@ScientificData We provide estimates of the #warming caused by historical #emissions of #CO2, #CH4 and #N2O by 226 countries, for every year since 1850.
National warming contributions are further split into #fossil or #land use, land use change and #forestry (LULUCF) sources.
National warming contributions are further split into #fossil or #land use, land use change and #forestry (LULUCF) sources.
@ScientificData The top contributors to #warming up to 2021, through #emissions of all three gases since 1850, were:
USA: 0.28°C / 17% of the warming caused by all global emissions
China: 0.20°C / 12%
Russia: 0.10°C / 6%
Brazil & India: 0.08°C / 5%
🇮🇩 , 🇩🇪 , 🇬🇧 , 🇯🇵 , 🇨🇦 : 0.03-0.05°C each

It's a story of persistent high global #CO2 emissions, but with some hints (and some hope!) that *total* human #emissions are levelling off.

Heute hat das @FraunhoferISI eine interessante Studie veröffentlicht: Inwiefern sind die derzeit geplanten #LNG-Terminals zum Import von #fossil|em #Erdgas wirklich für #Wasserstoff oder #Ammoniak geeignet? Eins ist klar: Sie "Hydrogen Ready" zu nennen ist Augenwischerei. 1/x
Die Studie stellt klar: #LNG, #Ammoniak und #Wasserstoff haben unterschiedliche physikalische Eigenschaften. Damit sind auch die Anforderungen an die Import-Infrastruktur verschieden. H2 müsste in flüssiger Form (LH2) importiert werden, was weitere Probleme mit sich bringt.
Um z. B. später für #LH2 geeinget zu sein müssten gleich in der Design-Phase des Terminals bestimmte Stahlarten genutzt werden. Selbst dann würden für eine Umrüstung wohl ca. 50 % der Investmentkosten erneut anfallen.

At present, #India classifies #geodiversity in different ways.
Here are some broad categories that may serve us well:
Geo-monuments, #fossil sites, archaeological sites, and landscapes - we've listed many sites under the first 3 categories, yet we need to do SO much more.

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

The #Cambrian Explosion marks the first appearance of many animal phyla in the #fossil record, but just how radical was it? I'm starting a new #FossilFriday thread where I post Cambrian fossil representatives of one phylum per week. Join me on this trek across the tree of life
Let's begin with #Annelida. In the #Cambrian these come mainly from deposits of exceptional preservation. Polychaetes and sipunculids, including species with potential affinities to living families, are represented.

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)

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
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.

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'!

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.

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.
