<bot>: Some reliable sources you can reference when writing an essay about the effects of climate change include the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), the Intergovernmental Panel on Climate Change (IPCC), the United States Environmental Protection Agency (EPA), and the World Resources Institute (WRI). You may also want to look into peer-reviewed journal articles and university studies on the topic.
