It is a Real Red HerringYuroc
Global Warming is clearly a documentable and potentially catastrophic feature of the Earth at this time. However, a careful examination of the best evidence suggests strongly that this warming is coming from the Sun more than it is from human-generated Carbon Dioxide. Warming trends on other planets in our solar system cannot be explained by Earth-generated Carbon Dioxide. Our scarce resources would be better applied to significant aspects of human impact on Earth that we have a good chance of affecting.
Global Warming is clearly a documentable and potentially catastrophic feature of the Earth at this time. As seen in this 300-year-long chart of Earth temperature, prepared by the best scientists in a reputable paper with 132 current scientific references, we are on a warming trend, but within the context of the past three millenia, we are not yet warmer than we have often been.
However, a careful examination of the best evidence suggests strongly that this warming trend is unlikel;y to be caused by Carbon Dioxide increase in the atmosphere because historically the rise in temperature preceded the rise in atmospheric Carbon Dioxide:
So what could be causing global warming? Careful examination of the best evidence shows that Earth temperatures are almost exactly correlated with solar activity. There is a close correlation between solar activity and temperature and none between hydrocarbon use and temperature.:
The final nail in the coffin of the Human-induced global warming position is the discovery that our sister planetary bodies are also experiencing warming trends, which human-generated Carbon Dioxide could have zero effect upon. The observed variation in solar activity is typical of stars close in size and age to the Sun. The current warming trends on Mars, Jupiter, Neptune, Neptune's moon Triton, and even Pluto probably result from similar relations to the Sun and its activity – like those that are warming the Earth.
Hydrocarbon use and atmospheric Carbon Dioxide do not correlate with the observed temperatures. Solar activity correlates quite well. Correlation does not prove causality, but non-correlation proves non-causality. Human hydrocarbon use is not measurably warming the Earth. Moreover, there is a robust theoretical and empirical model for solar warming and cooling of the Earth.
NOTE: It is imperative that the following reasoning NOT be allowed to erupt like a fungus from this new knowledge: If humans are not responsible for global warming, then we have no responsibility to minimize our impact upon the Earth. This is tragically wrong.
Humans are impacting the Earth in a terrible way. Scientists say wildlife extinction rates are soaring. The die-off, they claim, threatens the planet's web of life or biodiversity which sustains farming, forestry and oceans. Rainforests once covered 14% of the Earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. Scientific research shows that in 2003, 29% of open sea fisheries were in a state of collapse:
Bigger vessels, better nets, and new technology for spotting fish are not bringing the world's fleets bigger returns -- in fact, the global catch fell by 13% between 1994 and 2003. Historical records from coastal zones in North America, Europe and Australia also show declining yields, in step with declining species diversity; these are yields not just of fish, but of other kinds of seafood too. Zones of biodiversity loss also tended to see more beach closures, more blooms of potentially harmful algae, and more coastal flooding.
Human impact on the Earth is the issue, not human generation of Carbon Dioxide. Chasing after a reduction of Carbon Dioxide is quite likely to result in a major waste of resources to no effect. Please talk to your elected representatives about reducing the real human impact upon the Earth rather than the phantom human impact from Carbon Dioxide.
