big think: Geoengineering Gets Closer to Fighting Climate Change
„In his Big Think interview,[nbsp]Bill Chameides, dean of Duke’s Nicholas School of the Environment, says plans for humans to control the global climate are premature. „

„A study into reversible geo-engineering method to offset rising global temperatures has narrowed in on an energy efficient method of cloud brightening. The „Rayleigh Jet“ technique could help offset the effects of carbon emissions at the expense of 30 megawatts of energy.“

„We derive analytic expressions of the transient response of the hydrological cycle to surface warming from the surface energy balance in which turbulent heat fluxes are constrained by the thermodynamic limit of maximum power.“
„The Earth faces an imminent crisis caused by runaway Arctic warming. So says climate campaigner John Nissen, who travelled to COP20 in Lima to impress the dangers on delegates – and urge them to emergency action to cool the Arctic before it’s too late.“

„In the debate on climate change, there are two competing catastrophisms: one is emancipatory catastrophism, coined by Ulrich Beck; and the other is what the author of this article calls apocalyptic catastrophism – the dystopian imagination of the future climate and a discourse serving to feed the idea of a ‘techno-fix’, namely geoengineering the Earth’s climate.“
Article on COP in Lima with a commentary on CE. „This is a theoretical ‘Plan B’ to address climate change if governments fail to legislate and enforce measures to adequately reduce greenhouse gas emissions. Some corporations see geo-engineering as a convenient means for increasing their profits.“
„In a recent column for Project Syndicate, Lili Fuhr and Niclas Hallstrom rail against carbon capture and sequestration (CCS) and carbon dioxide removal (CDR) technologies, counting them among the[nbsp]group of “ineffective or impossible” solutions[nbsp]to climate change. The sad reality is that today, Fuhr and Hallstrom’s conclusion is not that far from the truth for most most CDR solutions, which are not cost-competitive and/or technically-proven compared to other GHG abatement approaches.“
„Neither blocking sunlight nor capturing carbon can stop climate change“
„David Keith, a professor of public policy and applied physics at Harvard University, isn’t counting on dire[nbsp]reports to change that. Instead, he is seriously exploring the possibility of altering[nbsp]the climate system itself to counteract the escalating dangers,[nbsp]using technology to create our own knob on[nbsp]the Earth’s[nbsp]thermostat.“
