Rep. Angie Craig: "We were told because this facility is being funding by the 'Big Beautiful Bill,' not the congressional appropriations act, that we would not be allowed to enter the facility. That's complete nonsense ... I informed them they were violating the law. They said they didn't care."

2025 was the hottest year on record for ocean heat content. Unfortunately, we now say this every year. 🥹

"In addition to setting a new record in 2025, the global
ocean continues to show sustained and intensified warming."

Kelp and kelp forests are essential for a healthy ocean, but the answer to this question may surprise you. Kelp forests are found in cold and temperate waters dotting coastlines around the world. They’re immensely important ecosystems that provide the...

"No former president since John Tyler—who later became a Confederate lawmaker—has warmed to the prospect of civil war quite as much as Trump, who in late May “re-truthed” a post on his social media platform positing it as a solution for our “failing” nation." - Joshua Kendall @motherjones.com

The ocean is a carbon sink, absorbing 90% of the excess heat released from greenhouse gas emissions, leading to cascading effects: marine heatwaves, ocean acidification, ice melting, sea-level rise, habitat loss, and biodiversity decline. #WetTribe #TidetotheOcean #CoralBleaching #OceanAcidification

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.

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.
