Let's put some toll booths out near Venus to collect the taxes.
Ed, no one denies the effect of the Sun's effect on Earth's climate. In fact James Lovelock who coined the term Gaia yrs. ago to describe the Earth as a living organism says that the increased activity of the Sun and consequent warming of the Earth coincides with the increased CO2 in the atmosphere. This results in the trapping of more of the increased incoming energy from the Sun. Without the increased human produced CO2 Earth would be effected more slowly by the greater solar activity. As it is we are seeing a more rapid warming than in previous solar maximums. Since man is a natural part of the ecosystem this increased CO2 is a natural phenomena but never the less it can be highly toxic to the atmosphere. That is the kind of effect a big brain can have on a planet. But the big brain can also recognize when its natural effects on the environment need to be modified. If the industrial age had by coincidence not coincided with a solar maximum we would likely be seeing a more gradual warming of the Earth and therefore adaptation by all the Earth's lifeforms. That species adaptation would happen as it always has even though there have been 5 great extinctions, one by asteroid, 4 by release of excess amounts of methane from permafrost and the present 6th extinction by big brain activity which is leading to excessive CO2 release and resulting melting of permafrost and subsequent methane release.
