Fridays for future

KÆLTIA’s Team in its aim to contribute with the global awareness of the Climate Change, summarise below some critical news:

  • Scientists say that global warming makes the kind of extreme rainfall that caused deadly flash flooding in western Europe last month more likely, though it remains unclear exactly how much.
  • Rain fell at the highest point on Greenland’s ice sheet—possibly for the first time—in an event Danish scientists on Monday said was most likely driven by climate change. According to a European study published in January, the melting of the Greenland ice sheet is expected to contribute to the overall rise in sea levels by 10 to 18 centimetres by 2100, 60 percent faster than the previous estimate.
  • A global inventory has revealed that CO2 emissions from oil refineries were 1.3 Gigatonnes (Gt) in 2018 and could be as large as 16.5 Gt from 2020 to 2030. Based on the results, the researchers recommend distinct mitigation strategies for refineries in different regions and age groups. The findings appear August 20 in the journal One Earth.
  • The presence of mercury in the world’s oceans has ramifications for human health and wildlife, especially in coastal areas where the majority of fishing takes place. But while models evaluating sources of mercury in the oceans have focused on mercury deposited directly from the atmosphere, a new study led by Peter Raymond, professor of ecosystem ecology at the Yale School of the Environment and published in Nature Geoscience shows that rivers are actually the main source of the toxic heavy metal along the world’s coasts.
  • Tens of thousands of hydraulic fracturing wells drilled over the past few years from Pennsylvania to Texas to North Dakota have made unconventional oil and gas production part of everyday life for many Americans. This raises questions about the impacts to local communities and human health. While some studies document that hydraulic fracturing can contaminate groundwater, new evidence shows the practice can also reduce surface water quality.
  • Ice losses from Thwaites Glacier in West Antarctica are currently responsible for roughly 4 percent of the global sea-level rise. This figure could increase, since virtually no other ice stream in the Antarctic is changing as dramatically as the massive Thwaites Glacier.
  • There is abundant evidence that changes in the climate, both increased temperature and reduced precipitation, are making wildfires worse in the western U.S. The relationship between climate and wildfire seems obvious and universal: hotter + drier = more and worse wildfire.
