New paper: Review and Analysis of Strategies for Reducing Life Cycle GHG Emissions of Residential Buildings in Humid
Subtropical and Tropical Climates by Daniel Satola et al. 2021 - A Thread (1/9)

We reviewed more than 70 building LCA studies in climate regions common in the Global South, studying building cases from Asia, Oceania, South America and North America. We conduct detailed analyses ...
(2/9)

...based on a final sample of 36 building cases which were fit for harmonization of results. Therein, life cycle GHG emissions show a wide range of 491 to 4811 kgCO2eq/m2. To understand more: First, how structural material choice is influencing emissions...
(3/9)

...we study both embodied and life cycle GHG emission in relation to primary materials used in the building structure. This shows lowest embodied emissions with wood as structural material, and potentially low emissions from use of concrete (non-reinforced). Second,... (4/9)

...we investigate specific design strategies applied in the different cases to analyse their potential for reducing operational and/or embodied GHG emissions. Substantial embodied GHG emissions reduction can be achieved by use of local materials, ... (5/9)

... wood-based structures and extended service life, among other strategies.
Strongest potential for reducing operational emissions is use of photovoltaics, thermal improvement of building envelope, among other strategies. PV shows trade-offs with embodied emissions. (6/9)

Energy and grid electricity mixes have strong influence as well. Find more on energy mixes and other relevant aspects in the paper. Below the full table of building design strategies we investigated and their respective reduction potential. Thanks for your interest!

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

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.

Stump Up For Trees
@Stumpupfortrees

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;

It was a dark and stormy night...

(I’ve always wanted to tweet that) But seriously, there was a tropical storm when a group of people gathered in the woods.

If they were white, we’d call them “founding fathers” but they were slaves who were about to change the world

A thread

Holup. I ain't learned about this in school. What was this??
— Drunk Tweets, Inc - Mask it or Casket (@DrunkTweetsInc) January 1, 2021

Voudou priestess Cecile Fatiman danced with a knife. Then she split a pig and everyone drank the pig’s blood from a wooden bowl while enslaved priest Cutty Boukman prayed:

“The god who created the earth; who created the sun that gives us light. The god who holds up the ocean;

who makes the thunder roar. Our god who has ears to hear. You who are hidden in the clouds, who watch us from where you are. You see all that the white has made us suffer. The white man’s god asks him to commit crimes. But the god within us wants to do good...

It’s He who will direct our arms and bring us the victory. It’s He who will assist us. We all should throw away the image of the white men’s god who is so pitiless. Listen to the voice for liberty that speaks in all our hearts.”

Then , the meeting adjourned & everyone went home.

A week later, on Aug. 21 1791, it began.

In one week, 1800 plantations on the Island of St. Domingue would be burned to the ground and 1,000 white enslavers would be dead.

The shit had finally hit the fan.

Time for a Thread🧵On yesterday’s “F&O Pe Charcha - Diary Of An Option Seller” with @Mitesh_Engr by @Paytm Money

Why Gain/loss ratio is important that the batting average
• More than the Win Loss ratio check the total Gain /loss ratio
• If your avg loss is 1% and avg gain is +5% then even if you are losing in 7 positions and winning in 3 out of 10 still you will be net profitable

Treat Trading as a business:
• Stick to a single strategy. Eg: A restaurateur usually wouldn’t be changing his recipe on a daily basis
• Mitesh Sir only works on BO or BD strategy, as he is a versatile trader

• Any trader should atleast experience 3 scenarios i.e. bull, bear & consolidation
• Target 4% per month i.e. 48% p.a.
• Option buying requires skill, everyday there wont be huge momentum, so buying options won’t yield good results, but high chances of falling into a bad habit

Stock Selection:
• In F&O segment there are ~150 stocks
• Not everyday all stocks will move
• Only 5-7 stocks move upside or downside
• Focus only these momentum stocks
• Check which one is moving
• Range BO/BD never disappoints. BO/BD from a rectangle (consolidation)

Joanna Cherry:"Alex Salmond secured a concession that nothing in Scotland Act would preclude the people of Scotland from subsequently choosing an independent future. This is recorded in Hansard during second reading of Referendums (Scotland & Wales) Bill, May 21, 1997."

Donald Dewar said: “I should be the last to challenge the sovereignty of the people, or deny them the right to opt for any solution to the constitutional question they wished. For example, if they want to go for independence, I see no reason why they should not do so." JC

"In same debate Alex Salmond went on to emphasise that “… the Claim of Right referred to sovereign right of the Scottish people to determine a form of Govt best suited to their needs. It did not suggest sovereignty resides with English Members of Parliament." Joanna Cherry

Joanna Cherry: "Donald Dewar articulated the democratic norm later enshrined in the Edinburgh Agreement. His concession laid the foundation for the 2014 referendum in recognising the rights of Scots to choose whether to remain part of our voluntary union with England."

"I am wholly in agreement with view that we must find a legal & constitutional way to demonstrate that public opinion in Scotland has changed since 2014 referendum, in order for our independence to be internationally recognised & therefore meaningful." Joanna Cherry

(THREAD) The Whitaker scandal is deepening, as it becomes clear that Sessions' Russia recusal was a coordinated sham and his firing an act of obstruction—and that his replacement is a White House plant inside the Mueller probe. I hope you'll retweet and read on for more details.

1/ From 2014-17 Whitaker worked for World Patent Marketing—which during his tenure defrauded consumers out of $26 million and was successfully prosecuted by the feds. His involvement in the scam confirmed he had loose morals and that the feds would never want to employ him again.

2/ Despite the seeming impossibility of a man with Whitaker's background getting a job at Justice ever again—he'd been found to have used his former title as a US attorney to fraudulently threaten consumers with valid complaints with criminal penalties—Whitaker found an opening.

3/ Within 60 days of parachuting out of World Patent Marketing as it was being fined $26 million by the feds, Whitaker was working for CNN and telling a fellow attorney panelist that his purpose in working for CNN was to get noticed by one man—Donald Trump—and thereby get a job.

4/ Whitaker spent his time at CNN making ludicrous statements about the Mueller probe: there was no obstruction or collusion, he said; Mueller had no authority to look into any aspect of Trump's finances or to subpoena him, he said. All the while, he hoped Trump was watching him.

SRI KUMARIAMMAN, KANYAKUMARI (TN)
#bharatmandir #navratri2021

Created by Maharshi Parasurama and also one among the 108 Shakthi Peethas in the world. The name Kanyakumari stands for Kanya(Virgin) and Kumari(girl).
Devi took this form to vanquish the demon Banasura
@GunduHuDuGa

Once, Banasura(grand son of Mahabali) obtained a boon from Shiva that he could be vanquished only by a virgin.
So, Devi took the form of a kumari and started meditating with the desire to marry Shiva at Suchindram.
Pleased Shiva fixed the midnight hour for marriage with Devi.

Devarshi Narada knew that the marriage would end the chance of killing Banasura. So, he assumed the form of a cock and crowed. Shiva returned back to Suchindram thinking that it was dawn.
Angered, Devi cursed that all food and articles meant for wedding turn into sand and shells

When Banasura heard about Devi’s beauty, he tried to take her by force. Devi, then, killed him and granted the wish of Devas to remain there always protecting them.
The murti of Devi stands with a rosary in hand. Her diamond nose-ring is said to be visible even from the sea.

Once an ancient mariner mistook it for a lighthouse and sailing towards it, his ship wrecked upon the Kanya Kumari rocks. In order to prevent such a tragedy from happening again, the eastern door of the shrine is opened only on five special occasions throughout the year.

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/
