An unexpected mystery has appeared at the equator in the Atlantic Ocean, in the form of a sudden cooling trend in the surface waters, despite the ongoing record-breaking warming of the ocean surface and a lack of the conditions that would typically be required for La Niña-like conditions to formread more
The 2023 hurricane season in the North Atlantic is ramping up with a record number of tropical storms underway, with no less than four systems having formed within the span of two days. This follows in the wake of the Pacific’s Hurricane Hilary making a rare track up through the Bajaread more
