Question

1 Which one of the following factors has not contributed to the Earth's temperature deviations over thousands of years? *
2 points
A. Changes in radiation from the Sun
B. Changes in historical periods
C. Changes in Earth's orbit.
D. Changes in Volcanic activity​

Answer 1

Answer:

C) Changes in Earth's orbit.

Answer 2

Answer:

The answer is B. Changes in historical periods.

Explanation:

Many natural processes have contributed to this, including fluctuations in the sun, volcanic eruptions, variations in Earth's orbit, and carbon dioxide levels (CO2). It can take hundreds of millions of years for global climate change to occur.

Scientists have made substantial progress in the data, theory, and modeling of Earth's climate system, allowing them to estimate future climate change with more confidence. Despite this, a number of significant challenges make precise projections of how global or regional temperature trends will evolve decade by decade in the future impractical.
