Scientists continue to publish new drought reconstructions indicating there were far more frequent and severe drought periods in the past several thousand years than anything observed in the modern period.
A new study (Berg and McColl, 2021) indicates there has long been “qualitatively incorrect” estimates of the impact modern and future warming has on drought trends and dryland expansion because atmospheric aridity is “not an accurate proxy of the future extent of drylands.” Consequently, the authors suggest there will be “no global drylands expansion under greenhouse warming, contrary to previous claims based on atmospheric aridity.”
Indeed, instead of being driven by increasing greenhouse gas concentrations and warming, droughts along the western coast of the United States are “predominantly [84%] driven by internal atmospheric variability” and cooling sea surface temperatures (Baek et al., 2021).
