Global climate change is a critical issue that affects many aspects of life on earth. One significant impact of this change is that weather patterns become increasingly extreme and unpredictable. Common weather phenomena, such as rain, wind and temperature, have undergone drastic changes in recent decades. One of the direct impacts of climate change is an increase in global temperatures. According to the Intergovernmental Panel on Climate Change (IPCC) report, the Earth’s average temperature has increased significantly since the industrial era, with major consequences for weather patterns. This increase in temperature contributes to faster evaporation of water, resulting in weather that is more humid in some regions and drier in others. This condition causes an increase in the frequency and intensity of tropical storms. Regions such as the Caribbean and North Atlantic are experiencing more cyclones, which not only bring heavy rain but also cause flooding and damage to infrastructure. Research shows that warmer oceans can provide more energy to hurricanes, making them stronger and potentially more destructive. Apart from that, the El Niño and La Niña phenomena are also increasingly affected by climate change. Changes in sea surface temperatures in the Pacific can trigger extreme weather patterns around the world. El Niño is often associated with rainier seasons in some parts of the world, while La Niña can cause drier conditions. Changes in the frequency and strength of these phenomena disrupt food security and public health. Another bad impact is the increase in drought events. Many regions, especially those dependent on agriculture, face serious threats due to lack of water. Prolonged drought could result in a food crisis and threaten the survival of millions of people. In this case, efficient irrigation and new technologies in agriculture are important to overcome the turmoil caused by climate change. Not only that, climate change also has an impact on snow and ice conditions in the polar regions. Ice retreat in Greenland and Antarctica not only threatens wildlife habitats, but also causes sea levels to rise. Large coastal cities, such as New York and Jakarta, face a greater risk of flooding due to melting ice. The disruption caused by climate change is not only physical, but also impacts social well-being. Unpredictable weather and more frequent natural disasters could trigger migration, conflict and impacts on mental health. Scientists warn that the most vulnerable people are those already struggling in difficult economic conditions. The importance of addressing global climate change cannot be ignored. Adaptation and mitigation are the two main strategies that need to be implemented. Reducing greenhouse gas emissions, using renewable energy sources, and increasing public awareness are key steps that need to be taken to keep the earth habitable for future generations. The implementation of green technology and environmentally friendly policies is not only the responsibility of governments, but also of individuals and companies throughout the world. Thus, the impact of global climate change on world weather has far-reaching and complex consequences. It is important for all parties to work together to face this challenge for the sake of survival and the preservation of our planet.
