One third of the African urban population exposed to extreme heat by 2090

An international team of researchers has combined demographic projections and climate scenarios across Africa for the first time. Rapid urbanization combined with climate change is having a major impact on the living conditions of city-dwellers in Africa, especially in terms of exposure to extreme – or even lethal – temperatures.

Climate change may push Santa Ana fire season into winter months

Climate models predict a narrowing of the Santa Ana season in tandem with the wet season in Southern California over the next century, which could leave vegetation dry and fire-prone as winds peak in December and January, according to a new study.

Who is vulnerable to the impacts of tropical cyclones and why?

Tropical cyclones, and the torrential rains and strong winds these storms bring along with them, threaten coastal communities around the world and are expected to increase in intensity due to climate change. Whether or not a natural hazard, such as a tropical cyclone, becomes a natural disaster depends on whether the hazard overwhelms existing human infrastructure in a particular country or region. But when does a natural disaster result in fatalities?

Pacific Ocean typhoons could be intensifying more than previously projected

Changes to the uppermost layer of Earth’s oceans due to rising temperatures are likely causing an increase in intense Pacific Ocean typhoons, suggesting strong typhoons may occur more frequently than scientists project in the coming decades, according to new research.

Half-degree of warming could have big impact on water availability

Approximately 117 million more people could face water shortages if global temperatures increase 2 degrees Celsius above pre-industrial levels compared to a 1.5-degree Celsius increase in temperatures, a new study suggests. The world’s water cycle, including evaporation and precipitation, is expected to intensify with global warming, according to the study. This could affect the distribution of freshwater and constrain the global water supply, which poses risks to national food security, economic prosperity and societal well-being.

New study predicts warming climate will drive thousands to ER for heat illness

Even under the most charitable climate scenario where emissions are restricted across the globe, ER visits for hyperthermia in the United States could still increase by 21,000 by 2050, costing up to $38 million according to a new study in GeoHealth.

Increasing heat drives off clouds that dampen California wildfires

Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds that shade many southern coastal areas of California, leading to increased risk of wildfires.
