#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:

This #NewYear we must get serious about climate change. A big obstacle: our brains.

Current risks are vastly different from our ancestors, but our brains are wired the same. Knowing the science behind decision-making helps us better talk about climate threats & spark action. 1/

I’ve dedicated my career to understanding what factors influence our perceptions of risk & shape behavioral outcomes, especially around climate action.

We clearly do not judge risks accurately. Let’s try this example. What is more likely to kill you:

Ppl often say shark attacks even though plane parts are 30x more likely to kill us. Attacks are more sensational/easier to recall.

Brains react in certain ways to risks around us, rapidly scanning environmental cues (e.g. snake’s stance) with subliminal and automated processing.

How does brain wiring relate to climate action? We're influenced by triggers such as if we can see risk or if we trust who communicates it to us.

Bluntly, we overestimate unserious risks like vaccinating children and underestimate seemingly far away risks like rising sea levels.

Sociology shows how even political identities influence risk perception. A human evolutionary trait allows us to avoid cognitive dissonance from info 1) that isn’t pleasant or 2) contradicts beliefs integral to our identity/tribe. We’re wired to make snap judgements for comfort.

Oh fuck. I am listening to Gormley's interview w/ Patrick Moore about climate change from Jan 21. Gorm is being fed a pile of horseshit and just happily swallowing every word. This is garbage. /1

Moore says you can't go out in the field & see what CO2 is doing. Which is just false. You can go in the field & measure atmospheric CO2 & its change directly. And he calls himself a sciencey guy? /2

Then he's saying, b/c some on the left believe GMOs are bad w/ no evidence, therefore everything they believe they believe w/ no evidence so therefore scientists who say the climate is changing are making up stories? This is ridiculous. /3

Often when I tune into climate deniers, there's stuff I hadn't heard before that I have to do a bunch of reading to find out what's real & what isn't. So far with Moore, I don't even have to make a list of stuff to check to know this is all nonsense. /4

I'm saying, he's going over old, long debunked talking points. This is tired & boring. /5

Many wonder how epidemiology could have become so politicized. But epidemiology - like climate science (the other "mysteriously politicized" subject) has intrinsic politics: to take epidemiology seriously, you have to acknowledge that our species has a shared destiny.

1/

Much of the debate over "liberty" can be summed up as "you do you" - I'll swing my arm over here, you keep your nose over there, and so long as we both respect each others' "freedom," I won't punch you in the nose and your nose will remain unpunched.

2/

This breaks down when applied to epidemiology: "You wear your mask, I'll leave mine at home, and we'll both exercise our freedoms" is like "You swim in the no-pissing end of the pool, I'll swim down here in the pissing end, and we'll both get our way."

3/

We're in the same epidemiological pool, and the science is clear: masking's benefit is primarily in protecting others from you - your presymptomatic, asymptomatic (or symptomatic) spread of particles. Your decision not to wear a mask puts me in danger.

4/

If your worldview ascribes political outcomes to individual choices (implying that poverty or misfortune are the result of a combination of laziness and inferiority), then anything that demands a systemic view challenges its very foundations.

5/

There's a huge gap between what climate scientists are willing to say privately and what we're willing to say publicly, in terms of how dire a situation we're in. Colleagues, integrity demands we close this gap.
