Sentences with phrase «by albedo modification»
«There is a potential risk that if you cool the planet by albedo modification, it could provide less incentive to reduce reliance on fossil fuels,» says Marcia McNutt, a geophysicist, current editor - in - chief of Science and chair of a committee that evaluated climate intervention techniques for the U.S. National Academy of Sciences.

Critics argue that albedo modification and other «geoengineering» schemes are risky and would discourage nations from trying to reduce their emissions of carbon dioxide, the heat - trapping gas that comes from the burning of fossil fuels and that is causing global warming by absorbing increasing amounts of energy from sunlight.
Albedo modification would work by lacing the atmosphere with tiny particles or aerosols that would reflect sunlight and mimic natural processes.
Albedo modification might also work by using aerosols to seed cloud formation in a lower atmospheric layer called the troposphere.
So the real choice is between exploring albedo modification openly or in relative secrecy, he says: «I believe in sunshine and democracy, and I really think this should be done by the U.S. government and in a transparent way.»
That's the only kind of albedo - modification geoengineering I could countenance, and by the time that is needed, presumably we'll have the wisdom to deploy it safely and the technology to make it robust.
In contrast, even the best albedo modification strategies are currently limited by unfamiliar and unquantifiable risks and governance issues rather than direct costs.
The deployment of CDR techniques is limited by their cost, not by their riskiness or likely effectiveness (as is the case for Albedo Modification approaches).
Regarding the other half of the warming, what fraction of that is due to regional to super regional scale surface / near surface waste heat, albedo / vegetation modification, and, disturbances to boundary layer laminar flows by human made structures and tree plantings?
In contrast, the purpose of albedo modification technologies is to introduce a new form of human influence on the climate system by altering the amount of sunlight absorbed by the Earth.
Solar Radiation Management (SRM) or «albedo modification» is a class of technologies that could lower global average temperatures and offset some of the worst impacts of climate change by reflecting a portion of incoming solar radiation back into space before that radiation could be trapped by greenhouse gases in the atmosphere.

While the second option, also called albedo modification, is relatively inexpensive and could quickly lower the planet's temperature, it could have unwanted effects on the Earth's weather pattern, which could potentially bring drought to some regions or be used as a weapon by governments or certain individuals.
