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.

In recent days, Brazilian climate experts have mulled why. Some city council and mayoral candidates are financially supported by activities that profit from deforestation, such as logging and mining, Agência Pública reported. Reporters found that in several areas with high deforestation—and thus wildfires—leading politicians tended to be silent about forest stewardship.

Brazil’s largest political parties generally do not tout climate consciousness as a top issue. The party that appears the closest to doing so is the ruling Workers’ Party. Brazilian President Luiz Inácio Lula da Silva has promoted forest protection and green energy in international forums. But Lula governs in a coalition with centrist and conservative parties and has embraced fossil fuel exploration domestically.

To Angelo, a former science editor at Brazil’s newspaper of record, Folha de S. Paulo, climate was discussed so little in the campaign in part because “mainstream media tries to replicate the conversations that are happening on social media,” rather than journalists trying to orient the news cycle around policy questions.

Even worse, Agência Pública reported some time ago that a considerable number of right wing politicians (who are always pro deforestation, much like Bolsonaro) were blaming the current fires on Lula, as "revenge" for the infinite complaints about complacency and incentives that Bolsonaro and his thugs gave for deforestation

I will tell you why, because here there are two types of political ads:

1- candidates making the most vague promises possible like "I will improve our healthcare!"

2- ads throwing dirt on other candidates for whatever reason

Not a single candidate will talk about concrete plans, whether for protecting the environment nor for any other municipal issue.

Why are we talking about Brazil? /genq

Every country needs to go to zero emissions, and Brazil is big enough to matter. Its fossil fuel use has been modest, but deforestion can tip the Amazon from a rain forest into a dry savanna, killing off all the trees, and releasing the carbon they presently sequester.

Thank you for explaining!

Brazil is sharing the atmosphere with most of us, since it is on planet earth, which is a very popular planet to live on.

Quality of living is sadly declining on this planet, due to climate change.

Someone getting downvoted with a clearly marked genuine question. Damn I thought this was better than reddit
