Whether looking forward to ice fishing season, crossing fingers for a rare journey to Lake Superior's sea caves on the shores of Bayfield County or just enduring the long cold months of winter, chances are the dates that lakes freeze and thaw are one mark by which one can measure the season in Wisconsin.

Wisconsin's climate is gradually warming and is forecast to get warmer by the mid-21st century. Climatologists track this regional reflection of a planetary trend in large part through a series of satellites that gather data about Earth's lands, seas and air, and subsequently, use this information to help model long-term climate projections.

As a highly contagious avian influenza virus spread through the U.S.'s poultry population in 2015, something else began catching on: the word "depopulation."

The avian influenza epidemic of 2015 required a cooperative effort between state and federal agricultural officials and the poultry industry. Wisconsin's Department of Agriculture, Trade and Consumer Protection worked with affected farms to confirm the presence of H5N2 and drew on its own expertise and personnel, as well as those of federal agencies and ag-industry partners to coordinate a response.
