Better search a bit deeper if you believe the tilt, in relationship to the
sun, never varies.

He said, "The axis the earth rotates on is tilted at about 23.5 degrees all
the time."

See the word "about"? (Hint, hint...)

Does that mean the earth scientist that say the northern hemisphere is
warming and the southern hemisphere is cooling because of current
extreme tilt of the earths axis, not because of the activities of man,
do not know what they are taking about?

The axis the earth rotates on is tilted at about 23.5 degrees all the
time. But, because the earth revolves around the sun, the part of the
earth that is tilted towards the sun is the Northern Hemisphere. In the
winter, the Southern Hemisphere is tilted towards the sun. In the spring
and fall, the earth is titled so that both hemisphers get equal amount of
light (on the equinox).

Look at the diagram in this page:

http://en.wikipedia.org/wiki/Earth%27s_seasons

The earth's axis is always tilted in the same direction. But as it
revolves around the sun, because of its tilt and is relative position to
the sun, the northern hemisphere gets more sunlight during the summer in
the north, and less light it winter in the north.

The scientists say that it the earth is warmer than it otherwise would
have been, taking into account different cycles, including the day/night
cycles, the annual seasons, and other cycles, like the sunspot cycles.

following:

This is an example of a theory. A theory is always testable. As it
turned
out, this particular theory was wrong.

As is the theory that human activity is affecting climate.

It may very well be wrong. However, the preponderance of evidence
available supports the theory that man is affecting the global climate.

BTW, man is doing this with more than just greenhouse gases. By
destroying rainforests, man has change the weather in some parts of
south America.
