Question

multiple choice 1 point
what is the primary cause of the current rise in earth’s mean surface temperature?
natural climate cycles
release of greenhouse gases from burning fossil fuels
changes in earth’s orbit around the sun
increased solar activity

Explanation:

The current rise in Earth’s mean surface temperature is primarily due to human - induced emissions. Burning fossil fuels (like coal, oil, gas) releases greenhouse gases (e.g., carbon dioxide, methane) into the atmosphere. These gases trap heat, leading to global warming. Natural climate cycles, changes in Earth’s orbit, and increased solar activity are either not the primary cause currently or have been ruled out by scientific research as the main driver of the recent rapid temperature rise.

Answer:

Release of greenhouse gases from burning fossil fuels
