Conducted by an international research team, including the University of South Australia, the research is the first to examine what happens when cyclones and fires interact. The study found that when severe weather events occur in close succession (more common due to climate change) they can have major impacts on the environment, with the interactive …
Fibrous polyesters, primarily from textiles, were found in all samples. The majority of microplastic fibres identified were found in the Antarctic air samples, revealing that Antarctic animals and seabirds could be breathing them. ‘The issue of microplastic fibres is also an airborne problem reaching even the last remaining pristine environments on our planet’, stated co-author …
The research is published online today in the journal Science. The research follows government and industry investment to create infrastructure and markets for carbon-free liquid ammonia fuel that will not contribute to greenhouse warming. Liquid ammonia is easy to transport and packs a lot of energy, with one nitrogen and three hydrogen atoms per molecule. …
Dust from the dry Puna Plateau in northwestern Argentina was an important source of iron for the nutrient-deficient South Pacific in the last two glacial cycles — especially at the beginning of these cycles. This was the key finding of a study presented in science journal PNAS by a team of researchers led by geochemist …

According to the UN’s Intergovernmental Panel on Climate Change (IPCC), warming over land areas occurs significantly faster than over oceans, with 1.6 degrees and 0.9 degrees on average, respectively. It means that the global greenhouse gas emissions budget to stay under a 1.5-degree warming on land has already been used up. Now, the new study …
Large parts of Europe are warming twice as fast as the planet on average Read More »
One of the planet’s five great oceanic gyres, humanmade marine debris becomes trapped in a circular ocean current that stretches from the east coasts of North America to the west coasts of Europe and Africa. A new study, published in Marine Pollution Bulletin, has found it contains higher levels of polyethylene, polypropylene, acrylic, and polyamide, …

But this valuable freshwater resource is in danger of disappearing. The planet is now around 1.1 degrees Celsius (1.9 degrees Fahrenheit) warmer than pre-industrial levels, and mountain snowpacks are shrinking. Last year, a study co-led by Alan Rhoades and Erica Siirila-Woodburn, research scientists in the Earth and Environmental Sciences Area of Lawrence Berkeley National Laboratory …

This is the conclusion of a study that for the first time estimates the cost of a green transition not in dollars, but in greenhouse gases. The study appears this week in the Proceedings of the National Academy of Sciences. “The message is that it is going to take energy to rebuild the global energy …
Building green energy facilities may produce substantial carbon emissions, says study Read More »
Changes in the earth’s surface occur as a result of tectonic forces accumulating in the crust, a process called crustal deformation. When forces that are exerted on the crust (stress) from the movement of tectonic plates exceed the strength of the rock, they can change its shape. Measuring these changes (geodetic measurements) can reveal the …

Nuclear energy is a key component of decarbonizing our economy, but large nuclear reactors are often complicated and expensive to build. To make nuclear energy more available and attractive, developers have put forward multiple designs of small modular reactors (SMRs) that have greater flexibility and offer lower up-front costs. Different types of SMRs with advanced …
