Global warming is causing the Earth's temperature to increase by 0.8 degrees Celsius per decade due to excessive greenhouse gas emissions from deforestation and fossil fuel use. This climate change results in higher temperatures, more natural disasters, and lower agricultural yields, as seen in recent events like delayed monsoons in Nepal, heat waves in India and California, floods in Pakistan, and melting glaciers and snow peaks. Recommended remedies include reducing waste, recycling, forestation, and developing alternative energy sources.
