Injecting pollutants into the atmosphere to reflect the sun would be extremely dangerous, but the UK is funding field trials

Some years ago in the pages of the Guardian, we sounded the alarm about the increasing attention being paid to solar geoengineering – a barking mad scheme to cancel global heating by putting pollutants in the atmosphere that dim the sun by reflecting some sunlight back to space.

In one widely touted proposition, fleets of aircraft would continually inject sulphur compounds into the upper atmosphere, simulating the effects of a massive array of volcanoes erupting continuously. In essence, we have broken the climate by releasing gigatonnes of fossil-fuel carbon dioxide, and solar geoengineering proposes to “fix” it by breaking a very different part of the climate system.

My homeplace has experienced four natural disasters in eight years. But I’d never seen the like of this bird before, vibrantly green and startlingly beautiful

We were midway through our cyclone preparation when my mother broke her leg. She stepped into her bedroom to retrieve something, tripped and fell, and that was that. My mother is 74 and hardy, so this sudden break took us by surprise. Once I got her home, leg in brace, we’d lost significant time, and my household was down to one functional human: me.

This is the fourth natural disaster I’ve experienced in the last eight years. One-in-100-year floods (2017), unprecedented bushfires (2019), one-in-1,000-year floods (2022) and now Cyclone Alfred. Cyclones are a new threat. I’ve lived in my homeplace, in northern New South Wales, for almost 50 years and we’ve never had a cyclone cross land in our vicinity. We were, as they say, in uncharted waters.
