For a warming planet, we're doing nothing in Grand Rapids this summer to erase the negative average temperature anomaly . . . but there's always August if you are a grower, or hope if you're a warmist.
The total temperature anomaly for 2014 in GR was 30.3 degrees F below normal, a little over 2.5 degrees on average per month.
The significance of that may be lost on you, but here in Michigan a couple of degrees makes all the difference between being Michigan and being Wisconsin. On the other side of Lake Michigan at this latitude, average temperature is historically two degrees colder than here on average. There they are exposed to the cold drying winds which come off the plains in winter. Here we have the warming effect of Lake Michigan in winter as it gives off its heat and the attendant snows, unless it's frozen solid like a brick. And that makes all the difference to berry, grape, apple and other growers who proliferate on the warmer side of the lake and depend on the warmth and the snow cover to protect their plants.
