In a 6-3 ruling, the Supreme Court held that an Obama administration plan to regulate carbon emissions from power plants exceeded the power that Congress gave to the Environmental Protection Agency.
Thanks to their high concentrations of phytoplankton, African lakes emit less CO2 than their boreal counterparts, with important consequences for climate modelling.
