Solar geoengineering study could offer a quick fix for climate change

Scientists from Harvard University in the United States are launching the biggest solar geoengineering programme to date, with a view to study the effects of this technology as a potential fix for global warming. The project due to take off in a few weeks consists of spraying sulphate aerosols about 20 kilometres in height into the Earth’s stratosphere.

How ocean warming will kill fish, make them smaller and potentially toxic

How ocean warming will kill fish, make them smaller and potentially toxic

Ocean warming, driven by increasing carbon emissions and rising temperatures, may become one of the biggest challenges facing humanity and threatening the Earth’s life systems, affecting even those living far from oceanic coasts. Already impacting people, fish stocks and crop yields, it may lead to more extreme weather events and increased risk from water-borne diseases including cholera. Fuelling

Australia’s Great Barrier Reef with its multi-coloured biodiversity, Madagascar’s rainforests with their lemurs, Tanzania’s natural reserves, and Szechuan giant panda sanctuaries in China. These and many others natural and cultural treasures are at risk due to human-related economic activities. A report carried out by WWF shows that at least 114 out of 229 World Heritage
