Pollinator Health: The Climate Crisis Weakens Bees’ Ability to Withstand Pesticide Exposure    (Beyond Pesticides, September 13, 2023) A study published in Global Change Biology finds climate change increases bees’ sensitivity to pesticide exposure, impairing the pollinators’ ability to respond to light (Ultra-Violet UV stimuli), reducing floral syrup consumption, and lessening longevity (length of life) up to 70 percent. Notably, the reduction in floral syrup consumption indicates nutritional stress that further impacts bee species’ fecundity (productiveness), driving bee declines. Unless more is done to combat the climate crisis, the current global warming scenario increasing bees’ sensitivity to pesticide exposure will continue to threaten all pollinator health.  The study analyzes the synergistic (combined) effects of global warming and sublethal insecticide exposure in the solitary bee (European orchard bee/horned mason bee) Osmia cornuta.

Petrochemical Pesticides and Fertilizers Linked to “Shocking” Health and Environmental CrisesToday, Beyond Pesticides released a special issue, Transformative Change: Informed by Science, Policy, and Action of its journal, Pesticides and You, with a compendium of “shocking scientific findings that compel us to act in our communities, states, and as a nation and world community.” The 168-page issue documents the last year of scientific, peer-reviewed articles, policy deficiencies, and action for change that intersect not only with petrochemical pesticides and fertilizers, but with existential health crises, biodiversity collapse, and the climate emergency.  Included in the issue of reviews of published articles spanning three categories—health, biodiversity, and climate.

Glyphosate Weed Killers Reduce Crop Yields and Hamper Climate Mitigation Efforts(Beyond Pesticides, February 15, 2023) Finnish study of two separate experiments on the grass Festuca pratensis, an important forage crop grown for grazing animals throughout the world. For all experiments and plot variables, none saw glyphosate use have a positive impact on yield or biomass.   (E)ven among uncut grasses, those grown in glyphosate-sprayed soils showed the lowest root biomass. Chlorophyll content also followed this pattern, with those in the most intensively cut grouping showing the lowest content if also grown in soils where glyphosate was applied.  “This demonstrates a tremendous limitation to the potential carbon binding and storage belowground when soils are polluted by pesticide."

Pesticides & climate change: A vicious cycle (PANNA,10 November 2022)   with link to the executive summary in English, Spanish and French.   New report indicating that pesticides contribute significantly to greenhouse gas (GHG) emissions while, at the same time, climate change is expected to increase pesticide applications. It’s a vicious cycle. Real solutions: Despite these findings, the reduction of synthetic pesticide use has been omitted from climate change solutions. Instead, synthetic pesticide use has been presented as a climate change mitigation strategy by industrial agriculture interests.    The real solution addresses all sides of this vicious cycle: agroecology! The adoption of alternative agricultural systems minimizes or eliminates synthetic fertilizer and pesticide use while increasing the resilience of our farming systems to better withstand climate change impacts.
