Final answer:
Global warming increases greenhouse gas levels in the atmosphere, enhancing the greenhouse effect and causing climate change. This results in altered weather patterns, ecosystem disruptions, and rising sea levels, with far-reaching impacts on agriculture, biodiversity, and human settlements.
Step-by-step explanation:
Global warming affects the atmosphere by increasing the levels of greenhouse gases such as carbon dioxide and methane. These gases trap heat within the Earth’s atmosphere, leading to the phenomenon known as the greenhouse effect. This warming leads to global climate change, manifesting as altered global weather patterns, an increase in global temperatures, and a myriad of associated environmental issues.
Climate change has wide-reaching impacts on the Earth’s ecosystems. For instance, as global temperatures rise, weather patterns become more unpredictable, affecting precipitation and leading to more intense storms and weather events. Notably, such changes influence agriculture, biodiversity, and can even alter ecosystems like the intertidal zone. Additionally, climate change can cause rising sea levels, threatening coastal communities and ecosystems.
The haze-effect is another atmospheric phenomenon, which arises from volcanic eruptions and leads to a temporary cooling effect on global climate. However, this effect is usually short-lived compared to the persistent warming caused by increased greenhouse gases. Moreover, the health of ecosystems and survival of various species, including heterospecifics, are affected as their habitats are altered or destroyed due to shifting climatic conditions.
