Research portending the greater frequency of back-to-back La Niña events under future greenhouse-gas emissions scenarios is among the items featured today on the Scimex website.
A 33% increase in those events is predicted for a high-greenhouse gas emissions scenario, according to Australian and international research.
The study found that under a high emissions scenario, the frequency of multi-year La Niña increases from one event every 12.1 years in 1900–1999 to one event every 9.1 years in 2000–2099.
The authors say their finding of a probable future increase in multi-year La Niña frequency strengthens calls for an urgent need to reduce greenhouse-gas emissions to alleviate the adverse impacts.
