#AirPollution, measured by annual PM2.5--particles finer than a human hair--reduced in bigger cities such as Delhi & Varanasi but increased in smaller cities such as Fatehabad & Moradabad, finds a @CSEINDIA analysis of 26 cities. Follow the thread for insights:

In many cities in the upper Indo-Gangetic plains, avg PM2.5 levels were above 2019 levels. #AirPollution in Fatehabad, in northern Haryana, deteriorated the most, with PM2.5 levels increasing 35% from 2019
The %age of PM2.5 in the coarser PM10--which determines air toxicity--was in the high 40s in Oct & remained so in Nov, averaging 55% in Amritsar, 48% in Chandigarh & 53% in Patna. It reached 64% in Amritsar, 69% in Chandigarh & 62% in Patna during #Diwali2020
#AirPollution reduced the most in Sirsa, 40km from Fatehabad, with a 44% lower avg PM2.5 2020 level vs 2019. This massive variation can’t be attributed to meteorology & has to do with local factors such as stubble burning, Avikal Somvanshi, CSE prog mgr, said in a press release
PM2.5 avg in Nov 2020 was 310% higher in Fatehabad, 104% in Agra and 57% in Kaithal, compared to November 2019
Home to over 600 million, the Gangetic plains host four cities--Kanpur, Faridabad, Gaya and Patna--that were the most polluted in the world in 2018, according to the WHO, we reported in March 2019:

“Today, more than 76% of the population lives in places that do not meet Indian air quality standards,” Sagnik Sey, coordinator of @CERCA_IITD told us in a Nov 2019 interview: https://t.co/4DjtJGbv3l
In India, the PM2.5 average during the 2020 summer & monsoon was lower compared to 2019 due to #COVID19. But reopening of the economy coincided with the onset of winter in India, which trapped #pollution, leading to a rise in PM2.5 in October, the @CSEINDIA analysis notes
In Amritsar, there were 33 days that met the air quality standards in winter 2020 vs 41 in 2019. In Lucknow, there was not a single day that met the air quality standard after October and 19 days of ‘severe’ or ‘worse’ air quality, up from 5 such days in 2019
#Airpollution killed ~116,000 infants in India within the 1st month of birth. More than half of these deaths were due to PM2.5 in outdoor air, we reported in October 2020:

More from Climate change

The UK government's climate advisory body is launching its next carbon budget: basically, outlining what the UK can emit between 2033 and 2037. It's a big deal - launch video starting right now.
Watch along:


Will tweet along snippets. Pretty relevant to...............everything, really. #UKCarbonBudget

"Instead of being just a budget, it's a pathway we have to tread to reach net zero in 2050" @lorddeben

Just like quite a few other modelling exercises, CCC use a spectrum between behaviour change and between technological change. #UKCarbonBudget.

Both = best (just like @AEMO_Media's Step Change scenario in their ISP)


'Balanced' is what they use for their recs. "We're doing 60% of the emissions reductions in the first 15 years, and then 40% in the next".

The slinky kitty curve....good to see. No evidence of delaying action to Dec 29 2049, here. #UKCarbonBudget


"By front loading, we're minimising the UK's contribution to cumulative emissions" - really important point. A slow path to net zero - more climate harm than a fast one. #UKCarbonBudget
I don't have time to make this detailed, but here's a little thread about the world's first major politically-charged blackout that was blamed on renewables, in South Australia, in 2016............

On September 28, 2016, an unprecedented tropical storm progressed rapidly across South Australia. Truly - this thing was unusual. The sky folded in on itself. It tore towns to bits.


Australia's @climatecouncil pointed out that the storm was so unusual at least partly due to the influence of climate change, and that this is due to get worse.

I'm going to use brief snippets from my book to fill this out! The storm's primary impact on the grid was the destruction of several major transmission lines. When I say destruction - I mean they snapped like twigs.


Here's what happened in the following seconds:

- A voltage spike from the line falls
- Wind turbines automatically shut off due to software settings that trigger shutdown during a spike
- The interconnector to Vic tried to compensate, failed and died
- All of SA blacked out

Oh my Goodness!!!

I might have a panic attack due to excitement!!

Read this thread to the end...I just had an epiphany and my mind is blown. Actually, more than blown. More like OBLITERATED! This is the thing! This is the thing that will blow the entire thing out of the water!


Has this man been concealing his true identity?

Is this man a supposed 'dead' Seal Team Six soldier?

Witness protection to be kept safe until the right moment when all will be revealed?!

Who ELSE is alive that may have faked their death/gone into witness protection?


Were "golden tickets" inside the envelopes??


Are these "golden tickets" going to lead to their ultimate undoing?

Review crumbs on the board re: 'gold'.
