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.

Major oil companies have in recent years made splashy climate pledges to cut their greenhouse gas emissions and take on the climate crisis, but a new report suggests those plans do not stand up to scrutiny.

The research and advocacy group Oil Change International examined climate plans from the eight largest US- and European-based international oil and gas producers — BP, Chevron, ConocoPhillips, Eni, Equinor, ExxonMobil, Shell and TotalEnergies — and found none were compatible with limiting global warming to 1.5C above pre-industrial levels — a threshold scientists have long warned could have dire consequences if breached.

The report’s authors used 10 criteria and ranked each aspect of each company’s plan on a spectrum from “fully aligned” to “grossly insufficient” and found all eight companies ranked “grossly insufficient” or “insufficient” on nearly all criteria.

The authors also found that the companies’ current oil and gas extraction plans could lead to more than 2.4C of global temperature rise, which would probably usher in climate devastation. The eight firms alone are on track to use 30% of the world’s remaining global carbon budget to keep global average temperature rise to 1.5C, the study found.

The report, in its fourth annual edition, was endorsed by more than 200 climate groups internationally. Since the first edition of the report in 2020, many oil companies have rolled back climate pledges amid spiking fossil fuel prices.“ The Big Oil Reality Check data illustrates these companies’ dangerous commitment to profit at all cost,” said Tong. It follows a March report from the thinktank Carbon Tracker, which found none of the world’s 25 largest fossil fuel companies’ production and transition plans align with the central goal of the 2015 Paris climate agreement.

Lies and denial about the impact of the O&G industry are so PERVASIVE in today's society, I think it's important to scientifically study and report on the reality of their impacts on this planet. We'll be talking about for the next 100 years
