NOAA: Record increases in atmospheric methane may be evidence of a climate-related feedback loop

Scientists with the National Oceanic and Atmospheric Administration, or NOAA, have been tracking concentrations of atmospheric carbon dioxide and methane since the 1980s. For the second year in a row, methane gas has increased at a record-high rate compared to the previous year. Methane is one of the most powerful greenhouse gasses, which trap heat and contribute to increasing global temperatures associated with human-caused climate change.
