Climate change is a long-term rise in global temperatures, driven largely by human activities like burning fossil fuels. This causes severe impacts such as extreme weather, rising sea levels, and species extinction, with the worst effects felt in vulnerable regions. Mitigating climate change requires reducing consumption, increasing renewable energy, and protecting natural carbon sinks. International efforts, like the 2015 Paris Agreement, aim to limit global temperature rise, while individuals can reduce their carbon footprint through sustainable practices. Collective actions also play a crucial role in addressing climate change on a global scale.
