The idea that climate change is producing heat records across the Earth is among the most egregious manipulations of data in the absurd global warming debate.
Americans receive a daily barrage from the fake news media and climate “experts” reporting that each and every day, week, month or year is the hottest on record due to global warming. On Feb. 7, several major newspapers carried stories of the declaration by NASA and NOAA that the past five years have been the warmest on record.
Sadly, these supposed experts use mathematical equations that do not jibe with reality over the past 140 years.
The same climate experts warn that record heat is just the tip of the iceberg. We are constantly told that global warming is the root cause behind any and all weather events that are extreme, destructive, unusual or uncomfortable.
Many of these fear mongers also say we should stop burning fossil fuels that are causing this mayhem.
Is the Earth truly experiencing the hottest weather on record?
Actual weather records over the past 100 years show no correlation between rising carbon dioxide levels and local temperatures.
However, climate change alarmists always find somewhere on Earth where temperatures are higher than ever. The focus is always on isolated temperatures that have reached all-time highs while the same reports ignore all-time record lows. These zealots would like you to believe that due to fossil fuel emissions, summers are now longer and hotter while winters are shorter and milder.
Yet, the actual temperature records tell a very different story. Did the Earth experience its highest temperature ever this year? The answer is no.
The highest temperature ever reported was 136 degrees Fahrenheit in Libya in 1922. The record high temperature for the United States was 134 degrees Fahrenheit in Death Valley, California, in 1913. Fossil fuel emissions in 1913 and 1922 were negligible compared to today.
The coldest temperature ever reported was 129 degrees below zero Fahrenheit in Vostok, Antarctica, in 1983, when Carbon dioxide emissions were five times higher than in 1913. The coldest temperature in the lower 48 states of minus 64 degrees Fahrenheit was recorded in 1996 in Embarass, Minnesota. Did the media and climate scientists warn that this low temperature indicated that we are headed for another Ice Age?
The maximum reported difference between high and low temperatures at a single location is 188 degrees Fahrenheit (from minus 90F to plus 98F) in Verhoyansk, Siberia. In fact, record changes of highs and lows have occurred in 22 U.S. cities on a single day. For example, in 1989 the temperature in Alamosa, Colorado, varied between a low of 35F and a high of 91F for a temperature swing of 56 degrees F.
We hope these examples, right out of the weather record books, compiled by C.C. Burt in his book “Extreme Weather Changes,” will help you to understand the scams alarmists are trying to pull. These examples all illustrate that cherry picking record high temperatures in isolated locations tells absolutely nothing about the Earth’s climate.
The strongest heat wave ever recorded occurred in July 1936, generating high temperatures in half of America’s 50 states. In 1935, fossil fuel emissions were 96 percent lower than today. America’s coldest year occurred in 1899, when temperatures dropped below 0 F in all 50 states.
Interesting that the figure above shows the most severe historic cold wave during the past century took place in 1936, which was the same year when the strongest heat wave took place. In terms of general behavior, the global warming alarmist prediction is that as time progresses and fossil fuel emissions increase, the number of record highs should increase and record lows should decrease. However, these trends do not exist and the data dispels, rather than supports, the global warming hypothesis.
Concurrently a compilation of all days since 1915 when temperatures exceeded 90F shows them decreasing with time rather than increasing in Figure 2.
The heat wave experienced in the 1930s and 1950s are clearly evident here. Once again, the data does not support the claim that the United States is hotter than ever as a result of rising Carbon dioxide levels.
From 1970 until 1998 there was a warming period that raised temperatures by about 0.7 F that helped spawn the global warming alarmist movement. However, since 1998, little warming has occurred while carbon dioxide emissions continue to increase. This is totally consistent with variations in the amount of heat the Earth receives from the Sun.
These facts are completely supported by 4,000 ocean floats which measure ocean temperatures at a variety of depths. This data at argo.ucsd.edu measures the oceans where climate-induced temperatures occur.
Isn’t it time to start ignoring the calamitous annual claims that this is the hottest year on record? It just ain’t so.
