Climate scientist at CICERO, Oslo. I try to talk about climate science, but inevitably start talking about trains and bicycles if left unattended.

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

The Methane spike in the early 2020’s has been explained in two new studies. A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land are to blame.

Why methane surged in the atmosphere during the early 2020s
The atmospheric methane (CH4) growth rate surged after 2019, peaking at 16.2 parts per billion per year (ppb year−1) in 2020 before declining to 8.6 ppb year−1 in 2023. Using multiple atmospheric inve...

The Trump #climate report attempting to overturn the ruling that greenhouse gases are pollutants was grossly scientifically inaccurate. Turns out it was also illegal.

A past criticism of Variable Renewables Energy (VRE) from wind & solar was that their power was intermittent & thus unreliable. But the drop in battery storage cost has ushered in the age of firmed renewable energy (FRE). Renewables with storage are displacing import and fossil fuels. 🧪🔌💡☀️💨💧🔋

NSF has just put out a call for 'concepts' on how to evolve weather forecasting & computing related parts of NCAR.

The word climate *does not appear* in this document, but it does ask for ideas on "Ownership of the NSF NCAR Mesa Lab building for private use"

Call for input by March 13....

People - don't get ChatGPT to write your job application letters. When you read 100+ of these things in a row - they all sound identical, with generic references to the job ad. You can pretty much guess the prompt they used.

The easiest way to stand out is to be your imperfect, brilliant self.

These dynamics are clearly happening - seemingly creating larger oscillations / stupider decisions over time. But even if the stock market resets, there is also cumulative damage to America's international standing which is not reversed when trump steps back from the brink.
The TACO cycle:

Markets want to price in TACO. But TACO only works if Trump sees stocks tank.

So we get a loop: Trump does things → nothing happens (markets already priced in TACO) → that emboldens him to do more → until markets start to think he might not TACO → stocks fall → TACO is restored.

These things can be simultaneously true:

1- We can't meaningfully address climate change if the world is held hostage by authoritarians who are actively seeking to undermine international agreements.

2- decarbonisation is a critical part of gaining leverage against those authoritarians

It feels like the necessary response of the civilised world to rising authoritarianism might be defined by this speech, if others follow.

Principled, but strategic. Intelligent, but forceful. Multilateral, but not complacent in the role of existing institutions.
Seriously, WHEREVER you are in the world, I recommend watching all of Canadian Prime Minister Mark Carney’s powerful & already famous speech at Davos.

Can’t underestimate its leadership importance.

Key line: “Middle powers must work together, because if we’re not at the table, we’re on the menu.”

If the last decade has taught Europe anything, it should be that reliance on fossil fuel imports is a strategic liability which will be exploited.

Climate aside, decarbonisation is security.

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.

You have to block them immediately. The full nuclear. They are only here to make folks angry, and that can’t happen if we lock them out.

If there's a silver lining to this madness, perhaps it can at least bring wider Europe together with a sense of common identity
Sweden’s Prime Minister, in a new statement on Greenland:

“We will not let ourselves be blackmailed… Sweden is now having intensive discussions with other EU countries, Norway, and the United Kingdom for a coordinated response.”

Worth noting that the EU’s reluctant tariff concessions to the US, agreed between VdL and Trump at Turnberry, haven’t yet been approved by the European Parliament.

There’s no realistic prospect of the US deal going through now.

Called my Congressppl’s office to ask them to oppose any DHS funding that does not rein in ICE. I also asked them to oppose any State or Defense funding that doesn’t include the NATO Unity Preservation Act, which would block the use of funds for military or economic aggression against a NATO ally.

A rare bit of good news from the US. House republicans seem to be pushing back against Trump's huge proposed cuts to science.

NSF, NASA, NOAA - all look set to be near flat, or - for DOE - even a slight increase.
