The lie is that man is responsible for it. Those amounts are nothing compared to the heat active volcanoes pour into the atmosphere. Our earth cools and heats. There was a northwest passage, and then there wasn't, and then there was. There was an age of ice, and an age of receding ice. The money making gimmick was to blame it on us and then tax and spend us to death.
Mankind
IS responsible for it, you flaming retard.
The amount of heat given off by volcanoes is utterly insignificant compared to the amount of energy the Earth receives every minute from the sun. Moreover, you ignorant rightwingnutjob, volcanic activity has not increased at all over the last two centuries compared to the previous 5000 years in which the Earth was slowly cooling.
There has never been a "
northwest passage" open to shipping in all of human history. You're full of idiotic denier cult myths (as well as enormous amounts of bullshit).
There was an "ice age" that lasted almost 100,000 years and ended about 12,000 years ago, moron. Scientists are clear on the reasons why the "ice age" occurred and the reasons why it ended. The ice stopped "receding" from that "ice age" over ten thousand years ago, and then about five thousand years ago the Earth started slowly cooling. Until a century or so ago when mankind's carbon emissions began to upset an atmospheric balance of CO2 that had naturally stayed under 300ppm for millions of years, and started an abrupt warming trend. Now CO2 levels are over 400ppm. Scientists have determined that the last time CO2 levels were this high, and were sustained at this level for awhile, was 15 million years ago when temperatures were 5 to 10 degrees hotter than present and sea levels were 70 to 120 feet higher than they are now. Meanwhile mankind is busily still increasing atmospheric CO2 levels which may wind up doubling (or more) the old pre-industrial CO2 levels of 280ppm.
