    A study of atmospheric transport shows that, at certain times of the year, a large part of the air arriving in Asia has passed over Europe, perhaps carrying pollution from one continent to the other. Analyses of atmospheric composition will be needed to confirm or disprove the possibility.

    At the Palaeocene/Eocene boundary, 55 million years ago, temperatures and atmospheric concentrations of CO2were especially high. New data, which track the response of the oceans' biosphere, point to a plausible mechanism by which such an episode of greenhouse warming may end.
