20 dated positions, 2026, in their own words. Our reading of what Andrew Dessler has said — not written or endorsed by them.

  1. Our readingAttacks on extreme event attribution are primarily attacks on the scientists rather than the science itself.

    Their wordsAlmost every attack on attribution science is an attack on the scientists. Almost none of them engage the science.

  3. Our readingFossil fuel interests are attacking extreme event attribution to protect their business models.

    Their wordsFossil fuel interests and their proxies are attacking extreme event attribution because it’s a threat to their business model.

  5. Our readingThe strategy used against attribution science is to libel scientists and exaggerate uncertainties to justify inaction.

    Their wordsThe strategy is simple: libel the scientists, exaggerate uncertainties, and convince the public that the science is too unsettled to justify action.

    Their wordsUnderstanding climate change will help Texas graduates manage those risks and identify new business opportunities for solving the problems that climate change creates.

  9. Our readingRising atmospheric water vapor raises the ceiling on how extreme rainfall events can become

    Their wordsSo the increase in PWAT is not just a weirdo statistic. It is a statement about the ceiling on the worst rain events we can face.

  11. Our readingClimate change made the July 2025 Texas flooding more intense than it otherwise would have been

    Their wordsGiven that we can connect increases in PWAT to global warming, we can confidently conclude that climate change made this rain event more intense than it otherwise would have been.

  13. Our readingTemperatures from high-emissions climate scenarios are a plausible upper bound on future warming, even though the emissions themselves are unlikely.

    Their wordsthe temperatures produced under RCP8.5/SSP5-8.5 are a reasonable upper bound on what the future climate might be.

    ↗The Worst Case Is Still on the Tabletheclimatebrink.com 1st of 3 in this piece

  15. Our readingClimate models may be underestimating how much future warming will occur.

    Their wordsKeeping the RCP8.5/SSP5-8.5 runs as a plausible upper limit is particularly important given that recent research has emphasized the possibility that models are underestimating future warming.

  17. Our readingThe same global average temperature can arise from greenhouse warming or from El Niño and still produce very different regional climate impacts.

    Their wordsThe catch is that the future world that has been warmed by greenhouse gases and a present-day world that has been temporarily warmed by El Niño can have the same global-average temperature while having significant differences in the impacts of this warming.

  19. Our readingClimate change is making wildfires significantly more severe.

    Their wordsClimate change is absolutely making these wildfires more severe - there should be zero doubt about that.

  21. Our readingThe economic damage from climate-driven wildfire smoke deaths exceeds all other previously estimated categories of U.S. climate damage combined.

    America

    Their wordsYou read that right: The cost of climate-worsened wildfire smoke alone is larger than what earlier studies said every other estimated cost of climate change would be, combined.

  23. Our readingNewly discovered, costly climate impacts like wildfire smoke should strengthen the case for cutting greenhouse gas emissions.

    Their wordsThis should turbocharge our resolve to reduce emissions of greenhouse gases.

  25. Our readingThe post-1970s global increase in heatwave frequency is caused by greenhouse gas emissions from human activity.

    Their wordsThis differs from the Dust Bowl because it is a global signal, occurring essentially everywhere. This is almost certainly due to greenhouse gas emissions from human activities.

  27. Our readingCooling or warming global temperature by around 10°F would produce an unrecognizably different planet.

    Their wordsIf you cool the Earth by 10 degrees Fahrenheit, you end up with a completely different planet.

  29. Our readingClimate change's effects will unfold as sudden catastrophic events rather than as steadily accumulating small changes.

    Their wordsThe transformation to come will be decidedly nonlinear, meaning it will not occur as small impacts over many years but rather a series of infrequent, huge events of enormous destructive power.

  31. Our readingIt is already too late to fully prevent climate change because the atmosphere has been irreversibly altered by carbon pollution.

    Their wordsAt this point, we've missed the boat at completely preventing climate change. Our atmosphere has been fundamentally altered by carbon pollution.

  33. Our readingClimate skeptics' opposition to data adjustments is driven by which results those adjustments produce, not by scientific principle.

    Their wordsthe opposition to adjustments is entirely instrumental: climate skeptics like the results that the raw, biased data give them for the US, and they don't like the results that bias-corrected data give them.

  35. Our readingThe intense U.S. heat of the 1930s was driven by regional natural variability plus human-caused poor land management (the Dust Bowl), not global warming.

    America

    Their wordsthe heat of the 1930s was a regional event, due to a combination of unforced variability and human activities (poor agricultural land management).

  37. Our readingClimate models are underestimating how intense heatwaves become at a given level of global warming.

    Their wordsthe temperatures seen in France show that climate models continue to underpredict the magnitude of heatwaves for a particular level of global warming.

    energy

    Their wordsWithout a move away from fossil fuels, future heatwaves will keep testing the limits of public health systems and more people will die.
