Omg these comments are annoying! Yes! We know you think we know this. But this specific part has now been proven with data, rather than just anecdote or assumption based on other studies.

"While climate models have predicted that this variability will increase with future warming, this study confirms that this pattern has already emerged over the past century.

By analyzing a wide range of observational data, the researchers found that rainfall variability has increased since the 1900s over 75% of the land areas studied, particularly in Europe, Australia, and eastern North America. The researchers found that daily rainfall variability has increased globally by 1.2% per decade."

Maybe we need a few more studies to decide if it’s our fault before we do anything about it

We know. Well, most of us do.

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.
