Having a mild day in the 50's on Thanksgiving Day is relatively rare, looking at the historical record back to 1872. A maximum of 50 or more has happened only ten times in 140 years, or about once every 14 years or so. The warmest Thanksgiving Day is a tie of 62 degrees set in 1914 and 1922. The mildest recent Thanksgiving Day is 59 degrees on November 24, 2011. This was the fourth warmest Thanksgiving back to 1872 for the Twin Cities.
On the other side of the spectrum, it is common to have a high temperature below 32. The average Thanksgiving Day temperature is right around freezing. What about extremely cold Thanksgivings? Looking at the past 140 years, It is a little more likely to have a minimum at or below zero on Thanksgiving Day, as it is to have a maximum of 50 or above. Below-zero lows have occurred twelve times in the past 140 years. The coldest Thanksgiving Day minimum temperature was 18 degrees below zero on November 25, 1880. The coldest high temperature was one below zero on November 28, 1872. The last time it was below zero on the morning of Thanksgiving was in 1985, with eight below zero.
Measurable snow fell on 27 of the past Thanksgivings back to 1884, about every five years or so. The most snow that fell on Thanksgiving was five inches in 1970. The last time there was measurable snow on Thanksgiving was in 2007 with .2 (two tenths of an inch) of snow. Historically, about one in three Thanksgivings have at least one inch of snow on the ground. The deepest snow pack is a tie with 1921 and 1983, both with 10 inches on the ground by Turkey Day."

Superstorm Sandy created tons of debris that towns in New York and New Jersey are still struggling to dispose of weeks later. Three weeks in, the round-the clock effort to remove storm rubble has strained the resources of sanitation departments and landfill operators, and caused heartaches and headaches for thousands of families."

Lukewarm November. 70 at Rochester...on November 21? Not bad, considering we're a month away from the winter solstice, when the sun is as low in the southern sky as it ever gets. The "cool spot" was International Falls at 50, 56 St. Cloud and 69 at Redwood Falls.

President Obama's False Choice: Global Warming Or The Economy? The story from Huffington Post; here's an excerpt: "...The president is understandably concerned that the American public elected him with a mandate to focus on jobs, growth and the economy, and any deviation from this is, as he says, not something "I would stand for." However, the very jobs he hopes to create and the economic engine he hopes to stoke will be influenced by the impacts of climate change. According to a report in Time, the damages caused by Hurricane Sandy will cost from $30 billion to $60 billion. Clearly, the world cannot afford too many super-charged storms. Meanwhile, record heat plagued most states during the summer of 2012, leading to a drought that might be the most costly natural disaster in history. There are brand-new jobs to be had in new green energy technologies. Plus, according to the respectable Stern Review, spending just 1 to 2 percent of GDP today (about $900 per person per year, or the price of a cell phone plan) will take care of current emissions. Waiting a few decades means the cost goes up to a far more painful 20 percent. In simple terms, if we don't deal with the issue of climate change it will hurt jobs, growth and the economy, saddling not just our generation, but our children's generation as well, with debt and consequences..."

More Fallout From Urgent World Bank Climate Report. Live Science has an interesting quote from climate scientist Michael Mann: "..Climate deniers often claim that solutions to global warming are part of a "global socialist agenda," Mann told LiveScience. "The fact that the World Bank — an entity committed to free market capitalism — has weighed in on the threat of climate change and the urgency of acting to combat it, puts the nail in the coffin of that claim," he said.
A changing world
The report, issued by the Potsdam Institute for Climate Impact Research and Climate Analytics for the World Bank, urges nations to work to prevent the Earth from warming 7.2 degrees Fahrenheit (4 degrees Celsius) past preindustrial averages. Already, global mean temperatures are running about 1.3 degrees F (0.8 degrees C) hotter than before the onset of the industrial revolution..."

- Extreme heat waves, that without global warming would be expected to occur once in several hundred years, will be experienced during almost all summer months in many regions. The effects would not be evenly distributed. The largest warming would be exptected to occur over land and range from 4° C to 10° C. Increases of 6° C or more in average monthly summer temperatures would be expected in the Mediterranean, North Africa, Middle East and parts of the United States.
- Sea level-rise by 0.5 to 1 meter by 2100 is likely, with higher levels also possible. Some of the most highly vulnerable cities are located in Mozambique, Madagascar, Mexico, Venezuela, India, Bangladesh, Indonesia, the Philippines and Vietnam.
