Climate change is already affecting our planet in many ways - from rising sea levels to more frequent extreme weather events. The primary cause of current climate change is largely human activity, like burning fossil fuels, which adds heat-trapping gases to Earth's atmosphere. The consequences of changing climate are already being felt worldwide, affecting ecosystems, agriculture, and human settlements. Addressing climate change requires immediate action to reduce greenhouse gas emissions and adapt to the changes that are already occurring.</textarea>
