Climate Change Stings Honey Bees: Less Honey, Higher Temps
8 Sep
Summary
- Extreme heat reduces bee foraging and increases hive cooling needs.
- Earlier springs cause plant blooms to mismatch bee activity periods.
- Drought and heavy rains reduce nectar availability for bees.
September marks National Honey Month, but climate change is casting a shadow over honey production. Rising global temperatures, sea level changes, and intensified weather events are directly affecting honey bees in regions like Georgia and South Carolina.
Extreme heat reduces bees' foraging time and forces them to expend more energy cooling their hives. Warmer temperatures also lead to earlier plant blooms, creating a 'phenological mismatch' where bees miss vital food sources. Drought conditions diminish nectar production, and intense rainfall events prevent bees from foraging altogether.
Warmer winters can also inadvertently aid pests like Varroa mites, a major threat to bee colonies. These combined climate impacts affect bee health, foraging patterns, and ultimately, the quantity and quality of honey produced, posing challenges for beekeepers and the pollination cycle.
