Canada has committed to an electricity system by 2030 that will be 90 per cent carbon non-emitting, a move that requires transitioning to renewable energy such as wind, solar and biomass.

We May Be Past The Peak, But Hurricane Season Is Far From Over
Over the course of a month, we’ve seen tropical cyclone activity in the Atlantic basin heat up quite a bit – most notably with the landfall of Hurricane Florence, which dumped historic amounts of rain on portions of the Carolinas.
Large underwater experiment shows that “turbidity currents” are not just currents, but involve movement of the seafloor itself
Turbidity currents have historically been described as fast-moving currents that sweep down submarine canyons, carrying sand and mud into the deep sea. But a new paper in Nature Communications shows that, rather than just consisting of sediment-laden seawater flowing over the seafloor, turbidity currents also involve large-scale movements of the seafloor itself. This dramatic discovery, the result of an 18-month-long, multi-institutional study of Monterey Canyon, could help ocean engineers avoid damage to pipelines, communications cables, and other seafloor structures.
Scientists seek a deeper understanding of how silver kills bacteria
Silver has been used for centuries as an antimicrobial to kill harmful bacteria. Ancient civilizations applied the metal to open wounds. Ship captains tossed silver coins into storage barrels to keep drinking water fresh.
Larger cities have smaller water footprint than less populated counterparts
Global sustainability is important now more than ever due to increasing urban populations and the resulting stress it can have on natural resources. But increased populations in cities may lead to greater efficiency, as a team of Penn State researchers discovered when they analyzed the water footprint of 65 mid- to large-sized U.S. cities.
USGS Crews Work Fast to Capture Evidence of Devastating Carolina Floods
The floodwaters that covered wide swaths of the Carolinas’ coastal plain are finally receding, more than two weeks after Hurricane Florence made landfall Sept. 14 near Wrightsville Beach, North Carolina, and U.S. Geological Survey hydrographers are moving in rapidly to the areas where the flooding lingered longest.
