Which of these is the best example of a positive feedback loop in earth's climate system? a. as the number of plants decreases, the amount of co2 decreases. b. as climate warms, co2 increases because plants remove less of it. c. high precipitation results in increased plant growth, lowering co2. d. high clouds have a high albedo and reflect solar energy back into space.

The correct answer is B) As the climate warms, CO2 increases because plants remove less of it.

The statement that is the best example of a positive feedback loop in Earth's climate system is "As the climate warms, CO2 increases because plants remove less of it."

That is why it is very important that governments of the world pay close attention to climate change and facilitates research and solutions to mitigate the consequences of global warming. Most countries had signed the Kyoto, Japan, protocol, in which they accepted to reduce CO2 pollutants. The United States did not sign the agreement.
