This is not the first disease bats have given us. Rabies possibly originated in bats. So did, and does, Ebola, outbreaks of which usually trace back to people coming into contact with bat roosts in caves, trees or buildings.

Climate change has done more good than harm so far and is likely to continue doing so for most of this century. This is not some barmy, right-wing fantasy; it is the consensus of expert opinion. Yet almost nobody seems to know this.
A "rational optimist" like me thinks the world will go on getting better for most people at a record rate, not because I have a temperamental or ideological bent to good cheer but because of the data. Poverty, hunger, population growth rates, inequality, and mortality from violence, disease and weather - all continue to plummet on a global scale. But a global optimist can still be a regional pessimist. When asked what I am pessimistic about, I usually reply: bureaucracy and superstition.
Which would you rather have in the view from your house? A thing about the size of a domestic garage, or eight towers twice the height of Nelson’s column with blades noisily thrumming the air. The energy they can produce over ten years is similar: eight wind turbines of 2.5-megawatts (working at roughly 25% capacity) roughly equal the output of an average Pennsylvania shale gas well (converted to electricity at 50% efficiency) in its first ten years.
