Is manmade global warming just an occult?

You may have done yourself a service by reading the articles you posted. You would also have done better to not have linked to page 2 of the NatGeo article, the page that starts off by saying how wrong the concept of solar activity causing climate change is, especially on Mars. And the NASA article doesn't even suggest that solar activity is related to climate change. And the Times article is made moot by the NatGeo article. In other words, you have made a better case for the manmade climate change argument than for the no manmade climate change argument with these articles. Thank you very much.
