[Coral-List] Diver impacts to reefs

     A long post follows.  Executive summary:

    1. there are both natural and human impacts on reefs, natural ones are
not a worry, human ones are causing the reef declines.
    2. mass coral bleaching, caused by increasing sea temperatures, is
already among the greatest causes of reef damage, diver damage is a very
small cause.
    3. mass coral bleaching is the greatest threat to reefs in the future,
if it is not reduced we will loose our reefs.  Totally eliminating ALL
other human impacts to reefs WILL NOT save the reefs.  Only stopping the
global warming that causes mass coral bleaching, coupled with reducing
other impacts, can save the reefs.  Not solving this problem will cost the
diving industry very dearly in coming decades.
    4. we will have to limit global warming to a total of about 2 degrees C
to save coral reefs (and the planet as we know it).
    5.  we need the dive community to call on society as a whole and
governments, to take serious action on climate change.

      There are both natural and human-caused impacts on coral reefs.
Anyone who has seen what a hurricane (typhoon, cyclone) can do to a coral
reef knows the power of nature (for example, Stoddard long ago documented
the effects of a hurricane that hit the reefs of Belize which not only
broke the coral, but literally removed the whole spur and groove system).
On an island 1.5 million years old (relatively young) like I'm on, if
hurricanes average once in 5 years, then there have been about 300,000
hurricanes in the life of the island, yet the reefs are still here.  Some
rivers naturally release huge amounts of sediment, and while there may be
no reefs near the mouths of those rivers, farther away reefs still
flourish.  New Guinea, for instance, has high mountains with very high
rainfall, which results in huge natural sediment loads coming out of their
larger rivers.  But their country also has some of the world's most diverse
and amazing coral reefs (away from river mouths).  However, reefs have been
dealing successfully with the impacts of natural impacts for hundreds of
millions of years, and the reefs are still there.  I do not worry about
natural impacts on coral reefs, reefs are well equipped to deal with them.
      The impacts I worry about on coral reefs are the ones that come from
humans.  They tend to be chronic, with no time period for the reefs to
recover, while many of the natural impacts are acute, brief events with
time for reefs to recover.  Plus human damage happens on top of the natural
impacts, and human impacts are the cause of the reefs declining, not the
natural impacts, or reefs would have declined and disappeared hundreds of
millions of years ago.
      It is widely recognized in the scientific community that while there
is a long list of impacts from human activities on coral reefs, the most
damaging world wide include overfishing, destructive fishing,
sedimentation, nutrient runoff, and mass coral bleaching, other important
ones include crown-of-thorns starfish, coral disease, and recently
introduced species have increased in importance.  On this list, diver
impacts are low on the list.  All human impacts contribute to the
degradation of reefs.  Mass coral bleaching in 1998 killed an estimated 16%
of the world's corals, and devastated many reefs particularly in the Indian
Ocean.  Some or many reef areas there had coral mortality on the order of
90%.  Looking forward into the future, mass coral bleaching is predicted to
increase greatly, as the sea surface temperatures continue to steadily
increase, rising in a few decades to the point that every summer the water
is above the bleaching threshold.  Thus, many scientists think that mass
coral bleaching is the single greatest threat to coral reefs worldwide.
This is supported by studies like the Kennedy et al paper I cited, which
found that if we fixed ALL other human impacts, it would buy us about 10
years, after which the reefs would resume their decline with the ultimate
end point of reefs world wide no longer having enough corals left to add
calcium to the reefs, reefs would be in a negative balance loosing calcium
every year (and thus loosing rugosity as dead corals collapse, and loosing
ecosystem services as fish can't find hiding holes and fish populations and
catches decline.)  They would not be coral reefs anymore, they would be
primarily algae beds with a few scattered corals (as a some reefs already
are).
      My understanding is that China's economy has grown so rapidly that
now it is the world's second largest total emitter of carbon dioxide.  It
is quite true that on a per person basis, the USA and Australia are among
the highest emitters on the planet.  France produces only about 1/3 as much
emissions per person as the USA, proving that emissions can be greatly
reduced and a developed country standard of living maintained.  Australia
plans to reduce their emissions to very low levels and keep their standard
of living (but also keep selling coal and gas to China and South Korea).
China produces about 1/6 as much green house gas per person as the USA.
People in countries like China have just as much right to development as
people in already developed countries like the USA.  By the way, China
knows it has a problem and is hard at work on renewable energy and is
currently one of the world's largest producers of photovoltaic cells and
wind turbines.  But they will still be doubling the burning of coal as
their economy grows rapidly, and there is a proposal to ship so much coal
from the US that new ports on the US west coast are proposed that would
increase coal exports from 2 trains (of 100 cars each) a day to 37 entire
trains a day.  It is also very clear from the literature that although
there are a variety of natural sources of CO2 emission, that the natural
sources of CO2 emission were in balance with CO2 sinks such as plants that
use CO2 as they do photosynthesis.  If that were not the case, CO2 in the
atmosphere would have increased without limit.  Venus is a good example of
what results when that happens, the atmosphere there is made up primarily
of CO2 and sulfuric acid (if I remember) and the planet surface temperature
is about 7-800 degrees C (again if I remember).  In fact that has not
happened on Earth, and over the long haul CO2 sources have been in balance
with CO2 sinks (although in some geological periods there has been
significantly more CO2 in the atmosphere than present).  There is abundant
documentation, with the direct measurement record begun on top of a
mountain in Hawaii, that CO2 has been and is steadily rising in earth's
atmosphere.  The cause of the increase is entirely humans.  The baseline
level was due to natural processes, and thank heavens there was some CO2 in
the atmosphere, without it, earth would be an ice ball- the average world
temperature would be about freezing and the oceans would have gradually
frozen to the bottom.  We absolutely have to have the greenhouse effect to
keep from freezing, but it is increasing due to the vast amounts of
greenhouse gases humans release on top of the natural emissions, and things
like the cutting of forests (not just the cutting of tropical rainforests
that presently is occurring, but the forests of North America and Europe
and some other places, a large portion of which were cut in previous
centuries) which reduces the rate at which CO2 is taken out of the
atmosphere and sequestered in wood.  Other things contribute as well, such
as the release of large amounts of black soot from burning, which lands on
the land and on snow and ice, and absorbs light much better than snow and
ice and thus contributes to heating.
      Anyhow, it is very much the case that human releases of greenhouse
gases (primarily CO2 but also to a lesser extent methane, nitrous oxide,
and cfc's (refrigerant gases)) are the primary cause of current warming.
IPCC reports have documented that up to about 1970, natural things were a
large contributor to the warming, and presently natural things do
contribute to warming but much less than human-produced effects.
      The chain of causality is clear for all to see:  humans produce
greenhouse gases which add to natural sources, greenhouse gases (both
natural and human) warm the earth and the addition of human-produced
greenhouse gases causes the increase in temperature (while natural sources
kept the planet temperature at the natural temperatures that prevailed
before recent decades), and high ocean temperatures cause mass coral
bleaching and death.  There are many natural sources of coral mortality,
which are normally balanced by natural sources of coral reproduction and
growth, but these new sources of coral mortality add to the natural
mortality to overwhelm natural coral reproduction and growth.
      Net effect, is that in the future, human emissions of greenhouse
gases will kill the world's coral reefs, convert them to algae beds, IF we
continue emissions at present rates.  Removing ALL damage from humans, not
just diver damage but the big impacts like overfishing, sediment and
nutrients, will NOT save the reefs, just delay their death a decade or so.
The ONLY way to save reefs is to stop global warming, AND to reduce local
human impacts.
      IF we do nothing to stop global warming, and so far all efforts have
not slowed the increase in the rate of emissions (not slowed emissions, and
not even slowed the INCREASE in emissions) and emissions and their
increases continue to be at the highest levels predicted (there are a range
of predictions depending on what we do), then reefs will die.
      Bottom line: Stop global warming or kiss your reefs goodby.
(reducing diver damage is good, but it is a drop in the bucket)
                        It is in the medium-term self-interest of the dive
industry to support meaningful action to slow global warming.
      Cheers,  Doug
