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.

Saved you a click:

the 1930s were the decade of the Dust Bowl — the grim result of relentless overplowing of the Great Plains followed by natural oceanic cycles that favored a multiyear drought, which coincided with the Great Depression.

The heat was localized to one continent. See their pic for world comparison (open in new tab for bigger version):

The article is a worth a read, answers the question in the first couple paragraphs, and isn't a site flooded with ads. You're just saving people from learning more than the answer to the headline

Click-bait headlines should always be punished. More particularly, re-posting click-bait headlines without explaining the answer in the body must be condemned.
