It’s quite amazing how the rise of the average temperature of just a few degrees has such an enormous effect on our ecosystems. It just shows how fragile our plant is.

Climate fluctuations cause evapotranspiration in the underwater plant life..
This decreases the sea-levels and the amount of oxygen in the water which in turn harms aquatic life. u14301815

@ DS Moosa , you are right we need to reduce the destruction our ecosystems endure. But HOW? At some point we have to stop asking how and take charge be innovative, know what is being done and as future leaders take charge. @ Keagan Loader it’s not that we are looking at the effects on complex organisms now, we have recently realised that the marine population is endangered and we found out WHY so now complex organisms are treated with a sense of urgency because without them we are also going to become extinct. The truth is we’ve ruined our planets resources and now we find that we cannot make them ourselves and that the Earth requires thousands or millions of years to recover. Greed has changed the way things were, what good is it for a government to make fishing laws if they are violated? What good is it for certain companies to pay tax because of their carbon emissions while in other countries carbon tax is not encouraged? What we all need is to dream of a day when it’s too late to save Earth from ourselves.

The disruption of marine ecosystems due to climate change occurs rapidly. Scientists have stated that it could possibly take hundreds, if not thousands of years for organisms to recover. There seems to be a rapid loss in marine diversity due to low levels of oxygen present in the sea water. With that being said, we need to limit the tremendous changes in climate in order to reduce the destruction of ecosystems.

In all studies of global warming and it’s effects on the organisms,has it helped to finding its share in causing the mass ancient mass extinctions?

According to Carl Zimmer a research study has shown that the world’s coral reefs has declined by 40 percent due to higher temperatures. This can lead to extinction of organisms that depend on coral reefs to live. The increase in CO2 causes the seawater to become more acidic. According to Dr. McCauley if we limit the industrialization of the oceans to some regions it can allow threatened species to recover in different regions.

The research on the effects of relatively rapid warming and associated oxygen loss in the sea on invertebrate communities is very interesting, but what about research on the present sea floor ecosystems? If research on sea floor ecosystems from 3400 to 16100 years ago indicate that local extinctions took place, couldn’t research be done about the organisms living in sea floor ecosystems currently put in danger by global warming and climate change, in order to try to find a way to prevent local extinctions today?

Over the years there have been countless studies surrounding the effects global warming has had on our oceans and the organisms that call it home. What I don’t understand is why it is only now that we are looking at the effect it will have and has had on the more complex organisms? Surely if they are more connected to their environment and can give us a better idea of the potential consequences to their ecosystems, they should be some of the first organisms to be looked at?
