Hot time on Mars - Updated

The Red Planet is warming up and there aren't any humans there

Here's another of those news stories that keeps repeating.

If the climate is changing on Earth and Mars by about the same miniscule amount, what are the chances that humans are responsible? The Sunday Times covers the story.

Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.

Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.

Do you think that the same thing might be causing the variations on both planets?

Of course the report attributes a different mechanism to Mars warming. But hey, this is just the latest sanitized report.

I linked to two articles back in September of 2005 that talked about the shrinking Martian ice caps. It's the same story, only global warming apologists are making excuses. Here is an 2002 article about sunspot influence on climate that I have cited before.

So either there are two completely different processes causing approximately the same change on two different planets at about the same time, or something that the planets share is influencing both in the same way at the same time.

Which do you think is more likely?

UPDATE - Guess what I found (thanks to no authority). This 2004 article.

Global warming has finally been explained: the Earth is getting hotter because the Sun is burning more brightly than at any time during the past 1,000 years, according to new research.

A study by Swiss and German scientists suggests that increasing radiation from the sun is responsible for recent global climate changes.

Dr Sami Solanki, the director of the renowned Max Planck Institute for Solar System Research in Gottingen, Germany, who led the research, said: "The Sun has been at its strongest over the past 60 years and may now be affecting global temperatures.

"The Sun is in a changed state. It is brighter than it was a few hundred years ago and this brightening started relatively recently - in the last 100 to 150 years."

Of course we still have greenhouse gases cited, but if it is actually the sun that is brighter, there is absolutely nothing we can do about it. The sun is over 332,000 times more massive than the Earth. That is just a little less than the Empire State Building compared to two half ton trucks.
