equivalents of their male counterparts. Vaarahi is the Shakti of Bhairavar who is one of the Amsam of Bhairavar.Created from the boar avatara of Vishnu, Vaarahi is often associated with Goddess Kamala (one of the Mahavidyas). 2/n


She is also called Dandini (Lady Commander of the forces of the Mother-Goddess, symbolizing the might of SriVidya). As Vaarahi ("hog-faced" or "the great consumer") she destroys evil forces that obstructs the devotees' progress, paralyses the enemies 3/n


and led the devotees ultimately to SriVidyas. She is also called Panchami). With Kurukalla, she is accorded the parental status to Sri-Chakra (Lalita Tripura-Sundari). While Kurukalla represents the full moon, Vaarahi represents the new-moon. 4/4

Jai Maa Varahi 🙏

1/ Someone emailed me asking how to break into VC, so I wanted to answer on Twitter where others could see and contribute to the conversation.

2/ “Being a VC” can mean a lot of different things, so it’s worth asking:

What actual activities do you want to do?

- Deep market analysis?
- Be in the flow of information and people?
- Make deals?
- Work closely w/ founders over time (e.g take board seats?)
- Manage capital?

3/ It’s worth specifying what type of VC you might like to become — as there are different archetypes. E.g.

- Benchmark (Lead series A/B - couple investments a year)
- First Round (Lead seed rounds, partner w/ a few companies a year)
- SV Angel (Make lots of seed investments)

4/ Continued:

Expa - Incubate companies

YC / Village Global - Build a platform to help entrepreneurs at scale

Do you want to join a firm or start one? There’s a lot to consider.

Different paths will require different skillsets & sets of experiences.

5/ Since the person who wrote the email is a young person trying to break into VC by joining a firm (and who doesn’t want to start a company), I’ll tailor this tweet storm to that goal. There’s some overlap.

Starting a startup is hard. This thread will contain some key advice I think are particularly noteworthy:

1. “If you’re not embarrassed by the first version of your product, you’ve launched too late.” - @paulg The first version of my product was not great, but hey, it worked.

2. Don't build in a vacuum. You should build your product out in the open for the world to see. You will gain valuable feedback from users if you build publicly, and provide insights which ensure you are building a product users truly want. cc @rrhoover @sama

3. As a young founder, a massive weakness is age and the lack of credibility. Developing partnerships, trying to acquire customers. etc have all taken so much longer. In fact, when I mentioned my age, a few investors just walked away. cc @Jason

4. Work on what makes you feel excited. Working on something that you don't believe in will cause you to make rash product decisions, resulting in loss of user loyalty. @fredwilson

5. Take care of yourself. While doing the occasional code sprint can be incredibly useful, working 24/7 and disregarding your health just to build a great product is not a wise choice.
