Reading Passage

Time: 3 minutes

The }at stream Is an irregular band of wind that occurs in high altitudes at

about 20,000 leet, that is, between 6 and 9 miles above the surface of the

Earth Consequently, the jet stream wanders near the top of the Earth's

tropo-sphere, and, coincidentally, that is exactly where most 01 the Earth's weather

patterns occur It Is helplullo think ollhe jet stream like a river 01 air thaI occurs

at several different locations, but in generai llows from west to east over the

middle latitudes Technically, to be called a }at stream, the winds should be

moving faster than 57 miles an hour, but it can have average core speeds of

190 miles per hour, and in the winter, when the jet stream is strongest, winds

have been clocked al 300 miles an hour For the most part, the winds are

stronger In the winter because during the winter months the surface l

empera-ture contrasts more with the temperature in the troposphere To put that

another way, the greater the contrast in Ihe temperature of the Earth and the

atmosphere, the stronger the jet stream winds will blow

In general there are two jet streams between the equator and the North

Pale The subtropical }at stream tends to hover around the southern border 01

the continental United States, whereas Ihe polar jet stream blows over Idaho

and Montana The condition that causes these two streams is the diHerence in

the temperature between the tropic and the arctic regions of the Ea h, which

tends to concentrate in small zones called fronts It Is along these fronts that

storms tend to develop The jet streams blow the storms along their path When

the jet stream is over an area, strong storms may move into it but when the jet

stream has dipped oUl of the area, calm, dry weather will probably be forecast

Perhaps the most pervasive climatic eHect at global warming Is rapid esca

-lation at ice mell Mount Kilimanjaro in AlriCa, portions 01 the South American

Andes, and the Himalayas will verj likely lose most at their glacial ice within the

next two decades, aHecting local water resources Glacial ice continues its

retreat in Alaska NASA scientists determined that Greenland's ice sheet is

thinning by about I m per year The additional meltwater, especially from conti

-nental ice masses and glaciers, is adding to a rise In sea level worldwide Satel

-lite remote sensing is monitoring global sea level, sea ice, and continental ice

Worldwide measurem9nts~ that sea level rose during the last centurj

Surrounding the margins at Antarctica, and constituting about 11% 01 its

surface area, are numerous ice shelves, especially where sheltering inlets or

bays exist Covering many thousands of square kilometers, these ice sllelves

extend over the sea while still attached to continental ice The loss 01 these ice

shelves does not slgnlflCanlly raise sea level, for they already displace

seawa-ter The concem is for the possible surge of grounded continenlal ice Ihat the

ice shelves hold back Irom tile sea

Although ice shelves constantly break up to produce icebergs, some large

sections have recently broken free In 1998 an iceberg (150 km by 35 km)

broke ofllhe Ronne Ice Shelf, southeast of the Antarctic Peninsula In March

2000 an Iceberg tagged B-15 broke off the Ross tce Shelf (some goo longitude

west 01 the Antarctic Peninsula), measuring 300 km by 40 km Since 1993, sill

ice shelves have disintegrated in Antarctica About 8000 km of ice shelf are

gone, changing maps, Ireeir"IQ up islands to circumnavigation, and creating

thousands of Icebergs The larsen Ice Shelf, along the east coast 01 the

Antarctic Peninsula, has been retreating slowly for years larsen-A suddenly

disintegrated in 1995 In only 35 days in early 2002, Larsen-B collapsed into

icebergs This Ice loss is likely a result 01 the 2.soC temperature Increase in the

region in the last 50 years In response to the Increasing warmth, the Antarctic

Peninsula is sporting new vegetation growth, previously not seen there

-+ A loss of polar Ice mass, augmented by melting 01 alpine and mountain

glaciers (which e)(perieilCed more than a 30% decrease in overall ice mass dur

-ing the last centurj) will aHect sea-level rise The IPce assessment states that

'between one-third to one-hall of the elCistlng mountain glacier mass could di

s-appear over the next hundred years." Also, "there Is cOn:cI9S!Vit evidence lor a

worldwide recession of mountain glaciers This is among the clearest and

best evidence for a change in energy balance at the Earth's surface since the

end of the 19th century."
