Global Warming Surges: From 1850 To The Current Climate

A very quick overview of the global temperature evolution.

According to climate science researchers, there have been several surges in global temperatures to higher levels since 1850.

By plotting the 1850 to July 2023 monthly NOAA global anomalies, visually it becomes clear when the temperature surges upward took place.

There do exist different numeric and statistical manners in which to identify temperature shifts, but the temperature level shifts on this chart were identified simply by the self-evident grouping of the majority of anomalies for a given time period. (See anomalies grouped within black dashed lines.)

A summary of the five temperature periods from the chart:

Period1: From January 1850 through April 1937, this was an extended time span for both cooling and warming bursts but overall this 87+ year period experienced a small cooling trend of -0.01°C/decade. Notice that over the period's last 20 years, the global anomalies were rising.

Period2: Global temperatures were shifted up to a new base level from May 1937 through October 1976 (39.5 years). Despite the prominent shift up at the beginning of the period, there was a small cooling trend of -0.02°C/decade for the entire period.

Period3: From November 1976 through December 1996 (20.2 years), the first extended modern warming trend was established. There were two brief cooling spans during this period but overall the warming trend was +0.10°C/decade.

Period4: From January 1997 through August 2014 (17.7 years), the warming trend increased to +0.17°C/decade level, again with two cooling spans intermixed during the 17+ years.

Period5: From September 2014 through the end of July 2023 (8.9 years), the warming trend has been significantly reduced - almost being flat - when compared to the two prior warming periods.

While there are those who suggest that CO2 emissions from fossil fuel combustion are to blame for the significant shifts in global temperatures over the five different periods, the empirical science does not support the hypothesis that a trace atmospheric gas can cause abrupt changes.

A more likely explanation for the shifts is the natural oscillations and weather variations that are part and parcel of the world's climate.

For example, the well-known climate warming oscillation called 'El Niño' has taken place during all the periods at an average frequency of every five years. Climate researchers have noticed that climate temperature step-upward shifts seem to follow significant El Niño episodes.

Finally, it is possible to reduce the five periods to two very long-term periods: one cooling/flat and one warming. This can be accomplished if one strictly uses the change of the slope of the linear trend from negative to positive at a specific point over the entire length of time since 1850.

For the first long-term period - from1850 to December 1940 - there was a very slight negative slope (i.e., cooling). That amounts to 90.9 years with a trend that was practically flat, thus indicating that there had not been any significant warming over the 90+ years since the Little Ice Age (LIA), which is thought to have ended around 1850.

Using NOAA data, the very long-term positive warming trend starts in January 1941 and continues for 82.5 years, until the end of July 2023.

And if NOAA records are accepted as a trustworthy history of world temperatures, it would then be logical to conclude that a robust, significant temperature recovery from the extended LIA cold really did not begin until the early 1940s.

"Climate Emergency" Disinformation: Pushing Visual Fear-Propaganda

It is regrettable that so many politicians today feel compelled to support particular agenda narratives laced with disinformation that is being created by a number of sources, including those of misguided "expert" scholars, scientists, activists, and journalists.

The false narrative has grown so obvious and apparent during the COVID era that large segments of the public are rejecting the blatant propaganda. Many believe that this is because the ongoing disinformation is being used to force the public to comply with authoritarian, anti-democratic laws and regulations that have been developed by the "experts."

And much like the disinformation of the COVID narrative, the ruling elites are using the same propaganda techniques for the issue of climate change (aka global warming, climate emergency, climate crisis, existential threat, etc.).

Chart #1 (click on to enlarge)

As an illustration, the ruling class is currently spreading false information about "global boiling" in an effort to persuade the populace that major reductions in the use of fossil fuels are required in order to "save the world."

The disinformation campaign frequently uses climate science graphs, like this global anomaly chart from NASA/GISS, to incite widespread public angst.

The NASA/GISS graph (Chart #1) created by the experts depicts scary, rapidly rising monthly global temperature anomalies and displays an anomaly range from -1.0 to +1.5°C on the left axis for the past 170+ years.

But who lives in a location where temperatures (actual observed thermometer values) only range 2.5 degrees in the course of a year?

The majority of people on earth typically live in one of the 90 some nations with a low to high temperature range of the thermometer that is greater than 38 degrees every year. For instance, China's climate has an average daily low in January of -10.6°C and an average high in July of 39.8°C, which is roughly a 50-degree range for a country with 1.4 billion people.

Chart #2

Since it is not practical for this article to show a thermometer degree plot for each of those 90 countries, instead chart #2 plots both the global monthly thermometer and global anomaly temperature measurements using a temp range from -2.0 degrees Celsius (28.4F) to 36 degrees Celsius (96.8F).

Chart #2 provides the real-world temperature context that the public is missing when presented with a simple anomaly chart, such as the one produced by NASA/GISS.

In addition, the common anomaly temperature published by NASA/GISS and other climate research agencies do not include the atmospheric CO2 growth that is claimed to be the cause of the "global boiling."

Chart #2 does include the CO2 growth, making it possible for the public to assess the governing elites' claims that the normal person's use of fossil fuels is actually producing a climate emergency, a climate crisis, an existential threat, global boiling, and etc.

It is very likely that the average person viewing figure #2 would not draw the same conclusion as the experts that CO2 warming is about to bring an end to civilization.

In conclusion, a rational discussion about solutions rather than authoritarian decrees could start if politicians and their "experts" gave the public the necessary information about the climate change challenges in the proper context and avoided the easily debunked fear-mongering hyperbole and disinformation.
