  • Geoengineering: Worthy of Cautious Evaluation?

    If the increasing concentrations of greenhouse gases due to human activities are indeed causing inadvertent change in the climate, then can we not counter these influences by advertent changes of some type, deliberately geoengineering the climate to ensure optimal conditions? This is a question that was first considered several decades ago, soon after acceptance of indications that it was indeed ...

  • The Geoengineering Dilemma: To Speak or not to Speak

    An intriguing dichotomy has developed within the field of atmospheric and climate research. On the one side, it has become common practice to examine pessimistic future scenarios of anthropogenic pollutant emissions and their environmental impacts.  Not surprisingly, compared to the alternative “best guess” or “maximum feasible reduction” emissions scenarios, the pessimistic scenario ...

  • Geoengineering: Encouraging Research and Overseeing Implementation

    Ideas on how to engineer Earth’s climate, or to modify the environment on large scales to counter human impacts, do not enjoy broad support from scientists. Refereed publications that deal with such ideas are not numerous nor are they cited widely. Paul Crutzen (2006) analyzes the idea of intentionally injecting sulfur into the stratosphere, to enhance the albedo of Earth, so as to slow the ...

  • Why geoengineering can be only part of the climate solution

    Climate change is not a technological problem, so a technological fix is not enough. The failure of the Kyoto Protocol and the underlying process of the United Nations Framework Convention on Climate Change (UNFCCC) has led to substantial interest in geoengineering technologies, under the usual (and not entirely irrational) view that if policy can’t work, perhaps technology ...

  • Study finds geoengineering research ‘free for all’

    The ‘plan B’ of using geoengineering to rescue humanity from the impact of climate change exists in a ‘vacuum’ of international regulations, according to a recent review. Proposals to counteract the effects of global warming by engineering the ...

  • Geoengineering climate Change: Treating the symptom over the cause?

    The present article by Crutzen (2006) on the use of albedo enhancement to address the problem of greenhouse warming is bound to evoke diverse reactions among the community. It is important to note that Crutzen argues that this idea be studied in depth and openly before any large scale action is taken. A basic assumption to this approach is that we, humans, understand the Earth system sufficiently ...

  • Snoqualmie falls riverbank stabilization case study

    Puget Sound Energy - Snoqualmie Falls Redevelopment Project In 2009, PugetSound Energy began a comprehensive upgrade of the hydroelectric infrastructure at Snoqualmie Falls - a power generation facility built in 1890. Loose soils and heavy rainfall contributed to a landslide along the Snoqualmie River bank in the Fall of 2010, and GeoEngineers was commissioned to provide a long-term design ...

  • The aerosol–cloud–climate conundrum

    The complexity of the atmospheric aerosol and its connection with clouds and climate are illustrated with a host of examples against the background of our present limited state of understanding. A discussion of related feedbacks demonstrates the difficulties of resolving all respective research issues. The key role of aerosols and clouds in anthropogenic climate change make the high uncertainties ...

  • Controlling the Earth's albedo using reflective hollow glass spheres

    Volcanic eruptions have been found to cool the Earth's atmosphere by ejecting dust into the atmosphere. It should be possible to mimic this effect by designing a substitute for this dust consisting of buoyant reflective glass bubbles. This substitute will form a more efficient and long lasting sunscreen. This paper describes the design of such glass bubbles, and the implications and constraints ...

  • Climate Strategy with Co2 Capture from the Air

    Abstract It is physically possible to capture CO2 directly from the air and immobilize it in geological structures. Air capture differs from conventional mitigation in three key aspects. First, it removes emissions from any part of the economy with equal ease or difficulty, so its cost provides an absolute cap on the cost of mitigation. Second, it permits reduction in concentrations faster ...

  • City Of Redmond – Wellhead Protection Program, EQuIS Implementation

    Project Overview The City of Redmond (City) has several water quality related programs (e.g., Groundwater Monitoring, Drinking Water, Surface Water) responsible for contributing to the protection and management of ground and surface water resources. These water quality programs (Programs) have either regulatory responsibility authorized by state or county oversight agencies or, have local ...

  • Science and development highlights of 2012

    The year was marked by one of the most anticipated global environmental meetings in 20 years: the UN Conference on Sustainable Development (Rio+20), held in Rio de Janeiro, Brazil. The summit was a ...

  • Marine Snow Storms: Assessing the environmental risks of ocean fertilization

    The threats posed by climate change to the global environment have fostered heightened scientific and commercial interest in marine geo-engineering schemes designed to boost the capacity of the oceans to absorb atmospheric carbon dioxide. This is the primary goal of a process known as ocean fertilization, which seeks to increase the production of organic material in the surface ocean in order to ...

  • Geo-engineering, the Law of the Sea, and Climate Change

    Plans to address climate change increasingly include proposals for geo-engineering projects, whose effects are likely to be global, at best only partly predictable, not necessarily wholly benign, and extend beyond their objective. Geo-engineering proposals should receive detailed, precautionary scrutiny by the international community, which requires sophisticated international legal instruments ...

    How will science and technology fare at the Rio+20 summit? Aisling Irwin looks at scientists' demands and assesses their chances. Is this the last chance for scientists to save the planet? The UN Conference on Sustainable Development — Rio+20 — enters its final phase of negotiations next week at a summit to be attended by more than 130 heads of state. At stake ...

  • Geo-Engineering to Confine Climate Change: Is it at all Feasible?

    Paul Crutzen (2006) has suggested a research initiative to consider whether itwould be feasible to artificially enhance the albedo of the planet Earth to counteract greenhouse warming. The enhancement of albedo would be achieved by intentionally injecting sulfur into the stratosphere. The rational for proposing the experiment is the observed cooling of the atmosphere following the recent major ...

  • How does climate stack up against other worst-case scenarios?

    Climate isn’t the only catastrophe threatening the planet, but it may be the one most in need of attention and resources. The following is excerpted from Climate Shock (2015) by Gernot Wagner and Martin L. Weitzman. Published here with permission from Princeton ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...
