The statement that best explains why scientists are increasingly concerned about the effect of methane gas emissions on global climate is that the Methane gas has a higher global warming potential (GWP) than carbon dioxide does, so it can trap more heat in the atmosphere.
Global warming is also called climatic change because of the existence of heating of Earth's climate system which are primarily due to human activities.
