Read the passage and decide whether the statements are True or False.

When considering the relationship of drought to climate change, it is important to make the distinction between weather and climate. Weather is a description of atmospheric conditions over a short period of time, while climate is how the atmosphere behaves over relatively long periods of time.

Individual drought periods can be understood as discrete weather events. Climate changes occur over longer periods and can be observed as changes in the patterns of weather events. For instance, as temperatures have warmed over the past century, the prevalence and duration of drought has increased in the American West.

Global climate change affects a variety of factors associated with drought. There is high confidence that increased temperatures will lead to more precipitation falling as rain rather than snow, earlier snowmelt, and increased evaporation and transpiration. Thus the risk of hydrological and agricultural drought increases as temperatures rise.

Much of the Mountain West has experienced declines in spring snowpack, especially since mid-century. These declines are related to a reduction in precipitation falling as snow (with more falling as rain), and a shift in timing of snowmelt. Earlier snowmelt, associated with warmer temperatures, can lead to water supply being increasingly out of phase with water demands.

While there is some variability in the models for western North America as a whole, climate models unanimously project increased drought in the American Southwest. The Southwest is considered one of the more sensitive regions in the world for increased risk of drought caused by climate change.

2. Patterns of weather events can be observed to identify climate changes.

3. There will be more snow which melts earlier when temperatures increases.

4. Water supply doesn’t match the demand properly with warmer temperatures.

Read the passage and choose the best answer to each of the following questions.

The glaciers of the Himalayas and the Andes could disappear in this century. As a result, the millions of people in India, Bolivia and Peru who now depend on melting water from mountain glaciers could find themselves in a critical situation. The ice sheet of Greenland is also melting more quickly than the scientists predicted. Greenland’s largest outlet glacier, the Jakobshavn Ibra glacier, is moving toward the sea twice as fast as it was in 1995. One cause could be meltwater that runs down to the bottom of the glacier and gets between the ice and the rock below. This water makes it easier for the glacier to slide along to the ocean.

Many ice researchers believe that Greenland’s melting, if it continues, will add at least three feet to global sea levels by the year 2100. If the ice sheet of Antarctica, now largely unaffected, begins to melt, the next few conturies could see a six-foot rise in sea levels, forcing tens of millions of people out of their homes.
