Chicago’s hottest day was 109 degrees on July 24, 1934. Chicago’s hottest night was 85 degrees on July 29, 1916. Illinois July temperatures have been on the decline since 1895, and particularly since the 1930s.

ILLINOIS Climate Summary

National Academy Of Sciences : 1975

“there seems little doubt that the present period of unusual warmth will eventually give way to a time of colder climate, but there is no consensus as to the magnitude or rapidity of the transition. The onset of this climatic decline could be several thousand years in the future, although there is a finite probability that a serious worldwide cooling could befall the earth within the next 100 years“.

But …. Tamino said that the modern era of global warming didn’t begin until 1975.

Global warming activist James Hansen has of course erased the 1910 to 1940 warmth.

“As respondents’ science literacy scores increased, their concern with climate change decreased,” the paper, which was funded by the National Science Foundation, notes.

Heavy ice could delay start of Shell Alaska’s Arctic drilling
May 28, 2012

The heaviest polar ice in more than a decade could postpone the start of offshore oil drilling in the Arctic Ocean until the beginning of August, a delay of up to two weeks, Shell Alaska officials said.

The New York Times continues to spread misinformation about Polar Bears

Polar Bear populations have tripled over the last few decades, and may currently be the largest in the last 100 years.

1975

Having risen about 1.1 degrees C. between 1885 and 1940, according to one estimation, the temperature has already fallen back some 0.6 degrees, and shows no signs of reversal.

SCIENCE NEWS interviewed C. C. Wallen, chief of the Special Environmental Applications Division, World Meteorological Organization, at the wmo headquarters in Geneva. The cooling trend observed since 1940 is real enough, he says ……

the cooling since 1940 has been large enough and consistent enough that it will not soon be reversed, and we are unlikely to quickly regain the “very extraordinary period of warmth” that preceded it. Even this mild diagnosis can have “fantastic implications” for present-day humanity, Wallen says.

Hansen has been steadily cooling the 1930s since he got control of the temperature database, and now shows the 1930s as only slightly warmer than the very cold 1970s.

The graph below shows how Hansen corrupted the pre-1940 Northern Hemisphere temperature record – to eliminate data which contradicts his endless fear mongering.

Newspapers never forget what Hansen wants us to.

In 1987, Ronald Reagan stood in Berlin and said “Tear down this wall!”

Two years later, NOAA did a study concluding that there had been no warming in the US since 1895.

U.S. Data Since 1895 Fail To Show Warming Trend
By PHILIP SHABECOFF, Special to the New York Times
Published: January 26, 1989

After examining climate data extending back nearly 100 years, a team of Government scientists has concluded that there has been no significant change in average temperatures or rainfall in the United States over that entire period.

While the nation’s weather in individual years or even for periods of years has been hotter or cooler and drier or wetter than in other periods, the new study shows that over the last century there has been no trend in one direction or another.

The study, made by scientists for the National Oceanic and Atmospheric Administration was published in the current issue of Geophysical Research Letters. It is based on temperature and precipitation readings taken at weather stations around the country from 1895 to 1987.

U.S. Data Since 1895 Fail To Show Warming Trend – New York Times

In 1999, Hansen concluded the same thing

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath…..

in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country

Less than a year later, Hansen and Tom Karl rewrote the US temperature record – to produce more than 1C warming from 1895 to 1987.

Many people gave their lives to protect America from the Soviet Union. Little did we realize that people of the Soviet mentality were taking over our own government.

In 1975, before the consensus had received their mandatory James Hansen lobotomy –  climate scientists understood that global cooling causes extreme weather, and global warming causes mild weather.

The principal weather change likely to accompany the cooling trend is increased variability-alternating extremes of temperature and precipitation in any given area-which would almost certainly lower average crop yields. The cause of this increased variability can best be seen by examining upper atmosphere wind patterns that accompany cooler climate. During warm periods a “zonal circulation” predominates, in which the prevailing westerly winds of the temperate zones are swept over long distances by a few powerful high and low pressure centers. The result is a more evenly distributed pattern of weather, varying relatively little from month to month or season to season. During cooler climatic periods, however, the high-altitude winds are broken up into irregular cells by weaker and more plentiful pressure centers, causing formation of a “meridional circulation” pattern. These small, weak cells may stagnate over vast areas for many months, bringing unseasonably cold weather on one side and unseasonably warm weather on the other. Droughts and floods become more frequent and may alternate season to season, as they did last year in India. Thus, while the hemisphere as a whole is cooler, individual areas may alternately break temperature and precipitation records at both extremes.
