This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

Climate engineering would alter the oceans, reshaping marine life – our new study examines each method’s risks
Some methods being tried to counter climate change shift the ocean’s biology or chemistry. Others would deflect solar radiation. All have consequences for marine life.

The heat energy we added to the ocean LAST YEAR is the equivalent of:
- Detonating ten hydrogen bombs every minute
- operating over a hundred large power plants continuously for all of written human history
- Five times all the electricity human beings have ever used
- Detonating ten hydrogen bombs every minute
- operating over a hundred large power plants continuously for all of written human history

Ocean heat content increased by 23 billion trillion joules, which was around 39 times greater than global primary energy use this year. This is the largest rise in OHC since 2017; overall OHC has increased by over 500 zettajoules since the 1940s.

China is now the leading clean energy powerhouse with the West falling behind.
The transition is inevitable; the key question is where and how fast it happens.
I look forward to discussing this in Davos next week at the World Economic Forum, facilitating a live-streamed session on electrostates.

A landmark report into how deep sea mining could affect biodiversity on the sea floor has found that almost 40% of creatures in the immediate seabed area were lost in the tracks of mining machines.
