In recent years, the presence of red tide algae in the Mexican Pacific Ocean has occurred from Manzanillo Bay, Colima, all along the western Mexican coast to the Bay of Mazatlan, Nayarit, and as far north as Ensenada, La Paz, Baja California. Fortunately, although Jaltemba Bay did have some of the toxic algae, the civic leaders and government were immediately in action.
Sitting at a mile above sea level and in the shadow of the Rocky Mountains, Denver is known for having an extreme climate. But the most recent temperature swing ranked as one of the biggest ever observed.
An Okanagan program was designed 15 years ago to control the invasive species of starlings
Special report: A huge disruption to California's coastal ecosystem is under way after several years of unusually warm ocean conditions and drought.
Decades ago, wall lizards from the Mediterranean got a toehold near Victoria. Now they’re island-hopping.
Pueblo broke a 102-year-old daily record for snowfall Monday with 3.8 inches — and the cold weather continued Tuesday. Monday’s snowfall broke the old record of 2.9 inches set in 1917.
The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations, we project that extremes of wet-bulb temperature in South Asia are likely to approach and, in a few locations, exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.
