The Discovery of Global Warming

The discovery of global warming involves understanding that the Earth’s atmosphere is trapping more heat due to increased levels of greenhouse gases, mainly from human activities like burning fossil fuels. Scientists observed rising temperatures over decades through careful measurements. In the late 19th and early 20th centuries, researchers identified the greenhouse effect and connected it to industrial emissions. Continuous data collection and climate models confirmed that human activity is significantly contributing to warming. This understanding has led to the recognition that urgent actions are needed to reduce greenhouse gases and slow climate change.
