In a courtesy call to HE the President of Malta at San Anton Palace on Thursday, February 11, 2021, Dr Noel Aquilina from the Department of Chemistry, accompanied by Professor Emmanuel Sinagra, Head of the Department of Chemistry and Dean of the Faculty of Science at the University of Malta, presented the findings of a landmark study.
A new study reports that worldwide emissions of a potent substance alleged to deplete the Earth’s ozone layer, which is the protective barrier that absorbs the harmful UV rays from the Sun—have decreased very fast and are now again on the decline.
On February 19, the world's second-largest greenhouse gas emitter, the United-States, will rejoin the Paris Agreement. This will kickstart a year of intensifying policy activity ahead of the United Nations Climate Change conference (COP26) in November, when countries will re-commit to their emissions reduction goals.
( Institute for Advanced Sustainability Studies e.V. (IASS) ) Millions of tonnes of plastic waste find their way into the ocean every year. A team of researchers from the Institute for Advanced Sustainability Studies (IASS) in Potsdam has investigated the role of regional ocean governance in the fight against marine plastic pollution, highlighting why regional marine governance should be further strengthened as negotiations for a new global agreement continue.
A potent ozone-depleting chemical whose emissions unexpectedly spiked in recent years has quickly dropped back to much lower levels, putting the recovery of the stratospheric ozone layer back on track, according to a new study by scientists at MIT, the University of Bristol, and other institutions in South Korea, the U.S., Japan, Australia, and Switzerland.
Dramatic decreases in traffic caused by COVID-19 shutdowns improved air quality in car-dependent states but didn't offset additional forms of pollution in other parts of the country.
Often, when populations and economies boom, so does air pollution--a product of increased fossil-fuel consumption by vehicles, industry and households.
On a brisk November morning in 2018, a fire sparked in a remote stretch of canyon in Butte County, California, a region nestled against the western slopes of the Sierra Nevada mountains. Fueled by a sea of tinder created by drought, and propelled by powerful gusts, the flames grew and traveled rapidly. In less than 24 hours, the fire had swept through the town of Paradise and other communities, leaving a charred ruin in its wake.
Researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warn of the impact the current tourism model in the Mediterranean islands has on the production of marine litter on beaches, and recommend taking advantage of the situation generated by the Covid19 pandemic to rethink a new more sustainable model.
The outbreak of COVID-19 raised a question about the relationship between anthropogenic emissions and air pollution, which has aroused heated discussion. Research on air-quality changes caused by the lockdowns in different areas shows similar substantial reductions in primary emissions. However, regional disparities exist in responses of secondary pollutants to emissions reduction, especially fine particulate matter and ozone (O3).
