On January 4th, Earth reaches its closest point to the Sun, known as perihelion, which results in a 6.7% increase in solar intensity compared to summer. The timing of perihelion shifts over thousands of years due to Earth's axial precession, affecting climate patterns; if perihelion occurred in June, Northern Hemisphere summers would be warmer and winters colder. The discussion also touches on the complexities of Earth's orbital cycles and their influence on ice ages, noting that the current understanding involves cycles of 20,000, 41,000, and 100,000 years. Additionally, the role of land distribution in the Northern Hemisphere is highlighted, as it impacts seasonal snow and climate feedback mechanisms. Overall, the thread emphasizes the importance of understanding solar dynamics and their long-term effects on Earth's climate.

So, what do you think it's going to be?


Lots and lots of grant requests!

I mean if these are legitimate discrepancies (and I'm not enough of an expert to say if they are or are not), then it ought to be possible to get some money to figure them out. Of course, they won't give the money to anybody. But a person with the right credentials ought to able to. Wether the answer will be #1 or #2, it is not for me to say.



BTW;

This thread has gone a long way off topic, which was orignally about the Perihelion.
If anybody wishes to discuss the perihelion, then please feel free to add to this thread. However, if it is another topic, then please start a new thread.

Thanks,
