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'll be taking a bus to a swing state to help elect Harris this coming weekend. You don't need to do quite that much; there are actions hosted near you to join.

The reason is that while Harris isn't in absolute 100% agreement with me on every detail (unless I run for office, no candidate will be), she's the candidate much closer to taking adequate climate action. The Biden/Harris administration did a lot, starting with Harris casting the deciding vote for the Inflation Reduction Act., a key piece of climate legislation. We even saw major cuts to the leasing of federal lands for coal, as well as big cuts to oil and gas leasing

By contrast, Trump appointed a coal lobbyist to run the EPA and took steps to increase not just greenhouse gas emissions, but a wide variety of human-impacting pollutants, and surrounded by people who want to eliminate any effort to address the climate problem

The procession moved towards the Ministry of Justice where they then blocked the road for 90 minutes of silence while posters were held up, displaying images of activists who are currently imprisoned. A choir then sang as they marched towards a green where names of political prisoners were read out.

While wind is more expensive than solar, and has issues highlighted in article, the higher capacity factors, and production outside of midday, means less battery capacity is needed to serve renewables, and batteries get charged more often.

A key to bringing down transmission costs for wind, especially offshore where transmission is the highest cost component, is hydrogen production. Picking up H2, or refueling, by trucks and ships can provide cheaper energy than transmission lines. Pipelines are even cheaper with enough volume, and double as storage.

The consequences will be even more catastrophic without urgent action. The water crisis threatens more than 50% of global food production and risks shaving an average of 8% off countries’ GDPs by 2050, with much higher losses of up to 15% projected in low-income countries, the report found.
