With infrared measurements taken since 1980, it is clear the planet is warming. What is remarkable is that this has occurred without any contribution from automobile traffic, energy power plants or any other activity of man. How do we know this? Because the planet we are talking about isn’t Earth, but Neptune. Yes, that’s right, according to recently published studies by Colorado’s Space Science Institute, Neptune has been getting brighter from 1980 to 2004, and infrared measurements confirm the planet is heating up. Since a similar warming has also occurred on Mars, and solar activity is presumed the culprit, it appears these new findings present yet another new twist to this hot topic of global warming!
