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.

“I’ve never thought about how hot a stadium can be if it’s [synthetic] turf. [The heat] just sits there and bounces up into you,” Mailata said. “[The union] have got to bring it up. This is why we want all grass fields, to create a standard of play in the league where we’re not putting players in dangerous positions if we don’t have to.”

tires are vulcanized rubber. most modern shoes are not.

Vulcanized rubber usually refers to natural rubber from plant material. Tires are thermoset, EPDM ( ethylene propylene diene monomer). EPDM is vulcanized or cross linked with either a sulpher or peroxide based system. As are shoe soles.

Edit: the long chain polymers are cross linked not cured which changes the plastic or elastomer to a thermoset which will not melt
