#PlacesOfWorshipAct 1991 में पास हुआ, जिसके अनुसार हिंदू अपने छीने गए मंदिरों पर दावा करके वापिस नहीं ले सकते!

उसी देश में, उसी संसद ने, उसी सत्ता ने, 1995 में #WaqfAct पास किया जिसके अनुसार #WaqfBoard/मुसलमान मस्जिद, दरगाह या कब्रिस्तान की दावे की भूमि को ही नहीं,

किसी भी भूमि को अपना घोषित कर सकते हैं, इसके बाद अपील भी उन्हीं से करनी होगी, निर्णय भी उन्हीं का होगा।

उस समय देश में 80% हिंदू थे, संसद में 95% सांसद हिंदू थे, कानून मंत्रालय जो नए ऐक्ट तैयार करता है उसमें 95% प्रतिशत हिंदू थे, फिर भी ये दोनों राक्षसी कानून पास हुए।

2/5
हम हिंदू, वास्तविकता में जीवन से क्या चाहते क्या हैं?

What are our desires, expectations from life?

भूमि- वो मुसलमान छीन रहे हैं!
लड़कियाँ- वो मुसलमान छीन रहे हैं!
धन- वो मुसलमान हमसे ही लूट/कमा रहे हैं…..

और बचा क्या ??

In March, a team of researchers published a provocative new idea: Tyrannosaurus rex, the most famous dinosaur, wasn't one dinosaur at all, but three separate species that were so similar all prior researchers had missed their differences.
link.springer.com/article/10.100…

2/16
The two new species were named Tyrannosaurus imperator (the tyrant lizard emperor*) and Tyrannosaurus regina (the tyrant lizard queen).

*Imperator is actually Latin for "commander", but was a title given to the Roman emperors, and became the origin of our word "emperor"

Nova entrega del gran Phil 🧶 sobre l’#Arqueologia!
Recordeu que els dies 9 i 10 de Juliol la @Vineaetalni 2022 organitza el primer Taller d’Arqueologia!

Al capítol 1 us vam explicar la importància dels estrats per a poder fer una bona excavació arqueològica.
Avui al capítol 2.1 passem a una altra pregunta: què apareix a un #jaciment arqueològic #romà 🏺?

Bàsicament apareixen dos grans tipus de restes: les mòbils, majoritàriament els objectes 🏺; i les immòbils, és a dir, les #estructures 🏛️.
Les restes immòbils són les més fàcils de trobar, perquè es tracta dels murs, les #columnes, els paviments i la resta d’elements constructius dels #edificis. Per les seves dimensions no solen passar desapercebudes…

Thread alert!🧵 Myself and @E3G colleagues had been toying around with writing a blog summarising the impacts of the #Russia/Ukraine crisis on the global #coal-to-clean transition, when it was pointed out that any such blog would be outdated and irrelevant within days.
Instead, we’ve decided to pull together a regularly updated meta-thread bringing together the sharpest analysis out there. A few caveats to kick things off…
The Russian invasion of #Ukraine is clearly a very fluid situation, and at the centre of it lies a humanitarian crisis of epic proportions. People are dying and lives ruined. This is *not* something to refer to as an ‘opportunity’ (looking at some #climate commentators, here).

Heute hat die .@EU_commission den delegierten Rechtsakt #Taxonomie nahezu unverändert durchgewinkt. #Atomkraft ☢️+ #fossil|es Gas 🔥 sollen als nachhaltige Investition gelten.
Es gab eine interessante Pressekonferenz dazu (Thread 🧵, 14)
Kommissarin @McGuinessEU antwortete eloquent an kritischen Fragen vorbei, spielte offenkundige Gefahren herunter. Betonte andauernd, Atom + Gas seien lt #Taxonomie nur Übergangstechnologien (hab irgendwann aufgehört zu zählen, wie oft „transitional“ fiel) (2)
#Atomkraft sei zwar mit Gefahren behaftet, aber die Betreiber müssten ja Pläne für ein Endlager bis 2050 vorlegen, und die Taxonomie unterstütze auch Investitionen in #AKW Rückbau und Atommüll-Behandlung (3)

@EU_Commission macht Kniefall vor der fossil-atomaren Lobby! Entwurf für #Taxonomie-Anhang zu #Atomkraft und #fossil|em Gas stellt beide als "Übergangstechnologien" dar. Damit entwertet sie Finanztaxonomie als glaubwürdigen Nachhaltigkeitsstandard. (1/7)

Fossiles Gas soll als nachhaltig gelten, wenn vom Kraftwerk nicht mehr als 270 g CO2/kWh emittiert werden und #Methan|schlupf vor Ort vermieden wird. Die Methanemissionen der Vorkette, die bis zu 30% der #Klima|wirkung von Erdgas ausmachen, werden ignoriert. (2/7)
Bei Fernwärme darf Gas andere Brennstoffe ersetzen, wenn "Erneuerbare die Energie nicht effizient bereitstellen können". Keine weiteren Angaben. Bedingung ohne messbare Kriterien = keine Bedingung.
Nicht definierte "low carbon" Gase sollen bis 2035 zum Einsatz kommen (3/7)

New Paper: A 5 million year old #fossil from Melbourne is the oldest evidence of pig-nosed turtles in Australia, marking a substantial shift in their biogeographic history! 🐢 @Monash_Science
@museumsvictoria Thread 1/7

🎨: @BranArtworks
doi.org/10.1002/spp2.1… Image
Meet the pig-nosed turtle: a highly aquatic tropical freshwater turtle, and the only surviving species of carettochelyids.

Native to Northern Territory and New Guinea, with fossils found in the Northern Hemisphere; scientists thought they were recent arrivals to Australia. 2/7 Image
However, this fossil was not only found on the opposite end of the continent, it's also 5 million years old. This suggests that pig-nosed turtles have been in Australia longer than we previously thought. 3/7 Image

We have published an English summary of our hydrogen report: umweltrat.de/SharedDocs/Dow…
 
Key messages:
Hydrogen is necessary for #climateneutrality, but needs to be used in an efficient manner. Only #greenhydrogen produced from #renewable power can be produced sustainably.
Blue hydrogen is currently discussed as a bridging technology. In our opinion, it is not sustainable due to residual GHG emissions, insufficient short-term #CCS capacity and the risk of #fossil infrastructure lock-in. Therefore, it should not receive public subsidies.
Stringent certification is necessary to minimize the environmental footprint and social issues of hydrogen. This is both true for imports and European production.
 
An additionality criterion for renewables can ensure that green hydrogen does indeed reduce carbon emissions.

The teeth of a new species of the hybodont #shark, which belonged to the #Jurassic era, have been discovered for the first time in Jaisalmer, Rajasthan. #Paleontology #Fossil

Details: weather.com/en-IN/india/bi…

(📸: IANS)
The fossils were discovered from the Jurassic rocks in the #Jaisalmer region of #Rajasthan. The rocks are between 160 and 168 million years old.

The crushing teeth represent a new species, named by the research team as 'Strophodusjaisalmerensis'.
The genus Strophodus has been identified for the first time in the Indian sub-continent, and is only the third such record from Asia—the other two being from Japan and Thailand.

#efuels(right) replace fossils without the end-use transformation required by (direct) #electrification(left)
This promises to make combustion technologies and fossil infrastructure part of the climate solution;
yet, shifting the burden to the supply side has limitations…

#Efuels require 2 – 14 times more (renewable) electricity than a direct #electrification (e.g. electric cars are five times more efficient)
Remember, (growing) renewable power capacity is far from fully meeting only today’s electricity demand.

My last PhD paper is (finally) out: bmcecolevol.biomedcentral.com/articles/10.11…
@BMC_series

In this #openaccess jam, we look at the idea of convergent #evolution between the #thylacine and the 'usual suspects' - the #wolf or dog
THREAD > 1/18
One of the most obvious aspects of the thylacine is that they don't really look much like any marsupial living today.
They do, however, look a lot like placental canids (wolves, dogs & relatives).
So much so that they are sometimes known as the 'marsupial wolf'!
🎨: Carl Buell
The resemblance to canids means that the thylacine is a classic example of convergent evolution, where unrelated lineages independently evolve similar features.
Examples are all around: bats & birds, whales & fish, and crab.

Managed #forest landscapes is how big part of the #climate solutions that we need?

Here's some background and some thoughts. /1
Starting with the annual update of net sink in Swedish forests: A continued large net uptake by trees and soil (35 Mt CO2/yr)

This is the enduring effect of long-term investments in the forest-based sector. But what about the rest of the world? /2

slu.se/ew-nyheter/202…
At EU level the net forest sink is 400 Mt CO2/yr which corresponds to 10% of EU emissions. Forests are actively managed and #wood harvest is well below (2/3) of the growth.

But this is not the full story of climate solutions from EU managed forests. /3

#Fossil of 9,000 Years Old Female Hunter Challenge Misguided Assumptions Around Gender Roles in Early Humans

weather.com/en-IN/india/sc…

(📸: Matthew Verdolivo, UC Davis IET Academic Technology Services)
Historical evidence suggests that almost all early humans were hunters and gatherers thousands of years ago before we gradually transformed into agricultural societies.
Now, an unexpected new discovery is set to turn this age-old belief on its head! Newly discovered fossil of a 9,000 years old female hunter from a burial site in the Andes Mountains of South America has intrigued researchers and has made them challenge pre-existing belief.

March 17 2020: "#Gates has proved there is a far easier path to political power, one that allows unelected billionaires to shape public policy in ways that almost always generate favorable headlines: #charity."
"Describing his approach by turns as "creative capitalism" and “catalytic philanthropy," Gates oversaw a shift at his foundation to leverage "all the tools of #capitalism" to "connect the promise of #philanthropy with the power of private enterprise."

#Microsoft #Pharma
The #Gates Foundation has made over the last two decades, ...close to $2 billion in tax-deductible charitable donations to private companies—including some of the largest businesses in the world, such as #GlaxoSmithKline, #Unilever, #IBM, & #NBC Universal #Media."

It’s #Croctober, so that means I’ll be featuring croc-relatives using the hashtag #AtoZcrocs. Follow along this month for a deep dive into how weird croc #evolution really got.
A is for Anatosuchus, a notosuchian from the Cretaceous of Niger. It’s name means “duck-crocodile,” for it’s oddly flared snout. #Croctober #AtoZcrocs #fossils

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… skeleton of Anatosuchus, flared snout to the left, body out to the right, missing most of its tailArtist's reconstruction of Anatosuchus in an upright posture, duck-like snout gaping to show off flared shape
Anatosuchus’ upright limb posture and funky snout might have helped it wade in the shallows and root around for small prey. #Croctober #AtoZcrocs #fossils

(1) While there's ongoing growth in #renewables, share of fossil fuels still at ~80%

(2) Share of #renewables is highest (26%) in the power sector, which only accounts for 17% of global final energy consumption

(3) Stunning to see how the overall picture looked like ~10 yrs earlier, in the 2007 @REN21 report.
Shares of fossil fuels, nuclear and #renewables were roughly the same as in 2019 report, since global energy demand has ben growing siginificantly
