The carbon capture company Climeworks only captures a fraction of the CO2 it promises its machines can capture. The company is failing to carbon offset the emissions resulting from its operations – which have grown rapidly in recent years.
A UN meeting this week considered a motion on a suite of technologies known as ‘solar radiation modification’, but no consensus could be reached on the controversial topic.
During the past decades, the idea of acting to counteract the damage done to the ecosystem by humankind's activities has moved along at least two planning stages.
Techniques such as solar radiation management may have unintended consequences, scientists say
This Research Plan was prepared in response to a requirement in the joint explanatory statement accompanying Division B of the Consolidated Appropriations Act, 2022, directing the Office of Science and Technology Policy (OSTP), with support from the National Oceanic and Atmospheric Administration (NOAA), to provide a research plan for “solar and other rapid climate interventions.”
The federal effort could set the stage for more studies into the feasibility, benefits and risks of one of the more controversial means of combating climate change.
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated.
