I really need to take a deeper dive on these IPBES assessments. It is like IPCC for climate change, but science of biodiversity, governance, and change.

IPBES @ipbes.net · 15h

📊 The IPBES #NexusAssessment Report highlights how nexus governance can address indirect & direct drivers of change as an alternative to siloed approaches.

Learn about the key components of a nexus approach with this graphic.

💡 https://www.ipbes.net/nexus-assessment

An infographic explaining scaling approaches in nexus governance. At the top, four speech bubbles illustrate different scaling types: "Scaling deep" (showing thought processes), "Scaling up" (institutional growth), "Scaling down" (distribution), and "Scaling out" (geographic expansion).

The main diagram flows from left to right showing:

Left section: Lists indirect drivers (Economic, Demographic, etc.) and direct drivers (Land/sea use change, Climate change, etc.)
Middle section: Shows nexus challenges and elements with icons for biodiversity, water, agriculture, and health
Right section: Depicts "Key components" of nexus governance including:
Decision-support tools
Capacities (showing analytical, motivational, bridging, and social networking)
Enhanced opportunities for diverse actor engagement
Implementation of response options (lightbulb icon)
The bottom shows five key components of NEXUS GOVERNANCE:

Integrative and holistic framings
Inclusive approaches
Considerations of equity and accountability
Processes for collaboration and coordination
Adaptive, reflexive and experimental
The design uses a color-coded system to show relationships between different elements and processes.

Really cool podcast, about a futuristic carbon-free energy source. But would the waste heat from this process contribute to significant global warming if this energy source was tapped at large scale?

David Roberts @volts.wtf · 5d

Today on Volts: geothermal startup Quaise is using microwaves to pulverize rock, drill down miles, & access levels of heat that cause water to go supercritical, so it holds exponentially more energy. The promise is geothermal power with 10X the productivity -- enough to lure FF giants into the biz.

Super-deep geothermal drilling ... with microwaves

I talk with Quaise CEO Carlos Araque about a technology that could persuade the oil and gas industry to drill for heat instead of fuel.

An excellent resource on the structural, systemic, and institutional changes necessary for innovation, with a (much needed) focus on the climate adaptation in conservation sector. www.nwf.org/-/media/Docu...

I actually think plenty is invented in this country, but there is no incentive to scale it up because monopolies, especially tech monopolies, are bent on extracting wealth while stopping change. And innovation requires churn.

Chris Hoving @choving.bsky.social · 1d

It is obvious to me. But then I was raised by 1960s/70s political activists, who often talked of "integration" and "feminism."

Chris Hoving @choving.bsky.social · 1d

What is shocking is when the nonlinear gets circular. I was listening to Woody Guthrie recently and came across what seemed to be very spot on satire of MAGA (Mean Talking Blues), only to realize it was anti-fascist.

Not sure it is exactly a thread of hope, but it is solid political science about a less well studied movement that led, in part, to this moment.

Sort of, learn from the past in hopes of re-creating past success.

Federica Genovese @fgenovese.bsky.social · 2d

Going through some history of climate politics notes from last week, I realize we dont appreciate enough the climate mobilization of mid2010s and subsequent electoral green wave of late 2010s.

That moment was never really meant to be in the cards and we need to better study how we got there

Similarly, our lungs are tube and sacks in tube and sacks in tube and sacks, such that flattened out, they would be about 70 m2 or half a tennis court.

These huge fractals shapes are the only way we get enough oxygen and enough fuel fast enough to keep our fires lit.

Chris Hoving @choving.bsky.social · 2d

Evolution solved this via folded fractals for fuels and branching fractals for oxygen. Your intestines are not just a long tube folded in your belly. The walls of the tube are folded, and those folds have tiny folds, such that flattened out it is about 32 m2.

Back to fire. A food fire will die if there is too little fuel or too little oxygen, and getting fuel out of solids and oxygen out of air and both into liquid (our bloodstream) is a challenge because diffusion across a membrane is very very slow. Far to slow to fuel our big brains.

Moth antennae are fractals. Moths fly at night and it is hard to find the opposite sex via chemical pheromones. They need a huge area of chemical receptors, and they get it by teeny feather shaped antennae on tiny feather antennae all over thier antennae. Cell phone antennae mimic moth fractals.

Fractals are self-similarly repeating shapes, and fractals are common in natural systems. (Human engineers prefer Euclidian shapes like simple rectangles and circles.) Think tree branching, sea shell swirling, or puffy clouds.

Chris Hoving @choving.bsky.social · 2d

There is alot of chemistry between the oxygen and fuel in and energy out. I am glossing over years of college level biochemistry. But the fact remains that the basic fun fact our existence is O2 + fuel in and CO2 + H2O + energy out. Just like fire 🔥.

Chris Hoving @choving.bsky.social · 2d

A fire is air, heat, and fuel in a chemical reaction that combines combines the oxygen in the air with hydrogen in the fuel to make H2O and CO2 and lots of extra energy. In a wood fire, that energy is released as heat. In us, energy is heat, muscle movement, and nervous system electricity.

My apologies. I got carried away in my info dumping zeal and forgot the assignment. Please accept this thread of what I consider the most fun animal fact: we are, like all mammals, each a fire that is fueled through fractals.

Animals that eat grass need long digestive systems because it take a long time to digest grass. Rabbits shortcut this process by passing the grass through twice. They literally eat thier own shit.
