Ace\u0219tia contribuie, de asemenea, la identificarea sursei apei suplimentare care provoac\u0103 aceast\u0103 cre\u0219tere. Topirea ghe\u021barilor \u0219i a ghe\u021bii marine reprezint\u0103 o cauz\u0103 major\u0103. De asemenea, apa din m\u0103rile noastre se dilat\u0103 atunci c\u00e2nd se \u00eenc\u0103lze\u0219te, contribuind \u0219i mai mult la aceast\u0103 cre\u0219tere.<\/p>\n<p>Totu\u0219i, observarea P\u0103m\u00e2ntului din spa\u021biu nu se rezum\u0103 doar la nivelul m\u0103rii.
