So, Mars is warming too:
Simultaneous warming on Earth and Mars suggests that our planet’s recent climate changes have a natural—and not a human- induced—cause, according to one scientist’s controversial theory.
Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.
Mars, too, appears to be enjoying more mild and balmy temperatures.
Wow, our carbon emissions sure do have some reach.
Instapundit makes a good point:
Right or not, this doesn’t matter to me — as I’ve noted before, I think we should be trying to minimize our burning of fossil fuels for lots of other reasons. But it does suggest that people should be wary of getting too far ahead of the science. And if this explanation turns out to be correct, overselling global warming could lead to a backlash in which efforts to reduce pollution lose credibility, which would be bad as we should be reducing pollution regardless of global warming.
