A lot of people were saying that the changes in temperature had to do with solar flares and is not from the increase in green house gases we've been releasing into the atmosphere. Well here's a news flash for you. For the last few years we've been experiencing increasing warming and the solar activity has been at an extreme low. In fact we may be heading for another solar period similar to the mid 1600's when the earth went into a mini ice age because solar activity weakened so much. Maybe...
That's a big maybe and no one really knows. And all the talk by the naysayers has to do with this lul in solar activity. It may continue and it may not no one knows. We don't have a good enough understanding of how the sun functions to make even an educated guess.
If the sun remains relatively dormant for several decades the greenhouse gases will be a good thing.
If the sun comes back to life in a few years global warming will take off uncontrollably.
At some point the sun will come back to life.
Do we want to be prepared or not?
