That’s set to increase temperatures below the surface, which then may raise sea-surface temperatures further in the coming months, it said in a fortnightly update.

Tropical commodities including palm oil are to be favored over other raw materials such as gold and copper this half as the El Nino raises risks, according to Oversea-Chinese Banking Corp. FULL REPORT
