Arctic tundra now emits planet-warming pollution, federal report finds
Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution.
Striving for a sustainable Lifestyle
As the world struggles to renounce its burning of fossil fuels, scientists are studying whether atmospheric geoengineering could help limit warming and avert climate catastrophe.
Controversial technologies intended to offset the effects of atmospheric carbon should banned until properly assessed, a group of politicians and scientists have warned, even as they urged developed nations to lead in cutting CO2 emissions.
Geoengineering is often presented as a last-resort technological fix to the climate crisis that can still swoop in and save the day.
But new models suggest that such risky measures, like dimming the Sun, are not enough to save Antarctica now.
Technologies like geoengineering may tackle global warming – but first we need to ditch fossil fuels for renewable energy
