Final answer:
An increase in cloud cover is seen as an atmospheric disturbance linked to climatic changes. The rise in greenhouse gases like carbon dioxide leads to an increase in Earth's temperature and alters precipitation patterns, impacting both ecosystems and human societies.
Step-by-step explanation:
An increase in cloud cover due to higher moisture content in the atmosphere is an example of an atmospheric disturbance. When examining changes in global climate change and precipitation patterns, it's important to understand the cause-and-effect relationship between increased greenhouse gases and the alteration of weather patterns. An increase in carbon dioxide and other greenhouse gases leads to a rise in Earth's temperature. This warming effect, also known as the greenhouse effect, can cause changes in weather conditions that directly impact ecosystems and human societies.
Regarding the effect on a forest ecosystem where trees accustomed to decades of predictable water availability suddenly face drought stress, we can predict several consequences. The trees with high stomatal density during a drought may engage in negative feedback by reducing transpiration to conserve water, thus potentially reducing the local humidity and further exacerbating the drought conditions. This alteration to the hydrological cycle can lead to changes in the forest's biodiversity and productivity, and could eventually result in a shift in the ecosystem structure if the trees fail to adapt.
Cities like New York, Bogotá, and Manila might face challenges such as increased flooding, strain on infrastructure, and water management issues as they adapt to these new precipitation patterns. Meanwhile, a rise in temperature enhances evaporation, leading to more water vapor in the atmosphere, which can result in increased precipitation. This forms a complex dynamic with both positive and negative feedback loops within ecosystems, influencing temperature and precipitation cycles along with the overall weather conditions.
