The amount of sea ice has always fluctuated in long term cycles.
We just finished a low ice cycle and may be going into a high ice cycle.
The problem is that the records do not go back very far and its imposable to tell the ice was doing even 100 years ago.
This can be seen in the history of the Northwest Passage.
it was first navigated by Roald Amundsen in 1903–1906
This was after the Franklin's lost expedition was lost due to heavy sea ice in 1845
Reading the history of both expeditions will show that the Franklin expedition was unlucky and got trapped by a period of heavy ice years and the
Amundsen try was lucky and made it because they just happened to try during a period of low ice years.
This can also be seen long term by this chart they the world temperatures have a lot since the ice age started.
The world has been in a increasing period of rapid glacial cycles
And with each of these cycles during the warming part of the cycle the temperatures and CO2 levels have increased.
the were before man could cause the problem.
And now its more likely then not another one of these natural warm cycles and not man caused.
It would not be hard for a researcher to have guessed in the 1980s that we were starting one of these warm cycles and plant the theory that CO2 was
the cause and the tree huggers took it from there.
The biggest problem the tree huggers would have would be to get the laws in that they wanted before the cycle ended and make it look like they had
solved the non-existent problem.
there timing looks to be very close if no one catches on and realises that its just a natural cycle.
By the time people find out this was a natural cycle and the whole country has been taken off high CO2 output it will be to late to restart using coal
How many time have laws on the books been repealed. Its easy to make laws but very hard to repeal them.
This is why many power companies do not want to shutdown there coal fired plants.
Its cheaper in the long run to sequester the CO2 under ground with a add on to there power plants and if this is a natural cycle they are only out the
cost of the add on and not the whole power plant.
This my also be why the tree huggers don't want wind and solar in there back yards. the higher up in the environmental movement know that the cycle
will end and they will be stuck looking out there door and seeing these wind and solar plants once built.
