How AI Tools Are Changing Research, Communication, and Education (opens the original)
Read excerpt
Over the past year or so, I’ve invested a lot of effort into learning how to apply AI tools in my research. I’ve become somewhat skilled in using the tools.1 For instance, so far this year, I created four data dashboards: The sites have drawn enormous traffic and spurred a lot of interest. This week I’ll be releasing another major new website, titled the THB Build Your Own Emissions Scenario. It will allow users to create bespoke climate scenarios for direct comparison with the new CMIP7 scenari
Most Countries Have Already Passed Peak Carbon Dioxide per Person (opens the original)
Read excerpt
Here is something that few people are aware of—per capita carbon dioxide emissions (pcCO2) from fossil fuels peaked globally in 2013 and have remained below that level ever since. The trend in pcCO2 is best characterized as a plateau, as shown in the figure below. In fact, in 2025 global pcCO2 was only 2.3% above 1979, even as world population increased by ~88% and total energy consumption doubled. Today I am starting a new series on what we can learn about decarbonization and how it might progr
The Data Center Backlash Is Really About Abundance (opens the original)
Read excerpt
Keeping up with data center–driven electricity demand requires supply-side solutions, not bans. Conventional wisdom holds that the Luddites, the 19th-century English workers who smashed textile machinery to protest automation, were anti-technology. But historians of the movement have added considerable nuance: The Luddites were skilled craftsmen who opposed not the technology but what the technology did to their wages, working conditions, and livelihoods. This perspective lives on—opposition to
Three Hard Truths About France's Wildfires (opens the original)
Read excerpt
The pattern is very familiar: With every extreme event comes claims — from journalists, scientists, and politicians — that we can reduce the impacts of those events by quickly cutting our emissions of carbon dioxide from the burning of fossil fuels. Here are a few examples just in the last week with respect to the wildfires across southern France: The logic is attractive: emissions cause warming, warming causes fires, so cutting emissions stops the fires. Today’s post, as in a recent THB analysi
Why Cutting Emissions Can't Fix Europe's Heat Waves (opens the original)
Read excerpt
Consider how prominent voices in the climate discussion describe the link between fossil fuels and extreme heat: Such claims are ubiquitous: fossil-fuel emissions are framed as a control knob for extreme weather, and turning the knob down will reduce the incidence of weather extremes. In fact, much of climate advocacy is grounded in claims that climate change causes undesirable weather and the solution therefore must be to quickly transition off of fossil fuels. Today’s post takes such claims se
