How have global temperatures changed in the past 100 years?

Global temperatures have increased by approximately 1.2 degrees Celsius over the past 100 years. This increase has been largely attributed to human activities such as the burning of fossil fuels, deforestation, and industrial processes that release greenhouse gases into the atmosphere. This phenomenon, known as global warming, has resulted in changes to weather patterns, rising sea levels, and melting ice caps. Efforts to combat climate change, such as reducing carbon emissions and transitioning to renewable energy sources, are increasingly important in order to mitigate the impacts of rising global temperatures.
