Natural Cycles Affect Climate

Natural weather cycles have been hypothesized and even shown in certain cases to be contributors affecting the Earth's complex climate. These range from the recent theory that variation in the sun's radiation has provided the basis for Earth's very climate to the cycles exhibited by El NiƱo and Atlantic hurricanes.

There is consensus among NOAA hurricane researchers and forecasters that recent increases in hurricane activity are primarily the result of natural fluctuations in the tropical climate system known as the tropical multi-decadal signal. The tropical climate patterns now favoring very active hurricane seasons are similar to those seen in the late 1920s to the late 1960s. The current active hurricane era began in 1995, meaning the nation is now 11 years into an active era that could easily last several decades (20-30 years or even longer). We can expect ongoing high levels of hurricane activity — and very importantly high levels of hurricane landfalls — as long as the active era continues.
Along the same lines, researchers have found a connection between Northern and Southern Atlantic Ocean circulation and a natural "seesaw" pattern of climate.
After the end of the last Glacial both Hemispheres became warmer as a result of melting ice sheets, but during the last 9000 years we can identify a persistent "seesaw" pattern. When the South Atlantic was warm it was cold in the North Atlantic and vice versa.


Our results from Nightingale Island in the Tristan da Cunha island group, between South Africa and Argentina, for the first time give evidence of warming of the South Atlantic associated with cooling in the north. This is a major breakthrough in palaeoclimate research.
Given the preponderance of these natural cycles being shown to affect localized areas around the globe, isn't it about time for a real look at other theories that ignore this fact. Of course I'm talking about the anthropogenic climate change theory caused by increased in carbon dioxide emissions. Even though carbon dioxide is only a small contributor to whole of greenhouse gases politicians have focused on this molecule. Why is that? Probably because water vapor (the most abundant greenhouse gas) is something that can't be controlled and nobody is going to listen to a politician calling for the explicit destruction of civilization. The solution: damn carbon dioxide since we expel it anyway, we don't need it say the politicians.

The problem is that you're not going to get a fair discussion on climate science while politicians are writing the checks in government, i.e., all means of scientific inquiry are open to free individuals and not subject to political pull or censorship. When science is not directed by the pursuit of independent minds but rather by wetting one's finger and checking the political air for the best wave of support you can be sure that all will suffer the consequences. Just as government shouldn't fund public media it shouldn't be funding science either.
