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the #Russia/Ukraine crisis on the global #coal-to-clean transition, when it was pointed out that any such blog would be outdated and irrelevant within days.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… 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:…
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


(📸: 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.

#Climate needs #electrification AND #hydrogen.
Both compete for #renewableelectricity, policy and infrastructure support. Policy makers have to take decisions, secure expectations, avoid further fossil lock-in
Our paper offers guidance.

#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.
(no regret: #renewableexpansion)

What is the @Greenpeace position on #fossil gas ? We know that they are against #nuclear power, but if that had to choose, will they first prefer to phase out of #fossil fuels or #nuclear power ?
Let's find out!
Have a look to this report titled « Silent Killers – Why Europe must replace coal power with green energy » and published in 400 ppm (2013)… Image
The document aims at explaining that 300 plants in EU burn #coal to produce #electricity, killing prematurely 22000 people every year while being the largest source of the carbon dioxide (CO2) emissions Image

My last PhD paper is (finally) out:…

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…
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…

(📸: 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:… 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

📸 Sereno and Larsson, 2009:… Photographs of Anatosuchus' skull in dorsal, ventral, and lateral views, snout flares out like a duck bill, but is filled with relatively small teethLine drawing interpretation of the skull shown in similar views as the photographs, snout flares out like a duck bill, but is filled with relatively small teeth

A couple of weeks back I found what I initially thought was petrified wood while hiking to a fishing spot on the North Saskatchewan River (NSR). Turns out it was a dinosaur bone. Here is a thread about my experience and what I learnt. #fossil #dinosaur #alberta Image
It started with a great day of fishing. The NSR has been pretty high all season and with the start of fall fishing upon us I decided to hike up to a spot where an island forces the river into a small channel. At the end of this channel is a somewhat steep cliff bank Image
On my way back from fishing I crossed under this bank. Some rocks and a section of the bank had fallen down recently and I had to navigate over them. As I crossed over these rocks I noticed something that looked like a clay pipe. White with a bit of a curve to it.

"A team of scientists on Wednesday reported that the #fossil belonged to a 160,000-year-old #Denisovan, a member of a lineage of mysterious, #Neanderthal-like humans that disappeared about 50,000 years ago."… #Sapiens #Tibet
1. "The new fossil demonstrates that #Denisovans were remarkably hardy, able to endure harsh conditions on the Tibetan plateau, at an elevation of 10,700 feet, with only simple stone tools."
2. "The find also suggests that these #Denisovans may have evolved genetic adaptations to high altitudes, and that living #Tibetans may have inherited those genes thanks to interbreeding between Denisovans and modern humans in prehistoric times."

This past Friday marked 33 years since the #Chernobyl disaster. The podcast Today in Focus with @GuardianAnushka from @guardian chose to mark the occasion by uncritically reporting on the extraordinary claims of @katebrownumbc about the health impacts of the disaster. Thread 👇
@GuardianAnushka @guardian @katebrownumbc 1. It is said that "extraordinary claims require extraordinary evidence" but @guardian now joins @sciencemagazine, @nature, @TheEconomist, @thesundaytimes and others in providing a platform for Brown's radical claims with a remarkable lack of critique.…
@GuardianAnushka @guardian @katebrownumbc @sciencemagazine @nature @TheEconomist @thesundaytimes 2. Historian @katebrownumbc alleges that several intergovernmental and non-governmental organisations such as @UN, @WHO, @IAEA, @iaeaorg, @RedCrossEU and the UNSCEAR have conspired to cover up tens of thousands or hundreds of thousands of casualties resulting from the accident.

#climate twitter! I want to donate 10% of my 2019 income where it will do the most good to reduce emissions. Would love to hear your take on the most effective orgs (in this thread or private DM). Thanks! Ping @drvox @KHayhoe @Fisher_DanaR @AmyAHarder @LeehiYona @EricHolthaus
As I replied to @EricHolthaus- I'm aware of and inspired by @givingwhatwecan & @GiveWell work on global health/poverty; I personally want to support climate mitigation. I realize there's no one right answer, depends on theory of change etc; curious to hear different perspectives.
Esp. in climate arena where impact could be on different possible levels (eg X tons avoided from cookstoves vs Y tons #fossil CO2 kept in the ground vs systemic political or economic change)- curious to hear diverse range of theory of change or evidence of effectiveness.
