From the latest issue of Science News:

Scientist have tested 70 year old whale oil from the Charles W. Morgan of
Mystic, CT.

They found PCB's and similar chemicals.

What is striking is that they concluded these chemicals are naturally
occuring since man did not yet begin producing them 70 years ago.

Once again, man is not the culprit!

In the same issue:

It appears that Global Warming is occuring on Mars. Evidence of rapid
climate fluctuations have been observed by the Mars Reconaissance Orbiter
(MRO) satellite.

Scientists claim man is not responsible for the warming on Mars and they are
using the data to correlate climate change on the earth.

The sun, cosmic rays and space environment is what the Earth and Mars share
in common.

Environmentalists counter that man produced greenhouse gases are escaping
the earth and surrounding Mars. They also claim that some of the greenhouse
gases in their transit toward Mars entered wormholes, traveled back in time
and caused the global warming seen on earth millions of years in the past
before man even existed.
