Today is the @UN

I want to hear from dieters.

Studies are full of people who go on a diet, lose weight, and then regain.

I have done this. If you have, too, I want to hear your story. What happened?

I'm writing about how we can make this stop.

DMs open.

RTs appreciated. twitter.com/TamarHaspel/status

People are still tweeting about the NYT's piece on the SPARC nuclear release, so as a fusion PhD student I'm going to explain what it is and isn't...

"Europe’s cumulative excess mortality rate from March to July is 28% lower than the US rate, contradicting the Trump administration’s claim that Europe’s rate is 33% higher.”

This was very sad to watch.
What stood out most for me was that the US President told the people of his country that they cannot trust the election process in his country. And overall that he has an extremely negative view of his country. twitter.com/MaxCRoser/status/1

.@nature has invited me to write up the experience of how my tweet turned into the Oxford on its Career Column @NatureCareers: it’s been a lesson of utilising the power of swarm intelligence via social media to create a public good.

Re @yourkleinod This is about 'Wright's law', which describes the relationship between production and price.

The question whether it is causal link is a big deal cause it means that scaling up production (e.g. through subsidies) is something that has positive externalities (a lower price). twitter.com/MaxCRoser/status/1

For many technologies we see that more production is associated with falling costs.

But is this causal? After all it's possible that we only increase production because costs are falling.

This paper says studies this by an event that is exogenous: WWII.

The world emits around 42 billion tonnes of CO₂ per year.

How much is from fossil fuels, and how much from land use change?

→ 36.6 Gt from fossil fuels (87%)
→ 5.5 Gt from land use change (13%)

Data from @gcarbonproject. Note this is CO₂ only.

The world has reached 1⃣,0⃣0⃣0⃣,0⃣0⃣0⃣ coronavirus deaths.

Here's my take on how that 1m compares to a 'normal year' - with thanks to @OurWorldInData for their excellent resources

Today's update of @OurWorldinData includes the 1,000,000th confirmed death attributed to COVID-19.

Graphs & data are helpful to retrace the story of this pandemic so far, since the first death was confirmed in China on January 9.

Here, the total is broken down by world region:
