„Machines that suck CO2 directly from the air could cut the cost of meeting global climate goals, a new study finds, but they would need as much as a quarter of global energy supplies in 2100.“
„Scientists seeking to avoid catastrophic sea-level rises from the melting West Antarctic ice sheet have come up with a ‚terrible‘ solution: use snow cannons to pump trillions of tons of ice back on top.“

„There is evidence that a self-sustaining ice discharge from the West Antarctic Ice Sheet (WAIS) has started, potentially leading to its disintegration. The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo. Here, we show that the WAIS may be stabilized through mass deposition in coastal regions around Pine Island and Thwaites glaciers.“
„In the early 1990s, the European Space Agency launched a technology to extend space missions by filtering exhaled[nbsp]CO2 out of the air on board of shuttles and space stations. During the past two decades, the technology[nbsp]–[nbsp]known as Direct Air Capture[nbsp](DAC)[nbsp]–[nbsp]has been further developed, but in a different context: researchers are considering the technology as a means to remove[nbsp]CO2 or other greenhouse gases from the earth’s atmosphere.“

„Vast snow cannons could be used to repair the West Antarctic ice sheet and prevent catastrophic sea level rise, leading climate scientists have suggested.“
„Climate economist Dr. Gernot Wagner discusses how solar geoengineering can be a major solution to climate change. He considers Carbon taxes versus carbon taxes and talks about the issue of uncertainty as we find creative, market-based fixes for our warming planet.“
„The UK recently adopted a legislative 2050 target for ‘net-zero’ climate-changing emissions. Other countries are also moving towards similar goals. Such targets are hugely welcome in the face of growing climate change impacts. Yet delivering ‘net-zero’ depends not only on accelerated mitigation, but also critically on the development and deployment of carbon removal techniques. This creates something of a dilemma.“
