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.

Apologies, I meant that I wanted to know how they came to the conclusion that climate could be affecting the prevalence. I'm not denying their claim, just curious what evidence they have.

I may have missed your quoted section because I opened the link on mobile and couldn't stand how disruptive the page was without ad block.

A shit you made me read it again too and they also say that

“I think the way to think about how global warming is putting selection pressure on microbes is to think about how many more really hot days we are experiencing,” said Casadevall of Johns Hopkins. “Each day at (100 degrees Fahrenheit, or 37.7 degrees Celsius) provides a selection event for all microbes affected — and the more days when high temperatures are experienced, the greater probability that some will adapt and survive.”

Idk, not a scientist. Seems like one of those complex chain reaction things, not a question of direct evidence for a single causing factor. Most of that stuff prefers warm temperatures and humid environments. Water from floods for example is full of delicious food for all kinds of organisms that can harm us. Also possible that the warming and seasonal weather extremes will speed up their evolution and make them generally stronger. Then combine that with the growing antibiotic resistance, and even weak and lame stuff like legionella will very soon be a greater danger.
