\"So we can expect to see the opposite effect in the deep tropics -- a decrease in tropical cyclones close to the equator. Radiocarbon dating helped researchers work out the timing of ancient storms in the region, revealing an uptick in cyclone frequency during the Little Ice Age. By analyzing tree rings, coral cores and fossilized marine organisms, scientists were able to reconstruct ancient changes in climate conditions. RELATED More frequent tropical storms mean less recovery time for coastlines\"It turns out the past provides some useful analogies for the climate change that we're currently undergoing. Now we're trying to go back and determine the drivers of tropical cyclones,\" said Donnelly, a WHOI senior scientist.
