    Much of the carbon in rivers originates from wildfires and is ultimately buried in the oceanic carbon sink, suggest measurements from 18 rivers globally. Rivers transport almost a gigaton of carbon to the oceans every year.

    Enhanced upwelling and CO2 degassing from the subpolar North Pacific during a warm event 14,000 years ago may have helped keep atmospheric CO2 levels high enough to propel the Earth out of the last ice age.
