To counteract extreme weather and climate change, researchers are looking to geoengineering—large-scale technological and scientific interventions to counteract the damage we’ve caused to the planet.
Mirrors in space, capturing carbon dioxide, seeding clouds with particles, and injecting gasses into the atmosphere are all examples of geoengineering. We’re at the earliest stages of research and exploration, but it’s a controversial solution to our climate change problem. When Congress approved the $1.4 trillion spending package in December 2019, it included a small amount of money to further this research: $4 million in the National Oceanic and Atmospheric Administration budget and $15 million in the Department of Energy coffers.
Scientists can run simulations using available data, but it’s impossible to predict the second- and third-order implications of geoengineering in advance. Even so, the fate of the whole planet is at stake. The scientific community is divided on geoengineering because some of the proposed techniques could potentially adversely affect natural weather patterns. No one country can—or should—take a unilateral lead on geoengineering. The National Academy of Sciences is studying whether solar geoengineering research should be pursued, and if so, under what parameters.
Proposals for geoengineering projects are starting to gain wider public acceptance, which could influence regulators to allow experimentation in the years to come.
