„This refers to “Governing uncertainty in geoengineering” (April 23). Experiments with atmospheric and natural forces are more dangerous than containing and repairing damage. „

„Games could reveal systemic shortcomings in current frameworks, they could deepen the role of citizens in day-to-day governance mechanisms, and even improve the workings of major UN bodies. They could trigger new ways of approaching unfamiliar problems, and harness the power of creative thinking to develop new solutions for the world’s greatest challenges.“

„Large-scale climate geoengineering will probably be required to limit warming to well below 2 °C, in line with the 2015 Paris Agreement. While geoengineering has long been included in the development of many (future) low-carbon emissions pathways, key questions remain about the efficacy and ability of such climate intervention to fulfil its anticipated role in limiting warming. As such, the social license for geoengineering has not been granted for research using unbounded large-scale experiments, never mind full-scale deployment.“
„Instead the researchers homed in on the idea of marine cloud brightening—a form of solar geoengineering, in that it increases the planet’s reflectivity. Spraying tiny salt particles from seawater up into the low layer of clouds that blankets much of the ocean’s surface would form cloud micro-droplets.“
„At the end of a cul-de-sac called Fresh Way, two bright green structures the size of shipping containers gleam in the warm sunlight, quietly sucking from the air the carbon dioxide that is warming the planet.“
„A cross-party group of MPs has urged the government to give its full backing to carbon capture usage and storage (CCUS). A report published by the Business, Energy and Industrial Strategy (BEIS) select committee calls on ministers to give the “green light” to CCUS, which it claims has suffered from 15 years of “turbulent policy support” in Britain.“
„The Government faces spiralling climate change costs unless it accelerates plans to fund a new breed of carbon capture projects by the mid-2020s, according to MPs. A select committee report warned that without carbon capture the cost of meeting the country’s[nbsp]legally-binding climate targets will double to 2pc of GDP by 2050.“
Healthy Climate Alliance: Climate Experts Applaud Congressional Action to Restore Safe & Healthy Climate
„At Healthy Climate Alliance’s first-ever congressional briefing on Climate Restoration, climate experts from the private and public sector applauded the leadership of Congressman Jamie Raskin (MD-08) for introducing a House Resolution on Climate Restoration.„
BiofuelsDigest: Earth Day 2019 – A look at carbon negative and carbon capture technologies, advancements, and possibilities
„Some people celebrate Earth Day by planting a tree, but how about planting hemp or miscanthus instead? Both are considered carbon negative crops and very promising for biofuels, bioplastics, biochemicals, and many other biobased products for today’s world.“

„The United Nations painted a dire picture of humanity’s future in its recent climate report (IPCC 2018). It warned that failing to act on carbon dioxide (CO2) emissions will lead to vanishing sea ice and melting glaciers, increased storm events, and ports and islands at risk due to rising sea levels. The report was sobering to many, but not to scientists tasked with developing solutions to climate change.“
