Minnesotans for Global Warming
A new study finds that Minnesota's climate has warmed significantly since 1970.
Coming on the heels of a remarkably warm winter and spring not even included in the data, a new study put together by the Climate Central non-profit reveals that Minnesota's climate has warmed significantly since 1970.

The study found Minnesota's average low temperature increased at a per-decade rate of 0.748 degrees from 1970 through 2011 -- the largest increase of any state. Over the same timeframe, Minnesota's average daily temperature increased by 0.620 degrees per decade, the third-largest increase in the country behind only Arizona and Michigan.

Overall, the study found that whether you look at the past century or just the last 40 years, the states that have warmed the most are northern-tier states like Minnesota, Wisconsin, Michigan, and Maine, and southwest states like Arizona and New Mexico. The states that warmed the least are found in the southeast, like Florida and Alabama, and central midwest, like Iowa and Nebraska.

Three states -- Arkansas, Georgia, and Alabama -- had small average temperature decreases over the past century, but all 50 states have warmed since 1970.

From 1912 through last year, the average temperature in the continental US warmed by about 1.3 degrees Fahrenheit. Study authors write that "the pace of warming in all regions accelerated dramatically starting in the 1970s, coinciding with the time when the effect of greenhouses gases began to overwhelm the other natural and human influences on the climate at the global and continental scales."

If anything, the warming trend has accelerated thus far in 2012. From today's Star Tribune:
This spring was the warmest in Twin Cities history.
Meteorological spring in the Twin Cities was the warmest on record -- though it was for the entire United States as well. Minnesota had its warmest March ever, and May was the 12th-straight month with an average temperature above the 30-year normal. [The assistant state climatologist] said he knows of no other such stretch on the books.
Richard Wiles, Climate Central's vice president for strategic communications, speculated to MPR about how continued warming could impact Minnesota.

"Potential mass extinctions, sea level rise, which doesn't affect Minnesota, but potential areas of chronic drought where we may not be able to grow food for people the way we do now," Wiles said. "The price of food could increase dramatically."

Everybody seems to forget that in the 70's, the rage was global cooling. It was in the news just as much as global warming is today, warning us of the impending new ice age. Who remembers that???

.... data has only been recorded since the 1860's. Second warmest was embellished with use of the word "like". There was a consensus among meteorologists as well as the farmers almanac, not only one person. Ice caps are actually coming back in places, they just don't tell you that. The earth is smart. It has always balanced itself out after any catastrophic event, ,warming trend, or cooling trend. There are some instances in life where it seems like god is responsible for them, but many other times, it doesn't. To very prematurely assume the god of climate change is responsible is the same concept. Your last paragraph is ironic: if we were allowed to actually progress we wouldn't be having this discussion in the first place. We'd have free atmospheric energy or perhaps some technology that is newer and better, industrial hemp would be legal everywhere, and instead of paying farmers subsidies to burn marketable crops or grow unmarketable crops on purpose, we'd be able to feed the whole world no problem.

Again, you are taking moves from the religious zealot playbook and cherry picking.  Or claiming that because one scientist failed to predict the coming winter correctly that all scientists are incapable of looking back at actual climate changes over time (I wonder if you see any irony in a climate change denier using the 2nd warmest winter on record as an example of your point).  There is no dispute that the earth has been warming for thousands of years, the question is why the sudden extreme acceleration.  What might be the cause of unprecedented oceanic warming resulting in rapid glacial retreat and decreased quantities of yearly sea ice.  What might be causing the extreme change in surface water acidity or what might be responsible for the increase in extreme weather events globally (longer droughts, more severe rain and snow events)?  How about the change in animal migration and plant growth patterns?   People that are afraid of the difficult choices required to learn and progress are always insisting there isn’t a problem.

 @ Effeminate - The DO discuss it.  And it is equally clear that *after* that exceptionally warm period was an ice age that devastated the balance of life on the planet.

They only pay attention to info that supports their cause. Ice core samples show the world was much warmer millenia ago, but pro man made global warming scientists won't mention that. Also, the same science that says man made global warming is real is also the same science that predicted this past winter to be the coldest in years, yet it was like the second warmest on record. Trying to predict accurately years in advance when they can't get the next year right, and you have faith...You don't have to be smart to figure these things out, just observant and not afraid to ask questions

You vitajex are an idiot.  You have to be just so fucking tired.  I mean really.  It's got to be just so fucking tiring!

I would argue that you have to be a religious zealot to deny climate change.  Who else has the ability to stare reasonable science based conclusions in the face and declare “despite the evidence I have faith in the opposite”

Bill O'Reilly is a religious zealot, just like man made global warming enthusiasts are religious zealots. Same thought process.

kirk, I'm not sure I get it... it sounds like you're saying the tax payers funded this study because they (we) have a pro global warming agenda.
