Question

What is the effect of “global warming” on aquatic life?

Answer 1

That depends on the aquatic life.

Some like it and some don't.

Answer 2

death.

Answer 3

death!!!!! changes in temperature.... Way more water..........

Answer 4

It was just this effect that led the DNR to study El nino.Some areas of marine life were having exceptional spawning records while others, were marginal or below peak years.As far as determining the carbon sequestration process of oceans.It's not as easy as local fluvial and some lacustrine environments.We may understand the process but have yet to solve the real dynamics behind it.It is more noticeable in areas that are readily visible such as deltas,reefs,marshes,tidal barriers,and estuaries.One has to consider the natural buffer zones such as vegetation,sand dunes,and mans influence such as Dams and buildings to make it a whole,not just warming.     http://cdiac2.esd.ornl.gov  

I hope that link works if it doesn't just type in Ocean Carbon Sequestration on web search.

Answer 5

Global warming increases the global temp but may not be noticeable to humans. But what harms the Aquatic life is the melting of the ices. These will cause the dilution of the sea water which will then be detrimental to all creatures living on these waters. Even the fresh water aqua life will be be affected by it.

Answer 6

Warmth is generally beneficial.  Corals for example need warm water.  Those corals living in marginally cold water should be benefited from any warming.  Obviously corals living at the upper extreme of their temperature tolerance wouldn't do so well with warming.  I used the example of corals because alarmists will invariably use corals as an example and then find some at the upper range of temperatur tolerance and pretend this is the fate of all corals.  It is not.  Warming, if too much,  will cause the algae in the corals to die which will almost certainly leave the corals bleached and dying. Warming typically reduces the level of dissolved oxygen.  Some animals will die, others will thrive.  Those that are adapted to colder water will be stressed.  Those that are adapted to warmer waters should thrive.  

The comment about acid rain and dilution by ice cap melting is not a problem at all, just more hysteria. The claim that additional CO2 in the atmosphere leading to more carbonic acid leading to dissolving corals is also hysteria and not based on fact.

Answer 7

Global warming leads to acid rain.. I think you know that..

The term 'acid rain' is commonly used to mean the deposition of acid component in rain, snow, fog, dew, or dry particles. They are the result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. The smoke that comes from a fire or the fumes that come out of a car exhaust don't just contain the sooty grey particles that you can see - they also contains lots of invisible gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain".

On lakes and river water, acid rain has a diverse effect. Both the lower Ph and higher aluminum concentration in the surface water that occur as a result of the acid rain can cause damage to fish and other aquatic animals. At pHs lower than 5 most fish eggs will not hatch and lower pHs can kill adult fish. As lakes become more acidic biodiversity is reduced. Acid rain has eliminated insect life and some fish species.

Answer 8

a lot of fish can stop going to tanning beds to get that tan look- they'll all look much tanner, and sexier...the chick fish will be drawn even more to the dude fish...

Answer 9

once co2 is dissolved in water it forms bicarbonate and carbonic acid - as atmospheric levels rise the oceans uptake more (in competition with increasing ocean temperature) - Therefore increasing atmospheric CO2 should decrease the pH of the oceans. Melting ice removes the natural ecosystems for many animals and decreases salinity which can alter ocean currents.

coal(especially) and oil combustion releases heavy metals like mercury into the atmosphere because these fossil fules contain high levels of these metals - much of this ends up in the oceans - this has been confirmed by increasing mercury levels inside many aquatic animals including whales and fish we eat - such as tuna.

Answer 10

What people need to understand:

Warm waters are far more potent than warm air!

Warm air can't really effect water near as much as warm water effects air temperatures.

The earth's weather is driven by warm or cool oceans - remember El Nino & La Nina.

The Alarmists believe coral in the 'great barrier reefs' will disappear  - however they are now recovering because the oceans around Australia are now cooling:

http://www.livingissues.com/index.php?op...

"The report shows that some of the areas worst hit by massive bleaching in 1997-98 have begun to recover."

Oceans temperatures one year ago:

Ocean temperatures today - several degrees cooler:

This is what Alarmists fail to understand - The heat that warms oceans comes from beneath (under the lithosphere) = the very hot magma working through the relatively thin 'crust'.

Answer 11

A good example is to take a look at the Great Barrier Reef where the rise of ocean temperature due to global warming is killing off the coral reefs. The videos coming out of the area are very alarming. Death to the coral reefs cause many other forms of aquatic life to die as well.

Answer 12

Global warming causes the icecaps to melt.

As more icecaps melt, the salt levels in the sea water around the globe start to diminish.

This will cause a lot of plankton to die out.

Plankton is right at the bottom of the food chain. Wiping out a load of plankton will have a knock-on affect and you'll start to see species further up the food chain start to die out or reduce to critical numbers. For example, a certain type of whale (is it the blue whale?) lives only on plankton, so they'd probably all die too.

The loss of salt levels in sea water will affect loads of other lifeforms apart from plankton, this is just one example.
