Politicians often speak of climate change as a problem for future generations to solve, but many scientists say the time to act is now and that the climate has already changed — it's not a far-off scenario.

Here are some of the main ways 2023 became a defining year in our anthropogenic spiral to the bottom, but with our constantly shifting baselines, it's not likely to be an anomaly.
