1) When sunlight reaches the Earth's surface, it can either be reflected back into space or absorbed by the Earth. Once absorbed, the planet releases some of the energy back into the atmosphere as heat. Greenhouse gases (GHG) like water vapor (H₂O), carbon dioxide (CO₂), and methane (CH4) act like a blanket, absorbing energy, slowing or preventing the loss of heat back into space. This process is commonly known as the "greenhouse effect." This graph shows the increase in greenhouse gas (GHG) concentrations in the atmosphere over the last 2,000 years. What conclusion could be supported by the data? A) B) () D) Levels of GHGs should level off in the next few years based on current trends shown in the graph. Increases in concentrations of GHGs since 1750 are due to human activities in the industrial era. Fluctuations in levels of GHGS are normal and are caused by natural processes that ebb and flow over time. Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change, having increased more than any other GHG since pre- Pedrerial times

1) When sunlight reaches the Earth's surface, it can either be reflected
back into space or absorbed by the Earth. Once absorbed, the planet
releases some of the energy back into the atmosphere as heat.
Greenhouse gases (GHG) like water vapor (H₂O), carbon dioxide (CO₂),
and methane (CH4) act like a blanket, absorbing energy, slowing or
preventing the loss of heat back into space. This process is commonly
known as the "greenhouse effect." This graph shows the increase in
greenhouse gas (GHG) concentrations in the atmosphere over the last
