The world鈥檚 average temperature has increased 1掳C in just the past 100 years. Extreme weather and rising seas are already causing global unrest, and many scientists believe that if we cannot curb planetary warming, it could pose an existential threat to human civilisation.

As it becomes clear that emissions reduction alone may not be enough to avoid the dire effects of climate change, a growing collective of scientists and engineers is developing technologies that could cool the planet. These range from geoengineering our atmosphere to reflect sunlight, sucking carbon dioxide right out of the air, to enlisting forests to do the job for us.

Tha teothachd chuibheasach na cruinne air 猫iridh 1掳C sna 100 bliadhna a dh'fhalbh. 'S e adhbhar dragha a th' ann am f矛or dhroch-sh矛de agus 脿rdachadh cuain, agus tha m貌ran luchd-saidheans dhen bheachd mura cur sinn bacadh air bl脿thachadh na cruinne gum bi s矛obhaltas mhic an duine ann an cunnart. Mar a tha e a' f脿s follaiseach nach cuir l霉ghdachadh truaillidh a-mh脿in bacadh air cron ri linn atharrachadh na gn脿th-sh矛de, tha co-chruinneachadh de luchd-saidheans is innleadairean a' leasachadh teicne貌las airson an t-saoghal fhuarachadh 鈥� bho bhith ag atharrachadh an 脿ile airson frith-thilgeil solas na gr猫ine, gu bhith a' tarraing carbon d脿 ogsaid 脿s an 猫adhar, gu bhith a' cleachdadh choilltean.
