Megafaunal extinctions driven by too much moisture

by University of Adelaide, April 18, 2017 in ScienceDaily


Studies of bones from Ice Age megafaunal animals across Eurasia and the Americas have revealed that major increases in environmental moisture occurred just before many species suddenly became extinct around 11-15,000 years ago. The persistent moisture resulting from melting permafrost and glaciers caused widespread glacial-age grasslands to be rapidly replaced by peatlands and bogs, fragmenting populations of large herbivore grazers.

The idea of moisture-driven extinctions is really exciting because it can also explain why Africa is so different, with a much lower rate of megafaunal extinctions and many species surviving to this day, says Professor Cooper.

China Gas Output Rises to Record as Coal Production Rebounds

by Bloomberg News, April 17, 2017


China’s natural gas production surged to a record last month and coal output rebounded as economic growth accelerated power use in the world’s largest energy user.

Natural gas production in March rose 8.2 percent from the average of the first two months of the year to a record 13.6 billion cubic meters, according to data Monday from the National Bureau of Statistics. Coal output rose almost 13 percent over the same period to average 9.67 million tons a day, the highest daily level since December, according to Bloomberg calculations based on the data.
