Watch the new video released by Scripps Oceanography Scripps scientists measured a record level of carbon dioxide in the atmosphere: 415 parts per million, on Sunday, May 12, 2019. This daily record, the Keeling Curve, is considered the foundation of modern climate change research. Geochemist Charles David Keeling joined Scripps

Carbon dioxide from Silicon Valley affects the chemistry of Monterey Bay
This map shows how carbon dioxide from land flows out across Monterey Bay with morning land breezes. Base image: Google Earth MBARI researchers recently measured high concentrations of carbon dioxide in air blowing out to sea from cities and agricultural areas, including Silicon Valley. In a new paper in PLOS
Tipping points of gastric pH regulation and energetics in the sea urchin larva exposed to CO2 induced seawater acidification
Highlights We determined the sensitivity thresholds for survival development and growth in sea urchin larvae exposed to acidified conditions. Determination of physiological parameters including midgut pH homeostasis, metabolic rates and expression of midgut acid-base transporters demonstrates a physiological tipping point at pH 7.2. This work demonstrates substantial resilience of an important
Impacts of urban carbon dioxide emissions on sea-air flux and ocean acidification in nearshore waters
Devon Northcott, Jeff Sevadjian, Diego A. Sancho-Gallegos, Chris Wahl, Jules Friederich, Francisco P. Chavez Abstract Greatly enhanced atmospheric carbon dioxide (CO2) levels relative to well-mixed marine air are observed during periods of offshore winds at coastal sensor platforms in Monterey Bay, California, USA. The highest concentrations originate from urban and
