Climate change and bark beetles equal billions of dead trees
Recently, one of my colleagues sent me a story that sums up the media's apathetic appetite for covering the environment.

A more wide-ranging article than I expected:
"Climate change dropped further from the world headlines in 2011 compared to the previous year, even though a vicious one-in-100-year drought in Texas has entered its second year; 70 percent of Mexico is enveloped by its worst drought in 70 years; Australia faced epic flooding costing taxpayers in excess of $5 billion in infrastructure costs; and plants are so confused in their biorhythmic cycles that the white petals of snow drops, normally a spring flower, are now unfurling in the National Arboretum in Washington, D.C."
On bark beetles, any visit to the intermountain high country of the Northwestern US or Southwestern Canada is guaranteed to appall. Previously limited to thin-barked, high-altitude pines such as P. albicaulis, P. flexilis and P. contorta, the beetles are now killing even low-altitude conifers of thick-barked species such as P. ponderosa. The death zone is spreading both upslope and downslope, as well as north and south. Each summer, forest fires are growing in number and intensity.
