the major cause for the recent global climate change is

Answer 1

human activity, particularly the burning of fossil fuels such as coal, oil, and gas for energy, transportation, and industrial processes. This releases large amounts of greenhouse gases, primarily carbon dioxide, into the atmosphere, trapping heat and causing the planet to warm up. Other human activities such as deforestation, agriculture, and waste disposal also contribute to greenhouse gas emissions and exacerbate the climate change problem. While natural factors such as volcanic eruptions and changes in solar radiation can also affect the climate, the current rates of warming far exceed any historical natural variability and are clearly linked to human activity.
