Canada announced on Monday it will virtually eliminate the use of traditional coal-fired electricity by 2030, a stance contrasting sharply with that of U.S.

What usually comes to mind when speaking about biodiversity hotspots are tropical regions, pristine areas and magnificent forests.

Most excess deaths that occur during extreme hot weather events do not have natural heat recorded as an underlying or contributing cause. This study aims to identify the specific individuals who died because of hot weather using only secondary data. A novel approach was developed in which the expected number of deaths was repeatedly sampled from all deaths that occurred during a hot weather event, and compared with deaths during a control period. The deaths were compared with respect to five factors known to be associated with hot weather mortality.

A major factor for the population decline of Native Americans after European contact has been attributed to infectious disease susceptibility. To investigate whether a pre-existing genetic component contributed to this phenomenon, here we analyse 50 exomes of a continuous population from the Northwest Coast of North America, dating from before and after European contact.

Extreme large-scale North American cold events are associated with strong undulations in the tropospheric jet stream which bring cold polar air southward over the continent. Here we propose that these jet undulations are associated with the North American part of the Circumglobal Teleconnection Pattern—a pair of zonally oriented waves of zonal wave number 5 which are in zonal quadrature with each other. While the Pacific/North American pattern is associated with the first circumglobal wave pattern, North American extreme cold events are associated with the second pattern.

Worldwide riverine thermal pollution patterns were investigated by combining mean annual heat rejection rates from power plants with once-through cooling systems with the global hydrological-water temperature model variable infiltration capacity (VIC)-RBM. The model simulates both streamflow and water temperature on 0.5° × 0.5° spatial resolution worldwide and by capturing their effect, identifies multiple thermal pollution hotspots.

The 207-to-81 vote in the House of Commons yesterday came 30 days before the pact comes into force globally, and brings the total number of nations that have endorsed it to 74.

UNITED NATIONS: The landmark Paris agreement on climate change will enter into force in 30 days, after the number of countries ratifying the accord surpassed a key threshold on Wednesday.

This report assesses the preparedness of Canada’s provinces and Yukon to limit climate change related flood damage, relative to current (2016) and future (2030) major precipitation events. The report provides direction to the provinces and territory to build upon efforts to limit flood risk.
