A trend analysis of the RSS satellite dataset would reveal a modest global cooling since January 2000, while at the same time, vast amounts of human CO2 emissions were injected into the atmosphere having zero warming impact - in addition, reviewing the empirical measurements since the beginning of the satellite era indicates that huge record-setting CO2 emissions have not caused the IPCC's predicted "accelerating," and "dangerous" global warming, instead temps decelerated

The adjacent chart plots the highly variable atmosphere temperature anomalies, segmented to depict temps prior and subsequent to the 1997-1998 Super El Niño. The grey columns represent approximate human CO2 emissions (gigatons) during each segment.
The pink spike segment of the anomalies represents the beginning, the end and peak of the Super El Niño. This natural phenomenon began its climb to a peak from a low point during March 1997, and then finally collapsed to a low point during June 1999 - a total of 27 months.
The 219-month temperature segment on the left (starting January 1979 thru March 1997), prior to the Super El Niño has the following attributes:
- A linear global warming trend equal to +0.7°C per century
- A lot of temperature variability, with a range of 0.8°C - constant changes, non-stable
- An average anomaly equal to -0.036°C
- A moving 36-month anomaly average that was increasing prior to the Super El Niño spike
- An addition of approximately 410 gigatons of human CO2 emissions
The 168-month temperature segment on the right (starting July 1999 thru June 2013), post the Super El Niño has the following attributes.
- A linear global warming trend equal to +0.2°C per century
- A lot of temperature variability, with a range of 0.7°C - constant changes, non-stable
- An average anomaly equal to +0.23°C
- A moving 36-month anomaly average that currently is decreasing
- An addition of approximately 410 gigatons of human CO2 emissions
Conclusions, based on the most accurate global empirical evidence, satellite measurements:
1. Prior to mother nature's Super El Niño phenomenon, Earth was not experiencing rapid, dangerous and accelerating global warming - no tipping point/runaway temperatures
2. Subsequent to the complete collapse of the Super El Niño phenomenon, the globe has not experienced rapid, dangerous and accelerating global warming - no tipping point/runaway temperatures
3. Despite, on average, a 30% monthly increase in human CO2 emissions subsequent to the Super El Niño, the global warming trend decelerated to a per century trend some 70% less than that prior to the El Niño event.
4. Obviously, CO2 emissions do not function/perform as the claimed global temperature thermostat nor a "control knob"
5. Despite human CO2 emissions increasing since the Super El Niño, the range of temperature anomaly variation has decreased (climate exhibits greater temperature stability)
6. After the Super El Niño, global temperatures achieved a new plateau (see simple anomaly averages - the dashed pink lines), which current monthly variability now appears to oscillate around.
Finally, when a similar analysis is done on both the land and sea surface datasets separately, essentially the same conclusions can be drawn.
