Thread: 30-Year Cold Spell Strikes Earth

from the article:

Casey says the evidence is clear that the earth is rapidly growing colder because of diminished solar activity.

He says trends indicate we could be headed for colder temperatures similar to those seen in the late 1700s and early 1800s when the sun went into a "solar minimum" — a phenomenon with significantly reduced solar activity, including solar flares and sunspots.

hard to argue with him, the data does show the solar activity is decreasing. question is, is solar activity the primary factor in global temperature?

I guess if you switch off the sun, you would soon find out.........(clue) it would be pitch black and we would freeze.

where was it on the weekend?

There is one other factor that controls our weather. The way the earth moves back and forth on it`s axis. At the present moment we are starting the journey back to a ice age tilt. Will only take a few thousand years. So I would not worry too much. Might be a good idea to get the green house effect happening to keeps some of the heat in. But there are those that say the green house effect will cause more cloud cover that will reflect more sunlight and so not raise temperatures as much as first thought. Will be interesting if this is the latest climate trend and how as it become more obvious the climate change/ warming believers react to it. Going to be some good spin to back away from what they where so passionate about with out losing to much face.

i agree, however thats an extreme example.
if we instead say drop the suns output by 1%, what would be the result on earths global weather?

are you talking about earths orbit in relation to the ecliptic?

Now don't get me wrong doesn't the increased CO2 and other GW gases act like a big doona for the Earth? In spite reduced incoming Solar radiation the planet will retain a greater proportion of the heat normally lost and in particular lost during the previous cold periods (like the 1700s) when we didn't have such a big CO2 doona?

i know thats what i was taught at school and it was named the greenhouse effect but since then there has been research casting doubt on that theory.

in the distant past when earth was warming up, co2 levels only rose hundreds of years AFTER the warming, not before. this might indicate that the greenhouse effect doesnt work like we thought it did. what i understand its not conclusive though, it just points to something not being correct in the current greenhouse theory.
