Pause in global temperatures ended but carbon dioxide not the cause : Comments
By Jennifer Marohasy, published 21/3/2016El Nino events are not caused by carbon dioxide. They are natural events which manifest as changes in ocean and atmospheric circulation patterns across the Pacific Ocean.

Those questions are a just what the doctor ordered for you. The single cell will use a percentage of the solar energy it is exposed to in photosynthesis. This energy is not then available to become heat. Inefficiency in the process allows some solar energy to be converted to heat in that cell. This less the amount used by the above photosynthesis. As the sun goes down this heat may indeed warm the water around it but the total warmth in the water will be less than if the cell was not there that day. The cell has prevented some solar energy from becoming heat in the water while it warms the water a lesser amount. 2) As above multiplied by the number of cells. So a larger amount of cooling. 3) The plankton may act as a blanket/insulator between water and wind. An example that may interest you has perhaps just recently happened in the Antarctic. Our planet grows by 55 tonnes of cosmic dust raining in each day. http://www.popsci.com.au/space/55-tonnes-of-cosmic-dust-fall-to-earth-every-day,401674 Our ever fluctuating magnetic and electric fields guide this in more at the poles. The Antarctic sea ice catches it and holds it. The dust can fertilise plankton. As the sea ice melts the dust drops in to do the job. Due to the Antarctic sea ice extent anomaly having grown large during the years the warmists said it was shrinking there was a lot of dust caught up in it. As the warmists began to claim that they predicted it would grow, it began to rapidly melt. This then released a lot of nutrient into the water. Since then the Antarctic has bee very very cold. https://kenskingdom.files.wordpress.com/2016/04/mar-16b-sp.jpg compared to(see 2011 to the end of 2015). http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/seaice.anomaly.antarctic.png Posted by Siliggy, Monday, 18 April 2016 10:47:00 AM

ant,
I did not miss your point, your point. But it seems you missed mine because you are fixated on emissions causing warming and sea level rise. You seem to have failed to comprehend my opinion that was in reply to your egg damage story. Look, it is known green turtles in the GBR region are starving and most informed people know starving animals undergo behavioural changes. Lets say a green turtle 2 weeks away from laying eggs is suddenly unable to find food and becomes weakened and lays her eggs nearer the water, not high on the beach as a strong turtle would. Or, let's say a high tide coupled with storm surge reaches higher areas of the beach where eggs have been laid, inundating the eggs with sea water. Let me inform you, ant, coral is dead almost everywhere and dead coral is not continuing to produce the rubble and coral sand that forms and maintains coral sand beaches. Shortage of coral sand and subsequent beach erosion is occurring due to nutrient overload and algae that has killed the coral. Grasp this aspect. Healthy live coral used to form a virtual breakwater. Live coral used to slow down wave surge, but now dead coral is usually covered with slimy algae that allows wave surge to slip and slide easily up onto beaches and into islands. Six month a year I live on such an island. You see, ant, sea level rise is not coinciding worldwide at about the same time, as a prudent person would expect if polar ice melt was adding to the whole world ocean. There is sea level rise in numerous areas where a high nutrient load and algae and warm water exist together. There are also warm nutrient poor clear current waters warmed elsewhere where algae exists. Nutrient becomes exhausted, algae dies and falls away. There are various possible reasons green turtle eggs become non-viable, not just the one you wrote about. Why and how can I "divert" the issue when you can reply and prove your point if you can?

Siliggy, Re Q.1. So some solar energy is converted to heat in algae and as the sun goes down that heat may warm water around it. Now, I am only looking for warmth at the surface where sea surface temperature is measured by satellite. Apart from direct radiation penetrating algae during photosynthesis, solar radiation also warms surface water and I think some of that surface water warmth transfers particle to particle into the surface water algae. Is the latter correct or not? Re Q.2. You say a “larger amount of cooling” in a larger amount of algae. Are you sure about that? I agree there would be a larger amount of algae mass that would cause shade beneath the mass and so cause a larger amount of cooling. But where does the heat go, the heat than would otherwise travel down slightly more if the shade did not exist? And remember, heat rises and I am only looking for the near surface increase in heat linked to algae. Re Q.3. I think the insulation property of algae plant matter would help protect the surface water from the cold water beneath a dense algae bloom. I think such a protected bloom would likely be in a suitable state able to cause precipitation if above water conditions are also suitable. I suggest think specifically about water surface warmth. On a sunny day after sundown for a few minutes or a few hours, do you think algae could help slow down uplift-escape of some surface water warmth, or have no impact Posted by JF Aus, Tuesday, 19 April 2016 8:40:25 AM

Siliggy,
Cosmic dust you refer to “helps” to fertilize plankton as they say. So cosmic dust would add to other natural nutrient that adds to nutrient from human sewage and land use. It is the total of the loading that sometimes amounts to pollution causing imbalance, negative consequences and damage. A lot of dust and soot also falls into the ocean and onto polar ice, dead algae too. Siliggy, I think the very very cold in Antarctica you refer to, depends on where and when temperatures are measured. Here on OLO we can look into algae in the Ross Sea. Scientists know there is a link between polar ice and the El Nino but they have not known what the connections are. However I think the connection is algae plant matter. See: http://www.jpl.nasa.gov/releases/2002/release_2002_54.html The Ross Sea is known for algae. Is Ross Sea algae very very cold? I think not. Although the following link is headed about the Arctic, scroll down to the image of the Ross Sea, Antarctica. Here: http://www.climatecentral.org/news/algae-accelerate-arctic-warming-18929 In that image I can see harmony or association between algae and clouds. I think a missing connection in climate science is nutrient and warmth associated with ocean and lake algae plant matter. Posted by JF Aus, Tuesday, 19 April 2016 8:59:37 AM

Climate change is happening; strategically something needs to be done to preserve infra-structure and assets. A number of times I have mentioned Miami as it is already bearing the impact of climate change. A further article on how Miami is being impacted: http://www.theguardian.com/environment/2016/apr/18/florida-wakes-climate-change Climate change is having an impact on Northern areas as well: http://www.aces.su.se/news/severe-arctic-ocean-acidification-via-permafrost-thawing-and-river-runoff In Australia coral bleaching is a major concern: http://www.smh.com.au/environment/sydneys-corals-now-bleaching-in-pretty-shocking-sign-of-warming-waters-20160418-go8qex.html#ixzz46BPoPuoI Down pours are a feature of climate change: http://wxshift.com/news/houston-underwater-from-torrential-rains?utm_content=bufferef185&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer What are the plans to try and adapt too, and mitigate against climate change?

I wrote nothing about green turtles starving, my comments were about turtle eggs being damaged by salt water and becoming unviable. To make it even clearer the number of hatchlings dropped significantly. You either missed the point; or, tried to divert the issue of non-viable green turtle eggs being damaged by salt water.
The David Attenborough series finishes next week, he will then be discussing what is causing damage to the reef.

Quite amusing in relation to your last reference in relation to James Hansen; the author, Eric Holthause writes a lot about climate change.
Here is an example:
http://www.rollingstone.com/politics/news/the-point-of-no-return-climate-change-nightmares-are-already-here-20150805
The first sentences say:
"Historians may look to 2015 as the year when ... really started hitting the fan. Some snapshots: In just the past few months, record-setting heat waves in Pakistan and India each killed more than 1,000 people. In Washington state's Olympic National Park, the rainforest caught fire for the first time in living memory."
In the reference I provided Ruth Mottram discusses Greenland where ice sheets have begun to melt very early.
First sentence from reference provided:
"An early melt event over the Greenland ice sheet occurred this week, smashing by a month the previous records of more than 10% of the ice sheet melting."
The climate is changing, whether mostly created by man; or, through natural causes. JF Aus pushes the growth of algae; but what is the plan to mitigate against it, Leo? Highways, sewage plants, storm waters; position of Hospitals, housing, farm land, and commercial centres become targets?
A photo of Miami is shown in the reference you provided, they already have fine day floods periodically in Miami when there are king tides.
In the future, I wonder who the criminals will be perceived to have been?
