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.
- A comprehensive assessment of 12 different strategies for reducing beef production emissions worldwide found that industry can reduce greenhouse gas (GHG) emissions by as much as 50% in certain regions, with the most potential in the United States and Brazil. The study, “Reducing Climate Impacts of Beef Production: A synthesis of life cycle assessments across management systems and global regions,” is published April 5 in Global Change Biology
- New paper published in American Geophysical Union Journal of Geophysical Research Biogeosciences shows benefits of Louisiana coastal restoration to soil carbon sequestration. Protection and restoration of these marshes is vital to help protect the pool of buried carbon in the soils, and to prevent release of carbon to the atmosphere from soil oxidation
- Microplastics have reached the farthest corners of the Earth, including remote fjords and even the Mariana Trench, one of the deepest parts of the ocean. Recently, yet another distant area of our planet has been found to contain these pollutants: glaciers and ice sheets. An Eos article published in March examines how microplastics create changes in these icy ecosystems, and underscores the importance of properly distinguishing them from another form of pollution in snow, black carbon.
- The University of Maryland (UMD) has collaborated with Cornell University and Stanford University to quantify the man-made effects of climate change on global agricultural productivity growth for the first time. In a new study published in Nature Climate Change, researchers developed a robust model of weather effects on productivity, looking at productivity in both the presence and absence of climate change. Results indicate a 21% reduction in global agricultural productivity since 1961, which according to researchers is equivalent to completely losing the last 7 years of productivity growth. This work suggests that global agriculture is becoming more and more vulnerable to ongoing climate change effects, with warmer regions like Africa, Latin America, and the Caribbean being hit the hardest.
