John has been assigned a research project on climate change. He starts by collecting information from various sources, including books, websites, and scientific journals. After gathering the data, John organizes the information into different categories and identifies key concepts related to climate change. He then critically evaluates the credibility and reliability of each source and cross-references the information to ensure accuracy. John synthesizes the collected data and presents it in a comprehensive report, highlighting the causes, impacts, and possible solutions to climate change.
