Natural climate variability over recent geological time is greater than reasonable estimates of potential human-induced greenhouse gas changes. Because no tool is available to test the supposition of human-induced climate change and the range of natural variability is so great, there is no discernible human influence on global climate at this time. Perhaps, but there may be other, more scientific reasons. As Peter Sciaky, a retired geologist, writes:
Which is what can be seen in the NASA solar irradiance measurements. These two chart pairs from pages 5 and 7 of the above report show that solar irradiance is not responsible for the sharp increase in observed world temperatures over the last few decades.
In the second pair of graphs, the sunspot cycle has been subtracted out and temperature data has been smoothed. The red line in the irradiance chart shows the resultant best fit while the other lines reflect various damping factors. As shown in the charts, not only have temperatures continued to rise sincethe rate of temperature increase is accelerating.
Total solar irradiance total solar radiated energy has slightly decreased during this period. The report also examines sunspot counts, length of the sunspot cycle, solar magnetic flux, and cosmic rays as part of the study.
A quote from http: The low activity in sunspots from to is of interest. This dip in sunspot activity is called the Maunder Minimum in honor of astronomer E. This is not what we observe in the temperature records. Thus sunspots are not the cause of the sharp global warming we have seen in the last few decades.
The chart above from http: The Maunder Minimum does coincide with the lowest temperature readings, but it is a loose fit at best, and may be coincidental. Of note, the Medieval Warm Period was not as warm as current temperatures. This refutes the graphic shown in the pseudo-documentary which claims the Medieval Warm Period was warmer than present temperatures.
A major research work that was published in has again reconfirmed the original work by Michael Mann. The graph shown in the pseudo-documentary is not based on accurate data.
This assertion is refuted by the following article published by the American Geophysical Union. The assertion in the pseudo-documentary may well be based on this discredited cosmic ray hypothesis.
If you want to look at cosmic ray measurements for the last 50 years, you can see the actual data at ftp: The solar wind is stronger during periods of high sunspot activity which in turn reduces the number of cosmic rays that can reach the earth.
Thus there is an year inverse correlation with the sunspot cycle. Data is from the above web link. The exact quote from the pseudo-documentary is: The following quote is from the U.
This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year 30 billion tons [ Marland, et al.
Human activities release more than times the amount of CO2 emitted by volcanoes--the equivalent of more than 8, additional volcanoes like Kilauea Kilauea emits about 3.
Stratospheric Aerosol concentrations from volcanic eruptions. As per usual, the Global Warming Deniers lie about reality. The eruption of Mt. Helens caused barely a minor bump in aerosols.
The following are statements by Carl Wunsch, professor of physical oceanography at the Massachusetts Institute of Technology and are posted at: He says his comments in the film were taken out of context and that he would not have agreed to take part if he had known it would argue that man-made global warming was not a serious threat.
My views were distorted by the context in which they placed them. I was misled as to what it was going to be about. I was told about six months ago that this was to be a programme about how complicated it is to understand what is going on. If they had told me even the title of the programme, I would have absolutely refused to be on it.

EVERY (6 pound) gallon of gasoline or diesel burned adds pounds of CO 2 to the Earth's atmosphere note 1, essentially alphabetnyc.com have been doing such things for years. People are confused by the fact that only very minimal average temperature rises have been detected, and so they claim that no Global Warming is occurring.
Since the slowdown in surface warming over the last 15 years has been a popular topic recently, I thought I would show results for the lower tropospheric temperature (LT) compared to climate models calculated over the same atmospheric layers the satellites sense.
There’s a lot of information about global warming out there, and conflicting sources can make you think a variety of things.
Various websites, periodicals, and books can offer completely different global warming alphabetnyc.com following list is a compilation of 10 scary global warming fast facts that will truly amaze and astound you.. Alarming Facts About Global Warming. What is Global Warming? Global warming is the slow increase in the average temperature of the earth’s atmosphere because an increased amount of the energy (heat) striking the earth from the sun is being trapped in the atmosphere and not radiated out into space..
The earth’s atmosphere has always acted like a greenhouse to capture the sun’s heat, ensuring that the earth has enjoyed.
* Global warming is defined by the American Heritage Dictionary of Science as “an increase in the average temperature of the Earth’s atmosphere,” either by “human industry and agriculture” or by natural causes like the Earth has “experienced numerous” times “through its history.”.
