We find that so-called “sustainable” aviation fuels are largely a false solution.

Including an exceptionally warm Northern Hemisphere (NH) summer1,2, 2023 has been reported as the hottest year on record3-5. Contextualizing recent anthropogenic warming against past natural variability is nontrivial, however, because the sparse 19th century meteorological records tend to be too warm6. Here, we combine observed and reconstructed June-August (JJA) surface air temperatures to show that 2023 was the warmest NH extra-tropical summer over the past 2000 years exceeding the 95% confidence range of natural climate variability by more than half a degree Celsius. Comparison of the 2023 JJA warming against the coldest reconstructed summer in 536 CE reveals a maximum range of pre-Anthropocene-to-2023 temperatures of 3.93°C. Although 2023 is consistent with a greenhouse gases-induced warming trend7 that is amplified by an unfolding El Niño event8, this extreme emphasizes the urgency to implement international agreements for carbon emission reduction.

Recently I have been on a four-day hiking trip, completing another 80 km (~50 mile) stretch of the 1171 km National Blue Trail running across my tiny country. This gave me plenty of time to tune into and ponder on the many podcasts I downloaded previously, but never had the time to listen to.

Stratocumulus cloud decks—which cool the Earth’s surface by shading it from sunlight, and are prevalent in the subtropics—break up into scattered clouds when CO2 levels rise above 1,200 ppm in large-eddy simulations that explicitly resolve cloud dynamics.

The Paleocene–Eocene boundary coincided with runaway global warming possibly analogous to future climate change, but the sources of greenhouse gasses have remained unresolved. Here, the authors reveal volcanism triggered initial warming, and subsequent carbon was released after crossing a tipping point.

Demonstration of high performance, upscaling and integration of ultra-lightweight perovskite solar cells are still rare. Hailegnaw et al. develop 2D perovskite solar cells based on methylbenzyl ammonium iodide with improved specific power and stability, showing scalability and integration in drones.
