Heat waves can be deadly, especially when they combine high temperatures with elevated humidity levels that make the air feel even hotter. The impacts can be especially strong in cities, which often are several degrees warmer than nearby rural areas due to the urban heat island effect. These three articles from The Conversation’s archives describe steps that communities can take to adapt as climate change makes heat waves more frequent and intense.
Accurate weather forecasts save lives. NASA's Atmospheric Infrared Sounder (AIRS) instrument, launched on this date 15 years ago on NASA’s Aqua satellite, significantly increased weather forecasting accuracy within a couple of years by providing extraordinary three-dimensional maps of clouds, air temperature and water vapor throughout the atmosphere's weather-making layer. Fifteen years later, AIRS continues to be a valuable asset for forecasters worldwide, sending 7 billion observations streaming into forecasting centers every day.
The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface between the land and the atmosphere, that tiny amount plays a crucial role in everything from agriculture to weather and climate, and even the spread of disease.
