Present hype in news about Great Barrier Reef coral bleaching is timed to promote signing of the Paris climate agreement.
http://www.abc.net.au/lateline/content/2015/s4447275.htm

There is dead coral just about everywhere in the world and worsening, coinciding with devastation of the whole world ocean environment.

Consider a few examples of what is happening.

Chile Dec 2015.
337 whales dead:

Chile March 2016.
23 million salmon dead:

Argentina Oct 2015.
Largest die off of whales ever recorded. N.B. Algae cannot increase without adequate nutrient:

Whole world ocean fish stocks were thought to be inexhaustible LOL:

Sewage and land use nutrient overload-pollution proliferating algae is the fundamental cause of devastated coral and seagrass food web nurseries.

Invasive algae takes up available oxygen, causing small or large dead zones that suffocate the coral polyp animal and the zooxanthellae algae at night and under dense cloud when photosynthesis is not occurring, when plant life consumes oxygen instead of producing it.

Animals including fish do not breed successfully during food shortage, good reason why over 30 years of fishing restrictions and worldwide EEZ's have fundamentally failed to prevent ongoing whole world ocean fish and ecosystem devastation, including coral ecosystems.

Solutions?
Don't just focus on emissions involving air pollution.
Urgently reduce the sewage nutrient loading being dumped in ocean ecosystem currents daily.

Here we go again, wasting time & effort on AGW !

It does not matter whether global warming is real or not.
The solution to global warming is promoted as being
leave oil & coal in the ground.
Well, if you have not noticed less CO2 is being put into the air
than previously each year.
The reason, oil demand is falling and coal consumption while rising
is costing more.
Any new sources of oil are at very expensive costs.
Deloitte predicts 30 to 50 percent of oil & oil service companies
will go bankrupt THIS YEAR !

The largest coal company Peabody is already bankrupt this year.
The major oil companies have spent Two Trillion dollars on oil search
and do not look like getting it back from production.
The crux of the matter is our economies can not afford the cost of
new energy. Once the mix of new & old exceeds the Goldilocks price
then we are in real trouble.

We need an urgent push for base load power. We know solar & wind
cannot do it on its own, we cannot afford to cover multiple overcast
still days, so be it nuclear or something new it needs urgent attention.

Percentage percentage percentage wrong wrong wrong, if you look into the following 'news' and comments. LOL

Ahh, I haven't been here for a while but it is a little nostalgic to see the wilfully ignorant, and the determinately delusional, accelerating their anti AGW rhetoric in the face of record global temperatures.

However the tactic of turning up the volume when the facts are staring you in the face serves to accentuate the what a collection of buffoons the anti AGW lot have become.

I'm sure even as their ranks dwindle there will always be little cohorts of holdouts in places like OLO. Just as the Flat Earth Society still very much exists today http://www.theflatearthsociety.org/cms/ it will be become a place for our next generation to visit and chortle at the quirky collection of cantankerous blowhards who were so hell bent on ignoring the bleeding obvious.

Don Aitkin set out to rebut the claim that 97 per cent of climate scientists support three propositions: that the earth is warming, this is caused by human activities and is dangerous. He uses statistics on papers from climate scientists to say that there is not widespread support for the propositions. But scientific papers do not set out to test such broad questions, so it is not surprising that few such papers are found.

It can be difficult to accept unpleasant advice from experts, but it is not productive to ignore it. There is a broad consensus amongst climate scientists that that the earth is warming, this is caused by human activities and it is dangerous. For practical purposes, there is no doubt that there is a problem and it is of our own making: the question now is what do we do about it?

If you have empirical scientific evidence that substantiates your assertion that human activities have caused dangerous global warming, then don't keep it secret. Table it.
