It's an old and obvious pattern. An unpopular president - failing on the economy and losing his grip on power at home - decides to launch a war for regime change abroad.

The American people don’t want to “run” a foreign country while our leaders fail to improve life in this one.

Venezuela, to the Trump administration, is about oil, not the Venezuelan people or democracy. There’s no plan for what comes next. Trump’s remarks today confirmed it.

Trump: "We're going to have our very large United States oil companies go in, spend billions of dollars, fix the badly broken infrastructure and start making money for the country. And we are ready to stage a second and much larger attack if we need to do so."

Tree roots stabilize soil, preventing erosion & landslides. Without them, heavy rains wash away topsoil, causing floods & disasters. Deforestation leads to soil degradation—up to 48% loss of soil carbon when forests turn to cropland. Short-term gain, long-term catastrophe. 🏞️💔 #StopDeforestation

Centuries-old trees aren't just wood—they're massive carbon sinks, storing CO₂ that would otherwise fuel climate change. A single ancient tree can hold tons of carbon for hundreds of years. Yet we're burning them for short-term profit. This isn't development. 🌳🔥 #Deforestation

Our Solar System is orbiting the center of our Galaxy at about 220 km/s so in 2025 we collectively traveled something like 7 billion kilometers across the Milky Way. Once in a while, when you have a moment, it’s worthwhile to take a look around, see where you are, and appreciate how far you’ve come.

We’re closing out a year filled with unprecedented attacks on science, but the pushback is growing. Hear from UCS President @gretchentg.bsky.social on how UCS and the scientific community are standing up for science:

Or rather, all too believable. If you want to suppress all knowledge of how a relatively small number are enriching themselves by destroying our shared home then this destruction, following on the heels of the funding freeze for the national Climate Adaptation Science Centers, is completely logical.

Trump officials shut off funding for climate adaptation centers

A third of the U.S. Geological Survey’s Climate Adaptation Science Centers are expected to drastically wind down and possibly close after Sept. 30.
