Kleidon, Axel; et al. (2014): The hydrological sensitivity to global warming and solar geoengineering derived from thermodynamic constraints

Kleidon, Axel; Kravitz, Ben; Renner, Maik (2014): The hydrological sensitivity to global warming and solar geoengineering derived from thermodynamic constraints. In Geophys. Res. Lett., pp. n/a. DOI 10.1002/2014GL062589.

„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.“

Asayama, S. (2014): Catastrophism toward opening up or closing down? Going beyond the apocalyptic future and geoengineering

Asayama, S. (2014): Catastrophism toward ‚opening up‘ or ‚closing down‘? Going beyond the apocalyptic future and geoengineering. In Current Sociology 63 (1), pp. 89–93. DOI 10.1177/0011392114559849.

„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.“

The Engergy Collective: Are Negative Emissions a „Myth?“

„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.“

re/code: Harvard’s David Keith Knows How to Dial Down the Earth’s Thermostat. Is It Time to Try?

„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.“
