The CENOGRID shows Earth has experienced four distinct climate states over the last 66 million years. The detailed climatic changes of the past can be studied like a colorful barcode and provide context for ongoing anthropogenic change and how exceptional it is. Earth’s climate has gradually cooled for the last […]

Animation Earth’s oceans help to slow global warming by absorbing carbon from our atmosphere – but fully observing this crucial process in the upper ocean and lower atmosphere is difficult, as measurements are taken not where it occurs, the sea surface, but several meters below. New research uses data from […]

Nova Southeastern University researchers lead team studying smooth hammerhead sharks. They are some of the most iconic and unique-looking creatures in our oceans. While some may think they look a bit “odd,” one thing researchers agree on is that little is known about hammerhead sharks. Many of the 10 hammerhead […]

Sea ice can act as an agent of climate change on a variety of timescales and spatial scales—it’s not just a passive responder to change. The Little Ice Age may have arisen “out of the blue,” from internal variability within the climate system, rather than in response to an external […]

For that reason, monitoring […]
