CO₂-removal News

„There are some people who want to put the Anthropocene on steroids by asserting human control over these changes – here I am thinking of those who believe we can geo-engineer the climate system, for example by constructing machines to inject aerosols and particles into the upper atmosphere to help block sunlight. Aside from the risks and uncertainties associated with such technologies, they would demand governance institutions of a global scope and longevity of a sort unprecedented in human history.“

„When we are told shipping has a vital role to play in counteracting the effects of global warming, eye rolls usually ensue – but far from a further ratcheting on the emissions performance clamp, a new study suggests altering the wake behind vessels with smaller and more reflective bubbles.„

„The scientists had whipped themselves into a frenzy. Gathered in a stuffy conference room in the bowels of a hotel in Berlin, scores of respected climate researchers, mostly middle-aged, mostly white, and mostly men, were arguing about a one-page document that had tentatively been[nbsp]christened the[nbsp] ​“Berlin Declaration.”[nbsp]It proposed ground rules for conducting experiments to explore how we might artificially cool the Earth—planet hacking, basically.“

„As peachy as it sounds, climate hacking runs[nbsp]into two problems: first, an affordable and well-understood solution to climate change already exists, and second, geoengineering poses massive risks. Out of the methods that can be used for climate hacking, solar radiation management is a favorite, which also happens to be the most dangerous as well.“

„With[nbsp]urban populations expected to continue growing, cities’[nbsp]exposure to climate change[nbsp]will only get worse unless[nbsp]they[nbsp]break away from[nbsp]this GHG-emitting[nbsp]status quo. Fortunately, the emerging field of carbon dioxide removal (“CDR”) offers hope.“

„Welcome to the first annual edition of the Everything and the Carbon Sink carbon dioxide removal (“CDR”)[nbsp]New Year’s[nbsp]review/preview post! This post highlights my take on the most significant advances[nbsp]in the CDR field from the past year, and my expectations for how the field might develop[nbsp]in 2015.“

„There are two problems with this argument. The first is that we already have an affordable solution with a relatively well-understood outcome: reducing our carbon emissions. The second is that geoengineering itself is fraught with danger and that, worryingly, the most dangerous version, called solar radiation management, is also the most popular with those exploring this field.“
