Heat stress escalates in cities under global warming
Heatwaves are intensifying in cities due to the double whammy of the urban heat island effect and global warming, according to a new study.
The study’s authors used computer models to simulate with unprecedented detail the temperature changes through the mid-21st century in Belgian cities. They found that heatwaves become hotter, longer and more frequent because of greenhouse gas emissions, and that temperature above the heat stress alarm level increases by a factor of between 1.4 and 15 by the middle of this century.
“The trends are very harmful to an increasing share of people living in the cities, since hot temperatures lead to excessive mortalities, hospital admissions, energy usage and economic loss, which are exacerbated by the urban heat island,” said Hendrik Wouters, of Belgium’s Katholieke Universiteit Leuven and Ghent University.
More deaths from future heat waves could make heat waves the most deadly type of natural disaster in the near future, he added…More

Featured Special Collection
The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer. This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census. The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years. The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades. The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
