Wind turbines are killing bats, including ones on the endangered
species list, at nearly double the rate set as acceptable by the
Ontario government, the latest monitoring report indicates.

Watching for flash drought
Could the Imminent U.S. Heat Wave Trigger a Flash Drought?

Excerpts
"It wasn't too long ago--in 2012--that a promising-looking spring
morphed into a terrible summer for the U.S. Midwest. A long-term
drought that began in late 2010 had intensified over the Southern
Plains in 2011, punishing farmers and ranchers and facilitating the
loss of roughly 10% of all trees in Texas.
"The real shocker was how quickly drought conditions took hold
further north across the Midwest in the summer of 2012, leading to
the most widespread U.S. drought conditions since the 1930s."
"While long-term drought can emerge simply through a lack of
precipitation, a flash drought is closely linked to hot summer
weather."
"At first, the landscape may not be particularly dry, in which case
large amounts of water vapor flow from vegetation and soils into the
scorching surface air (as is expected later this week). If the heat
is strong and sustained enough, the landscape quickly dries out and a
flash drought takes hold."
