സമുദ്രനിരപ്പിന്റെ ഉയർച്ച
ആഗോളതാപനം മൂലമുണ്ടാകുന്ന സമുദ്രനിരപ്പിൽ ഉയർച്ച ഉണ്ടാക്കുന്ന പ്രശ്നങ്ങൾ
സമുദ്രനിരപ്പിന്റെ ഉയർച്ച എന്നത് ലോകത്തിലെ സമുദ്രങ്ങളിലെ ജലത്തിന്റെ വ്യാപ്തത്തിലുണ്ടാകുന്ന വർധനമൂലം ലോകവ്യാപകമായി ശരാശരി സമുദ്രനിരപ്പിലുണ്ടാകുന്ന ഉയർച്ചയാണ്. സമുദ്രങ്ങളിലെ ജലത്തിന്റെ താപീയവികാസവും അല്ലെങ്കിൽ ഐസ്ഷീറ്റുകളും, കരയിലെ ഗ്ലേസിയറുകളും ഉരുകുന്നതും മൂലം സമുദ്രനിരപ്പിലുണ്ടാകുന്ന ഉയർച്ചയ്ക്ക് കാരണമാകുന്നത് ആഗോള കാലാസ്ഥാമാറ്റമാണ്. കടലിലൂടെ ഒഴുകി നടക്കുന്ന ഐസ് ഷെല്ലുകളോ അല്ലെങ്കിൽ ഐസ് ബർഗ്ഗുകളോ ഉരുകുന്നത് സമുദ്രനിരപ്പ് ചെറുതായി മാത്രമേ കുറിക്കുന്നുള്ളൂ.
Trends in global average absolute sea level, 1880–2013.[1]
Changes in sea level since the end of the last glacial episode.
പ്രത്യേക മേഖലകളിലെ സമുദ്രനിരപ്പിന്റെ ഉയർച്ച ആഗോള ശരാശരിയേക്കാൾ കൂടുതലോ, കുറവോ ആകാം. ഇതിനെ സ്വാധീനിക്കുന്ന പ്രദേശികമായ ഘടകങ്ങളിൽ ടെക്റ്റോണിക് പ്രഭാവങ്ങൾ, കരഭാഗത്തിന്റെ താണുപോകൽ, വേലിയിറക്കം, സമുദ്രജലപ്രവാഹങ്ങൾ, കൊടുങ്കാറ്റുകൾ മുതലായവ സ്വാധീനിക്കാം. [3]
സമുദ്രതീരങ്ങളിലേയും ദ്വീപുകളിലേയും മനുഷ്യന്റെ ജനസംഖ്യയേയും സമുദ്ര ആവാസവ്യവസ്ഥ പോലെയുള്ള പ്രകൃതിദത്തമായ പരിസ്ഥിതിയേയും സമുദ്രനിരപ്പിന്റെ ഉയർച്ചയ്ക്ക് സ്വാധീനിക്കാൻ കഴിയും. [4]
