Changes in Earth's total insolation can be caused by variations in the distance between Earth and the Sun due to the Earth's elliptical orbit (Milankovitch cycles), changes in the Earth's axial tilt, and variations in the transparency of the atmosphere due to factors like greenhouse gas concentrations and volcanic activity.
Sunspots
The temperature decreases by about 6.5 degrees Celsius per kilometer in the troposphere, so the total temperature change between 3 km and 7 km above the Earth's surface would be approximately 26 degrees Celsius.
The total landmass of Earth is approximately 57.5 million square miles or 148.9 million square kilometers.
The temperature typically decreases by 6.4°C for every 1 km increase in altitude in the troposphere. So, the total temperature change between 3km and 7km above Earth's surface would be around 25.6°C, calculated by multiplying the lapse rate by the difference in altitude (6.4°C/km x 4km).

A change in Earth's total insulation can be caused by variations in the Sun's output, changes in Earth's orbit, or alterations in the composition of Earth's atmosphere such as increased greenhouse gas concentrations.

Changes in the Earth's orbit, variations in solar output, changes in atmospheric composition (such as greenhouse gas concentrations), and presence of natural phenomena like volcanic eruptions can all affect the Earth's total insolation.

The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
That is a total eclipse of the sun.
