Finnish study finds ‘practically no’ evidence for man-made climate change

Study Finds Link Between Pollution and Suicide
A new study conducted by a Finnish research team has found little evidence to support the idea of man-made climate change. The results of the study were soon corroborated by researchers in Japan.

In a paper published late last month, entitled ‘No experimental evidence for the significant anthropogenic climate change’, a team of scientists at Turku University in Finland determined that current climate models fail to take into account the effects of cloud coverage on global temperatures, causing them to overestimate the impact of human-generated greenhouse gasses.

Models used by official bodies such as the Intergovernmental Panel on Climate Change (IPCC) “cannot compute correctly the natural component included in the observed global temperature,” the study said, adding that “a strong negative feedback of the clouds is missing” in the models.

Adjusting for the cloud coverage factor and accounting for greenhouse gas emissions, the researchers found that mankind is simply not having much of an effect on the Earth’s temperature.

If we pay attention to the fact that only a small part of the increased CO2 concentration is anthropogenic, we have to recognize that the anthropogenic climate change does not exist in practice.

The study’s authors make a hard distinction between the type of model favored by climate scientists at the IPCC and genuine evidence, stating “We do not consider computational results as experimental evidence,” noting that the models often yield contradictory conclusions.

The results sharply cut against claims put forward by many environmentalists, including US lawmakers, who argue not only that climate change is an immediate threat to the planet, but that it is largely a man-made phenomenon. Given the evidence presented in the study, the Finnish team rounded out the paper by concluding “we have practically no anthropogenic climate change,” adding that “the low clouds control mainly the global temperature.”

    “the researchers found that mankind is simply not having much of an effect on the Earth’s temperature.”

    The effect that is being observed is due to man-made structures on the ground, and their effect on temperature is being tempered by cooling carbon dioxide, the same gas that nuclear power reactors use for cooling.

    The IPCC uses phantom cloud data generated by their aerosol models. They predict that cloud cover has actually increased (the opposite is true), therefore there would be cooling if it wasn’t for the powerful CO2.

      “therefore there would be cooling if it wasn’t for the powerful CO2.”

      Carbon dioxide cools the atmosphere, it’s a coolant due to the approximately one-third less heat energy it sustains compared to either nitrogen and oxygen; as a denser molecule, carbon dioxide can only hold less heat energy than that of nitrogen and oxygen.

        Dean,
        CO2 has lower heat capacity than O2 and N2, that means for a fixed given amount of energy, CO2 will get hotter than O2 or N2.

        CO2 is indeed a radiative coolant, but radiation is not the only heat transfer mechanism.

          “CO2 has lower heat capacity than O2 and N2, that means for a fixed given amount of energy, CO2 will get hotter than O2 or N2.”

          Carbon dioxide gets warmer FASTER because it’s approximately one-third the volume of nitrogen and oxygen. Carbon Dioxide takes less heat energy to obtain, let’s say, a temperature of 70 F. Nitrogen and oxygen have relatively high heat capacities due to the longer time lapse it takes to saturate their larger volumes with heat energy.

            CO2 has less volume than O2? Interesting. I would have thought that extra C would take up more volume. How is that possible?

            Hi Dean,
            Gases are mostly empty space. One of the basic tenets of science is that at the same temperature and pressure there will be the same number of molecules in equal volumes. 22.4 liters of a gas will contain 1 mole of the gas regardless of its molecular weight.

    With all of our telescopes, satellites, and surface rovers, we must have comparable surfacing temps for the Moon, Mars, Ceres, etc. why is this not being reported??
