<\/a>La \u00eenceput de secol XXI, una din problemele majore cu care se confrunt\u00e3 \u015fi se va
\nconfrunta omenirea \u00een viitor \u00eel reprezint\u00e3 fenomenul \u00eenc\u00e3lzirii globale.
\nEfectul asupra florei \u015fi faunei globului – deja o obi\u015fnuin\u0163\u00e3 \u00een presa scris\u00e3 \u015fi audio-vizual\u00e3 din \u00eentreaga lume – a ajuns \u00eentr-un stadiu critic.
\nPrincipala cauz\u00e3 a acestui fenomen are la origine activit\u00e3\u0163ile desf\u00e3\u015furate de comunit\u00e3\u0163ile umane. Astfel c\u00e3 oamenii de \u015ftiin\u0163\u00e3 au tras un semnal de alarm\u00e3 aduc\u00e2nd la cuno\u015ftin\u0163a \u00eentregii umanit\u00e3\u0163i c\u00e3 viteza de topire a calotei glaciare a atins un nivel record.
\n\u00cen anul 2007, calota glaciar\u00e3 a ajuns la cele mai sc\u00e3zute cote \u00eenregistrate \u00een ultimii 30 de ani de supraveghere prin satelit. Un studiu realizat de NASA a demonstrat c\u00e3 23% din pierderi s-au \u00eenregistrat \u00een decursul ultimelor ierni.
\n\u201eTopirea ghe\u0163ii \u00een timpul iernii devine astfel principala cauz\u00e3 pentru nivelul alarmant de topire. \u00cen urm\u00e3torii 25 de ani calota glaciar\u00e3 arctic\u00e3 va disp\u00e3rea pe timp de var\u00e3. \u00cen lipsa emisiilor de gaze cu efect de ser\u00e3, aceast\u00e3 situa\u0163ie nu ar fi fost niciodat\u00e3 posibil\u00e3\u201c… a spus cercet\u00e3torul Walt Meier de la National Snow and Ice Data Center- NSIDC (SUA).
\n\u00cen ultimii ani ghe\u0163arii s-au topit extrem de mult ceea ce a dus, \u00een zona Polului Nord, la formarea unei noi rute navigabile \u00eentre Oceanul Pacific \u015fi Oceanul Atlantic. Altfel spus, de acum \u00eencolo exist\u00e3 o \u201escurt\u00e3tur\u00e3\u201c \u00eentre Europa \u015fi Asia.
\nRegiunile polare sunt foarte sensibile la schimb\u00e3rile climatice, iar unii oameni de \u015ftiin\u0163\u00e3 prev\u00e3d c\u00e3 ghe\u0163arii vor disp\u00e3rea din zona arctic\u00e3 p\u00e2n\u00e3 \u00een 2040. Anali\u015ftii sus\u0163in c\u00e3 \u00eenc\u00e3lzirea global\u00e3 se manifest\u00e3 \u00een regiunea arctic\u00e3 de dou\u00e3 ori mai repede dec\u00e2t \u00een celelalte locuri de pe planet\u00e3.
\n\u201eAm observat c\u00e3 ghe\u0163arii au sc\u00e3zut la doar 3 milioane de kilometri p\u00e3tra\u0163i\u201c, a declarat Leif Toudal Pedersen, de la Centrul Spa\u0163ial Na\u0163ional Danez.
\nArctica nu beneficiaz\u00e3 \u00een momentul de fa\u0163\u00e3 de un statut interna\u0163ional similar Antarcticii, practic ea put\u00e2nd fi revendicat\u00e3 \u015fi exploatat\u00e3.
\nPentru protejarea Antarcticii a fost \u00eencheiat un Tratat care stabile\u015fte statutul interna\u0163ional al continentului, tratat ce a fost semnat de 12 state (Argentina, Australia, Belgia, Chile, Fran\u0163a, Japonia, Noua Zeeland\u00e3, Norvegia, Africa de Sud, Uniunea Sovietic\u00e3, Anglia, Statele Unite ale Americii) \u00een 1959 \u015fi a intrat \u00een vigoare \u00een 1961. Rom\u00e2nia a semnat acest Tratat \u00een 1971, fiind cea de-a 17-a \u0163ar\u00e3 care a aderat la acesta. \u00cen prezent aproape 50 de \u0163\u00e3ri au semnat Tratatul.
\nEmisiunea filatelic\u00e3 cu tematic\u00e3 special\u00e3 este urmarea ini\u0163iativei pre\u015fedin\u0163ilor statului Chile \u015fi al Finlandei lansat\u00e3 \u00een 2007. \u00cen deplin consens Administra\u0163iile Po\u015ftale din cele dou\u00e3 \u0163\u00e3ri au propus \u015fi altor state s\u00e3 se al\u00e3ture programului de a se realiza o emisiune de m\u00e3rci po\u015ftale av\u00e2nd ca tem\u00e3 protejarea regiunilor polare \u015fi a ghe\u0163arilor. O serie de \u0163\u00e3ri nordice ale Europei dar \u015fi Australia, Canada, Noua Zeeland\u00e3, Brazilia, Africa de Sud, precum \u015fi multe alte \u0163\u00e3ri
\ns-au al\u00e3turat acestui proiect. Printre acestea se num\u00e3r\u00e3 \u015fi Rom\u00e2nia.
\nTimbrele emise de \u0163\u00e3rile participante vor avea acela\u015fi \u00eensemn specific: simbolul grafic al unui cristal de ghea\u0163\u00e3, l\u00e2ng\u00e3 care, statele semnatare ale Tratatului Antarctic, vor ad\u00e3uga \u015fi conturul continentului alb.<\/p>\n
