Read passage (1) Between burning fossil fuels and clearing forests, humans emit far more carbon dioxide than Earth's natural physical and biological processes can remove from the atmosphere. (2) Fundamental to any attempts to understand, slow, or reverse the buildup of atmospheric carbon dioxide is a global accounting of where it's released and stored. (3) That's why scientists at NOAA's Earth Systems Research Laboratory created Carbon Tracker: a carbon dioxide measuring and
modeling system that tracks sources and sinks around the globe.
(4) When it comes to carbon dioxide's influence on Earth's surface temperature, the only thing that really matters is the bottom line: how much there is in the atmosphere. (5) But when it comes to understanding how natural processes and human activities influence that bottom line, everything matters: where and when the carbon is released, where and when it's sequestered, how weather and climate and human decisions influence surface carbon fluxes.
(6) Those details are critical not only for predicting future climate change, but also for understanding how agricultural and ecological
systems will respond to rising carbon dioxide concentrations. (7) Being
able to say with confidence where and how much carbon dioxide is stored and released by different landscapes and activities will also be a prerequisite for evaluating carbon mitigation strategies.
Humans add carbon dioxide to the atmosphere faster than the Earth's biological processes can remove it.

What is the main idea of the passage?

A. Since carbon dioxide contributes to climate change, it is important to understand where and when carbon is released into the atmosphere.

B. Human activity, such as burning fossil fuels and clearing forests, is a primary cause of increasing carbon dioxide into the Earth's
atmosphere.

C. The burning of fossil fuels contributes to the increase of carbon dioxide in the Earth's atmosphere.
