[Leftism is Mentally Deranged]

There are several cycles that affect climate on the earth. Some of them are:
1. daily. earth spins.
2. yearly. earth goes around the sun
the tilt of the earth changes, producing the seasons.
the earth is at varing distances from the sun as it goes around the sun
3. the various cycles of the sun

there are many factors on earth that affect the amount of heat that the earth retains from the sun, or dissipates the heat into space
Some of them are:
1. surface reflectivity
2. cloud cover
3. CO2 in the air
4. Dust and particles in the air

there are many other factors that affect the earth's temperature and climate. All factors have to be considered.

I doubt that all factors are being considered.

How about more facts? How about a non-political discussion of the facts in the matter?

I think the key element which no one ever talks much about...concerning the earth, the other planets, the Sun, the environment, etc....is magetic variation. Basically...the earth is a bit of a huge steel ball...which rotates...on a slight swirel...ever so slight...just enought to trigger four seasons and cause a airflow that drifts all over the planet. If you took the Sun value of magnetisicm and then ran a model against it...then ran the same test with a 1 percent upswing or downswing...I'm betting its enought to cause heating or cooling. Course, I'm not a rocket scientist...but I doubt seriously that any significant research has been done on this idea.

All factors have to be considered. ... I doubt that all factors are being considered.

In order to do the science effectively, the most significant factors should be the ones that get the most attention. Factors that have a very minor effect are ... minor factors.

At 368 parts per million CO2 is a minor constituent of earth's atmosphere-- less than 4/100ths of 1% of all gases present. Compared to former geologic times, earth's current atmosphere is CO2- impoverished.

Dr. Patrick Michaels has demonstrated this effect is a common problem with ground- based recording stations, many of which originally were located in predominantly rural areas, but over time have suffered background bias due to urban sprawl and the encroachment of concrete and asphalt ( the "urban heat island effect"). The result has been an upward distortion of increases in ground temperature over time(2). Satellite measurements are not limited in this way, and are accurate to within 0.1° C. They are widely recognized by scientists as the most accurate data available. Significantly, global temperature readings from orbiting satellites show no significant warming in the 18 years they have been continuously recording and returning data (1).
