KÆLTIA’s Team in its aim to contribute with the global awareness of the Climate Change, summarise below some critical news:
- Methane, the main component of natural gas, is the cleanest-burning of all the fossil fuels, but when emitted into the atmosphere it is a much more potent greenhouse gas than carbon dioxide. By some estimates, seafloor methane contained in frozen formations along the continental margins may equal or exceed the total amount of coal, oil, and gas in all other reservoirs worldwide. Yet, the way methane escapes from these deep formations is poorly understood.
- Plastics in the ocean can release chemicals that cause deformities in sea urchin larvae, new research led by the University of Exeter shows, where the urchins developed a variety of abnormalities, including deformed skeletons and nervous systems.
- Mangroves and seagrasses grow in many places along the coasts of the world, and these ‚blue forests‘ constitute an important environment for a large number of animals. However, the plant-covered coastal zones do not only attract animals but also microplastics, a new study from the University of Southern Denmark shows. Those animals can ingest microplastics and that this may affect their organism, they may suffocate, die of starvation, or the small plastic particles can get stuck different places in the body and do damage.
- Over the coming decades, our economy and society will need to dramatically reduce greenhouse gas emissions as called for in the Paris Agreement. But even a future low-carbon economy will emit some greenhouse gases, such as in the manufacture of cement, steel, in livestock and crop farming, and in the chemical and pharmaceutical industries. To meet climate targets, these emissions need to be offset. Doing so requires „negative emissions“ technologies, by means of which CO2 is removed from the atmosphere and permanently stored in underground repositories.
- In a recent article in Sustainability, scientists from Reykjavik University (RU), the University of Gothenburg and the Icelandic Meteorological Office describe finding microplastic in a remote and pristine area of Vatnajokull glacier in Iceland, Europe’s largest ice cap. Microplastics may affect the melting and rheological behaviour of glaciers, thus influencing the future meltwater contribution to the oceans and rising sea levels.
