And this species is just the latest to feel the impact of climate change. A report last year published by the World Wildlife Fund for Nature found that out of nearly 32,000 animal populations worldwide, there was an average decline of 69% since 1970. That sharp decline, the report warned, is a "code red for the planet (and humanity)."

"The message is clear and the lights are flashing red," WWF International's director general Marco Lambertini says in the report. "Our most comprehensive report ever on the state of global vertebrate wildlife populations presents terrifying figures: a shocking two-thirds decline in the global Living Planet Index less than 50 years."

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.
