Land-based temperature monitoring devises are predominantly clustered in urban areas, which generate higher temperatures because of the heat produced from congestion, concrete, and asphalt. Temperature data from satellites, weather balloons, and rural monitoring devices reflect temperatures that have risen only very slightly over the last century or so (except for the 1930s and early 1940s, which were very hot and dry in comparison).
Atmospheric carbon dioxide is a trace element -- currently about 420 ppm, or about 0.04 percent of the atmosphere. Fifty million years ago CO2 levels were around 7000 ppm, when the earth had an overabundance of vegetation and biodiversity. CO2 levels in the thousands were not unusual in the intervals between glacial expansion. Twenty thousand years ago, at the height of the Holocene glacial maximum, CO2 levels dropped to 180 ppm. Had it dropped to 150 ppm, scientists assert that there would not have been enough CO2 to sustain plant life.
Current scientific consensus asserts that carbon-dioxide levels affect temperature. If that were true, then increases in CO2 would result in higher temperatures. Ice cores have verified that temperatures rise first, followed by rising CO2 levels a century or two later. As temperatures go down, CO2 levels subsequently drop. The opposite would happen if CO2 controlled the temperature, but it never happens that way. Industrial CO2 levels began to rise in earnest in the early 1940s, but as CO2 levels continued to increase during the 1940s, temperatures dropped. Global temperatures have not risen nearly as fast as predicted by the climate gurus.
The most compelling graphical display that correlates variations between temperature and an outside influence is between temperature fluctuation and solar activity. The number and intensity of sunspots and solar flares convincingly track changes in the earth’s temperature.
Since the Ice Age scare during the 1970s, graphs have shown that when the average temperature has gone up a bit, it’s because the winters have become slightly milder. But the higher average summer temperatures have remained unchanged. As for greenhouse effects, water vapor from clouds accounts for hundreds of times more greenhouse effects than atmospheric CO2.

The scientists interviewed in the movie all state that when you apply for any grant to research any problem, you must mention something about climate to get approved. The bigger the threat posed by the problem, the more money you can get. If you’re paid to defend climate change, then by God you will defend climate change.

I saw Climate: The Movie and thought it was pretty good.

And everything in this article is spot on.

Our Modern Warm Period is just another warm period within Holocene Glacial Period.

And even that is a cycle within many glacial cycles of the current ice age.

And even our current ice age is one of many ice ages.

So we're talking about cycles within cycles. None of which are caused by folks driving pickup trucks.

Fortunately....last year globally more coal was burned than any year before in recorded history.

Hopefully that is keeping enough carbon in the atmosphere that we can keep the planet from falling into an ice age.....no matter how much the death cultists capture.

Why don’t we look at climate data for say, the last 15,000 years? Since the end of the last ice age. I don’t have that data and neither do the ‘experts’. I would bet there have been
some very large temperature fluctuations and rain fall amounts through the centuries.

CO2 based scam is all it is.
