Is global warming to blame for rising temperatures in Michigan?

By Cole Bertsos

When temperatures turn extreme, two questions are bound to be the subject of debate: Are our temperatures getting warmer and, if so, is it because of global warming? MLive took a look at trends in three Michigan cities to give readers some context and perspective.

Heat and drought led to many poor harvests last year.

The data showed that Detroit is in a very strong warming trend — in fact, beginning with 1983, the city is in the warmest period it has had since record-keeping began. The study showed similar results for Flint, with the high temperature rising 2.57 degrees beginning in 1982.

Grand Rapids also was studied but unlike Flint and Detroit, the city had more temperature fluctuations since record-keeping began and did not experience a sharp warming in temperatures until 1998, according to the MLive report.

MLive's story also asks readers to determine what they consider a s significant rise — is two and a half degrees over 30 years a big deal? Over 60 years?

Let's see.... Increasing temperatures are caused by global warming. Decreasing temperatures are caused by global warming. Droughts are caused by global warming. Increased precipitation is caused by global warming. Asteroids are caused by global warming. What's next, the drift of the magnetic poles is caused by global warming?

BBC Q & A with Phil Jones B - Do you agree that from 1995 to the present there has been no statistically-significant global warming "Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level. The positive trend is quite close to the significance level. Achieving statistical significance in scientific terms is much more likely for longer periods, and much less likely for shorter periods." What happened to the scary looking HOCKEY STICK curve that was going to lead to 20 feet sea level rise. It was made up. It's a hoax to scam money from the public. http://news.bbc.co.uk/2/hi/8511670.stm Phil Jones got caught manipulating the temperature data so he claims the data was lost. How convenient. I am amazed people are still being fooled and believe CO2 causes global warming. http://www.guardian.co.uk/environment/2010/feb/15/phil-jones-lost-weather-data

When it's extremely hot it's global warming. When it is extremely cold it is global warming. They can't lose. Even though a few years ago some warmists were predicting we'd have no more snow. Just about all other predictions they made also turned out to be false. Yet, some people continue to cling to this faux science. It is truly amazing how gullible people are.

What the graphs clearly support is that in the 70's there was a downward trend that caused some scientists to predict that we were heading into another ice age. Beware of the scientist who needs to create a reason for additional funding of his/her field.

Here is a site that explains how global warming is creating our cold spell. http://www.climatecentral.org/news/from-heat-wave-to-snowstorms-March-weather-goes-to-extremes-15763 It is something called the Artic Oscillation that has put a high-pressure spot over Greenland. Here is a (chilling) quote: "A study published in 2012 showed that by changing the temperature balance between the Arctic and mid-latitudes, rapid Arctic warming is altering the course of the jet stream, which steers weather systems from west to east around the northern hemisphere. The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere, due to a combination of human emissions of greenhouse gases and unique feedbacks built into the Arctic climate system. The jet stream, the study said, is becoming "wavier," with steeper troughs and higher ridges."

TommyJ - Jeff Masters has a great blog entry on this: http://classic.wunderground.com/blog/JeffMasters/comment.html?entrynum=2370 The cold is because the jet stream is stalled, sending cold arctic air into the midwest, and warm gulf air into northeastern Canada & western Greenland. These stalling atmosphere Rossby waves were the reason for the heatwave last year too, though the jetstream was shifted so we got the bubble of heat last year. Why the stalling Rossby waves? They think it's the melting arctic. And the melting arctic? Climate change.

This data shows two temperature cycles for three cities. Flint's data shows the second cycle had a lower peak. Detroit's data shows the second cycle had a higher peak. The Grand Rapids data looked similar for the two cycles. The article askes if the higher temperatures for our state are due to global warming, but the data doesn't even prove our state temperature cycles are raising. Very poor statistical analysis and a biased interpretation to cap it off.

The last glacial period in Earth's current ice age ended about 10,000 years ago and its climate has been warming ever since. Not surprisingly, Mars is also warming and its CO2 ice cap is receding. Shall we blame Mars' warming on Spirit, Opportunity, Sojourner, Pathfinder, and Curiosity? Global warming has reduced Michigan winter to slushy mud, but chacun a son goo.

"MLive's story also asks readers to determine what they consider a s significant rise — is two and a half degrees over 30 years a big deal? Over 60 years?" Even if it is true there were temperature gains in a few cities in Michigan, those were more than offset by record lows in parts of Europe. It is a terrible scientific method to use a few cities to claim there is global warming. See how it is so easy to manipulate the global temperature data.

Which is exactly why scientists use global temperatures. The increase in temperature in many cities is NOT offset by low temperatures elsewhere. That's the point.

Please stop the propaganda. The perpetrators of man-made global warming have already admitted the temperature data was minipated and there is no global warming. Plus, even if there were warming, there are many benefits of a warmer climate (i.e. longer growing season) and, as in the past, humans, animals, plants and insects will adapt. Don't these warmists believe in evution? Sea levels are not going to rise 20 feet as Al Gore claimed. That is pure fear mongering for financial gains.

@ G. Orwell You are trying to refute legitimate scientific sources using a blog with topic categories of "Arrest Obama", "Evolutionism", and "Obama's SS Czars". Wow. It saddens me that the concept of actual scientific sources is completely foreign to some. For the record, the "No global warming in 16 years" is a claim that could be debunked by a fifth grader. It's simply the result of cherry picking data. There is a clear warming trend that has continued over that time period. These kinds of "arguments" attempting to refute global warming are so elementary, so devoid of any real understanding of climate and temperature data, that it makes the people who study this stuff just shake their heads. This is the kind of stuff that would get a high school student a D in science classes.

Around thirty years ago when the whole global warming alarmism game was starting I took the highest temperature rise the greenies predicted. Worse case scenario. It was clear that we would all die a horrible death by roasting. How bad would it be? The numbers then meant that Detroit and Ann Arbor would be as intolerable as that horrid tropical cesspool - wait for it, AA would be as hot and unliveable as Dayton, Ohio!!! The numbers have been eased back at bit and at the worst global warming scenario it would probably make AA as hot and desert like as maybe Dundee. Oh the humanity! How will we cope?

In fact, it's a couple of degrees warmer than the bottom of the last cooling trend. Why wouldn't it be? We have 130 years of reliable temperature data. The Earth is about 4.5 billion years old. Alarmists from the media speculating on something they know nothing about is not helpful in the slightest.

I concur... I have been skeptical of this "Global Warming" issue because of the simple reason that we do not know what the climate is like for North America, let alone have reliable data around the world past the last few millenia. A lot of what we might know is from the traditional stories and written accounts which talk more about people and events than the weather. Who knows what North America was like 400, 500, 1,000 years ago let alone the past 5,000 years? This might just be a cyclical trend that we have yet to discover (we are just coming out of a Little Ice age in the past few centuries). I will agree that some of our modern practices aren't helping by putting certain things into the ozone and into the ground and what not... ...but one volcano that blows its top puts more bad stuff into the atmosphere than what we've done since the 1750s.
