Prior to the industrial revolution CO2 was absorbed from the air by land plants, exported via rivers to the ocean and released back into the air creating a balanced cycle on time scales of centuries to millennia. Today, humans are altering this balance by releasing fossil carbon (e.g. coal, oil, natural gas). About one third of fossil CO2 is absorbed by the ocean, changing the ocean from a net source to the air, to a net sink.
Recent results published by the Global Carbon Project (GCP) earlier this month in Earth System Science Data show that global carbon emissions from burning fossil fuels did not grow in 2015 and are projected to rise only slightly in 2016, marking three years of almost no growth. The plateau in global emissions is largely the result of reduced coal use in China. However, emissions grew by 5.2% in 2015 in India, the world’s second most populous developing country, and other developing countries... more

Changes in large-scale ocean circulation due to climate change appear to be underway throughout the world ocean and stand to significantly affect marine ecosystems and resources. This new study by McClatchie et al. investigated whether changes in the character of coastal waters over the last 30 years have affected the composition of fish communities in the southern California Current ecosystem. The... more
