The current period of global warming began at the peak of the last ice age approximately 12,000 years ago, a trend that has not abated. The vast majority of the polar ice caps have melted long before humans began using fossil fuels. Clearly, global warming has neither been triggered by human activity nor perpetuated by human activity, the trend is not ours. I am sad that there are those in science and politics who use global warming and the ignorance of the electorate to divert massive sums of tax dollars into this none sense. We have so many real problems that are being squeezed out of funding due to this massive abuse of the public trust and treasure.
