Thanks for a response with substance. Really, i too support reef conservation. But i hate scare tactics from anybody.
Its is not as simple as CO2. There have been periods of higher CO2 levels and life thrived. h2O vapor is a better green house warming gas. There are holes in the theory. Its 1 possible THEORY, like evolution, like the bohr atom model, like thermodynamics. Theories are supported by facts, they are not truth in themselves. The IPCC kicked out some very leading scientists who questioned their use of the theories to support facts to support the scientific method & not the other way around.
Our military has supported alternative fuel use for STRATEGIC ENERGY interests, so that if we get into a prolonged global conflict we still have energy for our machinery. It is misleading to say they did it because they are green.
The only thing constant in nature is CHANGE. I would like future generations to have a nice earth too, but stay scientific and quit with the scare tactics. There are many ways to look at this. It is also an energy issue. Energy has allowed us to power tools, including the pumps & lights of your reef tank. Most other sources like ethanol, solar, wind, thermal do not pack as much of a punch as fossil fuels, environmentalists hate nuclear which is the next best. So if we get scared by them to cut down our energy use & lifestyle, whats left? Do western countries like the US, UK & germany who have enjoyed the advances of high energy & have been polluting the earth for hundreads of years, suddenly tell the rest of the devolping world we were wrong, and they shouldnt advance to our lifestyle because we are more enlightened now? So it is extremely geopolitical. To deny that is as silly as it is to say a theory is fact.
It is CO2 plain and simple. And we're doing it. That's the fact of the matter. The only real political motivation is coming from those who will lose big if we shift over from fossil fuels. Germany, China, Japan and many other countries get the threat global warming poses to us all. They are dumping coal fast. And, Germany is a very conservative government. And, well China is China. The facts are not political. But the main "other theories" are coming from Mobil and the Koch brothers. The oil companies will lose profits if we shift.
Other facts are the Maldives, Indonesia, Marshall Islands, the GBR, Hawaii and our coasts are threatened (Louisiana is sinking/eroding visibly). The scientific study about Hawaii was paid for by the tourism board hardly a "political" group. The governments of the Marshall Islands, Maldives and other island nations are petitioning the UN calling for action so their nations don't disappear. Literally drown. Our military is switching to renewables. Even the Bush administration set up a DoD study group in 2007 to assess the national security threat global warming poses to our country.
Sorry for the rant but we should be passionate about this given what our hobby is.
