Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years, University of Otago researchers believe chlorofluorocarbons(CFCs) aren’t the only things to blame. In a study, just published in Nature Communications, the group analysed the monthly and daily ozone changes, at different altitudes and latitudes within the Antarctic … Read more
The extent to which aerosol particles affect the climate depends on how much water the particles can hold in the atmosphere. The capacity to hold water is referred to as hygroscopicity (K) and, in turn, depends on further factors — particularly the size and chemical composition of the particles, which can be extremely variable and … Read more
Carbon dioxide removal (CDR) technologies that could be critical tools to combat climate change have developed in line with other technologies from the last century. However, according to new studies led by Gregory Nemet, a professor at the University of Wisconsin-Madison, these technologies need to develop faster to meet policy targets aimed at limiting global … Read more
Forest modeling by Oregon State University scientists shows that a site’s productivity — an indicator of how fast trees grow and how much biomass they accumulate — is the main factor that determines which time period between timber harvests allows for maximum above-ground carbon sequestration. The findings, published in the journal Forests, are important for … Read more
