These graphs from the NOAA’s Annual Greenhouse Gas Index show that there is an issue occurring by the increasing amount of greenhouse gasses getting added into the atmosphere. Focusing specifically on the bottom left graph, we can see the rise of Methane (CH4) in parts per billion, from 1975 to 2020. The measurement of the amount of methane in our atmosphere can be measured in various ways. We can measure and get the data for these graphs by looking at the point sources, external tracers, enclosed chamber data collection, and micrometeorological techniques that measure total methane emissions from individual sources/small open source areas. Satellites are able to measure various gasses while orbiting the earth. 

This parameter of rising methane collecting in our atmosphere matters to the global climate because it is creating a barrier that is trapping in heat. This is contributing too much to the greenhouse effect causing too much heat to be trapped. This causes adverse effects that largely affect climate trends and the wellbeing of the planet. This graph is important because it is showing that the amount of methane getting omitted into the atmosphere is increasing over time. This data lets us know that our production methods that release methane have become too prominent and need to be lessened. 

This data trend means that on average, more methane is being released into the atmosphere. This graph shows the ppm of methane omitted which correlates to the amount of heat that becomes trapped in the atmosphere because of the properties of the collected gas.
