5 Global Warming Questions

Here's a couple more questions for you to ask. One is why should we believe these same scientists when thirty years ago they were saying we were either in or about to enter an ice age? Second, you talked about NASA but you didn't mention NASA's most stark discovery and that was that in the same time period Earth was warming that Mars was warming even more than Earth did. While Earth has gone up .6 degrees celsius, Mars has gone up .65 degrees celsius. Why is that? To answer those questions and yours it is because we were having an increase of sunspot activity. When we had the cold to make the middle-child scientists scream about ice age it was due to lack of sunspot activity. Why the entire northern hemisphere had one of the coldest winters on record this past years was also blamed on lack of sunspot activity. Just some things people should know.
