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.

If you want to hit climate targets, it's extremely important

To have any hope of meeting the central goal of the Paris Agreement, which is to limit global warming to 2°C or less, our carbon emissions must be reduced considerably, including those coming from agriculture. Clark et al. show that even if fossil fuel emissions were eliminated immediately, emissions from the global food system alone would make it impossible to limit warming to 1.5°C and difficult even to realize the 2°C target. Thus, major changes in how food is produced are needed if we want to meet the goals of the Paris Agreement.

you misunderstand, what I'm saying is I think that it's a wasted effort to split your concentration the way it is being done, the agricultural industry is going to be one of the most resistant changes out there, the other Industries such as manufacturing and oil, you have your lesser groups that are not going to be impacted so it's going to be fairly easy to gain support for those groups, however with the agriculture industry there is a vast more people that are going to be out to disregard the entire study because they won't want to change their lifestyle. You can have all the statistics in the world however at the end of the day those deciding actors are generally decided by the general public who isn't going to bother looking at complicated statistics. So therefore it would be a better move to go towards the path of least resistance which is going to be the other top emitters. My opinion is that if reducing the top three emitters somehow makes it so you don't hit your climate goal, the climate goal isn't going to be feasible to hit in the first place.

This isn't me saying that it shouldn't happen I'm just saying that the changes posted won't happen all at once and likely won't happen at all if too many Focus points are attempted at once.

I don't think the goal is feasible, but I would love to be proven wrong

There already is momentum in the right direction in many countries such as Germany. I don't think it's a hopeless fight at all

In 2011, Germans ate 138 pounds of meat each year. Today, it’s 121 pounds — a 12.3 percent decline. And much of that decline took place in the last few years, a time period when grocery sales of plant-based food nearly doubled.

The global food systems biggest carbon source is from fertiliser production
