Annotated Summary
Lindsey, R. (2020, August 14). Climate change: atmospheric carbon dioxide . Climate.gov. https://www.climate.gov/news-features/understanding-climate/climate-change-atmospheric-carbon-dioxide In this article, Lindsey (2020) reported that the global average carbon dioxide in 2019 reached 409.8 parts per million (ppm). The concentration reached its peak as compared to figures for the past 800,000 years. The increase in carbon is largely due to the burning of fossil fuels for energy. Fossil fuels consist of carbon that plants drew out from the air millions of years ago, and we humans are bringing the carbon back into the air by burning fossil fuels in a span of several hundred years. Lindsey stated that atmospheric carbon dioxide rose 100 times faster in the past 60 years compared to non-human increases 11,000 years ago. Lindsey mentioned that greenhouse gases stores heat and radiates it slowly as time passes. While carbon dioxide does not take in as much heat per molecule when compared
