The pandemic has tugged carbon emissions down, temporarily. But levels of the powerful heat-trapping gas methane continue to climb, dragging the world further away from a path that skirts the worst effects of global warming.
Stanford scientists find the growth of phytoplankton in the Arctic Ocean has increased 57 percent over just two decades, enhancing its ability to soak up carbon dioxide. While once linked to melting sea ice, the increase is now propelled by rising concentrations of tiny algae.
The study of sub-Saharan Africa finds that a relatively small increase in airborne particles significantly increases infant mortality rates. A cost-effective solution may lie in an exotic-sounding proposal.
The first-of-its-kind study reveals that subsidies for the planting of commercially valuable tree plantations in Chile resulted in the loss of biologically valuable natural forests and little, if any, additional carbon sequestration.
Global carbon dioxide emissions are down dramatically in the wake of COVID-19. A new study pinpoints where energy demand has dropped the most, estimates the impact on annual emissions and points the way to a less polluted future.
COVID-19 and other looming threats could make it much harder for people to access food. David Lobell, director of Stanford’s Center on Food Security and the Environment, outlines likely scenarios and possible solutions.
