The primary trend of climate change is the increase in global temperatures, commonly referred to as global warming. This phenomenon is largely driven by rising greenhouse gas emissions from human activities such as burning fossil fuels, deforestation, and industrial processes. These emissions trap heat in the atmosphere, leading to various environmental changes, including more frequent and severe weather events, rising sea levels, and changes in ecosystems and biodiversity. Climate change poses significant risks to natural habitats, agriculture, and human health, prompting global efforts to mitigate its effects through international agreements and sustainable practices.
