How to graph global warming?

Does this sunspot graph support the claim that the Sun is causing global warming?

  • A certain global warming 'skeptic' has been using this graph to claim that NASA believes the Sun is causing the current global warming: ...show more

  • Answer:

    There are papers challenging your conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun’s impact on Earth over the course of the 11-year solar cycle. The study below, led by scientists at the High Altitude Observatory of the National Center for Atmospheric Research (NCAR) and the University of Michigan, finds that Earth was bombarded last year with high levels of solar energy at a time when the Sun was in an unusually quiet phase and sunspots had virtually disappeared. “The Sun continues to surprise us,” says NCAR scientist Sarah Gibson, the lead author. “The solar wind can hit Earth like a fire hose even when there are virtually no sunspots.” The study, also written by scientists at NOAA and NASA, is being published today in the Journal of Geophysical Research – Space Physics. It was funded by NASA and by the National Science Foundation, NCAR’s sponsor. Scientists for centuries have used sunspots, which are areas of concentrated magnetic fields that appear as dark patches on the solar surface, to determine the approximately 11-year solar cycle. At solar maximum, the number of sunspots peaks. During this time, intense solar flares occur daily and geomagnetic storms http://wattsupwiththat.com/2009/09/17/ncar-number-of-sunspots-provides-an-incomplete-measure-of-changes-in-the-suns-impact-on-earth/ You should always check for the latest NCAR information before posting!

The sun warms the Earth...yes! But does the sun warm the Earth at a constant rate? The Sun has cycles, just as everything else in nature. But, those cycles involve hundreds and thousands of years. The Warmers point to tree rings that say we have cycles, yet most scientists will now tell you that tree rings are very undependable for dating. Yet Lefty historians try to early-date important historical events (like the explosion of Santorini) using tree rings. You can't have it both ways! Me thinks that's more likely than CO2 warming anything!

No. Astrophysicists will not support that claim.

No. The denialists have used this graph a lot. BUT Notice that it is ten years out of date. The graph the denialists show is TEN YEARS out of date, and since then the sunspot effect and global warming have diverged. The professional denialists must KNOW this! They're not daft.

It supports the claim that the sun influences our climate, yes.

Sure it does. It shows that solar activity has increased and leveled off at one of the highest levels in over a thousand years. Some say 8000 years. http://physicsworld.com/cws/article/news/18692 http://www.space.com/scienceastronomy/sunspot_record_041027.html

You are assuming that NASA's temperature was not manipulated...... Bad assumption. P.S. Give the points for 'best answer' to someone besides me..... I don't need them.

No, of course not. I mean you would have to be practically brain dead to interpret it that way. In fact, if a person, or peoples interpretation of such a thing could be so misguided, imagine all the other rubbish in this person, or peoples heads!! Now there is something to frighten, astonish, and confound all in one!

The sun will shoot out a bright fire thingy on 12/21/2010 and it will make earthquakes and fires and floods that will ruin all of our nice stuff. Global warming is something the government people are using to make sure no one figures out what is going on until it is too late. That way no one will make trouble and they can get on their giant boats which the rich smart people.
