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!

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/

How dispossession and corporate greed leads to environmental harm, a worked example form modern day Scotland.

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

A brilliant talk that punctures current discourse on climate ambition in Scotland, setting out what's really needed, by @KevinClimate for @ScotClimateCA

📽️ https://t.co/i02FtSkJT8 📽️

Well worth watching. Otherwise, here's a summary thread 👇
1/10

Want scientific assessment of what Scotland should do to achieve Paris Agreement temperature targets? Look to carbon budgets. See that a failure to rapidly reduce emissions will eat up the carbon budget in just a few years, leaving impossible burdens for future generations. 2/10


Are UK emissions down 45% in 30 years? Not when including emissions from aviation & shipping, and imports & exports – then they are only down 10%. Over three decades, we have had reductions of less than 0.5% per year. 3/10


Scotland’s average per person consumption emissions are still double the global average. Scotland’s consumption emissions have not meaningfully reduced in the last 20 years… 4/10


Principles of global equity and justice mean that Scotland’s fair slice of the global carbon budget is just a few hundred million tonnes of CO2, which is less than ten years of Scotland’s emissions at current levels. 5/10

Comparing two environmental regulation

Preventing emissions vs improving water quality,

Which one better?

https://t.co/zLrVNWIPXm


What is the Difference?
We certainly often hear the term better to prevent than cure. Of course, we all agree on that. But what about improving quality, is that better than preventing?

A researcher named Dan Pan tries to compare 2 different regulations on environmental impacts.

One of the regulations is based on environmental quality limits. the other is based on the market, but we will call it improving water quality because it gives reward and punishment on environmental performance.

Preventing Emissions:

• Restrictions or closings of companies that violate environmental quality standards

• Restricted areas must protect their water

• Implementing comprehensive water conservation

• Strengthens water recovery and protection

Improving water quality

Give awards to mayors whose evaluation scores are good, and adequate, whose evaluations are bad. There are several parameters defined in determining water quality such as: COD intensity, water quality, and industrial wastewater standards

The whiteness of this piece on "climate refugees" (corrected link) is deep.

The piece centers the story of Jen and Ryan Cashman, a white couple + their kids who used to live in Paradise, California.


It does include an interview with Dr. @JalonneWNewsome who explains that climate change hits folks of color harder, and they may be less able to move due to fewer economic resources + less willing to move b/c of greater ties to their communities.


After this perfunctory nod to her excellent work, then the reporter (*cough* abuser *cough*) goes on to segue with one of the biggest "yeah, buts" I've ever heard...

"If you have the luxury of choosing where to live and climate change is a factor, here's the formula..."

Thiruvizha Mahadeva Kshetram
#Alappuzha 
#Keralatemples 🚩

Thiruvizha Mahadeva Kshetram is located in Cherthala and it is believed that Prathishta of temple was done by Vilwamangalam Swamy. Paramashiva is Swayambhu here and is worshipped as Kalakandha which means who swallowed


Halahala visham to save the world during Samudra mathanam. 

It is a famous temple where people seek the blessings, for curing the Kaivisham. The poison given by someone to destroy a person is made to vomit here. This is removed by making them vomit the poison by a special


medicine.
The medicine for vomiting is made from a plant near temple by Palodathu family. The milk offered to Bhagwan is mixed with the extracts of the plant.

Story says that once this place was a dense forest, and a woman was looking for the presence of a tortoise in the pond


and the tip of her stick hit the bottom and it started bleeding in the pond. 
Frightened, the lady informed every one and after searching in pond people found Swayambhu Lingam inside the pond. Thus Prathishta was done here.

Om Namah Shivaye

Ahilyabai Holkar was one of India's
greatest women rulers of all time.

Ahilyabai was Born on May 31,1725 in the village of Chondi,Jamkhed distt,Maharashtra to a man named Mankoji Shinde,who was the Patil(Chief) of a village and a member of proud Dhangar Community.


Despite the fact that girls' education was a farther dream in those days, Ahilyabai was homeschooled by her father.
Ahilya didn't belong to any royal family but in a twist of fate she is still remembered as one of the most revered Queen in the history.


While they were living their humdrum lives, one day Malhar Rao Holkar, commander of the Peshwa Bajirao & Lord of the Malwa stopped in Chondi on his way to Pune, where he couldn't help but notice a young 8yrs old Ahilyabai in the temple service feeding the poor & hungry.

He was so impressed by the sheer innocence&beauty with simplicity character of Ahilyabai dat he asked her hand in marriage for his son Khanderao Holkar.Just like that she got married to Khanderao in 1733 at a tender age of 8&became a bride of esteemed Maratha community of Holkars

But destiny had something else in store for her as her husband died in the Battle of Kumbher in 1754 leaving her widow at 29.Distressed Ahilyabai was to commit Sati when her father-in-law Malhar Rao refused to let it happen.

Multiverse is mentioned in several of Hindu Scriptures.

In 1927 came a theory named 'Big Bang' which was a scientific effort to provide some explanation about how our Universe came into existence. It suggested that Universe started as a tiny, hot and dense...


...something that expanded rapidly from the singularity with a big explosion or Big Bang from which formed the galaxies, stars and the rest of the Universe.
However, the science in our Vedas explained these concepts since millennia. Rig Veda mentions Hiranyagarbha and Brahmanda..

...Visphotak which talks about a similar theory.
The concept of Parallel universes may be novel to the modern scientists but it rests very comfortably in ancient Hindu Cosmology. The Puranas are replete with descriptions of many worlds whose inhabitants are ruled by kings in...


...the human plane and Gods in a higher plane. The many Gods in turn belong to many different worlds and planes of existence. At the highest level of hierarchy are the trinity namely Brahma, Vishnu and Mahesha, ruling the divine Kingdoms. Brahma is the creator who dreams...


...the Universe into being, which is maintained by Vishnu. What Humans perceive as reality is in fact the dream of Brahma, misled by matter. Brahman( not to be confused with Brahma) is the ground of all reality & existence. Brahman is uncreated,external, infinite & all-embracing.

So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.


The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.

This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.

The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."

This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.

Nobel prize winning scientist Luc Montagnier asserts that Sars-Cov-2 is man-made and originated from the Wuhan Institute of Virology.

Montagnier did extensive work with the Pasteur Institute in France which was partnered with the Wuhan P4.

Merieux Foundation & the Chinese government have worked together since 1965, and partnered to study emerging pathogens in Africa in 2015.

Their research included "PATHOGENS CARRIED BY BATS" that provoke respiratory diseases.
