I Understanding the Impact of Solar Radiation and Eccentricity on Earth's Climate

AI Thread Summary
Solar radiation received at the same latitude is generally equal, but local climatic conditions can create variations. Factors such as weather patterns, moisture content, and atmospheric particulates influence the actual solar radiation that reaches the ground. For example, areas like the Gobi Desert may experience more sunny days compared to locations like Waverly, Iowa, despite being at the same latitude. Regarding Earth's eccentricity, predictions suggest it will increase over the next 1,000 years, potentially impacting climate patterns. Understanding these dynamics is crucial for assessing future climate changes.

I have two questions

(1) If we have two areas, for example one in America and the other on Asia, both with the same latitude φ, which one of the areas will receive more Solar Radiation? Or will it be the same?

(2)
If Earth's eccentricity graph for the past 750k years is this

based on that, the eccentricity will get increased again in the next 1000 years? And what will that mean for Earth's climate?

if both at the same latitude, it will be the same ... is there a reason you thought that it would possibly be otherwise ?

Barring climactic variations. e.g. the Gobi desert (~42 degrees north latitude) probably gets more sunny days per year than Waverly, Iowa (~42 degrees north latitude).

Solar radiation is same for both. Differences due to weather differences (rain, clouds, etc.).

That depends on whether you are measuring solar radiation hitting the top of the atmosphere or solar radiation hitting the soil.
 
Moisture content of the local atmosphere ...particulates ... dust , sand if the prevailing wind mostly comes from land areas .

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
