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

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. go.nature.com/4ajmYuV 🧪
This is figure 1, which gives an overview of emissions and removals in gigatonne CO₂-equivalent emissions based on the modified global warming potential (GWP*) metric.

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...

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. 💚
A LinkedIn post by Christiana Figueres saying, “Maybe the simple lesson of the climate crisis is this: to step outside of ourselves and really strengthen our muscles of humanity, of compassion. It's about time we evolve beyond our reptilian brain, operating in a mode of collaboration - the only path to collective success - instead of extreme competition which is now a proven path to destruction. 

Will we learn the lesson? No guarantees. 
But let's give it our best shot.”

'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.

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

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.

Können wir bald mit reinem Klimagewissen fliegen – oder braucht es Verbote?
Ab Januar müssen dem Kerosin der Flugzeuge zunächst 2 Prozent nachhaltige Flugkraftstoffe beigemischt werden. Bis 2050 sollen es 70 Prozent werden. Genügt das, um die Luftfahrt klimaneutral zu machen?...

Opposition to bottled water has primarily focused on blocking plants and increasing access to tap water. The closure of Ontario’s largest bottled water plant shows that these efforts can succeed.

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 be used again. We desperately need inexpensive ways to remove excess carbon dioxide from the atmosphere. The Mauna Loa observation station shows CO2 at 422 ppm in September…

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.
