For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.

    If any of you give a shit about the environment or animals, go vegan.

    Going vegan is the single biggest thing you can do to reduce your carbon footprint. apart from unaliving yourself.

          That’s the opinion of one of the authors of the study. it is not a substantiated by the study itself.

            Its not just one. This is pretty common knowledge among people in their field. These are specialists in their field, their opinions don’t just come from nothing, they are informed by information from the studies.

              your first link doesn’t speak to your claim at all. your second link depends on the same author.

                Here’s a link to the research article itself with all the data from which they drew their conclusion: https://josephpoore.com/Science 360 6392 987 - Accepted Manuscript.pdf

                  they are misusing the LCA data. since it was gathered through disparate methodologies, it can’t be combined as they have done.

                  edit: regardless, this paper doesn’t support the claim you made.

                    They aren’t, but I don’t feel like going into it with you. I will use a simpler data-point to prove that my initial claim was correct.

                    Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions. If everyone went vegan, that would remove the majority of greenhouse gas production. So put simply, it would be the “biggest” thing everyone could do to reduce CO2 emissions.(That is just CO2, there are many other horrible things related to animal agriculture.)

                    Here you go, this one does. and it’s peer-reviewed.

      Going vegan is a relatively small difference from going vegetarian, which is a small difference from just drastically cutting back on meat. The big thing is that our current systems are unsustainable for animal rights and the environment and everyone needs to cut back on meat drastically at the least. But I imagine that if you could stop driving a car entirely, that would be a bigger difference than losing a reasonable amount of meat from your diet. Though, cutting back on meat is an important step that all of us can take with much more ease.

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:
