A recent review has unveiled an innovative method for monitoring fossil fuel CO₂ emissions using satellite observations of co-emitted NO₂. This approach promises to provide more precise and efficient emission tracking compared to traditional ground-based methods, overcoming significant challenges in distinguishing human-made emissions from natural sources. By capitalizing on the short atmospheric lifespan and high detectability of NO₂, this method enhances the ability to monitor emissions at a variety of scales, from individual power plants to entire nations. This new technique plays a vital role in bolstering global climate change mitigation efforts and ensuring countries meet their commitments under the Paris Agreement.

The SXSW Conference will take place from March 7-15 in Austin, Texas, bringing together a vibrant mix of ideas and innovations. Once again, UC San Diego will take center stage, showcasing cutting-edge research, transformative discussions on critical global challenges and a film premiere.
