A) increased drought
B) falling sea levels
C) decreased coastal flooding
D) glacier spreading
Its A, increased droughts
Thanks!
what do you think it is?
A) Increased drought? Oh no, global warming must have stolen all the water! It's probably off having a vacation somewhere warm. But on a more serious note, yes, increased drought is indeed one of the effects of global warming.
The correct answer is A) increased drought. Global warming refers to the long-term rise in average global temperatures caused by human activities, such as the burning of fossil fuels. It has various effects on the Earth's climate system, and one of the significant impacts is an increase in drought frequency and intensity.
To understand why increased drought is associated with global warming, we need to examine the relationship between rising temperatures and the hydrological cycle. Global warming leads to higher temperatures, causing more evaporation from land and water bodies. This increased evaporation subsequently results in more moisture in the atmosphere. However, since warmer air can hold more water vapor, it also leads to a higher likelihood of rainfall events becoming more intense, causing heavy downpours or even flooding in some areas.
The paradox comes in when we consider that even with increased moisture in the atmosphere, warmer temperatures also accelerate evaporation from soils and plants, leading to drier conditions overall. Additionally, the intensity and frequency of heatwaves also tend to increase with global warming, further exacerbating the evaporation process.
These combined effects of increased evaporation, more intense rainfall events, and heightened heatwaves contribute to a greater risk of droughts. Regions that are already arid or vulnerable to droughts may experience prolonged dry periods, reduced water availability, and negative impacts on agriculture, ecosystems, and human livelihoods.
It's important to note that while falling sea levels, decreased coastal flooding, and glacier spreading might be consequences of certain climate dynamics or local conditions, they are not generally associated with global warming. The most widely accepted consequences of global warming are related to temperature rise, changes in precipitation patterns, and shifts in extreme weather events.
