Trends in Atmospheric Carbon Dioxide - BioInteractive

In 1958, Charles David Keeling began measuring atmospheric carbon dioxide at the Mauna Loa Observatory on the big island of Hawaii. This figure is a graph of the observatory’s measurements over time, which is now called the Keeling Curve. The “Educator Materials” document includes a captioned figure, background information, graph interpretation, and discussion questions. The “Student Handout” …

Mauna Loa Observatory - NASA

The longest continuous record of atmospheric carbon dioxide levels (1958-present) comes from Mauna Loa Observatory in Hawaii. In many ways the mountain is the ideal location for studying the atmosphere. Isolated in the Pacific, it is far from major sources of pollution. Its high-altitude, lava-coated flanks are free of plants and trees, whose cycles of photosynthesis and respiration affect carbon …

Mauna Loa carbon dioxide forecast for 2021 - Met Office

We forecast the annual average CO 2 concentration at Mauna Loa to be ± parts per million (ppm) higher in 2021 than in 2020. As a result, we forecast the 2021 annual average CO 2 concentration at Mauna Loa to be ± ppm (Figure 1). Figure 1. Forecast CO 2 concentrations at the Mauna Loa observatory, showing monthly (red curve ...

25/06/2020· Fifth, year-over-year comparisons of Mauna Loa CO2 gives people a signal of planetary significance. It's true that Mauna Loa is just a spot on the map. But the year-over-year trend in the Mauna Loa CO2 is essentially the same as the trends at other observing stations. “CO 2 is rising everywhere, and at about the same rate” (Volk, 2008, pp ...
