Keystone XL pipeline gets Nebraska’s approval, clearing a key hurdle in 9-year effort and allowing Trump to claim a win

TransCanada’s $8 billion Keystone XL pipeline got the go-ahead from the Nebraska Public Service Commission on Monday, clearing the last regulatory hurdle in a nine-year effort to build a line needed the carry thick crude oil from Alberta’s tar sands region to refineries on the Texas gulf coast. But the five-member commission rejected TransCanada’s preferred…

Increased rainfall volume from future convective storms in the US

Increased rainfall volume from future convective storms in the US Increased rainfall volume from future convective storms in the US, Published online: 20 November 2017; doi:10.1038/s41558-017-0007-7 Limitations with climate models have previously prevented accurate diagnosis of future changes in mesoscale convective systems (MCSs). A convection-permitting model now indicates that summer MCSs will triple by 2100…

Near doubling of storm rainfall

Near doubling of storm rainfall Near doubling of storm rainfall, Published online: 20 November 2017; doi:10.1038/s41558-017-0017-5 Large, intense thunderstorms frequently cause flooding and fatalities. Now, research finds that these storms may see a threefold increase in frequency and produce significantly heavier downpours in the future, far exceeding previous estimates. from Nature Climate Change – AOP…
