no arguments. But I'm asking what effect whaling has on
the stability of the climate.

Most of the large whales feed on krill. Krill feeds on
phytoplankton that bloom in cold water if there is the
correct combination of nutrients and sunlight.
Fertilizer is essential to plant growth and the reduction
in both the species and numbers of whales, has limited the
available nutrients; whale *** being an important part of
the food chain.
With reduced plankton populations, the solar energy heats
the seawater at a greater depth than normal.

But isn't that made up by nutrients in the run-off from
intensive Western farming? If memory serves, I saw this
reason cited as one of the major causes of the death of the
Great Barrier Reef.



It's one reason. Corals can only survive within a very narrow range of
salinity and pH all of which has been altered beyond their ability to
endure. The oceans are becoming more acidic and warmer. While it is

true

that variations of temperature etc have taken place over the millennia,

they

have always occurred within timespans of thousands of years. At no

point is

there any evidence that it ever happened within 30 years as we are now
seeing. Doesn't give species a whole lot of time to adapt.

hey have all taken time over the span of thousands of years, but the
cusp

(or

critical tip over points) in each event happen within a narrow span of

that

longer time frame. without the experience of thousands of years of hard

data, it

could easily be that these past 30 years are nothing more than the cusp
of

a

much longer event.



The great barrier reef is hundreds of thousands of years old. So it is
safe
to say that in all that time there has not been a die off like we have
now.
And they can make these assessments because they can examine the deposit
layers.

Paul


so, over this entire event period, we are now at the cusp of the event.
thanks
for the support on this issue.

No, it points to a event that has never happened at least in the last half
million years. That is a change in climate over something as little as 30
years. So it disproves your opinion. We've got ice shelves that are 650
thousand years old and are now gone. Melted. And in that 650 thousand
years we've had a couple of ice ages as well as other climatic shifting.
But nothing so severe and so fast.
