Norway is a shipping world power – so -  despite all the positive elements in the country – the masters of shipping do not want to be told to improve their fleet. We know what we say because we were involved years ago in the effort to see the UN make some sort of recommendation to have oil tankers obligated to be built with double hulls and compartments, so that in the case of a spill, not all the oil from a mega-barrel size ocean going monster end up on the beaches, on the fish, and the birds.

Brazil suggested the double hulls and compartments, Benin seconded, the G77 did not object in the UN Second Committee, but when it came to be added to the text – it was Norway that said NO! – and that was the end of it.

Now we see the following analysis of a very similar situation – the cleaning up of health endangering emissions from the burning of bunker fuel by ships and emissions of sulfur compounds – and we see that some scientists will say that the goo spewed out from the chimney of the ships is good for us because it helped in rejecting some sun rays after creating clouds. Other scientists will even tell us that there is the possibility of geo-engineering rains – just ask the Chinese that a couple of weeks ago managed to see destruction from floods they produced in ways suggested by these folks.

We wrote before, we love Norway but watch out when you step on their oil interests – that is when you find that they can be an OPEC auxiliary.

Curbs To Ship Pollution Would Stoke Global Warming, Study Says.

reported by Alister Doyle, Environment Correspondent, Reuters

November 23, 2009
OSLO – Shipping is slowing climate change by spewing out sunlight-dimming pollution but a clean-up needed to safeguard human health will stoke global warming, experts said Friday.

“So far shipping has caused a cooling effect that has slowed down global warming,” Jan Fuglestvedt, of the Center for International Climate and Environmental Research Oslo (CICERO), told Reuters.

“After some decades the net climate effect of shipping will shift from cooling to warming” because of cleaner fuels, he and colleagues in Germany, Britain and Norway wrote in this week’s edition of the journal Environmental Science and Technology.

Toxic sulphur dioxide emitted by burning bunker fuel accounted for the deaths of an estimated 60,000 people worldwide in 2001 through cancer and heart and lung disease, according to a previous study. A clean-up would save thousands of lives.

But sulphur pollution from the fast-growing shipping industry also helps create clouds by providing tiny seeds around which droplets form. Clouds have a cooling effect since sunlight bounces off their white tops.

The scientists argued against deliberate use of pollution from ships as part of possible schemes to shield the planet from sunlight, saying it was too risky and outweighed by the impact on human health.

CLIMATE COOLING

“The available evidence suggests that ‘climate cooling’ by continued shipping emissions of sulphur dioxide would not be advisable,” they wrote.

A clean-up of sulphur from ships will have a “double warming” effect — there will be more sunlight with less pollution and there will be ever more carbon dioxide, the non-toxic greenhouse gas emitted by burning fuel.

Shipping accounts for about 3.3 percent of world carbon dioxide emissions from human sources, emissions the U.N. Climate Panel says will cause more droughts, floods, heatwaves, rising sea levels and disease.

Some scientists, such as Nobel Prize winner Paul Crutzen, have suggested dumping sulphur in the upper atmosphere to slow global warming, one of several proposals for deliberate “geoengineering” to alter the climate system.

A U.N. climate summit in Copenhagen next month will consider new measures to penalize carbon dioxide emissions by both international shipping and aviation — both are outside the existing Kyoto Protocol for slowing emissions until 2012.

Fuglestvedt’s study estimated that it would take roughly 70 years for shipping to become a net contributor to global warming if sulphur dioxide emissions were quickly cut by 90 percent and all other fuel-related emissions stayed at 2000 levels.

The International Maritime Organization is seeking cuts in the sulphur content of bunker fuel to a maximum of 3.5 percent by 2012 and then to 0.5 percent by 2020.
