Climate change is a better term than global warming because it describes changes beyond rising temperatures. If temperatures continue increasing, it will have disastrous consequences globally. The main cause is a rise in CO2 emissions from burning fossil fuels and other human activities. This is causing sea levels to rise and more extreme weather, threatening more people with issues like droughts and starvation. Both individuals and governments need to take action to reduce emissions and mitigate the effects through sustainable energy use, carbon limits, and adaptation measures like flood defenses.
