Unseasonably Warm Weather in Wisconsin

Below is the Wisconsin Department of Natural Resources’ (DNR) Outdoor Report summary for March 10, 2016. However, conspicuous by absence is any mention that Wisconsin’s unusually warm weather this month is at all related to human activities that cause climate change. Some of the many sources of fossil and other fuel combustion that emit greenhouse gases to the atmosphere in Wisconsin include: fossil fuel burning in highway motor vehicles (gasoline and diesel oil); jet aircraft (refined oil/jet fuel); electric power producing plants (primarily coal, and natural gas – methane); natural gas burning for heating homes, buildings, churches and other buildings, recreational utility vehicles; road construction vehicles; in cement and asphalt manufacturing; in snowmobiles, boats, motor vehicles used in tractors and other agricultural machinery, in lawn mowing, in logging, and in other miscellaneous motorized products that burn fuel. Other greenhouse gas emissions may come from mining operations including sand and gravel mining and mining for metals, and from animal livestock propagation for food sales.

Despite the findings and recommendations from the United Nations’ Intergovernmental Panel on Climate Change (IPCC), which concludes the climate change problem is “urgent”, as does President Obama, Wisconsin’s Republican Governor Scott Walker and the state’s Republican lawmakers have refused to even hold a citizen hearing regarding the growing threat of climate change, not just to Wisconsin’s future economy, but also the quality of life future residents and visitor to Wisconsin will be provided, as well as the threats of a changing climate to animal and plant life in Wisconsin for generations to come.
Unseasonably warm weather melts snow cover, slows maple tapping efforts

Wisconsin has experienced some unseasonably warm weather in the last week with daytime temperatures in the 50s and 60s and even a low 70 reported in Milwaukee. The warm weather has melted most of the snow cover statewide, with just snow surviving in some forested areas of the Northwoods. Snowmobile and cross-country ski trails are now closed statewide and most will remain so even if the state does experience a late season snowfall.

State park and forest trails that were groomed for skiing are now open again to hiking, but most properties are reporting that rail-trail, mountain bike and horse trails are closed, as conditions are soft and muddy and use of trails in these conditions can cause significant damage to trail surfaces.

With the general inland game fish season now closed except on those waters open to game fishing year-round, only a few panfish anglers have been venturing out, but ice conditions are rapidly deteriorating and many shorelines in southern and central Wisconsin are opening up, making access difficult and dangerous.

Most anglers on Green Bay are removing fishing shelters prior to this Sunday’s deadline as waters are rapidly opening up. Anglers were out in high numbers around Sturgeon Bay last weekend with many limits for whitefish reported. Anglers were open water fishing the Fox River at Voyageur Park for walleye but success rates have been low, though with the warmer weather that is expect this to change.

Raccoon, skunk, muskrat, mink, and opossum activity has increased as temperatures have increased and snow has departed. Wild turkeys have been strutting and starting their spring courtship. Flocks are breaking up and the large groups of toms and jakes have already decreased in size as they establish their spring pecking order.

With the warm weather and south winds there has been a significant increase in spring migrants sighted this week, including red-winged blackbirds, killdeer, robins, song sparrows, swamp sparrows, bluebirds, turkey vultures and more. Other early migrants returning to breeding territories include American woodcock, great blue herons and eastern meadowlarks. There was a heavy waterfowl migration across the southern half of the state, including common goldeneyes, all three mergansers, green-winged teal, pintail, wood ducks, and many others. Greater white-fronted geese are moving through in numbers, as are large flocks of Canada geese and occasional cackling, snow, and Ross’s geese. Canada geese are staking out territory and will begin nesting soon. Sandhill cranes are courting and dancing. Bald eagles are incubating eggs and some great horned owls already have chicks.

Maple syrup season has gotten off to a very slow start due to mild temperatures, especially overnight lows staying above freezing. One producer placed out 670 taps late last week and harvested 370 gallons of sap on Monday. The 10-day forecast does not show any significant changes to overnight lows. The concern is that trees will bud out soon resulting in an early end of the season.

A number of observers reported seeing leopard frogs, spring peepers have been heard in the south and salamanders were active with the warm temperatures. Unfortunately the warm weather has also brought out reports from shed hunters and maple tappers finding the first ticks crawling around on them.
