How James Hansen And Michael Mann Destroyed Climate Science

Written by Tony Heller

Climate scientists used to understand that the sun controlled Earth’s climate – until Michael Mann and James Hansen destroyed the temperature record about 20 years ago. Total solar irradiance (TSI) has increased since the Little Ice Age.

The graph below is from the 1990 IPCC report, and it shows temperatures were much warmer 900 years ago and were much cooler 400 years ago during the Little Ice Age.


If we overlay the TSI graph and the 1990 IPCC graph, we see the correlation between temperature and TSI.

The 1990 IPCC graph is hand drawn and the X-axis is irregular. A small shift and scaling change lines up TSI and temperature almost perfectly.

Similarly, we see a correlation between the 1974 NCAR global temperature graph and sunspots.

Again, a small shift of the hand-drawn 1974 graph causes sunspots and temperature to line up very closely.

TSI and Sunspots are only part of the solar climate story.  Comets have two tails because there are at least two distinct types of energy being emitted from the Sun – photons and ionized particles known as the Solar Wind.

The Earth’s magnetic field protects us from the Solar Wind – directing the charged particles towards the poles where they release energy as the Northern and Southern lights.

Without the magnetic field surrounding Earth, our planet would be unlivable.

In 1859, a large solar storm brought charged particles across the entire planet, with so much energy that people all over the world could read at night, and telegraph lines carried current without any power supply.

The storm came from a coronal mass ejection which was released from this sunspot group.

The solar wind brings a lot of very variable energy into Earth’s atmosphere, which is completely unaccounted for by climate scientists.

And because the Earth’s and Sun’s magnetic fields are constantly changing, this causes weather patterns on earth to change too – leading to all sorts of superstitions like the current “climate change” cult.

The correlation between solar activity and Earth’s temperature was obvious until 20 years ago when Michael Mann and James Hansen corrupted Earth’s temperature record through massive data tampering.

Mann made the Medieval Warm Period and Little Ice Age disappear with his hockey stick graph.

Meanwhile, Hansen made the 1940’s warmth and subsequent cooling disappear.

There was no question at the time that the 1930s and 1940s were very warm, and that the temperatures correlated with solar activity.

In 1951, MIT professor Hurd C. Willett correctly predicted 20 years of global cooling, based on sunspot cycles.

The first director of NCAR understood that sun controlled Earth’s climate.

In 1973, Roberts predicted a drought based on sunspot cycles.

By destroying the temperature record, Mann and Hansen wrecked an entire field of science – and caused scientists to pursue a superstitious relationship between temperature and CO2 instead of doing actual research.

    Excellent, Tony.

    When solar activity increases the heliosphere expands and this reduces the cosmic ray intensity reaching the inner Solar System including Earth. There is now compelling evidence that cosmic rays assist cloud formation, and so there are fewer clouds and thus lower albedo when sunspot activity increases. Clearly this leads to warmer temperatures and the opposite occurs when solar activity decreases.

    Magnetic fields from planets may also divert cosmic rays towards or away from Earth and so we do indeed also find some correlation between some of the various superimposed natural climate cycles and planetary orbits.

    But it is important to recognise that the effect of the Sun’s radiation (after variable reflection by clouds) still primarily warms regions up in the troposphere, the solar radiation reaching the surface being way too insufficient to explain the observed temperatures except for a very small portion of the globe where the Sun is almost directly overhead on a clear day. The Venus surface receives only about one-eighth of the direct solar radiation that Earth’s surface receives, so how does it warm by about 5 degrees during four months on the sunlit side compensating for the similar and inevitable cooling on the dark side? Until you can answer that question then, with respect, you really do not understand what is going on on Venus, Earth or any planet.

    The process whereby the new energy each day makes its way from the middle and upper troposphere to the warmer surface is not yet understood by climatologists. Indeed the only place you may find it explained directly from the Second Law of Thermodynamics is in the 2013 paper at and this is a major discovery that provides the correct alternative to the guesswork of Mann and Hansen in regard to backradiation.
