I grew up in Ohio. As such I was aware that when white man first arrived most of the state had such a dense tree covering that it made traveling extremely difficult unlike the Great Plains with their wide open spaces. As white people moved in; massive amounts of trees were cut. It was popular in those days for common people (amateur scientists) to take daily temperature readings. As thus one can correlate the cutting of trees with a rise in average temperature readings. There has also been a corresponding lowering of average humidity. Ive spend a good portion of my adulthood living in Colorado. Eastern Colorado is dry grassland, almost to the point of being a desert. The Front Range area is on the edge of this dry grassland leading into the mountains. In the Denver metro area a phenomenon simular to that in Ohio but the reverse happened. As the Denver area grew people planted trees, shrubs, and lawns. With the increase of trees there was a corresponding decrease in the average temperature and a rise in the average humidity. Thus, in both Ohio and Colorado there is historical documented proof that human activities have an effect on the climate. In Colorado, in the Denver area, it used to be that every year there would be one to three weeks, in January, were the temperatures would drop below 0 every day. That doesnt happen any more. Likewise there would be around a dozen days in the summer when it would get above 90. Now it is like 40 days every summer. Clearly the Denver area has seen rising temperatures. This last winter people were saying that it was the worst in 30 in years. Denver hasnt had a worse in thirty years winter for more than 30 years. Dont believe me? Go to anywhere on the web that provides historical weather data and you will see that I am absolutely correct on this. During the past winter, at least in the eastern half of the country, there was far more snowfall than what is normal. But if one looks closely they will see that the temperatures werent any colder than before. It was only that there was more moisture in the air, thus more snow. Snow cover actually makes the earth under it warmer than if the ground were bare given the same air temperature. Anyone who knows anything about physical science knows that the warmer the weather the greater the evaporation rate. As thus a very easy testable prediction of global warming is that there should be a corresponding rise in evaporation of water from the oceans and thus more moisture available for rain and snow. Isnt that what we saw this winter? The amount of energy, from the sun, falling on the earth is rather constant. Thus if one spot becomes overly cold it is counterbalanced by other areas becoming warmer. Thus when the winter was at its worse in the US, elsewhere, in Europe, in the Pacific Ocean, the temperatures were above average, as they were here in Oregon. Oh and by the way; it is obvious to be that all of the stick your head in the sand and pretend global warming isn't happening propaganda is a function of those not wishing to obey environmental laws. Polluting has consequences.

this past winter was the worst in 35 yrs in my area as well, whereas 35 yrs ago it was routine...this winter was an anomaly, not part of a cooling trend...deniers don't comprehend a single data point can not indicate a trend(that single point being one year), something I've repeatedly pointed out to them many times on this forum but their ability to grasp that concept is challenging for them...
Here, I looked up the first freeze data for Denver: First Freeze Last 10 Years: October 4, 2013 October 5, 2012 October 17, 2011 October 27, 2010 October 2, 2009 October 13, 2008 October 8, 2007 September 18, 2006 October 5, 2005 October 14, 2004 Looks remarkably consistent.
Greatest Seasonal Snowfall: 118.7 inches 1908-1909 Least Seasonal Snowfall: 21.3 inches 1888-1889 hmm.........I still don't see your point.
Spring Last Freeze Information Earliest Date of Last Freeze: April 5, 1977 Latest Date of Last Freeze: Jun 8, 2007
You are looking at too small a set of data and a set that has nothing to do with what I have been saying. In the Denver area there used to be more days below 0 than there now are and there are more days over 90 than there used to be. For instance this past January there was only one day where the temperature dropped below 0. In the 70s it was common for there to be a week or two where it would drop below 0.
Really over a hundred years of data and that ain't enough for you? How old are you 200 hundred? Your claim was refuted. I provided the details from a weather web page that has the records. Now you say it's too small? LOL. silliness I can't stand the silliness.
