♦ IPCC TAR (2001): “Milder winter temperatures will decrease heavy snowstorms”
♦ Kunkel et al., 2002: “Surface conditions favorable for heavy lake-effect snow decreased in frequency by 50% and 90% for the HadCM2 and CGCM1 [models], respectively, by the late 21st Century. This reduction [according to models] was due almost entirely to … an increase in average winter air temperatures.”
♦ IPCC AR4 (2007): “Snow season length and snow depth are very likely to decrease in most of North America”
♦ Kapnick and Delworth, 2013: “In response to idealized radiative forcing changes, both models produce similar global-scale responses in which global-mean temperature and total precipitation increase while snowfall decreases. … By using a simple multivariate model, temperature is shown to drive these trends by decreasing snowfall almost everywhere” (press release) “In North America, the greatest reductions in snowfall will occur along the northeast coast, in the mountainous west, and in the Pacific Northwest. Coastal regions from Virginia to Maine … will get less than half the amount of snow currently received.”
The reality: Blizzard activity jumps fourfold
For example a paper by Coleman and Schwartz, 2017 revealed 713 blizzards over the 55 years with 57 federal disaster declarations resulting. Of these 57 declared disasters, more than a half have occurred since the year 2000.
Finally, a study conducted by Hatchett et al., 2017 found a “winter snow level rise in the northern Sierra Nevada from 2008 to 2017”. Sea surface temperatures offshore California were observed to be related to snow cover.

This one is the for our local environmentalist, a remarkable personal story of how a Colorado environmentalist came to embrace the very thing she had been programmed to hate: oil and natural gas extraction.
A heartwarming story of a woman who changed her mind without changing her environmentalist values.
There is absolutely nothing unusual about today’s so-called global warming or if you prefer climate change.
Look at how many periods of warmth our planet has enjoyed during the past 10,000 years alone.
Civilizations flourished during those warm periods and collapsed when they ended.
- Did humans cause the Minoan warm period of about 3,300 years ago?
- Did humans cause the Roman warm period of about 2,100 years ago?
- Did humans cause the Medieval warm period of about 1,000 years ago?
- What about all of those other warm periods? Should we blame Fred Flintstone?
Now, look at where we are today at the far right side of the graph. Note how warm the past has been.
If the downward trend in temperature of the past 3,300 years continues, we could be in a heap of trouble. While our leaders keep on wringing their collective hands over global warming, we could be blindsided by an ice age.
All the lefty talk about human-caused global warming is sheer nonsense. The record shows that both periods of warmth – and periods of cold – hit our planet with almost consistent regularity.
The above chart is based on data from GISP2 (Greenland Ice Sheet Project 2). GISP2 drilled cores into the Greenland ice more than 3000 meters (almost 2 miles) deep, allowing scientists to study climate variability for the past 125,000 years.
H/T to Ice Age Now for the information.
Early in my blogging on global warming and then climate change the lefty anthropogenic warmers insisted that we have never experienced this range of temperature before. My position was that the Medieval Warming Period temperature was on par with or warmer than the current global temperatures. The anthropogenic warmers positions were that the MPW was just a regional anomaly, it was not global, therefore was not reliant to the global temperature discussion. About ten years have passed and over a 1,000 studies now validate the global reach of the MPW.

It appears that the lefty anthropogenic warmers were wrong. AGW was global and calls into question the argument we are experiencing unusual warming over the last 20 years. We are not, it has happened before and will happen again. There is nothing unusual about the current warming, thus casting doubt on anthropogenic warming.
The Pacific nation of Tuvalu—long seen as a prime candidate to disappear as climate change forces up sea levels—is actually growing in size, new research shows.
A University of Auckland study examined changes in the geography of Tuvalu’s nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery.
It found eight of the atolls and almost three-quarters of the islands grew during the study period, lifting Tuvalu’s total land area by 2.9 percent, even though sea levels in the country rose at twice the global average.

This is an example of how NOAA produces global warming, they just change the data to suit their political needs. Here is one example from Maine using NOAA’s own data.
This Maine data was captured in 2013. Note no warming trend.
After a major upgrade to the NOAA database, the warmest year was reduce by 5 degrees an assigned a middle of the pack position. Now we have an NOAA generated warming trend for Maine winters. See how the warming magic happens, just adjust the data. Make the past colder and the present warmer, and all of a sudden we have global warming.
See how easy it is to fool people on the left who refuse to look at the historical data, choosing instead to rely on appeals to authority arguments. An authority that can adjust the data to fit the politics of the day.
The mean sea level (MSL) trend at Wismar, Germany is +1.43 mm/year with a 95% confidence interval of ±0.11 mm/year, based on monthly mean sea level data from 1866/1 to 2015/12.‡ That is equivalent to a change of 0.56 feet in 100 years. (R‑squared = 0.368)
The plot shows the monthly mean sea level without the regular seasonal fluctuations due to coastal ocean temperatures, salinities, winds, atmospheric pressures, and ocean currents. By default, the long-term linear trend is also shown, in red, along with its 95% confidence interval. The plotted values are relative to the most recent Mean Sea Level datum established by NOAA CO-OPS.
