consequences:
- many of the world’s coastlines dramatically change
- 1 trillion dollar losses per year just in coastal cities
- floods
- waves break later and hit the coast with far greater force
- 1m rise in sea levels would hit the critical level in NY
- trade is reliant on sea levels
- greenland’s ice is melting
- sometimes it’s not profitable to protect a region, they have to be abandoned
measures:
- no way to prevent
- raise public awareness
- projections for rising sea levels
- sea barriers like venice’s MOSE
- expert’s help from the netherlands
- dyke
- raising houses
- floodgates
- protect our climate
letter to the editor:

comment on an article
-
addresses the magazine, not the author
-
does not directly critize the author
-
no ”Dear Sir/Madam”, just ”Sir/Madam”
-
”unless carbon emissions are cut significantly and coastal defences strengthened”, ”the benefits of action are greater.” ⇒ some places cannot be protected regardless
-
”300 million” more like 400 million
-
”640 million people could be threatened by 2100” there are 1 billion people expected to live in coastal ares by the end of the century
-
”a more sophisticated assessment of the topography of coastlines around the world” ⇒ even more modern approaches use sea level measurements and most importantly land measurements since not only does the sea rise but land also sinks (land subsidence)
-
sea level rise also varies strongly, the world mean is at 3mm/year where as in Indonesia the sea rises 9mm/year
