OK, but I don't see how a youtube video, from someone who readily admits that they know nothing about the science, and claim that the sun affect (by NASA) is a myth, really counts, either.
Anyway, just to rebuke the "NASA Myth part":

SUN’S DIRECT ROLE IN GLOBAL WARMING MAY BE UNDERESTIMATED, DUKE PHYSICISTS REPORT
At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities, two Duke University physicists report.
The physicists said that their findings indicate that climate models of global warming need to be corrected for the effects of changes in solar activity. However, they emphasized that their findings do not argue against the basic theory that significant global warming is occurring because of carbon dioxide and other “greenhouse” gases.
Nicola Scafetta, an associate research scientist working at Duke’s physics department, and Bruce West, a Duke adjunct physics professor, published their findings online Sept. 28, 2005, in the research journal Geophysical Research Letters.....

NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming
Report indicates solar cycle has been impacting Earth since the Industrial Revolution
Some researchers believe that the
solar cycle influences global
climate changes. They attribute recent warming trends to cyclic variation. Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.
Now, a
new research report from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate
data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution....
Both of these studies, done by NASA, show that the Sun and its cycles influence 'Global Warming', so no, it is not a "Myth". Sorry, but I give the guy on that video as much creedence as the folks at 'Loose Change'.
