"A call to replace problematic pesticides, and ways to measure climate changes of the past, in this week's pick from the Nature archive."
"50 years ago doi: https://doi.org/10.1038/d41586-026-00193-9 This article features text from Nature's archive. By its historical nature, the archive includes some images, articles and language that by twenty-first-century standards are offensive and harmful. Find out more."
Calls advocate replacing problematic pesticides because of ecological persistence, bioaccumulation and toxicity to non-target species, and because of risks posed to human health and ecosystems. Recommended strategies emphasize adoption of less persistent chemistries, integrated pest management, targeted biological controls and regulatory measures to phase out hazardous compounds. Methods to measure past climate change include tree-ring analysis, ice-core isotopes, lake and marine sediment stratigraphy, coral and speleothem records, radiometric and isotopic dating, and historical documentary sources. Combining multiple proxies and dating techniques yields better temporal resolution and confidence in reconstructing natural variability and long-term climatic trends.
