I've been reading a lot about the global warming and I'm wondering, how do I know it's real?

Well, scientists have been studying climate patterns for decades now, and they’ve observed that the Earth is getting warmer. There are many different factors that contribute to this warming, including increased emissions from burning fossil fuels, deforestation, and changes in land use. These changes can affect the amount of sunlight that reaches the Earth’s surface, which affects temperatures.
