Climate Impact of Soot Is Exaggerated, Study Says

The global warming effect of ‘black carbon,’ or soot, has been greatly exaggerated due to mistaken assumptions about the atmospheric altitude at which its particles are concentrated, according to a new study.

Toledo’s Algae Bloom in Line with Climate Projections

A two-day ban on drinking water has been lifted in Toledo, Ohio. But the toxic algae bloom that led to the ban is still floating around Lake Erie and ones like it could become more common as the climate continues to change in a warming world. Nutrients in agricultural runoff is the biggest contributor to algae blooms in Lake Erie. What brings that… Read More
