1/ In reflecting on my work this year I have just realized that everything I published concerned climate change: here is a roundup of my 2020 writing on #climate #justice, climate #reparations, climate #debt, climate #displacement, climate #mobilities & #disaster #recovery

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.

Thread on very strong inbound CA storm. A cold & clear morning will quickly give way to increasing clouds, NorCal valley rain & snow down to 1,500-2,000 ft (locally lower) later this PM. Current satellite imagery shows this strengthening system off the coast. (1/10) #CAwx

Tonight, a rapidly intensifying cold front will sweep across NorCal. This front will be unusually well defined, for a CA winter storm, and will replace an already cold airmass with...another cold airmass! (2/10) #CAwx

The cold frontal passage is expected to be quite dramatic across NorCal in the overnight hours. A convective "narrow cold frontal rainband" (NCFR) will likely develop, which could bring a period of torrential rain or snow to many areas, as well as possible lightning. (3/10) #CAwx

Extremely heavy precipitation is possible for a 30-60+ minute period when this NCFR feature moves ashore. Over an inch of rain could fall per hour in some spots. This portion of the event poses a high threat of debris flows in/near recently burned areas. (4/10) #CAwx

In addition to torrential rainfall, the cold front/NCFR will be accompanied by very strong wind gusts across much of NorCal. In fact, high-res models are suggesting potential for gusts of 60-70 mph even in lower elevation places. Widespread power outages possible. (5/10) #CAwx
