Climate engineering off US coast could increase heatwaves in Europe, study finds
This is an issue that never occurred to me and would not take notice but is a front page article in the US oriented version of The Guardian today.
Climate engineering off US coast could increase heatwaves in Europe, study finds
Scientists call for regulation to stop regional use of marine cloud brightening having negative impact elsewhere
A geoengineering technique designed to reduce high temperatures in California could inadvertently intensify heatwaves in Europe, according to a study that models the unintended consequences of regional tinkering with a changing climate.
The paper shows that targeted interventions to lower temperature in one area for one season might bring temporary benefits to some populations, but this has to be set against potentially negative side-effects in other parts of the world and shifting degrees of effectiveness over time.
The authors of the study said the findings were “scary” because the world has few or no regulations in place to prevent regional applications of the technique, marine cloud brightening, which involves spraying reflective aerosols (usually in the form of sea salt or sea spray) into stratocumulus clouds over the ocean to reflect more solar radiation back into space.
