Human activities have a big effect on the weather around the world, often causing problems for nature. The main reasons for this are greenhouse gas emissions, cutting down trees, and how we build cities. These actions change the natural balance of our climate in ways that can be really bad.
First, burning fossil fuels releases a lot of carbon dioxide and other greenhouse gases into the air. This causes a "greenhouse effect," which traps heat and makes the Earth warmer. The Intergovernmental Panel on Climate Change (IPCC) says that since the late 1800s, the Earth's surface temperature has risen by about 1.1°C mainly because of things people have done. This warming changes weather patterns, leading to more intense heatwaves, longer dry spells, and sudden, strong storms.
Next, cutting down trees (deforestation) plays a huge role in climate change. Trees help absorb carbon dioxide, which helps cool the Earth. But when we clear big areas of forests for farming or to build cities, we lose that carbon storage. This means more carbon gets released back into the air, making global warming worse. In places like Brazil, which has a lot of the Amazon rainforest, the weather has changed, leading to different rainfall patterns. Fewer trees mean less moisture, making once-wet places drier.
Urbanization, or the growth of cities, is another important factor. As cities expand, they create "urban heat islands." This means temperatures can be much warmer in cities than in surrounding areas. This happens because materials like concrete and asphalt absorb more heat, there are fewer plants, and energy use increases. The higher temperatures in these areas can change local weather, including how much it rains and how storms develop.
Agriculture also adds to climate change. For example, raising livestock produces methane, a greenhouse gas that is even stronger than carbon dioxide. Farming methods that use a lot of fertilizers also release a gas called nitrous oxide. Together, these gases make climate change worse.
In short, human activities like burning fossil fuels, cutting down forests, and building cities are changing the weather around the globe. The effects are serious: from rising temperatures affecting ecosystems to more extreme weather events. To tackle these problems, we all need to work together to reduce emissions, protect forests, and plan our cities in a smarter way. It’s about minimizing risks to create a stable climate for future generations. It starts with recognizing our role and responsibility in facing this global challenge.
