WASHINGTON - A brewing “Super” El Nino cycle is poised to unleash heat waves, floods and drought worldwide, with the effects amplified by long term human-caused climate change.But what if it was possible to interrupt and effectively “switch off” the Pacific Ocean heating phenomenon as it starts to form?That’s the premise of a new Science Advances study published on July 8, which uses computer models to show that artificially brightening clouds over the Pacific, when timed right, could neutralise the influential weather pattern and blunt its worst impacts.While previous research on so-called geo-engineering has focused on cooling the planet as a whole, the new paper instead proposes more targeted interventions.“These shorter timescales of interventions could be a very powerful way that geoe
