Society needs to decide whether geoengineering, failing attempts to curb emissions, should be researched as plan b. Are the dangers associated with geoengineering too great? Should we purely be focusing on the challenge of mitigating carbon emissions?
What is geoengineering?
Geoengineering refers to the deliberate manipulation of the earth’s climate.
Is geoengineering detracting from the real issue?
There is a risk that serious consideration of geoengineering could give the impression that the need to reduce carbon emissions is not as important and that global warming has a possible technical solution. If serious consideration is given to researching geo-engineering projects, the pressure might be taken off governments to tackle the source of climate change and continue the decarbonisation of society.

Professor David Keith University of Calgary, Canada
Environmental scientist Prof David Keith works at the intersection of climate science, way-new energy, and public power. His research has taken him into some far-out realms of geoengineering — dramatic, cheap, sometimes shocking solutions to a warming atmosphere, such as blowing a Mt. Pinatubo-size cloud of sulfur into the sky to bring the global temperature down.
Soil is our vital resource yet we tend to overlook it. Most people have contact with soil daily, even if only walking over it, but will rarely consider its value.
