What is lake-effect snow? Hint: it involves a lake (TIME): A timely look at the science behind lake-effect snow. Brr!

For the monarch butterfly, a long road back (The New York Times): Researchers at the University of Georgia are studying the human effects on migratory behavior of monarch butterflies. The recent efforts of amateur conservationists to replenish declines in milkweed may be part of the problem – in many cases, the milkweed available for planting is an exotic species that may lead to unseasonal breeding.

Long-eared bat listing gets pushback (Great Lakes Echo): Timber industry advocates and bat conservationists are at odds over the federal protection of the northern long-eared bat. Fish and Wildlife Service officials recommended the listing and have distributed guidelines on how to best log forests without harming bats. These recommendations suggest restricted logging from April through October, which led to pushback from the forest industry.

State of the Climate: Global average temperature is highest on record for October (NOAA): The combined average temperature over global land and ocean surfaces for October 2014 was the highest on record for October at 0.74 degrees Celsius above the 20th century average of 14.0 degrees Celsius.
