But another recognisable feature of the Emerald Isle, is its lush green vegetation, a product of the island’s mild climate and frequent rainfall. It was on a rare sunny day of a ...[Read More]
Geosciences Column: Human-induced changes in the ocean’s salinity and temperature fields
In this month’s Geosciences column, Mona Behl discusses a recent paper on the effects of anthropogenically-induced climate change on the planet’s oceans. A recent study led by scientists at the Scripps Institute of Oceanography, University of California San Diego, suggests that observed changes in ocean salinity are inconsistent with natural climate variations and can be attributed to human ...[Read More]
