Summary

Few records of past climate exist from the tropics, hampering the understanding of global climate patterns on time scales of thousands of years. In his Perspective, Baker contrasts the hydrological patterns observed in tropical South America during northern high latitude cold events with those observed in a record from Lake Malawi, East Africa, reported by Johnson et al. The study indicates that the flux of methane into the atmosphere is largely controlled by Africa.
