Abstract
To understand the effect of chlorophyll solar absorption on coastal upwelling regions, Siyu Meng and colleagues use a coupled ocean–biogeochemistry model and find that chlorophyll absorption causes colder, stronger upwelling in the Pacific Ocean, but warmer, weaker upwelling in the Atlantic Ocean. The authors attribute this to phytoplankton spatial differences, with the Pacific Ocean having more surface chlorophyll, thus the water is warmed at the surface after being upwelled, while subsurface chlorophyll in the Atlantic Ocean causes warming deeper, with these waters then upwelled to the surface. These results highlight the importance of including biological processes into models to better understand ocean thermal structure and dynamics, as broader climate interactions.

期刊介绍：
Nature Climate Change is dedicated to addressing the scientific challenge of understanding Earth's changing climate and its societal implications. As a monthly journal, it publishes significant and cutting-edge research on the nature, causes, and impacts of global climate change, as well as its implications for the economy, policy, and the world at large.
The journal publishes original research spanning the natural and social sciences, synthesizing interdisciplinary research to provide a comprehensive understanding of climate change. It upholds the high standards set by all Nature-branded journals, ensuring top-tier original research through a fair and rigorous review process, broad readership access, high standards of copy editing and production, rapid publication, and independence from academic societies and other vested interests.
Nature Climate Change serves as a platform for discussion among experts, publishing opinion, analysis, and review articles. It also features Research Highlights to highlight important developments in the field and original reporting from renowned science journalists in the form of feature articles.
Topics covered in the journal include adaptation, atmospheric science, ecology, economics, energy, impacts and vulnerability, mitigation, oceanography, policy, sociology, and sustainability, among others.
