Never.
Those who are all worked up about the so-called climate-gate scandal are forgetting that ALL pollution is bad. Or perhaps that is something they want us to forget.
1. No scientist disputes that there are natural warming cycles to climate.
2. No scientist disputes that the pollution caused by greenhouse gas emissions contribute to the warming effect of the earth.
These conclusions are well-documented by many independent data sets and were reached by the scientific community at least 10 years before the alleged “cooking” of the data by the team at the University of East Anglia led by Dr. Phil Jones.
The climate-gate thesis that the global community of over 10,000 informed and independently minded scientists have all been bullied by some conspiracy led by either Dr. Jones at East Anglia. or by Dr. Michael Mann at Pennsylvania State University defies common sense.
It is only in the past 4 years that climate scientists have additionally concluded that:
3. Human greenhouse gas emissions have become the dominant cause of climate change and
4. If we don’t do something about it soon, these changes will become irreversible and goodbye to climate cycles.
These recent conclusions are based on independent data collected by NASA, NOAA, and many other researchers around the world. The unlikely possibility that the data managed by Phil Jone’s team has been manipulated to agree with these other sources does not change their conclusions.
Nor does it make it good to pollute. Pollution disrupts the natural cycles by accelerating the effect of warming. All pollution is bad and it is no surprise that it is caused by irresponsible human activity.
