@nikibrazzola.bsky.social works at the interface between science and policy. Her work has focused on aviation decarbonization, carbon dioxide removal, and carbon certificates.

Beautifully done by Private Eye...

The United States Military Academy has just eliminated all Cadet clubs and activities for POC. Most of these have existed for decades like the Society of Black Engineers. They were there when I was a Cadet in 1987. All of the religious ones remain. This isn’t DEI. It’s white Christian Nationalism.

A study in Nature Communications examines Direct Air Capture’s role in climate-neutral aviation via synthetic fuels or carbon removal. It finds Direct Air Capture-based fuels can cost-effectively mitigate CO₂ and non-CO₂ effects if cheap renewable energy is used. https://go.nature.com/4ajmYuV 🧪

The world has passed "peak child". This was a term coined by the late Hans Rosling, and the most recent data suggests that the world has reached it: the number of children has stopped growing. My data insight on @ourworldindata.org today: ourworldindata.org/data-insight...

It was the best of times, it was the dumbest of times.

On a related note, the passing of same sex marriage laws in the United States (and the resultant disappearance of the culture war around it and accusations of "gay agenda" coincided with a drastic reduction in gay teen suicide arstechnica.com/science/2017...

For the ‚nerdy but worthy‘ series, a great thread on why we likely underestimated biochar permanence so far. 🌱🪨 And a big welcome to BlueSky to @sebastianmanhart.bsky.social, who in the last years shaped the CDR discussion on LinkedIn 🙏

i’m kind of amazed at how this is just the crudest, most obvious n****rbaiting you can imagine. “the people you don’t like, yeah, they are responsible for everything bad.” and it works!

I am a climate scientist and this is correct ⬇️

Freedom of speech in tech guru language (i.e. Zuckerberg) = freedom to make millions out of viral hate speech, freedom to infiltrate and manipulate politics to bend laws in their favour, freedom to let addictive and polarising content spread uncontrolled.

If PFAS is bad for human health, we’re forever screwed.

This means that leading up to the Paris Agreement we thought we had a lot more time to achieve the 1.5-2C target

You can see why I look to Christiana for inspiration in our fight for a better world. She’s the architect of the Paris Agreement, but has never rested on her laurels. She just keeps going. 💚

'Blue hydrogen' is hydrogen made from natural gas, the friendly-sounding name for methane—a highly potent greenhouse gas. The fossil fuel industry hopes to inject it into the gas grid for heating homes. But it’s as bad as coal for the climate, as @kevinclimate.bsky.social and I explained here.

1) This is my top highlight. We found that the global North net-appropriates more than 800 billion hours of labour from the South per year. This occurs because Southern wages are 83–98% lower than Northern wages for work of equal skill in the same sector. www.nature.com/articles/s41...

Myths about heat pumps block uptake 🚫 False: “Heat pumps don’t work at low temperatures” 🚫 False: “Heat pumps don’t work in old homes, flats, or less insulated homes” 🚫 False: “Heat pumps are noisy” Myth busting is behavioral & I loved having a small role in this work ⬇️ 🔗 shorturl.at/snGkB

Only 5% of academics come from the 20% poorest households. They are both more likely to not publish and to have outstanding publication records, as they seem to be more likely to venture off the beaten path. Climbing the Ivory Tower: How Socio-Economic Background Shapes Academia lnkd.in/eeJsryQw

Climate change got worse, in 2024 too. This is clear from the annual report by World Weather Attribution: lnkd.in/gETnaBs2 1. Extreme weather grew worse 2. Human deaths grew over 3,000 3. Worse heats, storms, floods and droughts were recorded 4. The Amazon was impacted especially badly

Fossil fuels make us poor & cold. UK Gov paid £21 billion of our money for the price cap when prices last spiked. Even then, people couldn't heat their homes. Ambitious action to switch to home-grown renewables will make us all better off (except the oil billionaires). 🧵1/3

❓Where do the profits of Oil & Gas flow ❓ Spoiler: not to you. Great visualization by Joseph Gelfer to keep in mind when discussing a just transition in the oil and gas industry.

Cool new paper well articulating a well-known problem to scientists but not to the public: planting trees 🌳🌲 is not a solution at higher latitudes (and not just because of albedo!) www.nature.com/articles/s41...

Responding to systemic violence with isolated violence is an act of entitlement, a narcissistic presumption that we alone have seen the truth and have the ‘radical honesty’ to do something about it, as Mangione’s manifesto puts it. System change requires a lot more humbleness and self-reflection.

People in aviation mitigation ✈️keep on fighting on whether demand reduction OR technology is the solution. Here a recent example (in German, unfortunately): www.tagesanzeiger.ch/fliegen-luft... Obviously BOTH are the solution. But lower demand will pressure airlines to adopt new technologies.

This looks like a great paper--also consistent with related recent research that finds people who experience climate shocks are more likely to support climate action (no matter their political ideology). So, personal 👏experience 👏matters (and affects attitudes)

Stop buying bottled water and they’ll stop selling it.

I am disappointed but not hugely surprised that the biggest piece of positive news since I can't remember, the fall of Assad and the freeing of Syria, is not being widely celebrated by leftists. A few words on why, and why this is sooooooooooo messed up. 🧵 1/ bsky.app/profile/amer...

Half a pound of this yellow powder removes as much CO2 as a tree Berkeley scientists have developed a powder called COF-999 that can pull carbon dioxide out of the atmosphere at room temperature. It holds the gas until the powder is heated, when the CO2 can be safely captured. Then the powder can…

I now consider my trip to Zürich a success since I got @nikibrazzola.bsky.social to join Bluesky! Every time we meet, I learn something interesting. Follow her if you are interested in climate policy and its relationship with technology.

Contrail avoidance may be one of the greatest opportunities to shave off short-term climate warming due to aviation at low costs: www.transportenvironment.org/articles/con... It’s however very important that it does not come at costs of higher CO2 emissions, as these have longer lasting impacts.

One of Switzerland’s parliamentary chambers passed last week a proposal on CO2 infrastructure: www.parlament.ch/de/ratsbetri... If this gets through the second parliamentary chamber as well, then the Swiss government will create one of the first laws in the world to kickstart CO2 pipelines etc.
