A F\u00f6ld a \u2018Goldilocks\u2019 bolyg\u00f3. Se nem t\u00fal meleg, se nem t\u00fal hideg. Ennek k\u00f6sz\u00f6nhet\u0151en a mi vil\u00e1gunk az egyetlen olyan hely, amelyet ismer\u00fcnk, ahol a v\u00edz g\u00e1z, folyad\u00e9k vagy szil\u00e1rd anyag (j\u00e9g) form\u00e1j\u00e1ban is el\u0151fordulhat.<\/p>\n<\/div>\n

T\u00e9len \u00e1ltal\u00e1ban j\u00e9ggel tal\u00e1lkozunk, de a sarkvid\u00e9keken \u00e9s a magas hegyek cs\u00facsain eg\u00e9sz \u00e9vben j\u00e9g van.<\/p>\n

A sz\u00e1razf\u00f6ld legnagyobb j\u00e9gtakar\u00f3i az Antarktiszt \u00e9s Gr\u00f6nlandot bor\u00edtj\u00e1k. Az \u00c9szaki-sarkvid\u00e9ken is hatalmas j\u00e9gter\u00fclet tal\u00e1lhat\u00f3, de ez meglehet\u0151sen v\u00e9kony, \u00e9s az \u00f3ce\u00e1non lebeg. A j\u00e9gsapk\u00e1k \u00e9s a hegyi gleccserek gyakran n\u00f6vekednek vagy zsugorodnak. Manaps\u00e1g sok tud\u00f3s \u00fagy v\u00e9li, hogy a glob\u00e1lis felmeleged\u00e9s miatt a j\u00e9g olvad, a tengerszint pedig emelkedik, ami n\u00f6veli az \u00e1rvizek vesz\u00e9ly\u00e9t.<\/p>\n

Hossz\u00fa t\u00e1von az olyan m\u0171holdak adatai, mint az ESA ERS \u00e9s Envisat m\u0171holdjai, k\u00e9pesek t\u00e1j\u00e9koztat\u00e1st ny\u00fajtani arr\u00f3l, hogy mi t\u00f6rt\u00e9nik.<\/p>\n
