Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

“Because green skyscrapers and high-rises are a bullshit non-solution to serious systemic problems.”

“But if you want greenery on a building nonetheless, do I have an idea for you – a portable, modular, scalable solution called ‘potted plants on your balcony’.”

I insists these are great, and not a solution to anything (the green thing is just marketing). Basically a form of fasade, the look of things etc.

And regarding implementation, they are just dog shit bad bcs often neither contractors nor architects are incentivized to spend time & money on it (they get most of their moneys by selling, not maintaining).

But there are solutions that were properly implemented and work all over the world. Even as retrofits to old buildings. Or to cover up outside walls where there aren't any windows for various reasons.

And also, most (green or non-green) highrises have some leaks, it's basically just a big complicated block that is bound to have imperfections.

And also 2, big core systems implemented have to be maintained as designed. Just like sprinkler systems have to be inspected and tested by law. Eg if we stop maintaining our air ventilation system (with filtration, humidification, and some pre-heating/cooling) I bet we get bacteria and fungi (maybe invertebrates) pumped around the building.

Exactly.

And hospitals had to solve the problem which is a system many buildings nowadays use (a bit depending on local climate needs). We now have osmosis water filtration for the humidifier (like 10+ kW for colder winter months?), HEPA filters before and after, mechanical & screen filters for the inlets (for potential smog particles, pollen, paragliders, that soft or thing) and probably much more stuff (various sensors, noise traps, regulators, fans, ...). All components have their own maintenance needs.

But if we were to cheap out and not hire actual professionals that are good at their jobs ... believe it or not, we all turn into an army of legionnaires and storm the city. And since we are in Europe, I mean highly organized Roman legionnaires.
