Yet caving in to this opposition would raise, rather than reduce, the dangers to the planet. Geoengineering is not an alternative to mitigating climate change by cutting carbon emissions, but it may be needed as a complement to it. Although pressure for cuts in carbon emissions through negotiati...
Afforestation can be a pretty effective geoengineering technique to fight climate change, when undertaken on a large scale. Trees make use of solar energy to absorb CO2 from the atmosphere and water from the ground. They breathe out the oxygen and use the leftover carbon to grow their roots a...
Particularly, geoengineering holds out the possibility of a less costly short-term response to climate change than rapid de-carbonisation of stationary energy and transport systems. However, there are many considerable risks associated with geoengineering, including damage to environmental and social ...
Geoengineering aims to mitigate man-made climate change by making large-scale modifications to the Earth’s surface or atmosphere. One of the main proposals discussed by scientists is stratospheric albedo modification: changing the reflective power of the atmosphere 10–50 km above the Earth’s surfa...
Climate change poses many risks to society and natural ecosystems, and action will be required to reduce its harms1. While the most straightforward and certain way to reduce these harms is by reducing, and eventually reversing, emissions of greenhouse gases, such mitigation is expensive and subject...
Damages due to climate change are expected to increase with global warming, which could be limited directly by solar geoengineering. Here we analyse the views of 723 negotiators and scientists who are involved in international climate policy-making and w
Overall, this work demonstrates that aerosols have the potential to cool the climate but slowing down the global warming would require large scale actions aimed at climate cooling. However, these actions include many uncertainties and risks which will need to be studied in detail. This requires sim...
Shuckburgh at Cambridge says greenhouse gas emissions clearly need to fall rapidly and substantially. “Given that, it is absolutely beholden on us to investigate all approaches for that, but [be] fully cognisant of the risks of any active intervention in the climate.” ...
Recent reporting by theLos Angeles Timesand others revealed, however, that Exxon’s rhetoric ran counter to its owninternal conclusionsabout the risks of climate change, as the company reengineered oil platforms and pipelines to account for the rising sea levels that both top executives and the ...
geoengineering offsets all future warming. While this reduces overall climate change substantially, we show that in these simulations, it goes too far in some respects leading to about 9% of the land area experiencing greater climate change, i.e. seeing the effects of climate change exacerbated....
