Instead, producer Martin Durkin points the finger squarely at
natural changes in the sun.
The observed pattern is not consistent with purely
natural changes in the Sun's energy output, volcanic activity, or natural climate variations such as El Niño and La Niña.

Each new harvest brings us into balance with the

changes in the
natural world and

But the U.N. panel said
natural causes, including
changes in the
sun's output, may have been a significant factor before then.
Several
natural causes were tested with the model, including volcano eruptions and
changes in the
sun's radiation.
Of course, while short - term
changes in sea level can be predicted fairly accurately based on the motions of the moon and
sun, it is a lot harder predicting the ups and downs of the average global surface temperature — there is a lot of noise, or
natural variation,
in the system.
Natural factors contributing to past climate
change are well documented and include
changes in atmospheric chemistry, ocean circulation patterns, solar radiation intensity, snow and ice cover, Earth's orbital cycle around the
sun, continental position, and volcanic eruptions.

Another prominent source of
natural variability
in the Earth's energy imbalance is
changes in the
sun itself, seen most clearly as the sunspot cycle.
Changes in weather patterns, the eruption of volcanos, changes in ultraviolet output of the sun linked to the 10 - 11 year solar cycle and other natural phenomena can, like CFCs, inhibit the production of ozone.

The present round of rising temperatures do not track
natural cycles of the Earth, volcanic activity, or
changes in energy from the
Sun.
There is also the coincidence problem that since the rotation of the Earth
changes over time [it slows down] we live
in the special period where the
natural cycles just happen to match that of the
Sun.
Looking at all of the various inputs to global climate - including CO2 and SO2 emissions from man, and
natural cycles like La Nina / El Nino, as well as
changes in the
sun - they believe that the rising sulfate emissions is the most likely factor to have cause the global warming slowdown, between 1998 and 2008.
The authors say this «slowdown» was caused by a combination of
natural ocean cycles, volcanoes going off, less energy coming from the
sun and
changes in the amounts of tiny particles
in the atmosphere, mainly from industrial pollution.
Natural variations
in climate include the effects of cycles such as El Niño, La Niña and other ocean cycles; the 11 - year sunspot cycle and other
changes in energy from the
sun; and the effects of volcanic eruptions.
The climate has
changed many times
in the geologic past due to
natural causes — including volcanic activity,
changes in the
sun's intensity, fluctuations
in Earth's orbit, and other factors — but none of these can account for the current rise
in global temperatures.

Thermometers dropped deep
in the ocean and
in holes bored
in permafrost show warming patterns that do not match up with
natural influences like
changes in the
sun's brightness.
Natural factors such as the
Sun (84 papers), multi-decadal oceanic - atmospheric oscillations such as the NAO, AMO / PDO, ENSO (31 papers), decadal - scale cloud cover variations, and internal variability
in general have exerted a significant influence on weather and climate
changes during both the past and present.
First, the climate
changes which we have witnessed
in the past have been mainly the result of
natural factors,
changes in the Earth's orbit or
in the amount of radiation given off by the
Sun, for instance — Man's activities had only a small part to play.
The warming since 1850 has always been due to known external forcing (the
sun) modified by known internal forcing (some big volcanoes, a Siberian meteorite and a minor CO2 rise) and to unknown internal forcing (mainly cloud formation and albedo
changes, perhaps some particulates
in the air) otherwise known as
natural variation.
Natural Variability Doesn't Account for Observed Temperature Increase
In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188

Even Prof Jones admitted that he and his colleagues did not understand the impact of «
natural variability» — factors such as long - term ocean temperature cycles and
changes in the output of the
sun.
The downturn
in temperature since the 1940s, whether due to a variation
in the
Sun's radiation or some other
natural cause, could indeed
change to a
natural upturn that would add to greenhouse warming instead of subtracting from it.
Such is the complexity of rainfall patterns that
changes can be caused both by human factors, such as greenhouse gas emissions and atmospheric pollutants, and
natural factors, such as
changes in the
sun's activity and explosive volcanic eruptions.
Yes, it is 2011, soon to be 2012, and the Dinosaurs, the most successful species to ever populate the earth (for approximately five hundred million years) were not extinguished due to their inability to evolve and grow with
natural changing conditions, but were simply eliminated by a one -
in - a-million extra-terrestrial event over a short period of time (one to three years), as were all forms of
sun reliant life with the exception of a few ocean dwelling species, subsurface ground dwelling worms, plant life like lichens and other mindless species able to lie dormant for extended periods of time, as well as nocturnal, ground dwelling little rodents that ate roots, dead or alive, (from which we so - called superior life forms evolved).
