Question 1. What Does Climate Change Mean? [Quorvita]
A. Standard Definition
The various definitions of climate change all include a type of causation clause which connect temperature to a greenhouse effect, based on carbon dioxide released by fossil fuels. A thermometer only measures temperatures and does not measure what causes the temperature. There is no instrument, machine, or device known to mankind that can measure which portion of the temperature is applicable to carbon dioxide (CO2) or a particular CO2 molecule that comes from fossil fuels. This type of causation element is an after-the-fact condition that renders the definition ambiguous.
B. Normal Temperature Fluctuations
Historical temperature measurements show that the normal average temperature anomaly fluctuation is at least ± 2 degrees C (3.6°F). There have been temperature changes that were much higher and lower, but the average fluctuation between warming or cooling trends is about ± 2° C.
C. Average Time to Start/Stop a Trend
A trend is typically a temperature change of 10°C (18°F). A trend has never started or stopped abruptly, even as a foot race does not start or stop immediately. Historically, the average time for a trend to start or stop is between 2 to 20 thousand years. A start or stop period of less than 1000 years could not be found in ice core or fossil sediment records. As such, projections based on a period of less than a thousand years are unsupported. The ocean is a massive heat regulator and has never allowed the Earth’s temperature to change suddenly, even when struck by massive meteorites. Short term time periods are not supported in the 580 million years of temperature records.
D. Normal Carbon Dioxide Levels
Many in the media have voiced concern that CO2 levels are too high. But, is that true? The average CO2 level over the last 580 million years is 2560 ppmv with a standard deviation (normal fluctuation) of 2057 ppmv. The current level (red line) indicates that Earth is currently at a dangerously low CO2 level. Plants breathe CO2. And lab tests confirm that plants die when the level drops below 100 ppmv CO2. The graph displays actual data.
ANSWER TO QUESTION 1. [Quorvita]
Definitions containing “after-the-fact” conditions are not appropriate. It is better to use an objective, verifiable description such as “Global Warming “or “Global Cooling” with relevant criteria, such as where the average temperature has increased/decreased in excess of the normal historical fluctuations. This information would have to be compiled for a meaningful period of time, such as a thousand years. “Global Stable” could define periods between warming and cooling events.
