Projected anthropogenic warming and increases in CO2 concentration present a twofold threat, both from climate changes and from CO2 directly through increasing the acidity of the oceans. Future climate change may be reduced through mitigation (reductions in greenhouse gas emissions) or through geoengineering. Most geoengineering approaches, however, do not address the problem of increasing ocean acidity. A combined mitigation/geoengineering strategy could remove this deficiency. Here we…

Geoengineering - a part of climate change policies

International efforts on abating climate change, focusing on reductions of greenhouse gas emissions, have thus far proved unsuccessful. This naturally motivates exploration of other strategies. We…

Implications of delayed actions in addressing carbon dioxide emission reduction in the context of geo-engineering

Carbon dioxide emissions need to be reduced well below current emissions if atmospheric concentrations are to be stabilised at a level likely to avoid dangerous climate change. We investigate how…

Ecosystem Impacts of Geoengineering: A Review for Developing a Science Plan

Current research suggests that SRM or CDR might diminish the impacts of climate change on ecosystems by reducing changes in temperature and precipitation, however, sudden cessation of SRM would exacerbate the climate effects on ecosystems, and someCDR might interfere with oceanic and terrestrial ecosystem processes.

Climate impacts of geoengineering in a delayed mitigation scenario

Decarbonization in the immediate future is required to limit global mean temperature (GMT) increase to 2°C relative to preindustrial conditions, if geoengineering is not considered. Here we use the…

Problems with geoengineering schemes to combat climate change

The proposed geoengineering schemes, results from climate models and why geoengineering is not the best option to deal with climate change are reviewed.

The Science of Geoengineering

Carbon dioxide emissions from the burning of coal, oil, and gas are increasing atmospheric carbon dioxide concentrations. These increased concentrations cause additional energy to be retained in…

Nitrogen and Geoengineering

Proposals for the deliberate manipulation of Earth’s climate to tackle human-induced global warming — popularly named ‘geoengineering’ — have grown in number as fast as the frustration over…

Climate engineering to mitigate the projected 21st-century terrestrial drying of the Americas: Carbon Capture vs. Sulfur Injection?

Abstract. To mitigate the projected global warming in the 21st century, it is well recognized that society needs to cut CO2 emission and other short-lived warming agents aggressively. However, to…

Climate engineering to mitigate the projected 21st-century terrestrial drying of the Americas: a direct comparison of carbon capture and sulfur injection

<p>To mitigate the projected global warming in the 21st century, it is well-recognized that society needs to cut CO2 emissions and other short-lived warming agents aggressively. However, to stabilize…

Efficacy of geoengineering to limit 21st century sea-level rise

The least risky and most desirable way of limiting sea-level rise is bioenergy with carbon sequestration, however aerosol injection or a space mirror system reducing insolation at an accelerating rate of 1 W m-2 per decade from now to 2100 could limit or reduce sea levels.

Interpretation of High Projections for Global-Mean Warming

This work interprets the new warming range in probabilistic terms, accounting for uncertainties in emissions, the climate sensitivity, the carbon cycle, ocean mixing, and aerosol forcing, and shows that the probabilities of warming values at both the high and low ends of the TAR range are very low.
