Ten variables that can cause climate change

Global Warming, 

or Climate Change, 

is a divisive 

political issue, 

often science-free.

It has been 

highjacked

by politicians, 

environmental 

pressure groups, 

and other leftists.

Earth's climate is always changing. 

‘Climate’ is defined as average 

weather over a 30-year interval.

The difference between the 

annual average temperature ,

and its 30- year average, 

is the the temperature anomaly.

The measurements 

are not evenly distributed 

over the globe, especially

over the oceans, and 

at high latitudes.

Questionable schemes are used 

to extrapolate (or fill in) sparse data 

to approximate global coverage.

Filling in data is making up data.

For land surfaces, there are more

filled in numbers than actual 

temperature measurements.

The following variables 

influence Earth's climate:

1) 
Earth orbital and orientation variations 

2) 
Natural changes in ocean circulation, 

      ENSO (el Nino) and others 

3) 
Solar irradiance and activity 

4) 
Volcanic aerosol emissions 

5) 
Greenhouse gas emissions 

6) 
Land use changes & economic growth

(cities, logging, crops, grazing ...) 

7) 
Regional differences 

8) 
Stochastic variations of a 

      complex, non-linear system 

9) 
Unpredictable catastrophes

10) 
Measurement error, and warming bias

-- the people who predict serious warming

also own the historical temperature record,

and they want their predictions to come true !

The variables above are not all independent.
