Global warming is caused by increases in greenhouse gases like carbon dioxide and methane in the atmosphere. China is currently the largest emitter of greenhouse gases, releasing over 6,000 million metric tons annually. Other major emitters include the US, Russia, India, and Japan. Greenhouse gas emissions come from various sources like transportation, industry, power stations, agriculture, and deforestation. Effects of global warming include reduced agricultural production due to higher temperatures and less rainfall, as well as more frequent extreme weather events and natural disasters. Actions needed to address global warming involve developing more sustainable agricultural practices, increasing forest coverage, reducing emissions from vehicles and industry, and adopting renewable energy sources.
