Professor Johan Rockström, Director of @PIK_Climate talks about tipping points in this thread.

“West Antarctica has potentially crossed the tipping point. If this is correct we have to revise our projected sealevel rise for this century from roughly 1m to 2m.”

[THREAD 1/5]
When the Arctic tips over, it turns from a cooling system into a heating system.

@jrockstrom explains this using July 2012 as example. The Arctic took up 300 Exajoules of extra energy in just 2 weeks. That is equal to half of the world’s annual energy consumption.

[THREAD 2/5]
Professor Rockström compares the IPCC assessment reports 3, 4 and 5 regarding the estimated risk for crossing “human induced catastrophic tipping points”.

This threshold came down from 4° to 2° over time as the scientific understanding evolved.
What will AR6 bring?

[THREAD 3/5]
Professor Rockström calculates the risk for a 6° temperature rise in this century according to the IPCC AR5. He calls it an “uninhabitable planet”.

Note that the basis for this calculation is the total concentration of all greenhouse gases incl CH4, N2O + aerosols.

These are excerpts from Prof. Rockström‘s online lecture on planetary boundaries accessible free of charge on edx:

I recommend this presentation by Johan Rockström, if you like to see more 👇

This is the graph shown in this clip.
Thanks to @jrockstrom.
You could also read the risk for 4°C from this chart which is a staggering 7%, based on the atmospheric concentration of greenhouse gases in 2014.

If one of the world's most respected climate scientists has to explain the impacts of the #ClimateCrisis in just 2 minutes, it sounds like that.👇That's the essence.

#TellTheTruth #WeDontHaveTime

[THREAD 1/2]
This was Prof. Will Steffen in Canberra, May 2016.

If you can take a few more minutes, you should really have a look at this longer presentation by Will Steffen. This is one of the clearest illustrations of the climate crisis that I know.👇



[THREAD 2/2]
To all of you who think, we might have time to stop global warming at 2.5°C: Main message here is, that tipping cascades could turn #ClimateChange into an express lift. If we miss our stop at somewhat about 2°C, we might be rushing straight towards 4°C, 5°C or more. #TellTheTruth

A video thread about Roger Hallam, one of the founders of #ExtinctionRebellion.👇

Maybe it’s time for other forms of peaceful protest.

First few videos cover the #ClimateCrisis. Climate scientist Prof. Jason Box supports Hallam's claims.👇


THREAD [1/19]
Roger Hallam claims that the #ClimateCrisis is not too complicated overall. Just focus on the killer facts:
"Like going to the doctor. You got something with your foot and something complicated with your arm but you’ve also got lung cancer. That’s the killer fact."

[THREAD 2/19]
Roger Hallam, Co-founder of @ExtinctionR, calls the #ParisAgreement "the biggest mass delusion in the history of humanity because it’s got this lie, that we have to stay below 2°C. The simple scientific fact of the matter is: 2°C is already locked in."

You can literally see how @GretaThunberg can’t understand how the chairman of the committee on climate change can ask her such a stupid question:

“Why should we listen to the science?”

This is from today’s testimony in Congress by four young climate activists.

[THREAD 1/11]
This is @Jamie_Margolin with one of her many great statements today:

"Right now it’s like members of government and some corporations are actively pointing a gun at children’s futures. And this is horrifying and it feels like a betrayal.”

[THREAD 2/11]
This is @BenjiBacker speaking in front of the committee on climate change of the US Congress:

“There is actually a lot of opportunity here, that we have time. Science says so.”

To all: Don’t be mistaken here. He is wrong. We don’t have time!

Lots of Netanyahu defenders upset with me for saying that a prime minister of a state founded on ethnic cleaning, who engages today in a form of ethnic cleansing, is warning others against ethnic cleansing. So here's a quick #thread on some basic facts for the pearl-clutchers:
1/
Lots of Israelis who get offended by the term "ethnic cleansing" are fine with it if you replace it with a softer term like "transfer", e.g."Nearly half of Jewish Israelis agree that Arabs should be expelled or transferred from Israel" - 2016 Pew poll2/timesofisrael.com/plurality-of-j…
Israeli historian Professor Ilan Pappé wrote an entire book called "The Ethnic Cleansing of Palestine" in 2006, on the events of 1948, which was described as an "important" account and a "major intervention" by British and Israeli academics alike:

RADICAL APPROACH TO XENOPHOBIA: LESSONS FOR AFRIKA

#THREAD

As a postgraduate student of a Marxian Scholar at the @HQ_NDA - Moses E. I. Tedheke Ph.D; Political Economy of African Security is a Course I offer in my Second Semester of Course work.

#SayNoToXenophobia
I’m exposed to the place of economic relations on Africa’s weak defense and security and above all Africa’s economic crises and continental security.

#SayNoToXenophobia
To think that some South Africans claim that other Africans are competing with them on dwindling cum scarce resources is sheer ignorance. I have not verified this claim but it’s necessary we enlighten ourselves and not entertain such thoughts perhaps they exist

#Thread of responses from women in aerodynamics to the question, 'what would you like to see in order for women's career progression in your field to be sustained and better supported?'

Responses incl. career flexibility, mentoring and more women in leadership roles #WomeninSTEM
1. "I think young female engineers need to see more female role models and mentors in my field. Having a visible example of someone that looks like you and is succeeding in their field is important. Having an opportunity to meet with a mentor like that can be very powerful."
2. "I would like to see that any career promotion is based on own merits and value added to the company or the society independently of the gender. I want that women are measured with the same rules as men and are given equal opportunities."

#Thread During #KeralaFloods many of the people lost their crucial documents. It was a big mess to recover these documents since they don't even remember the document no. Hence, Kerala IT department came up with an API architecture to retrieve the documents. (1/n)
The idea was generated jointly by IT secretary M.Sivasankar and KSUM CEO Saji Gopinath. The target was to retrieve the documents by taking the basic inpit values known to the public. It startes working last day (2/n)
Incase of Aadhaar, govt will take your biometrics as the input value to generate E-Aadhaar if one doesn't remember the ID number. This will be pushed into Digilocker account created. Also will get a print out for free of cost. (3/n)
