Gideon Henderson has developed new techniques for determining the timescales, magnitude and effects of past global climate change. His work led to the rejection of many proposed mechanisms of glacial-interglacial CO2 cycles and to the realisation that these are driven by processes in the southern ocean. With new approaches to dating sediments he showed that certain glacial cycles are inconsistent with models of orbital forcing and was able to quantify weathering fluxes. He bridged the gap between modellers and geochemists in developing ocean circulation calculations that mimic proxy data and leading a new international initiative to understand ocean compositions.
