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 is our rainbow of abatement" - nice @IEA-style split-out of how to cut emissions to near-zero by 2050. Reducing demand for CO2 intensive stuff (flying, meat) is quite a big purple chunk there. #UKCarbonBudget
This is a really interesting graphic:

Orange = purely behavioural change
Purple = purely tech
Red (pink??) = a mix of tech and behaviour

"There is nothing to be afraid of at all.......they won't be major change to our lifestyles", on the red wedge #UKCarbonBudget
UK will need a huge amount of (mostly private) investment in new zero carbon assets, but the savings from not buying fossil fuels eventually cancel that out.

"Any notion that we can't afford to tackle climate change is clearly nonsense" #ukcarbonbudget
"The challenge is not to rely on a pandemic to cut emissions. The key is to drive changes that last"

CC @AngusTaylorMP #ukcarbonbudget
"We're hitting a million heat pump installations by 2030", in addition to nearly 100% of new car sales being electric (small amount of hybrids) #ukcarbonbudget, w/ 30TWh of H2 produced.

Zero carbon elec by 2035 (just like the US). No new sales of gas boilers by 2033
"The crucial point here is that this is all genuinely feasible......but it is also genuinely challenging" #UKcarbonbduget @ChiefExecCCC
"Gas is not acting as a bridge fuel. It's a fossil fuel and we need to move away from it" #UKcarbondget
Nice comparison of emissions vs temps. The decisions made to cause the problem have mattered - the decisions made to stop it matter too.

#ukcarbonbudget
A familiar accent from @pilitaclark during the Q&A session.... #ukcarbonbudget https://t.co/faxRj5KF8x
"If you take the time to guide people through this, they're really supportive of action" on how to integrate behaviour change into net zero. Can't help but think of toxic UK media outlets and how easily they could ruin all that. #UKCarbonBudget
Aus media and conservatives used a "the government is coming to take your car" narrative in 2019 on efficiency standards and it definitely helped them win an election #UKCarbonBudget
A really interesting point from @ChiefExecCCC - the hard, empirical pathway (spreadsheets) and the qualitative, consultation-led pathway (climate assemblies, etc) both end up in really similar places. #UKCarbonBudget
Lord Deben literally having an air-sourced heat pump installed during the call #UKCarbonBudget
He's got biomass backup #UKCarbonBudget
On heat pumps and the suggestion to phase out gas boilers in thirteen years - these are two headline describing precisely the same piece of news:

#UKCarbonBudget
"While its great to hear commitments to net zero.....the path by which we get there is crucial. It's the accumulated CO2 emissions in the atmosphere that are changing the climate.......they must have a tough intermediate target. The 2030 NDCs are crucial"

#UKCarbonBudget
By 2030, the UK won't be building any more new unabated gas plants (that should surely be.....now, right?), under the CCC's balanced pathway scenario #UKCarbonBudget
UK shifting energy from oil+gas into electricity+hydrogen ends up with a total *lower* amount of energy consumption, because electricity is just so much more efficient.

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;

Fascinating new paper by @AndrewDessler and colleagues arguing committed warming might be higher than expected given historical pattern effects. Its combining a lot of different concepts together, so lets spend some time disentangling them https://t.co/ILi5z515Qy

A thread: 1/19

The paper's headline number is that we previously thought the world was committed to 1.3C warming, but that number is actually over 2C (> 1.5C by 2100). This is quite a different message than we get from Earth System Models, which suggest committed warming is only ~1.2C. 2/19

This would imply that the 1.5C by 2100 target is effectively impossible, and that long-term warming of >2C would be very difficult to avoid. However, the devil is in the details, and the picture is not quite as dire as it would seem at first glance. 3/19

When we talk about "committed warming" folks are generally talking about one of two scenarios: either constant CO2 and other GHG concentrations (and forcings), or getting all emissions (or just CO2 emissions) down to zero immediately. 4/19

In the first method – constant concentrations – we find that the world warms up another 0.5C or so, as the oceans continue to take up heat as more energy is being trapped by greenhouse gases than is being emitted back to space. Much of this additional warming happens by 2100 5/19

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

It's #FigureFriday, so let's chat about my favorite subject: color palettes 🎨 for climate science visualization! (1/12)

First, why is it important? Put simply: a beautiful figure can communicate your results more effectively than text. It can make a figure more understandable to a public audience. So it is worth it to put care into your figure design. (2/12)


First, if you're plotting up climate model data, especially anomalies, I highly recommend Cynthia Brewer's palettes on ColorBrewer. BrBG is my go-to for precip anomalies, and RdBu is a natural for temperature. (3/12)

The sequential palettes are also great if you've got data going in one direction. Here's the Brewer "blues" at work for a figure showing LGM T change. (4/12)


But what about line graphs? If you are paleoclimatologist like me, you are probably plotting a bunch of squiggly lines. For this, I suggest designing a palette for your *entire paper* ahead on time, and then plot stuff in this palette in every figure. (5/12)

Just as no amount of flat temperature data would dissuade the climate cult, so no amount of flat (or even negative!) data on mask effectiveness will shake the faith of the Church of Covid. Beautiful Theories cannot be disproven by mere information.

The "Covid emergency" will never be over. It will mutate and seek out new missions when this particular virus threat abates, repurposing its funding and clinging to its power. They're already talking up the "next pandemic" and how we must forever remain at DEFCON 2 to be ready.

Masks are now a visible and tangible symbol of an entire agenda. Its champions will use every means possible to force you to wear them forever, including corporate pressure, their new favorite tool. Expect commercial mask requirements to linger, especially big corporations.

True believers, meanwhile, will wear their masks with grim determination and scowl ostentatiously at everyone who refuses to join them. It's a new virtue signal that will not go away any time soon. Mask scolding is a quick, easy, heady power rush.

All the while, studies will keep rolling out that masks don't help, and might even hurt. That was fairly common medical knowledge before the pandemic began, but it was aggressively suppressed when masks became a political symbol, and a totem for people desperate to DO SOMETHING.

MEENAKSHI AMMAN, MADURAI (TN)
#bharatmandir #navratri2021

A paadal Petra sthalam where Shiva took the form of Sundareswarar (the handsome one) and married Devi Parvati (Meenakshi).
Devi is also known by the name Angayarkanni (mother with the beautiful fish eyes).
@GunduHuDuGa


Devi Meenakshi emerged from yagna fire as a 3 year old girl when Pandyan King Malayadwaja and Kanchanamalai were praying for a child.
It is said that Devi was born with three breasts and there was a prophesy that her superfluous breast would melt away when she met her husband.


Devi ruled over Madurai and captured Indralok. She went on to capture Kailasha. When she saw Shiva, her 3rd breast disappeared and she realised that Shiva would be her consort.
The divine marriage was attended by all Devas and Sri Vishnu (as her brother) gave her hand to Shiva.


It is said that Indra found a swayambhu lingam at Kadamba Vanam. He placed it in Madurai where the kshetram stands. Here, Shiva is seen on the vehicle of Indra.
The Golden Lotus Tank is said to be the place where a golden lotus blossomed for the puja performed by Indra.


The Meenakshi Thirukalyanam festival is celebrated in the Chithirai month to mark the divine marriage of Meenakshi Amman. The festival includes a procession where Meenakshi and Sundareshwara travel in a chariot and Sri Vishnu gives away his sister in marriage to Shiva.

A thread on how absurd the UK is on transgender issues and how the UK got so transphobic

In 2015 Parliament held an inquiry looking into the state of Transgender equality. Trans people of all stripes outlined many different problems across many, many different areas.

As a result Parliament created a list of recommendations including legal recognition for non binary people, gender recognition act reform, allowing 16 year olds to change their legal gender and reform of NHS gender identity services.

The government under Theresa May ignored everything that was recommended except for Gender recognition act reform. This act came into law in 2003 and gave trans men and women (but not non-binary people) the ability to legally change their gender on their birth certificates.

The process at that time to change your birth certificate under the GRA was to make an application to a panel of cisgender people who would decide if you were sufficiently trans based on your payslips, photo ID and bank statements. You would not get the option to speak to them.

(Also this process cost £140 which is just a tax on being trans)

I've spoken to 1,500+ people about remote work in the last 9 months

A few predictions of what is likely to emerge before 2030

[ a thread ] 💻🏠🌍

🚜 Rural Living: World-class people will move to smaller cities, have a lower cost of living & higher quality of life

These regions must innovate quickly to attract that wealth. Better schools, faster internet connections are a must

⏰Asynchronous Work: Offices are instantaneous gratification distraction factories where synchronous work makes it impossible to get stuff done

Tools that enable asynchronous work are the most important thing globally remote teams need. A lot of startups will try to tackle this

⚽️Hobbie Renaissance: Remote working will lead to a rise in people participating in hobbies and activities which link them to people in their local community

This will lead to deeper, more meaningful relationships which overcome societal issues of loneliness and issolation

🌍Diversity & Inclusion: The most diverse and inclusive teams in history will emerge rapidly

Companies who embrace it have a first-mover advantage to attract great talent globally. Companies who don't will lose their best people to their biggest competitors

So, you’re a writer and you’re worried about writing outside your immediate experiences and identities.

Here is the thread of practical advice for you.

EXAMINE YOUR MOTIVES. Why do you want to write this?

Are you trying to solve racism/sexism/colonialism with your work?

As writers we love stories about heroic writers whose work has changed the world. And as such we like to look to our own writing to solve societal problems.

And I understand this completely, not the least because I’ve felt the pull.

But if you’re looking to play saviour with your words, it is unlikely that you will do the marginalised people you are trying to save justice.

And I understand this very often comes from place of good intentions, but there is a reason that most of the moralising plays written by white abolitionists are deeply uncomfortable to read.

It is incredibly easy for works looking to play saviour to become patronising or traffic in simplistic stereotypes that ultimately hurt the people they are looking to rescue.

LING PURANA: IMPORTANCE AND CHARACTERISTICS

Reading Ling Purana provides bhog and moksha to the reader and listeners. It is about Shiva's sermon to Brahma when Shiva entered the Agni Ling and preached about Dharma sidhhi through the stories of Agni Kalp.


Vyasji divided this into two parts. This book is different from others and has eleven thousand shlokas which depict the glory of Shiva. This Puran is the summary about importance of Tridev.
It starts first with a questions. Then it describes the Shrishti in brief.

Then there is description of Yog and Kalp. Next is the evolution of Ling and its puja Vidhi. It consists of dialogue between Sanat Kumar and Shail etc. It also mentions the character of Dadhichi, the dharma representation of that yug, Bhuvan kosh description,

Chandravansh and Surya vansh. Next there is elaborate description of Shrishti, story of Tripur, Ling and Pashu Paash vimoksha, Vrats for Shiva, Discipline, Repentance, Arisht, description of Shri Shail. Next is the story of Andhakasur, Varah, Narsingh,

k¡lling of Jalandhar, Shiv sahastra naam, story of Daksha's yagya and its destruction, killing of Madan and marriage of Parvati.

Next is Vinayak katha, Shiv tandav, Ambrish katha and Upmanyu .
