That is not what I am saying. That happens yearly. I stated every 100 THOUSAND years the earth is a little closer and a little further away from the earth/. I have posted this numerous times (see Global warming or cycles of the sun thread).
Sorry, missed that part about 100 thousand years. If that's the case...why would the climate change so dramatically in just a 20 or 30 years? Wouldn't it take at least 100s of years to see signifigant chagne?
As supplier of almost all the energy in Earth's climate, the sun has a strong influence onclimate. A comparison of sun and climate over the past 1150 years found temperatures closely match solar activity (Usoskin 2005). However, after 1975, temperatures rose whiles olar activity showed little to no long-term trend. This led the study to conclude, "...during these last 30 years the solar total irradiance, solar UV irradiance and cosmic ray flux has not shown any significant secular trend, so that at least this most recent warming episode must have another source."
In fact, a number of independent measurements of solar activity indicate the sun has shown a slight cooling trend since 1960, over the same period that global temperatures have been warming. Over the last 35 years of global warming, sun and climate have been moving in opposite directions. An analysis of solar trends concluded that the sun has actually contributed a slight cooling influence in recent decades (Lockwood 2008).
