IT’S GETTING HOT IN HEREįor many across the globe, recent months brought the summer from hell. But the time has come for governments and the private sector to address them and to more seriously commit to applying geoengineering techniques while greatly increasing research to monitor the risks they pose.
This potential consequence, in particular, explains the strong opposition to geoengineering from climate change activists and governments intent on addressing climate change by reducing fossil fuel emissions.įor decades, such concerns could remain merely theoretical. There are also concerns about the moral hazard created by encouraging continued or even greater use of carbon dioxide–emitting fossil fuels by suggesting the harm they do can be avoided. But human intervention in the earth’s natural systems raises questions about the potentially dangerous impacts it could have on the weather and the oceans. Scientists are confident that geoengineering would have the desired effect because periodic volcanic eruptions, which spew all kinds of particles into the air, have cooled the earth in the past. Now, however, as the pace and destructiveness of extreme weather events seem to be quickening beyond even some of the most pessimistic forecasts, geoengineering might finally have its moment. But it has never attracted as much official attention or private investment as other methods of preventing climate change, mitigating its worst effects, or adapting to it. Over the years, interest in geoengineering has periodically surged. “The possibilities of deliberately bringing about countervailing climatic changes therefore need to be thoroughly explored”. “The climatic changes that may be produced by the increased content could be deleterious from the point of view of human beings”, they noted. President Lyndon Johnson suggested that some kind of tinkering with the planet’s mechanics might be necessary. In 1965, a group of scientific advisers to U.S.
Although the idea sounds futuristic, the basic concept has been around for a long time. “Geoengineering” can mean a number of things, but it usually refers to the attempt to offset the rising global temperatures that result from the greenhouse effect by introducing particles in a systematic and sustained way into the earth’s atmosphere so that it better reflects the sun’s rays.
