Geoengineering refers to deliberately manipulating the Earth's natural systems, such as the atmosphere or oceans, in order to counteract or slow down the effects of climate change. It involves techniques like reflecting sunlight away from the Earth's surface or removing carbon dioxide from the atmosphere. The goal is to artificially intervene and lessen the impacts of global warming caused by human activities.
Full definition
A survey
of geoengineering research in a piece by Michael Specter in The New Yorker last year introduced the chemotherapy analogy to me.
These scenarios can then be fed into models to quantify potential outcomes of
solar geoengineering for people and the environment.
Panel Urges More Research
on Geoengineering as a Tool Against Climate Change — New York Times.
But that depends on how we control carbon emissions from this point onwards, and whether or not we engage
in geoengineering projects.
Otto then takes us through the failure of cap - and - trade as an originally Republican idea that is now ridiculed as experimenting with the economy, and the rise of proposals
for geoengineering solutions such as sulfur aerosol injections — an idea that «is easily the riskiest suggestion in the history of human civilization,» which resembles «taking up a crack habit.»
And second, this framing elevates the idea of solar
geoengineering as a viable climate change abatement strategy vastly above the current scientific consensus on this topic, painting carbon removal solutions in a much more radical light than do most climate experts.
In his article on
geoengineering solutions to climate change, Clive Hamilton criticises our promotion of «market - driven solutions» (17 July, p...
They argue that any future solar
geoengineering projects need to be geared toward reducing the risk of such a catastrophe as much as possible.
The extremely varied temperature extremes are indicative of the «weather whiplash» effect being created by global
geoengineering programs.
Yet opposition to the techno - fix is also more entrenched in the United States, and would likely be rallied to defeat the Prometheans if
geoengineering proposals became serious, leaving China the most likely power to assume the role of global climate regulator.
It is yet another warning that the mainstream media's exuberance about climate
geoengineering options as a silver bullet may be belied by evidence on the ground.
Larger - scale climate response tests or deployment of
geoengineering at material scales are likely to cause a risk of significant harm to the environment or human safety.
Embarking on a planetary - scale
aerosol geoengineering project would produce «a wide range of unintended regional consequences,» Samset says.
Nicholson says that even if research agencies under Trump avoid research
into geoengineering techniques such as albedo modification, the U.S. intelligence community might remain interested, especially in whether other countries are pursuing their own planetary cooling technologies, which could affect many nations.
The researchers made it clear in Tuesday's press conference that they do not advocate
using geoengineering as an excuse for humanity to continue recklessly emitting carbon dioxide and other greenhouse gases.»
The innovative research centres on the impact solar
geoengineering methods that inject aerosols into the atmosphere may have on the frequency of tropical cyclones.
The list of environmentally devastating factors directly relating to the
ongoing geoengineering programs is very long.
Alarmed by the lack of progress by governments in finding ways to slow emissions of CO2, climate researchers have begun to examine so -
called geoengineering schemes (ScienceNOW, 9 November 2007).
Twin ensembles will be investigated for responses to IPCC A1B emissions scenario between 2000 and 2080, both with and
without geoengineering activities starting in 2005.
To build the capacity for an informed global dialogue on
geoengineering governance, a critical mass of well - informed individuals throughout the world must be developed, and they must talk to each other, as well as to their own networks.
A conference in the UK this week is discussing the pros and cons of
such geoengineering methods.
Sorry to double post, but putting sulfate particles into the air to dim the sun is a strawman argument
against geoengineering since using engineered particles instead would be much less expensive and could be designed to avoid damaging the ozone layer:
It is generally placed under the rubric of climate
geoengineering strategies termed «carbon dioxide removal» options, in contrast to strategies that seek to reduce incoming solar radiation to reduce total radiative forcing.
The people who don't
like geoengineering will suggest the IPCC is a method for normalising it.»
Greenhouse gas reductions remain the priority The termination effect is one example of
how geoengineering experiments can differ.
Research to date has not determined that there are large -
scale geoengineering approaches for which the benefits would substantially outweigh the detriments.
In an essay published in the May / June 2014 issues of The Bulletin of The Atomic Scientists, we built on this theme to argue that the conversation on
geoengineering needs to more broadly account for the ways religion can and should be included.
The most likely situations in
which geoengineering technologies will actually be implemented at - scale are those that occur in a high climate sensitivity world (i.e. if the climate's response to greenhouse gas forcings leads to a larger response than science's present best - guess).
