Nos émissions de gaz à effet de serre font grimper les températures. Mais un autre phénomène se joue dans notre atmosphère et vient contrecarrer une partie du réchauffement. Jusqu’à quand, encore ?
#ClimateChange exacerbates air pollution by creating conditions that can increase the formation of pollutants like ground-level ozone.
Rising global temperatures, for instance, can lead to more frequent and intense heatwaves, which accelerate the chemical reactions that form smog and other harmful #Aerosols.

China's efforts to reduce air pollution contributed to accelerated warming since 2010.
Restrictions of atmospheric aerosol and precursor emissions in East Asia have contributed to the observed global surface warming acceleration since 2010, according to Earth System Model simulations isolating regional changes.

Penguin Poo Seeds Antarctic Clouds
Forming clouds requires more than just water vapor; every droplet in a cloud forms around a tiny aerosol particle that serves as a seed that vapor can condense onto. Without these aerosols, there are no clouds. In most regions of the world, aerosols are plentiful — produced by vegetation, dust, sea salt, and other sources. But in the Antarctic, aerosol sources are few. But a new study shows that penguins help create aerosols with their feces.
Penguin feces is ammonia-rich, and that ammonia, when combined with sulfur compounds from marine phytoplankton, triggers chemistry that releases new aerosol particles. The researchers measured ammonia carried on the wind from nearby penguin colonies and found that the birds are a large ammonia source, producing 100 to 1000 times the region’s baseline ammonia levels. In combination with another ingredient in penguin guano, the researchers found the penguins boosted aerosol production 10,000-fold. That means penguins can actually influence their environment, helping to create clouds that keep Antarctica cooler. (Image credit: H. Neufeld; research credit: M. Boyer et al.; via Eos)
