Alaska Dispatch News: Alaska scientist suggests storing carbon dioxide in polar ice to blunt warming

„In December, the University of Alaska Fairbanks geologist-volcanologist will tack a poster in a San Francisco meeting hall amid the crashing surf of a thousand conversations. To educated passersby at the fall meeting of the American Geophysical Union, he will explain his idea of capturing a greenhouse gas and raining it out over the coldest place on Earth.“

Higgins, P.A.T. (2014): Climate Change Risk Management. American Meteorological Society (AMS). Washington, D.C. (AMS Policy Program Study.

Climate change risk management approaches generally fall into four broad categories: 1) mitigation—efforts to reduce greenhouse gas emissions; 2) adaptation—increasing society’s capacity to cope with changes in climate; 3) geoengineering or climate engineering—additional, deliberate manipulation of the earth system that is intended to counteract at least some of the impacts of greenhouse gas emissions; and 4) knowledge-base expansion—efforts to learn and understand more about the climate system, which can help support proactive risk management.

Doda, Baran (2014): Why is geoengineering so tempting?

Doda, Baran (2014): Why is geoengineering so tempting? Centre for Climate Change Economics and Policy (Working Paper, 192).

„This paper studies the potential benefits from geoengineering in a standard one-sector growth model augmented with a carbon cycle and a climate system. These benefits can be interpreted as a lower bound for the direct and indirect costs which would make geoengineering less preferable to abatement.“

„If the goal of climate policy is to minimize climate risks, this concern should not be grounds for restricting or prohibiting climate engineering research. Three potential means for this concern to manifest in genuinely deleterious ways, as well as policy options to reduce these effects, are identified.“

„In this paper, we will review and assess technical and theoretical aspects of land-based, atmosphere-based, ocean-based and space-based geoengineering schemes as well as their potential impacts on global climate and ecosystem.“
