MIT Technology Review: Rules for Geoengineering the Planet
By Janos Pasztor „We have to at least consider geoengineering. And that’s where the problems start.“

„We conducted an online survey on the general public’s perception and acceptance of SRM in Canada, China, Germany, Switzerland, the UK, and the USA. Our findings confirmed the need for an international perspective, as we found several cross-country differences. Chinese respondents, for example, indicated greater acceptance for SRM than their North American and European counterparts.“

„We find that, barring unforeseen and transformative technological advancement, anthropogenic emissions need to peak within the next 10 years, to maintain realistic pathways to meeting the COP21 emissions and warming targets. Fossil fuel consumption will probably need to be reduced below a quarter of primary energy supply by 2100 and the allowable consumption rate drops even further if negative emissions technologies remain technologically or economically unfeasible at the global scale.“

Climate Central: A Cooler Future May Hinge on Removing CO2 From the Air
„Climate pollution equal to about 27 times humans’ 2015 carbon dioxide emissions may have to be removed from the atmosphere and locked underground forever in order to keep the globe from warming beyond 1.5°C (2.7°F) above preindustrial levels, according to a new study. The research, led by scientists at the International Institute for Applied Systems Analysis, or IIASA, in Austria, adds to the mounting evidence that countries will have to physically remove carbon dioxide from the atmosphere to prevent global warming from exceeding dangerous levels.“
Carbon Brief: UK launches ‘world first’ research programme into negative emissions
„The UK has launched a £8.6m national research programme on how to remove greenhouse gases from the atmosphere. It is thought to be the world’s first research programme dedicated to this topic.“
The Conversation: Worthless mining waste could suck CO₂ out of the atmosphere and reverse emissions
„The Paris Agreement commits nations to limiting global warming to less than 2˚C by the end of the century. However, it is becoming increasingly apparent that, to meet such a massive challenge, societies will need to do more than simply reduce and limit carbon emissions. It seems likely that large scale removal of greenhouse gases from the atmosphere may be called for: so-called “negative emissions”.“
Nonprofit Chronicles: It’s crunch time for climate philanthropy. What should foundations do?
„Geoengineering: Efforts to mitigate carbon emissions will likely fall short. So we should be aggressively researching geoengineering–deliberate, large-scale efforts to counter the effects of global warming. It sounds scary, to be sure. So does chemotherapy, until cancer strikes.“
Project: NERC with £8.6 million UK research programme on greenhouse gas removal
„To help answer these questions, the £8·6[nbsp]million Greenhouse Gas Removal Research Programme will evaluate the potential and wider implications of a variety of options. For example, researchers will investigate the potential for increasing carbon storage in agricultural soil and forests, and new ways to remove methane gas from the air on a local scale. Other researchers will look into using waste materials from mining as a greenhouse gas removal technique, and explore how bioenergy crops could be used in power stations in combination with carbon capture and storage methods. Recognising that the UK alone cannot solve these problems, the research will address the political, socio-economic, technological and environmental issues concerning the potential for greenhouse gas removal on a global scale.“
