Hegseth Says Climate Change Is ‘Crap.’ The Military Is Still Bracing for It Climate is now a verboten topic in the Pentagon, but the battle against storms, fires, floods and rising seas hasn’t stopped.

The Pentagon won't say "climate."
Fortunately, they're still preparing for what's coming.

World Bank Climate Change Knowledge Portal chart
Observed Change in Distribution of Average Maximum Surface Air Temperature. Japan • 1951-2020
What you can see in this figure
We compare successive 30-year climatology periods by visualizing their 30-year mean and spread (standard deviation) using a bell-shaped distribution.
Understanding the Data: Implications and
Utility
This approach allows us to discern, for example, if years are becoming consistently hotter/drier/wetter or if more intense temperatures are occurring with greater frequency or if variability is becoming larger or smaller, even in cases where the average temperature (the mean) shows little change.
Extreme events have the most impact over human populations. This plot gives as a first idea on the historical change in extremes.
Chart shows three distributions: 
Yellow, 1951-1980, average max temp ~14.6°C
Orange, 1971-2000, amt ~14.9°C
Red, 1991-2020, amt ~15.6°C

Chart of global fossil-fuel consumption, electricity consumption and GDP, all indexed to 100 as of 1973. Before 1973, GDP and fossil fuels rose in tandem. After 1973, GDP and electricity were in tandem, tripling by 2020, while fossil fuels decoupled and haven't even doubled. Source: Ember

Remarkable chart from this great @ember-energy.org piece. The '70s oil shocks permanently broke the fossil-fuels/GDP relationship. The 2020s shocks will trigger an even more dramatic paradigm shift against polluting fuel and toward clean energy

Economists say the oil market is "tight". Supply and demand are typically fairly balanced, which means small shifts in supply can have disproportionate impact on prices.

The largest supply disruption in history happened in March and oil price stayed below $120. Time to revise the "tight" part?

Opinion | NASA Flew by the Moon, but Behind the Scenes, Its Science Is a Chaotic Mess

Experts don't seem like they've hit on the obvious solution here, which is to dress oil tankers up like Hollywood producers and get them through the Strait of Hormuz by saying they're scouting a new sci-fi movie.

Projections that the world could be destroyed in the next century should always be tempered by the thought that since 1945 we've known the world could be destroyed in the next 90 minutes.

art002e009276 (April 6, 2026) - In this view of the Moon, the near side (the hemisphere we see from Earth), is visible at the top half of the Moon disk. It is identifiable by the dark splotches. These are ancient lava flows from a time early in the Moon’s history when it was volcanically active. The large crater that appears below the lava flows, dark in the center, is Orientale basin, a nearly 600-mile-wide crater that straddles the Moon’s near and far sides as is partly visible from Earth on the edge of the Moon. In this image, we have a full view of the crater. Everything below the crater is the far side, the hemisphere we don’t get to see from Earth because the Moon rotates on its axis at the same rate that it orbits round us. Credit: NASA

At this stage of the game, it is crystal clear that the internet, as a whole, was a huge mistake. But every now and then, we find incredible uses for it, like this photo gallery of Artemis II pictures.
