Wei-Jun Cai, an expert in marine chemistry at the University of Delaware, is sounding new alarm bells about the changing chemistry of the western region of the Arctic Ocean, where he and an international team of collaborators have found acidity levels increasing three to four times faster than ocean waters elsewhere.

Copepods are among the most important organisms in the ocean.

Desert dust was assumed to be the primary contributor to elevated air pollution across the Middle East.

Unlike organic fertilisers, which come from plant or animal material, synthetic fertilisers are made by humans using chemical processes.

August 2022 was the world’s sixth-warmest August in 143 years, according to scientists at NOAA’s National Centers for Environmental Information.

On September 14, 2022, Typhoon Muifa made landfall twice near China’s largest metropolitan area and several of the world’s major shipping ports.

In summer 2022, record-breaking heat waves in California and elsewhere have triggered a stream of health alerts and warnings, strained power grids, and left millions of the most vulnerable Americans sweating through uncomfortable and sometimes deadly conditions.

Researchers have considered how flooding from rising sea levels and storm surges will damage the built environment along the coast, but what about climate change’s less noticeable impacts below the surface?

In the absence of human intervention, most of the forests in the Amazon River basin are too wet to burn. Yet for as long as scientists have observed the region by satellite, they have detected an abundance of fire activity, especially during the driest months of the year.

The capacity of plants to bind carbon is a key factor in calculating the effects of climate change as carbon dioxide levels rise in the atmosphere.
