Ozone levels in Tucson and other Arizona urban areas are increasing as temperatures hit record or near-record levels every year with growing scientific consensus that continued increasing temperatures will make future ozone levels, and, in effect, health risks worse.
This warming trend, combined with pollution from cars, power plants and chemical plants, is expected to increase the number of days each year that New Jersey residents inhale unsafe levels of ozone pollution.
Local temperature data from 1970 to 2018 shows warming trends across the country — and Americans are already feeling the effects.
Delaware's future could be shaped by climate action.
Rising temperatures are simultaneously escalating hazards posed by droughts, heat waves, storms and heavy rainfall in the River City, even as they push up sea levels, worsening flood risks.
Recent research shows that unchecked warming pollution could bring concurrent climate crises to U.S. cities by midcentury — and that emissions cuts could reduce the danger.
Most U.S. cities have experienced an increase in the average number of mosquito disease danger days each year. El Paso's increase was larger than most, raising risks of West Nile infections.
Climate change is causing a change in location of disease-carrying mosquitoes as the world warms, likely leading to a significant public health challenge in the U.S.
