Human actions like burning fossil fuels, deforestation, and pollution increase greenhouse gases in the atmosphere, trapping heat and warming the planet. Scientific evidence includes rising global temperatures, melting glaciers, changing rainfall patterns, and more extreme weather events. Instruments like satellites, thermometers, and climate models provide data over decades, confirming climate change. This has consequences like rising sea levels and threats to biodiversity. Using science, we can understand these patterns and create solutions such as renewable energy, afforestation, and sustainable living. Observation, measurement, and experimentation help guide our actions to reduce environmental damage and protect Earth’s delicate balance.
