The National Oceanic and Atmospheric Administration (NOAA) recently reported that carbon dioxide levels in the atmosphere have reached an average daily level above 400 parts per million, a concentration not seen for at least three million years. “We know that the Earth is warming, sea ice is disappearing, the glaciers are receding, the oceans are acidifying, and sea levels are rising. We know all of this from climate science research and monitoring. And, we now know that we have reached this carbon dioxide milestone of 400 parts per million thanks to a NOAA observatory on top of the volcano Mauna Loa in Hawaii that has been continuously monitoring and collecting data related to atmospheric change since the 1950s. The research being done at NASA, NOAA and other agencies is providing the crucial data that will enable us to assess, adapt to, and move forward on this critical issue. We must continue investing in this work.” - Congresswoman Eddie Bernice Johnson
