**Bar Chart Race for CO2**

The changing ranks of the 10 largest CO2 emitters in the world since 1850.

Fascinating to see nations rise, fall & rise again in their yearly emissions*

See how the UK dominates the C19th & US the 20th.

Then watch China surge ahead after 2005…
Huge thanks to @jburnmurdoch for making his "bar chart race" code easy to use & publicly available:

Here's my "fork":

I'm sure John / others could suggest lots of improvements eg to avoid the many decimal places on 1st frame…
Credit for data goes to CDIAC (through 2014) and the Global Carbon Project (through 2017).

CDIAC:

GCP:

*This one's for the data pedants:

It's territorial CO2 emissions including fossil fuels and cement, but not land use and forestry, hence why likes of Brazil and Indonesia don't feature. Also excludes international aviation and shipping, imports and bioenergy.
We (@CarbonBrief) have written extensively about all of those other issues.

Some recent articles:

Imported CO2:

Aviation:

Shipping:

Read the summary attached (or at the link below) if you're interested in how there can be CO2 estimates from 1850 (they actually go even further back, to 1750, for some countries).

It's based on historical records of the trade in fossil fuels.

Finally, I thought about making variants for per capita emissions and/or cumulative emissions over time but you have to start somewhere!

NEW

Letter from @theCCCuk to UK transport sec Chris Grayling:

* International aviation needs a climate goal
* Corsia needs "robust rules"
* UK aviation shouldn't rely on offsets
* UK aviation CO2 limit might be too weak

THREAD with details

theccc.org.uk/wp-content/upl…
International aviation sector should set a new long-term climate goal and must ensure "robust rules that deliver genuine emissions reductions" under its Corsia offsetting scheme, the letter says.

theccc.org.uk/wp-content/upl…
CCC letter also says the UK aviation sector (inc its share of intl flights) must actually limit its CO2 emissions, rather than relying on international offsets to mop up the problem.

The Sunday Telegraph has a front page story on HS2 & windfarms.

The paper's editors have written an editorial too: "Hard to imagine a more costly, unattractive combination [continues]".

But it's based on a document that shows renewables could *save consumers money*.

THREAD

1/
Alarm bells started to ring when I saw that the story was written by the paper's "Sunday political editor".

It cites "experts" but only quotes two people: a spokesperson for HS2 and anti-wind campaigner John Constable.

🤔

2/
The story says HS2 is considering signing contracts to power the high speed rail line with renewables. Shocking.

Quoting those "experts" (apparently John Constable counts as more than one person), it says this would amount to a "hidden subsidy".

So what's actually going on?

Greg Clark, sec of state for Business, Energy & Ind Strategy, in statement to Parliament re Wylfa:

"Economics of energy market have changed significantly…offshore wind dramatically down…almost no subsidy"
Positive cost trend seen for renewables not seen for nuclear, says Clark:

Made task of attracting private finance to new nuclear more challenging.

But Govt continues to believe in need for diversity of sources. Nuclear has impt role to play,
Clark says Govt was willing to consider taking 1/3 equity stake, alongside others, and was willing to provide *all* agreed debt financing

Plus CfD at up to £75/MWh

[Wow]

New project:

A “Bar Chart Race” animation showing the changing ranks of the 10 biggest cities in the world since 1500.

Fascinating to watch giant cities vanish after falling in conquests, and amazing that three UK cities were in the top 8 in the late 1800s.
Notes:
• Full code for the animation here on @observablehq observablehq.com/@johnburnmurdo…
• I’ve tried to build this in a fairly reproducible way, such that you give it a dataset containing entity, year, value, and it does the rest
• Feedback welcome!
#dataviz
Data:
• Pre-1900 I’m using @nasaearthdata’s “Historical Urban Population, 3700 BC  to  2000” sedac.ciesin.columbia.edu/data/set/urban…
• Post-1900 it’s that merged with data from the UN and Demographia on urban agglomerations data.london.gov.uk/dataset/global…

#Khashoggi Case Thread: I am going to ‘pin’ this post to use it as an ‘Info Thread’ on the #Khashoggi Case. I am in #Turkey. I’ve been following the case closely and with access to sources & experts here. This is a very ‘sensitive’ criminal case due to ‘Diplomatic Booby Traps’!!!
The Evidence Obtained Outside Cameras will not show any evidence of ‘tempering’ but other than license plates of dozens of diplomatic cars (Many with tinted windows-large trunks) with related time stamp, drivers Info, model/year: Nothing.
#Turkish Intel-Investigative Bodies also have the list of all Diplomatic & Private Saudi & “other significant’ Planes in #Turkey for the period of ‘interest.’ Many of the Target airports have their own security cameras & related evidence.

1) I'm not sure how to make people remember or care that 15 years ago the United States invaded Iraq, setting off a war that continues to this day, with several hundred thousand Iraqis dead, millions turned into refugees. I covered the invasion for the New York Times Magazine.
2) Though I'm a writer, I shot photos during the invasion as I drove a rented Hyundai SUV from Kuwait into Iraq via Safwan, then up the spine of the country to Nasiriya, Diwaniya, Hilla, Kut and finally Baghdad. Here's the Hyundai on March 19, 2003. It's clean--that will change
3) The photographer I worked with, Laurent vander Stockt, drove his own SUV. After several failed attempts to get into Iraq, one time turned back at gunpoint by U.S. soldiers, we finally got through, via what we guessed was a minefield (I followed Lauren tracks). Here's Laurent.

Critically ill Russian national is 66yo Sergei Skripal, former intel colonel/double agent granted refuge in UK after a 2010 "spy swap" between US & Russia. He and a woman were apparently poisoned in/near Salisbury shopping center. bbc.in/2D2oj7X
Ex-Russian spy & daughter 'poisoned' in UK sparks fears of another Kremlin-backed hit. Investigators scrambling to identify the chemical used. Skripal feared for his life after his wife died in a car crash & his son was killed in a road incident.. thesun.co.uk/news/5733372/s…
UK warns Kremlin over poisoning of ex-spy Skripal & his daughter. Recalling Litvinenko murder, FM Johnson said UK was "in the lead across the world" in trying to counteract a "host of malign activity" by Russia.

Skripal's brother, son & wife have been killed in the last 2 year.
