I posted this thread to LinkedIn because I’m a glutton for punishment and the CDR shills are big mad.
🧵CO₂ removal (CDR) is back in the news, but just because the UNEP report says we need CDR, it doesn't mean we'll have CDR. Many challenges will take decades of research and negotiation to solve. Here are some examples:

Technological: We currently don't have any durable CDR method that scales.

This settles @mark-carney.bsky.social’s gov position on sustainable development.
I get we are living through massive geopolitical changes, but dismissing Nature and the ecosystem services it provides to sustain society -and the economy- seems just foolish 😔

Listening to a man at the farmers market explain he’s out of eggs as “the ladies aren’t producing due to heat stress”— and another poultry vendor says he’s out, as he can’t keep them in this heat.

Climate change is all around. We just have to open our eyes to see how it’s affecting our daily lives.

A rational evaluation of the risks would immediately trigger a slow down & setup of strong regulatory frameworks for AI development. Like climate change, the lack of decisive action indicates that greed & a FOMO race for power drive decisions. Maybe is just stupidity.

In the middle of all the turmoil, I want to thank Ainsley Hawthorn for her historical pieces, and to a mainstream news outlet like CBC for giving them space. I always learn something from them, and are a refreshing reminder that there is more out there that doomscrolling.

The most important climate action you can take isn’t obsessing over your individual carbon footprint.

We need to change the system so the easiest, most affordable choice for everyone is also the best choice.

How do we change a system?

It starts with your voice!

A good reminder that it can take far longer than we think to restore full ecological functionality & diversity to an ecosystem.
Something to keep in mind nowadays where longer term consequences are typically ignored by decision-makers pursuing short term economic gains.

1/ Is this headline misleading?

Yes, but not in the direction you'd expect.

The problem isn't that it exaggerates. It's that it puts in 2100 what has already started. 🧵

Objectively, this is good new.

Still, CAD 34 millions pales in comparison with the billions in federal funding that will be used to prop up the building of another pipeline which, also objectively, will make climate change worse.

The dissonance here is deafening.

European summers aren't what they used to be!

Grey curve is the climate of 1950-90. Every coloured line is a summer since 1991. Every one since 2005 sits beyond the 95th percentile of the curve.

This isn't a shifting #climate. It's already a new one! 🤯🥵

As wildfires force thousands out of their homes, and Canada bets on more fossil fuels to deal with the trade war, not only are people’s health, Nature conservation, & sustainability being dismissed… it seems the rule of law is also a drag to be skipped over… sad times
