El Nino's Return Brings Threat of Extreme Weather and Climate Impacts.

The El Nino climate pattern has returned, bringing the threat of extreme weather conditions worldwide, including tropical cyclones, increased rainfall, and flooding in parts of the Americas, rising temperatures globally, and droughts in Australia. The economic impact of this year's El Nino could lead to global losses of $3 trillion, with agricultural production and manufacturing being severely affected.
