These facilities could be impacted by long - term (> 100 years) rising sea levels; however, the range of currently estimated short - term rise in sea levels suggest that neither facility would be impacted within the current lifespan of the projects (< 20 years),» the company said in March 2017.

Third, using a «semi-empirical» statistical model calibrated to the relationship between temperature and global sea - level change over the last 2000 years, we find that, in alternative histories in which the 20th century did not exceed the average temperature over 500-1800 CE, global sea - level rise in the 20th century would (with > 95 % probability) have been less than 51 % of its observed value.

Having said that, it is a really small effect — if the entire Arctic summer sea ice pack melted (average thickness 2 metres, density ~ 920 kg / m3, area 3 × 10 ^ 6 km ^ 2 (0.8 % total ocean area) = > a 4.5 cm rise instantly which implies a global sea level rise of 0.36 mm.

It seems to me that he makes a good case for «more alarmism», i.e. scientist must speak out and say that we should seriously consider a sea level rise > 1 m on a century scale, because there is a non-negligible possibility of that happening.

During this time, the islands were subjected to ongoing sea level rise and the passage of a notable typhoon... which caused severe damage with its > 100 knot winds and abnormal wave heights... caused a decrease in total island land area of approximately five percent, yet Ford and Kench write that «despite [this] significant typhoon - driven erosion and a relaxation period coincident with local sea - level rise, [the] islands have persisted and grown.»

As Media Matters has noted, the IPCC's 2007 «Synthesis Report» concluded that» [w] arming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level» and that» [m] ost of the observed increase in global average temperatures since the mid-20th century is very likely [defined in the report as a» > 90 %» probability] due to the observed increase in anthropogenic [human - caused] GHG [greenhouse gas] concentrations.»

I mean the process is supposedly that CO2 warms the atmosphere > atmospheric heat is then absorbed by the ocean > deep ocean heat causes sea levels to rise due to thermal expansion.
