Thread about my and my co-authors’ newly published paper in Political Behavior, wherein we report 4 sets of tests that demonstrate no partisan or ideological asymmetry in conspiracy theory beliefs or conspiratorial thinking —>
Quote Tweet
I just published a new paper with my excellent colleagues @PoliPsyProf Christina Farhart, Adam Enders, Kyle Saunders, and @HDrochon. Are conservatives and Republicans more likely to believe conspiracy theories?

Thirty years ago, US Democrats & Republicans were on the same page when it came to climate change. Within 15 years, it had become - and remains - the most politically polarized issue in the country. How? The result of deliberate and strategic investment in doubt to delay action.

In 1993 a band of wealthy industrialists allied with a PR firm to battle against scientists. At stake was their wealth. Every climate denier on Twitter is their legacy. As is the rising temperature and the growing list of extinct species #climatechange #netzero #nomoretime

Susan Joy Hassol () & I place this observation in the context in a larger discussion of climate change impacts on extreme weather and how current models may not be fully capturing those impacts, in this commentary today in : thehill.com/opinion/energy

We have had resonance conditions for a planetary wave with wave number 7 during the past week, with large wave amplitudes. Think meanders in the jetstream. This Leads to simultaneous heat waves in different areas of the Northern hemisphere. Graph shows tropospheric winds.

Thirty years ago, a bold plan was cooked up to spread doubt about climate change. The little-known meeting - between America's biggest industrial players & a PR genius - forged a devastatingly successful strategy that endured for years, with lack of action

That's why I fight so hard against personally guilt-based attempts to inspire climate action, because that's what's actually at the root of most denial. For more, read:

The other day, I decided to conduct an experiment. I set a timer for 3 hours and counted how many times I was publicly shamed here on twitter during that time. The answer? 12. And since then I've counted dozens of examples of others being shamed, as well. (thread)

The excellent book and documentary, Merchants of Doubt, tells the story of how doubt and denial fought knowledge of the health impacts of tobacco, muddied the waters on fire retardants, and delayed climate action. Highly recommended!

Mr. Biden took useful but small-bore climate actions today, including opening up new areas in the Gulf of Mexico for wind leases. The bigger test: will he declare a full-on climate emergency, and do things like *stop* oil and gas leases in the Gulf? The next weeks will be crucial

Tackling climate change is hard; but doing nothing will be catastrophic.

Nearly 676,000 jobs for 10 years. About $6.2 billion in tax revenues. These are among the economic benefits from #cleanenergy and climate provisions before Congress. But only if lawmakers act. Congress must find a way. nature.org/en-us/newsroom

Australia on a lose-lose path. Ground zero for massive heat & fire due to global warming. Hitting nature that has lost resilience - to cope with shocks like climate extremes - due to biodiversity loss. A story of crisis and decline. High time to turn page

As , says, this unprecedented event WAS linked to climate change. We wouldn't have seen temperatures of 40C/104F in LONDON absent human-caused warming of the planet. This is climate change folks. It will get much worse w/out rapid reductions in carbon emissions.

24 all-time records in UK today, inc. the all-time UK record shattering 104.4 in London. This event is virtually impossible without a heated climate, supported by recent research at the @metoffice. London btw is further north than Calgary & any US city. GFX: CoolWx 24 hr loop
