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.

To manage the energy crisis, the government has also ordered coal-fired power plants to operate at full capacity. In addition, it has instructed PTT Exploration and Production Public Company Limited (PTTEP), a subsidiary of state-owned oil and gas company PTT, to maximize domestic gas production in the Gulf of Thailand. Experts warn these measures threaten Thailand’s updated emissions reduction pledge under the Paris climate agreement, which commits to a 47% reduction in net greenhouse gas emissions by 2035.

Per the article, the following are the ones which work:

  • Carbon pricing and taxation (8 policies): Carbon taxes across sectors, emissions trading schemes, congestion charges and fossil fuel excise taxes all show robust effects, even when controlling for all other policies. This counters the claim that carbon pricing only seems effective because it’s usually accompanied by complementary measures.

  • Energy efficiency and standards (5 policies): Building energy codes, air emission standards, minimum energy performance standards and motorway speed limits consistently reduce emissions.

  • Renewable energy and research (11 policies): R&D expenditure on carbon capture, nuclear, hydrogen, energy efficiency and renewables, and planning for renewable expansion and auction schemes all reliably drive emission reductions.

  • Reporting and accountability (3 policies): Greenhouse gas emissions reporting requirements across sectors show significant effects.

  • Subsidy reduction (1 policy): Eliminating fossil fuel subsidies in transport reduces emissions.

Climate change is one of the main concerns of the Swiss population. However, most citizens don’t want to invest more money in the ecological transition, as shown by their rejection of the climate fund initiative on Sunday.

On Sunday 71% of voters rejected the initiative calling for up to 1% of gross domestic product to be invested annually in measures to protect the climate and nature.

As the effects of climate change worsen, more people are wondering how it’s going to affect them personally. How is temperature and weather changing where you live? Is your home at risk from natural disasters, like wildfires and floods? And how will warming affect things like the economy, energy, health, and population trends?

We’ve gone through dozens of climate risk maps to identify the 5 regions of America which are facing the most overall risk. This is a quick way to check whether you’re sitting in the line of fire, so you can take steps to mitigate (or avoid) those threats.

Jeffrey B. Clark oversaw the dismantlement of government restrictions on greenhouse gas emissions and water and air pollution. He had also faced a criminal probe in connection with the 2020 election.
