- This entry gets a little more detailed than I normally do, but in the last week I've been having extensive discussions with some individuals that are concerned with CO2 emissions causing the eminent demise of our planet. Seemed to me that replicating the work to my blog would make a good article... for those that aren't interested in "spin" -- but in the truth.
After you look at this small amount of evidence, and before you go explaining it to "lousy Larry" on the street, just remember what Terence said:
- "Hoc tempore obsequium amicos, veritas odium parit":
(In these days friends are won through flattery, the truth gives birth to hate.)
The first is the CDIAC's estimate of CO2 emissions and the second is NASA's recorded climatological records.
I got this CDIAC graph from EarthPolicy.org. It shows the increase in total CO2 emissions from 1751 to the present (prior to 1825 the amounts were too small to graph):
This NASA graph shows the difference of the yearly US temperature averages (0 degrees C being the mean of the last 128 years) -- from when they were first recorded (in 1880) to the present:
Looking at the two graphs, I see several things:
1) Since the early 1880s, CO2 emissions have increased astronomically.
2) The largest difference in minimum and maximum yearly temperature means for any 5 year period falls between 1917 (low of -1.071) & 1921 (high of +1.119). (A total difference of 2.226 degrees C.)
3) The highest single yearly average mean is actually a tie between 2 years: 1934 & 1998 (+1.238).
4) 1934 had ~1.125 billion tons of CO2 emissions; 1998 had ~6.875 billion. (A difference of ~5.75 billion tons.)
5) The difference in the absolute lowest recorded yearly mean temperature (1917: -1.071 degrees C) and the highest recorded yearly mean (the 2 years listed in #3 & #4) is about 2 degrees C (2.309524).
6) The total change from the first 5 year mean ~(-0.24) to the most recent ~(+0.64) is a difference of almost 1 degree C ~(0.880952).
7) The very first recorded five year mean temperature (1882) is identical to the five year mean temperature recorded in 1977.
8) The last year on the temperature graph -- 2008 -- has an annual mean temperature identical to that recorded in 1890.
9) The estimated yearly output of CO2 emissions in 1890 was ~0.375 billion tons, in 2008 was ~8.375 billion tons. (A difference of ~8 billion tons.)
10) There is only one yearly mean that falls more than 1 degree lower than the 128 year average: 1917, but there are 5 yearly means that fall more than 1 degree above the 128 year average: 1921, 1931, 1934, 1998, & 2006.
(Incidentally, 3 of those 5 occur well before the beginning of the explosion of CO2 emissions that started in the 1950s and have continued since).
There is no observable correlation in the data between the graph of CO2 emissions and the graph of yearly temperature means.
This is only ONE comparative example of MUCH data that I've sifted through. After extensive digging, I have yet to find even one piece of recorded scientific evidence that reflects a direct tie-in to CO2 emissions and climate.
Therefore, it's apparent to me (based on the last 128 years of recorded global temperature change) that the urgency of reducing CO2 emissions to "save the planet" from catastrophic climate change is an unmitigated hoax.
