Solar Maximum and global warming

solar maximumIt seems pretty much everyone agrees now that the earth is warming, and the extreme weather over the past week certainly seems to confirm that both the weather AND the climate is changing.  Steven Forrest’s July newsletter included an article about the current Solar Maximum which reminded me that I […]

The Sun is definitely waking up

After a prolonged “solar minimum,”  with record long periods without sunspots, the Sun has become extremely active again.  These periods of solar maximum alternating with solar minimum are a normal part of solar activity but the last solar minimum was particularly long: 12.4 years rather than the usual 11 years.

Solar scientists met last week to discuss the higher levels of solar activity that are likely as we move out of the Solar Minimum of the past few years.  The head of NASA’s Heliophysics Division says “our technological society has developed an […]

Low solar activity linked to cool UK winter

Last year’s cold winter sparked a huge resurgence into the global warming debate.  If the earth is warming, why did we have a cold winter?

We’ve been in a “Solar Minimum” since about 2006, a long period with virtually no solar activity.  I’ve been writing about this for quite […]

Are we heading into another “little ice age?”

Maybe the solar warming skeptics are on to something.  As you probably know, we are in a very deep solar minimum, with over 700 days with absolutely no sunspot activity since 2004. In fact, some scientists are beginning to speculate that sunspots may be gone for good:

“Sunspot magnetic fields are dropping by about 50 gauss per year,” says Penn. “If we […]

We are in Deep Solar Minimum

Thanks to Astrococktail for this link to a NASA article on the Solar Minimum, the expected period of low sunspot activity.  The Solar Minimum came right on schedule back in 2006, as I reported in this earlier article.  But this Solar Minimum is setting all kinds of records.

In 2008 the Sun was completely blank of sunspots 73% of the […]
