The number of confirmed cases has been declining in almost all regions of Spain.

The only two regions where cases are rising are the Balearic and Canary islands.

[source Spanish government here: mscbs.gob.es/profesionales/…]
The government started publishing the positive rate of tests a while ago – that’s very good and I wish all countries would do that.

But as you see the positive rate is still fairly high in many regions so that the true number of cases is likely quite a bit higher.
This is the number of confirmed cases in the whole of Spain and the positive rate in the entire country – both are coming down which suggests that this decline of cases is real and not just due to worsening testing.

But still important to be cautious – several European countries saw a decline of cases in November and are now seeing cases flatlining or rising.

And in the Spanish data a similar very recent change might already be visible for Madrid, Cataluña, or Navarra.

I guess this will be one of the most important maps to watch over the coming months.

Really happy that our page on COVID-19 vaccinations is online on @OurWorldInData: ourworldindata.org/covid-vaccinat…

If you know of official data on vaccinations in other countries please let us know. Image
For data sources we will only include data published on official websites (or in press releases and by social media accounts of national authorities).

Otherwise it won’t be manageable – we’ve seen that when we built the testing database in the last months.

Thank you.
For all you researchers and journalists out there.

The vaccination data is now also available in our daily updated global COVID-19 database managed by our colleague @redouad.

You can download (and check!) all our data here:

Around half the US population says that they are worried to be killed by terrorists.

The annual probability for an American to die in a terrorist attack during this period was 0.000051%

[ourworldindata.org/terrorism]
The countermeasures against terrorism – including the ‘war on terror’ – were extreme:
It cost trillions of dollars, killed tens of thousand of people, made millions to refugees, reduced civil liberties, legitimized intrusions into privacy.

And it failed entirely to reduce fear.
This looks unfortunately like a huge success for the terrorists.

As Scott Atran says “Perhaps never in the history of human conflict have so few people with so few actual means and capabilities frightened so many.”

Just published my new @OurWorldInData post:

• Why did renewables become so cheap so fast?
→ And what can we do to use this global opportunity for green growth?

ourworldindata.org/cheap-renewabl…
Today fossil fuels – coal, oil, and gas – account for 79% of the world’s energy production.

But as this chart shows they have very large negative side effects.
Why is the world relying on power from fossil fuels if they cause so many deaths and such large greenhouse gas emissions? 

Because in the past they were *far cheaper* than other sources of energy.

The European CDC will soon be switching to weekly data and I see several people concerned that this would create problems for Our World in Data and those who rely on data that they obtain via us.

This is not the case. We are well prepared.

Our data manager @redouad summarizes: Image
What the ECDC was pulling off in the last months was really phenomenal.

Very early in the pandemic – when alternative data sources were often extremely bad – the colleagues there woke up at 4 o'clock every morning to bring together reliable data from countries around the world.
We would definitely prefer if the ECDC would continue doing this work, but I very much understand that it needs to come to an end. And it can because there are good alternatives for case and death data available.

Austria has now the highest rate of confirmed cases in the world. And the rate is still increasing.

Testing is very poor (the positive-rate is 22%) so that the true number of cases is much higher.

Austria now decided to implement a stricter lockdown: orf.at/#/stories/3189…
Austria has the highest rate of all countries with a population over a million people.

Andorra currently has a rate of over 1000 per million, but a small place with 76,000 people has obviously very volatile case rates.

Source with data for all countries ourworldindata.org/coronavirus-da…
This curve shows the number of deaths in Austria.

The average over the last week were 40 deaths per day.

How expensive is it to limit global warming to less than 2°C?

The IPCC reports that the median cost to limit warming to less than 2°C corresponds to an annualized reduction of economic growth by 0.06%, relative to a baseline annual growth of 1.6-3%

ipcc.ch/site/assets/up…
If the world economy would grow 1.6% the world economy in 100 years would be 1.016^100=489% the size of today’s economy.

With measures in place to limit warming to 2C, growth would be 0.06% smaller – i.e. 1.54%.
The world economy would then ‘only' be 461% of the size of today.
In case the world economy would grow 3% per year the world economy in 100 years would be 1.03^100=1922% the size of today’s economy.

With measures to limit warming to 2C, growth would be 0.06% smaller – i.e. 2.94%.

The economy would then ‘only' be 1813% the size of today.
