Increased solar activity is obvious - especially for a the minumum side
of the cycle. These changes are not unusual over long periods of time.

Mars polar ice has shrunken, both north and south poles. I do not trust
my observations much, but even I, with over 50 years of observing Mars,
see a lack of polar ice with my small scopes.

Even further out planets show some differences from some years back.

I do not deny that humans cause some problems, think of all the CO2 (and
methane) we and our cows exhale, our burning of coal (instead of
uranium), and intentiional damage like buring of oil wells by Saddam.
Nautral causes: volcanos and biology etc.

The naysayers dwell mostly on US excesses, yet polution is horrendous in
other parts of world, so their noise should be treated as political
nonsense. Some of their criticism is valid, but when these same people
are agianst wind energy (Kennedy: it disturbs their view), or their
fight against nuclear energy (lesser of an evil), they show their
infantile grasp of reality and their wish to return to the stone age
(except for their love of SUVs and private jets (again, Kennedy).

Note that I am a conservationist who planted many trees and use very
little energy for light, heat, a/c, travel.
