Global aridification crisis deepens

Over the past three decades, an expanse of land substantially larger than India has transformed from humid to dryland, with drylands now constituting 40% of the Earth’s surface, excluding Antarctica. This shift towards global aridification has had profound implications, with the UN Science Policy Interface reporting that three-quarters of the world’s land experienced drier conditions …

Revolutionizing geophysics with DAS technology

Caltech researchers have unveiled a groundbreaking method to probe the deep structure of the Earth, particularly at the Mohorovičić discontinuity, known as the Moho. This method employs the advanced technology of distributed acoustic sensing (DAS), akin to performing an ultrasound on the Earth. Their study, detailed in Science Advances, capitalizes on how seismic waves from …

Cloud cover and the albedo effect

Last year set a grim record as the hottest year ever documented, with unprecedented ocean temperatures and accelerated glacier melts, prompting a scramble among scientists to determine the underlying causes. While the primary suspects included the usual culprits—greenhouse gas emissions from fossil fuels and the natural El Niño phenomenon—these factors alone could not fully account …
