  • A study expands upon the international Earth heat inventory from 2020, which provides a measure of the Earth energy imbalance (EEI) and allows for quantifying how much and where heat has accumulated in the Earth system with comprehensive data. It suggests that the EEI is the "most fundamental global climate indicator" to gauge climate change mitigation efforts.
• 18 April
  • Astronomers conclude that "... planets in the habitable zones of stars with low metallicity are the best targets to search for complex life on land."
  • A university reports a study (29 Mar) affirming the high level of economic losses from biological invasions, showing they have risen to the level of economic damage costs from floods or earthquakes, which are also rising.

It indicates meeting the 1.5 °C goal would decrease the population exposed to unprecedented heat ~5-fold and ties itself to earlier research by initially noting that quantifying the social cost of carbon in monetary terms, as related or economics studies tend to do, may be inadequate.
• Шаблон:Vanchor
  • Using the Hubble Space Telescope and Gaia spacecraft, an analysis of proper motions of the closest known globular cluster, Messier 4, reveals an excess mass of roughly 800 solar masses in the center. This appears to not be extended, and could thus be the best kinematic evidence for an intermediate-mass black hole (even if an unusually compact cluster of compact objects, white dwarfs, neutron stars or stellar-mass black holes cannot be completely discounted).

  • One of the first empirical studies on what real users are shown during their typical use of popular Web search engines interprets its results to show that choices for unreliable news sources for their queries are driven primarily by users' own choices and less by the engine's algorithms. The Web scientists link their findings to the concept of filter bubbles which emphasizes the role of design- and personalization algorithms. On 2 May, a report accompanied by an open letter concludes that Alphabet Inc, against its voluntary promises, still runs climate misinformation ads.
