What's New Green infrastructure: what is it? (9/8) Green infrastructure — natural and nature-based engineered systems that mimic natural processes — can be used to make communities better prepared and more resilient to extreme weather and coastal hazards that are becoming more frequent with climate change.
COMMENTARY: Breaking the ice Michigan Radio (8/12) The U.S. Coast Guard has eight small ships that can be used as icebreakers in normal times and there’s only one heavy Coast Guard icebreaker that can deal with winters like the last two: the nine-year-old Mackinaw. At least one new heavy icebreaker is needed.
The Genesee, recently raging, is now a trickle Democrat & Chronicle (7/30) It’s feast to famine for the Genesee River, which two weeks ago raged through downtown Rochester, N.Y. and today is barely a trickle.Lack of rain is one reason, and deliberate draining of the section between Court Street and the High Falls is another.
Catfish floundering in yards after heavy rains MLive (6/26) When a deluge of rain led to the overflow of a pond in Allegan County, Michigan, hundreds of large bullheads swam into neighboring yards and found themselves stranded there in receding waters with no way to return to the pond.
"Wait a day and the weather will change" is an apt description of weather in the Great Lakes region, especially in the spring and fall. That's because the region is affected by both warm, humid air from the Gulf of Mexico and cold, dry air from the Arctic. In general, the north experiences cooler weather, while the south has warmer temperatures. The entire basin experiences four distinct seasons.
The Great Lakes also have a big influence on the climate. Acting as a giant heat sink, the lakes moderate the temperatures of the surrounding land, cooling the summers and warming the winters. This results in a milder climate in portions of the basin compared to other locations of similar latitude. The lakes also act as a giant humidifier, increasing the moisture content of the air throughout the year. In the winter, this moisture condenses as snow when it reaches the land, creating heavy snowfall in some areas, known as "snow belts" on the downwind shores of the lakes. The shores of Lake Superior are prone to this "lake effect" snow and have recorded up to 350 inches of snow in a single year. During the winter, the temperature of the lakes continues to drop. Ice frequently covers Lake Erie but seldom fully covers the other lakes.

Historical Conditions GLIN: Compare snow melt (snow water equivalent) for the upper Great Lakes basin: 1997-2000 From the summer of 1997 to today, water levels on the middle Great Lakes have fallen from near record highs to near record lows. This decline is nearly 3.5 feet on lakes Michigan, Huron, St. Clair and Erie. This trend is forecasted to continue for the foreseeable future due in part to the fact that the drainage basins for lakes Superior and northern Michigan and Huron (the headwaters for the Great Lakes) have had one of the driest winters on record. Snowmelt runoff is a key component in replenishing groundwater and tributary stream flows into the Great Lakes.
