2023 is over, and the climatic imprint it left on the world is particularly bad. The list of climatic disasters of 2023 is long, and the year included the hottest single day, the hottest ever month, and probably the hottest December. The Biden administration and activists in favor of sweeping action on climate change have touted offshore wind as a green energy lynchpin of their envisioned fossil fuel-free future, but this year’s results were not stellar for those interests. The time for concerted action was in 2000, not 2024. 2023 marked the end of the prelude to climate change and the beginning of the new reality of an overheated planet. 2023 will go down as the hottest year on Earth in 120,000 years, marking a point when humanity crossed into a new climate era.
