Global Warming On Mars

Q: Seems Mars is going through A warming trend too. Just more evidence that global warming is a natural event. I mean set aside the evidence that the earth goes through temp changes cyclicly, long before mankind ever discovered fossil fuels, but now we have another planet in which there is evidence of weather changing. Since the Mars rovers were not built as Hummers, the Enviro-Nazis would be hard pressed to blame Humans or Fossil fuels for this happening. I guess that means they will ignore it as they do everything else that contridicts what they want to "prove".

A: So what's your theory for what would happen if you dumped 22 billion tons of extra CO2 into Earth's atmosphere each year?

Just because the Mars might be having climate change of unspecified magnitude doesn't mean it's related to Earth's. It's possible that it is, but even if so, the only possible connection, variation in solar output, has already been found to contribute no more than 10% to the current rapid warming trend.

Like you, scientists know that cyclical and non-cyclical climate changes are common on Earth. And also like you, scientists are hypercritical of each other. They are the first to pounce on colleagues who make mistakes, and especially those who make wild ass theories.

So why are scientists so much in agreement about anthropogenic climate change? It's because instead of being the kind of smooth variation you expect from natural causes, there's been an abrupt spike in warming. Eliminating all other possible causes, there's still something left over, a big something, and that something correlates almost exactly to the burning of fossil fuel in recent times.

Couple that data with the greenhouse gas theory, which was developed to explain why the Earth is not a huge snowball, and you get the theory of anthropogenic global warming.
