La Niña could return, threatening global crops

The World Meteorological Organization (WMO) said that the La Niña phenomenon could begin to affect global weather patterns as early as September, with temperatures expected to remain above average in many parts of the world, Reuters reports.

La Niña is characterized by lower temperatures in the central and eastern Pacific Ocean and increases the likelihood of floods and droughts, which could negatively affect agricultural production.

Neutral climatic conditions have persisted since March, but they could change to La Niña in the coming months, the organization noted. According to the latest forecasts, the probability of ocean surface cooling to La Niña levels between September and November is estimated at 55%.

The WMO emphasized that seasonal forecasts and preparation for their consequences can bring billions of dollars in savings for agriculture, energy, health care and transport. In addition, timely response measures can save thousands of lives.
