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.

Burning wood for power worse for climate than gas equivalent (www.theguardian.com)

The key problem is that they cause deforestation:

Bio-energy with carbon capture and storage (BECCS) has been touted as a clean way of producing baseload power, substituting for gas and coal, which could even result in “negative emissions” as when replacement forests are grown they take up CO2 from the air.

But such systems could take 150 years to be “carbon negative”, researchers from the US, UK and China have found, in part because of the long time it takes to regrow forests, and because of the damage done when existing savannah, pasture or cropland is converted to grow biomass for burning.

(This is unrelated to the argument discrediting I'm about to do: usually journal entries like this are called "articles"; manuscripts are hand- or typewritten. This does not detract from your argument; I just wanted you to know.)

I'm going to trust four expert researchers writing in 2026 for one of the most academically prestigious journals on Earth over some random social media user who can't even spell "CO2" and categorically did not read the article (it's closed-access, and you're offering no specific critiques). I'd doubt you even read the abstract given how generic this half-baked critique is. Sorry to say that I only read a preprint which isn't exactly reflective of the full, closed-access article, but you're just authoritatively spouting made-up bullshit about a field you clearly have zero understanding of and probably haven't ever read a single peer-reviewed paper in.

And literally what the fuck do you mean "especially at that journal"? That journal is one of the best ones there is.
