  • The extent to which the location of the Intertropical Convergence Zone (ITCZ)—a primary influence over tropical hydrology—varied in the past remains uncertain. Here, the authors use a transect of marine sediment cores to quantify latitudinal migrations of the ITCZ during the penultimate deglaciation.

  • During glacial periods the oceans stored carbon removed from the atmosphere, yet identifying precisely where that storage occurred remains challenging. Here, the authors show that the deep equatorial Pacific Ocean was a reservoir for respired carbon during glacial periods for at least the last 350 kyr.

  • A combination of palaeoclimate proxies and simulations shows that a common mechanism controls El Niño variation in cold and warm states, which supports expectations of more extreme El Niño occurrence in the future.

  • There has been active debate over microbial life in Antarctic subglacial lakes owing to a paucity of direct observations from beneath the ice sheet and concerns about contamination in the samples that do exist; here the authors present the first geomicrobiological description of pristine water and surficial sediments from Subglacial Lake Whillans, and show that the lake water contains a diverse microbial community, many members of which are closely related to chemolithoautotrophic bacteria and archaea.
