BBC: Drinking water could be contaminated with methane gas and chemicals due to fracking, water companies have warned. Water UK, which represents all major UK water suppliers, said the shale gas extraction method posed a threat if not "carefully planned and carried out". It also warned fracking's "huge" use of water could cause shortages in areas of low supply, like South East England.

LA Times: Early morning is a frenetic time at a wildfire command post. Biologists, meteorologists, foresters and firefighters hustle into tents and grab laptops to review overnight reports, prepping for the day's assault. Fire behavior analysts run computer models that spit out information crucial to putting out the blaze: how many acres a fire will probably burn, in which direction and with what intensity. In recent years, the models have been rendered practically obsolete, unable to project how erratic...
