Climate - truthful information about climate, related activism and politics.

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.

Honestly this is why I'm so into the idea of airless tires. Everyone just happily ignores this waste and I don't get it

Probably it's the missing possibility to tweak the stiffness or rigidity according to ones special demands. An air filled tire offers this possibly to adjust the driving behaviour by elevating or decreasing the pressure. These airless tires don't, which is good for a car driven on road, but isn't for bikes where the setup is usually adjusted to the demands of the driver.

I'm not entirely convinced of this being the case. Adjusting tyre pressure is something that is always looked at quite seriously by pro cycling teams, but it's not going to be something that would be impossible to overcome by just buying several more tyres to have the desired range of properties available for the conditions of any given race.

Regardless, this will be an interesting space to follow in the future.

Ah, OK. I was more thinking of mountain biking and related stuff. I didn't know that punctuation of tires still is a thing in (street) cycling.

However, I assume an airless tire for biking should have the same round cross section like an air filled bike tire, while the car tires both have a rectangular cross section. Thus the tires for biking need to be constructed differently. The one I've found is from Schwalbe and is basically a usual tire filled with a PU having a similar stiffness than a common tire with an air pressure of 3.5 bar. Currently, they don't have a system for racing yet.
