Jennifer Marohasy, thank you for reply. Unlike a lot of people you have the courage to investigate to learn.

There are 26 six years of satellite observations and temperature-driven melt models, indicating for example:
Atmospheric temperatures have been important in forcing runoff.
There has been a record trend of increasing runoff since the mid 1980’s and in situ marine temperatures followed equivalent trend.
http://geology.gsapubs.org/content/40/12/1095.abstract

I think dead algae can be a cause of dark snow and decrease in reflectivity, impacting albedo measurement and solar heated melt of polar ice.
I think winds blow sea surface nutrient matter and dried matter on coastlines, including dead algae matter, up onto Arctic ice. Wind blows up heavy sand that builds islands (e.g. Moreton Island).

Snow algae also requires more nutrient than from sunlight alone.

Nutrient including in far north Atlantic waters is not just due to runoff.
It is the total nutrient loading from all sources, natural and human.
It is nutrient overload-pollution that should be focus of great concern especially because it is linked to increase in ocean dead zones.

Blooming algae mirrors the springtime thaw:
(Copied and pasted) Credit: European Space Agency.
Each spring, huge patches of phytoplankton bloom in the oceans, turning cold, blue waters into teeming green pools of microbial life. This ocean “greening,” which can be seen from space, mirrors the springtime thaw on land. But while spring arrives gradually on land, with a few blades here and some buds there, the oceans bloom seemingly overnight.

Marine ecosystems govern the way the marine environment works.

Algae is increasing at unprecedented rates.
If it was sunlight alone proliferating algae then the entire sunlit Pacific Ocean would be inundated with algae, but it is not.
In general Pacific Ocean open offshore waters are a clear blue with very good visibility underwater.

Northern Atlantic and Arctic waters. Windfinder. Note dominant wind direction for the year is northwards.

Seaweed is a colloquial name for algae and phytoplankton. Sargassum seaweed/algae is increasing in mass and distribution from the north Atlantic to Barbados and across the massive Atlantic Ocean to Sierra Leone.

Northerly predominant seabreeze and stronger winds in the Atlantic north of the equator blow over solar-warmed surface-floating sargassum algae and must pick up available warmth and have a warming effect in the Arctic region.
Increase in sargassum coincides with increase in temperature at Greenland and Iceland.

Sargassum is an emerging issue. Massive quantities. Impacting resources.
http://sero.nmfs.noaa.gov/habitat_conservation/documents/pdfs/hcd_pdf/gcfisargassumfactsheet_2015.pdf

Sargassum is a macro algae, the green of Caribbean waters is chlorophyll in common micro algae.

I think sewage and land use nutrient overload is causing increase in sargassum and other algae and the increase is causing increase in intensity of weather and melt of Arctic ice.

Water warmed in algae inundated waters sits higher than colder water sea level. N.B the centre of the southerly streaming warm East Australian Current.

Pacific Ocean ecosystems where human sewage and land use nutrient overload has to be expected includes coastal waters of Mexico, Panama, Columbia, Ecuador and Peru where El Nino phenomena begins.
There is historically unprecedented algae and impact and damage causing ‘canary in the coal mine’ evidence of potential to lose world food supply security. Even aquaculture is being impacted.
http://undark.org/2016/03/08/chiles-salmon-industry-strangled-algae/

Wind drives surface ocean surface water including fresher water with bonded nutrient.
Dominant wind direction near the coast of Peru is northwards – toward the equator where El Nino phenomena occurs before moving westward.

If complete data relevant to any of the above is required before action is taken to prevent further damage to the environment and economies then science should collect that data. N.B The Precautionary Principle.
There is no data to prove formation of gravity. That does not mean gravity does not exist.

Solutions include multi-billion dollar water management infrastructure for the Murray Darling Basin - Coorong ecosystems.

I rarely talk about algae blooms.
However I talk often about algae. That's because over-abundance of common green algae and destructive epiphyte growth on seagrass is different to a bloom.
So I talk about algae in general.
I don't post on every thread and every subject as you do, ant. And good luck to you, I am not objecting.

What do you know about horses and carts?
Think more about hitching the horse before the cart.
I suggest leave selection of the horse and the cart until the load and incline and distance to be travelled is measured and assessed and known.
e.g. begin to comprehend by assessing my post in reply to JM.

The lesson at the link you posted is quite full of holes. Where is the evidence?
Where is evidence warming is caused by CO2 prior to any algae occurring?

And where is your evidence, ant, that algae has no relationship with warmth and melt of ice as you seem to believe?

I think being a CO2 believer can be a handicap in honest non-biased thinking about climate change.

Yes there are areas where sea level is lower and others where it is higher. Tides come to mind.
Why is such a huge volume of melted ice water not spreading out globally with equal sea level rise globally?

Science has been using vessel engine water intakes to measure ocean temperature. Genuine science is now aware engine intakes are positioned as low as possible in hulls to take up the coldest water available to cool engines.
I think satellites provide the best and most reliable ocean surface temperature data.

I cannot comment about cause of grass fires you refer to, ant.

Yes I state my opinion on this site called Online Opinion.

I do not claim to be providing proof but I do provide evidence of substance, such as to JM, and you ant have never been able to provide any evidence whatsoever to disprove it

Jennifer Marohasy,

I find it interesting to understand how much meteorology knows about algae and warmth in algae and influence of ocean and lake algae on weather.

The link below should help with some of the scientific evidence you seek.

Note, algae from the sea can become airborne, as I suggested a few days ago in my post re dark snow in Greenland.
And:
A good correlation has been found between algae and prevailing weather conditions, season and time of day.

Jennifer,

N.B. Nutrient pollution and algae - example of extent of it.

The perfect storm they say, but no city or town sewage dumping mentioned, just private septic tanks, farmers costly fertilizer, and stormwater with innocent pet owner's dog droppings. LOL

It's the total nutrient loading feeding algae and warming areas of ocean and seas and lakes. The total loading.
Government and the UN re oceans must shoulder responsibility.

Jennifer Marohasy,

Nutrient pollution, a key to the jigsaw.
http://www.environment.no/topics/marine-and-coastal-waters/eutrophication/

I consider this report from the Norwegian Environment Agency to be very fair and honest.
Most other reports only point to farmers and stormwater for nutrient runoff.
