Could geoengineering be the solution to climate change? Are the risks worth the potential benefits?<\/p>\n\n\n\n

The field of geoengineering is getting a second look from some scientists, policymakers, and tech billionaires, who wonder whether it could help fend off climate disaster<\/a>. Geoengineering for climate change involves manipulating the Earth\u2019s climate system to counteract the impacts of greenhouse gas emissions.<\/p>\n\n\n\n

Below, we\u2019ll discuss what geoengineering is, why scientists have pushed back against it, and why some are now giving it a cautious second look.<\/p>\n\n\n\n\n\n\n\n

Geoengineering<\/strong> Could Save the World\u2014but at What Cost?<\/h2>\n\n\n\n

Copernicus, the European Union\u2019s Climate Change Service, reports a warmer year-to-date global average temperature<\/a> as of July 2024, and the numbers are unlikely to drop. In August, Australia recorded its hottest winter ever<\/a>, with some areas charting temperatures that were 15 degrees Celsius (59 degrees Fahrenheit) above the norm; the western US also experienced a record-breaking heat wave in October<\/a>. These are some of the latest grim reminders of a climate emergency\u2014a crisis that\u2019s making experts take a second look at a contentious strategy to help avert a disaster: geoengineering.<\/p>\n\n\n\n

What Is Geoengineering?<\/strong><\/h3>\n\n\n\n

Geoengineering for climate change is manipulating the Earth\u2019s climate system to counteract the impacts of greenhouse gas emissions<\/strong>. Also known as climate engineering, it can be divided into two strategies<\/a>: solar radiation management<\/em> and carbon dioxide removal<\/em>.<\/p>\n\n\n\n

AI’s Growing Carbon Footprint<\/a> <\/strong>

Tech workers, researchers, and environmentalists warn that without a rapid, radical shift in AI system development that accounts for its environmental impact, the technology\u2019s energy consumption <\/strong>will surpass that of the entire global workforce by 2025<\/strong><\/a>.<\/strong> At present:\u00a0

Training a single AI model can produce emissions equal to <\/strong>more than 626,000 pounds of carbon dioxide<\/strong><\/a>\u2014roughly five times the emissions generated by the average American car during its lifetime.
A single data center can use the same amount of electricity as <\/strong>50,000 homes<\/strong><\/a>\u2014and by 2030, data centers are anticipated to double their electricity use<\/a>.\u00a0The cloud\u2019s carbon footprint now <\/strong>surpasses that of the entire airline industry<\/strong><\/a>, <\/strong>generating roughly 2% of global emissions.

As AI\u2019s popularity and energy demands grow, <\/strong>so will its carbon footprint<\/strong><\/a>\u2014potentially <\/strong>imperiling global climate goals<\/strong><\/a>.<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

1. Carbon Dioxide Removal (CDR)<\/h4>\n\n\n\n

This strategy focuses on removing CO2 from the atmosphere to directly reduce greenhouse gas concentrations that are leading to climate change. Examples of CDR are:<\/p>\n\n\n\n
