After his horrible defeat in 1999, Al Gore retooled and created his lecture, "An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do About It".
The idea that 'Global Warming' is a hoax, or a mistake in the data, has been propigated by reactionary wing-nut radio, but I did a little research. I found that the argument is deep, there are large inconsistencies and variations in the limited data we have. After all we've only had satellites flying around the planet since 1951.
The pseudo-scientists and fringe academics who ask questions, sometimes legitimate questions, are real and right to be skeptical. Unfortunately, their curiosity ends as soon as their political and financial interests are met. The deeper story is that, climates are too complex for our limited time on the planet to comprehend, yet we keep polluting, in spite of the growing evidence.
- "Carbon in the atmosphere acts like fertalizer." - True, but it has a half life of just seven years in our atmospher, and is mostly absorbed into the seas, creating carbonic-acid and destroying the shells of microscopic phytoplankton at the base of the food chain.
- "Global Warming is caused by sun spots" - the sun spot cycle went down last 10 years, as temperature increased.
- "The Warming of the planet is a normal variation." - Turns out that the EARTH is actually cooler than it should be because it is shielded by our carbon pollution.
