The 2019 ozone hole reached its peak extent of 6.3 million square miles (16. 4 million square kilometers) on September 8. Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion this year.

Between 2005 and 2016, the shift away from coal saved an estimated 26,610 lives and 570 million bushels of crops. The decommissioning of coal-fired power plants in the continental United States has reduced nearby pollution and its negative impacts on human health and crop yields, according to a new University […]

North American surface temperatures for Dec. 26, 2017-Jan. 2, 2018: even if it is extremely cold in a region, this does not mean that climate change has stopped.

Ultra-low emissions control equipment in China. Polluting emissions from Chinese thermal power plants declined significantly between 2014 and 2017, according to research involving the University College London. The reductions are important in helping to control China’s national emissions which could lead to an improvement in air quality and considerable health benefits. A […]

James McSpiritt, an optomechanical engineer in Princeton University’s Department of Civil and Environmental Engineering, adjusts an eddy covariance tower, a stationary device used to measure air pollution. The device allowed the researchers to collect data about methane emissions that they could compare to samples collected from the mobile laboratory. Credit: […]
