Without solar geoengineering to deal with climate change, will Earth inevitably become inhabitable? The hugely controversial, if probably inexpensive, proposal — to cool the planet by using aerosols or other methods to reflect away some of the Sun’s radiation — defines economist Gernot Wagner’s thought-provoking study. Two decades ago, he considered the idea “nuts”. He still does, but today he advocates extensive new research and thinks we have to take the “gamble”, despite the risks. The issue is now “not if, but when”.
Deutschland hat es versäumt, eine konsequente Energiepolitik für die Zukunft zu machen. Stattdessen lähmt eine übervorsichtige Industriepolitik den Wandel. So bleibt man abhängig – von China und den USA.
