The TROPICS research cruise from Tenerife to Trinidad: Tracing oceanic processes using corals and sediments

 By Torben Struve, Research Postgraduate, Department of Earth Science & Engineering  and Grantham Institute for Climate Change

How to start a retrospective on two amazing months at sea? Probably at the beginning! In the beginning there was…an idea! The idea was to reconstruct abrupt changes in chemistry and ocean circulation in the Equatorial Atlantic Ocean to learn about global climate and deep-water habitats. The plan was to do so by collecting sediments, seawater and deep sea corals and analysing all of these for their geochemical composition.

Developing this idea into our actual scientific cruise, JC094, took several years of planning and preparation, led by principal investigator and chief scientist Dr.

Temperature and rainfall extremes in a warming world

By Dr Flora MacTavish

Governments, planning authorities, companies and individuals all need information about  the impact of climate change on extreme weather in the future. A recent paper [1] investigates changes in extremes both globally and locally.

We can be relatively certain of the signature of climate change on a global or continental scale. On the other hand, estimating changes on a country-wide scale is harder and estimating them on a local scale (i.e. to the nearest few kilometres) is very difficult.

In the new study, scientists calculated the proportion of global land area in which certain weather extremes are expected to increase.
