An international team of scientists spent three months at sea drilling into a huge, mysterious reservoir of freshwater under the salty ocean. They hope it could help tackle an increasingly severe global water crisis.

Three factors are to blame, or cheer. One, a strong vertical wind shear, which refers to a change in wind speed or direction with altitude. It has increased thanks to a cyclonic circulation in the mid-upper troposphere, which is the lowest region of the Earth’s atmosphere.

A system in the Atlantic could possibly become Tropical Storm Gabrielle — or even a hurricane — near the Caribbean next week. It could pose a threat to Florida or elsewhere on the US coast.

When Hurricane Erin explosively intensified in the Atlantic, the alarming part wasn’t solely how dangerous it had become as a Category 5 monster: It was also just how typical such an ultra-rapid rate of intensification has become.

The first area is a broad area of low pressure and organized storms that is moving W/NW across the Atlantic Ocean. As this area continues to move across the Atlantic Ocean, it will enter move favorable environmental conditions that will help further the potential for tropical development.

Since 2011, a monstrous structure has taken shape in the Atlantic Ocean almost every year, sprawling from the West African coast to the Gulf of Mexico. It’s the Great Atlantic Sargassum Belt—a gargantuan bloom of a brown free-floating seaweed. In May, the seaweed belt hit a record biomass of 37.5 million tons.

Deep in the heart of Central Asia, the Kunlun Mountains form a vital barrier on the northern Tibetan Plateau. Their rainfall is a lifeline, feeding the oases and rivers of the arid Tarim Basin. While scientists have mapped the region's basic climate patterns,

Researchers have discovered freshwater in the most unlikely of places, underneath the Atlantic Ocean. But can it be tapped?
