Which increases the amount of thermal energy on Earth according to scientists?

Question

An increase in greenhouse gases has trapped heat.

More heat from Earth’s core is being conducted to the surface.

There is more convection occurring on Earth.

The sun has grown brighter.

Answer 1

The statement that most accurately describes what increases the amount of thermal energy on Earth according to scientists is:

An increase in greenhouse gases has trapped heat.

This phenomenon is a key factor in global warming and climate change, as greenhouse gases (like carbon dioxide and methane) trap heat in the Earth's atmosphere, preventing it from escaping into space and leading to an overall increase in the planet's thermal energy.
