This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...

Some proposed climate “solutions” just don’t stack up against an objective, evidence-based perspective.
That’s why the Drawdown Explorer calls these “Not Recommended” climate solutions.

With current pledges, the world's on track for 2.6°C of warming in 2100 compared to preindustrial levels.
10 years ago, before the Paris agreement, it was 3.6°C
20+ years ago, we thought it would be 4-5°C
So 2.6°C is better, but the problem is that climate impacts are way worse than we predicted.

It's astounding how much CO₂ we put into the atmosphere each year by burning fossil fuels.
For comparison, we all agree that plastic pollution is bad, but the mass of ALL THE PLASTIC humanity has ever produced is only 25% of the CO₂ we emitted into the atmosphere in 2025.

Still no peak. Emissions are projected to increase by 1.1% in 2025, reaching 38.1 GtCO2. An all time high.

Nuance is needed. For example:

Not everyone eats the same amounts (see below).
And we have to stop just wasting it! An estimated 40% of the food we create is wasted.

CO₂ removal (CDR) deployments require materials and energy, which emit CO₂. That’s why we talk about net CDR.
Even if CDR affects ecosystems, it’s likely minor compared to the significant negative impacts of climate change on ecosystems. So we should focus on the net ecosystem benefits of CDR.

"Build as much clean energy as possible as fast as possible" should be our No. 1 national priority in the coming decade. All our national resources should be bent to the task. The president should talk about it every week in a national address. It should be the moon shot X100.
In order to keep global warming below 1.5C or 2C, we need to move industrial activity to clean energy. This will MORE THAN DOUBLE our global need for electricity.
We are going to need a LOT more wind, solar, geothermal, and other clean electricity than most people are expecting.
