According to a new study by UCLA climate scientists, human-caused climate change is on track to make the Arctic Ocean functionally ice-free for part of each year starting sometime between 2044 and 2067 (by University of California, via Earth news)
The European Union’s investment arm said it will stop funding fossil fuel projects from 2022 as part of a new strategy aimed at fighting climate change (via Earth news)
Residues from billions of doses of antibiotics, painkillers and antidepressants pose a significant risk to freshwater ecosystems and the global food chain. When animals and humans ingest medicines, up to 90 percent of active ingredients are excreted back into the environment (via Earth news)
Climate researchers predict that global temperatures will increase by as much as 2 degrees C by 2050 due to growing concentrations of greenhouse gas emissions in the planet’s atmosphere. For some urban areas, a warming climate is only half the threat. A new study from the Yale School of Forestry & Environmental Studies (F&ES) projects that the growth of urban areas in the coming decades will trigger « extra » warming due to a phenomenon known as the urban heat island effect (UHI) (by Yale University, via Earth news)
Environmental groups Seas At Risk and Transport and Environment have announced the results of a study they commissioned to Reynolds Environmental Sustainability Consultants (RESC). The researchers describe their findings—namely that their evidence that implementing speed limits on ships around the world would reduce the industry’s carbon footprint, and would also reduce air pollution. They noted that reducing speeds would also lower deaths of whales due to collisions with ships (via Earth news).
Hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels, and in many cases this is true. However, a new study reveals that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. The researchers report their results in ACS’ journal Environmental Science & Technology (by American Chemical Society, via Earth news)
