Climate Change, Not Rain Shortage, Drives Severe Western Droughts

Monthly relative anomalies demonstrate the spatial development of chlorophyll-a concentration, a proxy for phytoplankton biomass, during December 2019. Relative anomalies are expressed as the percentage above the monthly climatological mean, relative to the period January 1998–December 2020.

Study suggests US droughts, rainy extremes becoming more severe

This map shows how the average incidence of Valley fever varies across different counties, with yellow and green representing higher incidence than blue and purple.

California Droughts Fuel Surge in Dangerous Airborne Fungal Disease

A center-pivot irrigation system waters a cornfield near Adams, Nebraska, about 45 minutes south of Lincoln. A new Husker-led study shows how the depletion of groundwater — the same that many farmers rely on for irrigation — can threaten food production amid drought and drier climes. Due in part to the challenges of extracting groundwater, an aquifer’s depletion can curb crop yields even when it appears saturated enough to continue meeting the demands of irrigation, the study found.

Study quantifies how aquifer depletion threatens crop yields

Five consecutive rainfall season failures in the Horn of Africa caused the region’s worst drought in 40 years (with Ethiopia, Kenya and Somalia particularly hard hit), contributing to reduced agricultural productivity, food insecurity and high food prices (WMO, 2023)

Drought data shows “an unprecedented emergency on a planetary scale”
