Bye, Bye Alexandria: A 1-Meter Sea Rise is Certain
Posted on 12/10/2012 by Juan
COP18, the Climate Change Conference held in Doha, Qatar, is a dismal
failure, with the United States and Russia being the chief villains. The
failure of the world's leaders to have their hair on fire about the extreme
challenges of the climate change we are producing with our carbon dioxide
and other greenhouse gas emissions has imperilled some countries more than
others. Subsaharan Africa is in the firing line for the worst effects of
climate change. But the low-lying areas of West Bengal and Bangladesh, and
of the Egyptian Delta, are especially vulnerable to the one-meter sea level
rise that the COP18 failure has ensured will occur within 80 years.
Here at geology.com there is a useful web tool that lets you see what the
world looks like with a 1-meter (about three feet) sea level rise, which is
now certain to occur by the end of this century. Actually, in past eons, a
one-degree Centigrade increase in average temperature has produced a 10-20
meter rise in the seas. We are certainly going to exceed a 2-degree C.
increase, so we could see a 20-40 meter increase, i.e. 60 to 120 feet.
Obviously that would put a lot of our current land under water, but it will
take a long time for that extreme rise to occur. The seas are very cold,
very deep and very big, and circulate slowly, so that they will take
thousands of years to warm. Once they do, human beings will be in big
trouble. And even these enormous, icy bodies of water will warm up a bit by
2100, causing sea level rises of at least a meter, and maybe two. This is
what Egypt would look like with a one-meter rise (and no, you can't build
sea dikes to deal with that kind of increase):
The city of Alexandria, celebrated in the poetry of Cavafy and the novels of
Lawrence Durrell- with its 4.5 million population- has no more than 80 years
to live. Note that Alexandria is bigger than Chicago (inside city limits),
America's third-largest city. The Delta city of Damanhour, where Muslim
Brothers and their rivals clashed last week, leaving a young man dead? Under
water. The ports of Damietta and Rosetta? Gone.
Alexandria is a key port for Egypt, with necessary infrastructure, through
which 4/5s of the country's imports are brought in.
A one-meter/ yard increase in sea level will inundate much of Egypt's
fertile Delta, displacing at least 10% of the country's people and bringing
salt water into the country's breadbasket.
Among all the countries of the world, Egypt is among those most at risk from
human-induced climate change. Given the Aswan Dam, they are not big
polluters themselves.
If I were Egypt, I'd sue the US and China for the tort of making a tenth of
the country or more sink beneath the waves.
