 The 21st century has ushered in an era of unprecedented climate change, posing major challenges to the international community. As the Earth's temperature continues to rise, the effects of this phenomenon are being felt in a variety of areas, from ecosystems and agriculture to human health and the economy. Understanding the complexity of climate change and its far-reaching impacts is essential to developing effective mitigation and adaptation strategies. The Science of Climate Change Climate change is a long-term change in weather patterns and average temperatures on Earth, caused primarily by human activities that release greenhouse gases into the atmosphere. These gases, such as carbon dioxide (CO2), methane, and nitrous oxide, trap the sun's heat and cause global warming. This process, known as the greenhouse effect, has been accelerated by the significant increase in greenhouse gas emissions since the Industrial Revolution. Observations over the past century have shown a c...
