THREAD. (1) We need a debate on how to design stimulus packages to boost economic recovery that doesn't contradict Paris #climate goals but supports them. This thread tries to capture this debate and create a reading list for those interested in it.
(2) I will post articles both in German and English, try to cover many debates in different countries and update the list regularly. Please feel free to DM me to share articles & complement this list!
(3) As we move from debating principles to specific ideas, I hope sharing examples of good (and bad) practice will inform debates in different countries. If you have technical advice/ suggestions, please DM me.

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

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… 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
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
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." nytimes.com/2019/05/01/sci… #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.
