My teen, who had dreamt of being an astrophysicist, just told me he wants to go to law school because, β€œScience isn’t going to be a priority in the US in the future…I don’t want a job where I’ll be constantly worried my funding will be taken away.”

Gutting. How many future scientists have we lost?

We're now making the climate problem worse three times faster than at the start of the measurements, around when I was born: between 1959 and 1962, the increase was 2.47 ppm.
These years, we achieve that within one year.

Mooie reconstructie, maar wat een potsierlijke opening: "Eindelijk zou er schot komen in het vastgeroeste stikstofdossier, toen BBB in 2024 de landbouwminister mocht leveren."
Er was het jaar daarvoor eindelijk schot in gekomen, en het was volstrekt duidelijk dat BBB dit van de rails wilde helpen.

Czech President Pavel warns: β€œIf Putin wins in Ukraine, we all lose.” He compared secret U.S.-Russia talks on territorial concessions to the 1938 Munich Agreement, calling them dangerously familiar. Letting Russia emerge victorious from this war, he stressed, would be a defeat for all of Europe.

Donald Trump just removed Martin Luther King Jr. Day and Juneteenth from the list of free entry days at national parks.

They are being replaced with Trump’s birthday.

After Elon Musk lashed out at the EU, calling for its dissolution and accusing the Commission of strangling Europe with bureaucracy, Polish Foreign Minister RadosΕ‚aw Sikorski fired back: β€œGo to Mars. There’s no censorship on Nazi salutes there.”

Elon Musk has tweeted nonstop about white babies, white genocide, population decline, and fertility rates for the past week.

This is what it's all about, folks. The supervillain plot is tweeted in real time.

White supremacy. Fear. Anxiety. Hatred. A loathing of diversity.

Today, we fined X for non-compliance with transparency obligations under the DSA.

We're holding X accountable for:
πŸ”ΉDeceptive design of its β€˜blue checkmark’
πŸ”ΉLack of transparency of its advertising repository
πŸ”ΉFailure to provide access to public data for researchers

"This is the last chance for Western countries to convince the rest of the world that they are capable of dialogue rather than monologue, consistency rather than double standards, and cooperation rather than domination."

The temperature in central the Netherlands over the past 320 years. Clearly shows that we're already well over 2 degrees of warming here. This year is heading for 11.5Β°C again.
This coming Monday and Tuesday, we'll even have that average, in December...

"Third, if a permanent or rotating member of the Security Council violates the UN Charter, its membership in the UN should be suspended. This would mean that the body would have suspended Russia after its full-scale invasion of Ukraine. Such a decision could be taken in the General Assembly."

"Second, no single state should have veto power in the Security Council. The veto was necessary in the aftermath of World War II, but in today’s world it has incapacitated the Security Council. The UN agencies in Geneva work well precisely because no single member can prevent them from doing so."

"First, all major continents need to be represented in the UN Security Council, at all times. It is simply unacceptable that there is no permanent representation from Africa and Latin America in the Security Council and that China alone represents Asia."
