Historian, journalist, and author of the prescient book Climate Wars Gwynne Dyer tracks down the world's top climate engineers to try to answer the question: what can science do to mitigate the catastrophic and irreversible effects of climate change?The fact that there is a global climate emergency is no longer up for debate. And if we are unable to get our emissions under control, what options are left? It's a subject that we will have to understand, as scientists, politicians and concerned citizens scramble for a solution to the catastrophic effects of a warming world. For decades, discerning readers have turned to journalist and historian Gwynne Dyer for his unparalleled acumen in serving up hard geopolitical truths. Intervention Earth is built around Dyer's interviews with sixty climate scientists from around the globe, including the leading figures in the geoengineering field. One of the main topics: the pros and cons of Solar Radiation Management, a possible planetary Hail Mary that is rife with political risks. Intervention Earth is not just about this or that technological mega-project. Dyer devotes ample space to the many innovative ideas on offer, but there is no get-out-of-jail-free card. We will need a whole portfolio of techniques and technologies -- and a lot of hard, thankless work -- to keep the planet hospitable for humanity. What's more, many of the technologies that can help us avoid the worst outcomes require years of investment and development before they can be successfully deployed. Global cooperation will be key in implementing the life-saving strategies outlined in the book. Intervention Earth offers a probing and eye-opening look at the problems facing us, and the innovations that just might keep us ahead of encroaching disaster and carry us to a safe harbour.
