Climate Change: Wildlife & the Environment
‘A single piece of plastic’ can kill sea turtles, says study BBC September 13, 2018
Researchers found there was a one in five chance of death for a turtle who consumed just one item – rising to 50% for 14 pieces. The team found that younger turtles are at a higher risk of dying from exposure to plastic than adults. The authors say their research raises concerns over the long term survival of some turtle species.
What the world needs now to fight climate change: More swamps The Conversation September 12, 2018
…the world needs more swamps – and bogs, fens, marshes and other types of wetlands. These are some of the most diverse and productive ecosystems on Earth. They also are underrated but irreplaceable tools for slowing the pace of climate change and protecting our communities from storms and flooding. Scientists widely recognize that wetlands are extremely efficient at pulling carbon dioxide out of the atmosphere and converting it into living plants and carbon-rich soil. As part of a transdisciplinary team of nine wetland and climate scientists, we published a paper earlier this year that documents the multiple climate benefits provided by all types of wetlands, and their need for protection. … Vast stores of carbon have accumulated in wetlands, in some cases over thousands of years. This has reduced atmospheric levels of carbon dioxide and methane – two key greenhouse gases that are changing Earth’s climate. … Natural wetlands typically absorb more carbon than they release. But as the climate warms wetland soils, microbial metabolism increases, releasing additional greenhouse gases. In addition, draining or disturbing wetlands can release soil carbon very rapidly.
