Pakistan navy and Saudi Navy Naseem Al Bahr X




 The current commander of the RSNF, Vice Admiral Dakheel-Allah Bin Ahmad Bin Mohammad Al-Wakadani, is also a graduate of Pakistan Naval Academy and reserves a special place for his alma mater.

The RSNF has now come of age and taken its rightful place in guarding the maritime interests of KSA. Despite its exposure to naval exercises with the most advanced navies of the world, the RSNF holds PN in high esteem. Naseem Al Bahar (NAB) is a biennial exercise, which was evolved as manifestation of the unique Pak-Saudi interpersonal relationship and mutual resolve to enhance bilateral cooperation in facing the common challenges.

Scheduled from January 12 to 22, 2013, the joint exercise is not merely based on physical manoeuvres of various surface, aerial and sub-surface naval platforms, but involve the entire gamut of maritime operations; planning, executing and drawing lessons from NAB-X

Philippine Coast Guard to receive 10 patrol boats from Japan


 
MANILA, Philippines–The Philippine Coast Guard is set to hire some 300 new personnel to man 10 new patrol boats expected to arrive from Japan.
PCG spokesman Commander Armand Balilo said they would prioritize applicants who would fit the qualifications of those who will man the new acquisitions.

“We need to recruit people with maritime-related courses such as marine engineers and marine navigation course. But we would also be needing technical experts such as those who have mechanical, welding and electrical skills or background,” said Balilo.
Foreign Affairs Secretary Albert Del Rosario discussed with Japanese Foreign Minister Fumio Kishida, during the latter’s visit early this week, a loan agreement for the Philippines’ procurement of 10 multi-role response vessels for the Coast Guard.

The new patrol vessels, which are expected to arrive in 2014, are expected to boost the country’s territorial defense in the West Philippine Sea.
PCG usually accepts applicants who finished even non-maritime-related courses.
“But we should now prepare for our new assets. We should prepare the right people or the crew and asset management team who would be in charge of our new vessels’ maintenance,” Balilo explained.
He added that they have one year to hire the needed personnel, who would be assigned for deck operation, navigation, gunnery and engineering.

Those who would be selected would undergo one-year training on board the new ships.

President Obama, here's a climate plan!


President Obama, now is the time to act on climate change! Climate change won't wait. There are encouraging signs indicating that a summit is being organized, to be hosted at the White House, to launch a comprehensive climate action plan with broad-based and bipartisan support.

What plan? Well, here's a climate plan!



The first line of action of most climate plans is to cut emissions. Two types of feebates, working separately, yet complimentary, can cut emissions most effectively and can be implemented locally in a budget-neutral way, without requiring complicated international agreements:
  1. energy feebates (pictured above) in sectors such as electricity, heating and transport, and 
  2. feebates in sectors such as agriculture, land use, waste management and construction (pictured below).
Pictured on the left are feebates that impose fees on sales of Portland cement, nitrogen fertilizers and livestock products. This will make further cuts in emissions.

The revenues are then used to fund rebates on clean construction and on soil supplements containing biochar and olive sand, which will remove carbon dioxide from the atmosphere and store it in buildings, soil, river banks, roads and pavement.

Working seperately, yet complimentary, energy feebates and feebates in agriculture and other sectors can dramatically bring down carbon dioxide levels in the atmosphere and oceans; as a result, atmospheric carbon dioxide could be brought back to pre-industral levels of around 280ppm by the end of the century.

For further discussion, also see Towards a Sustainable Economy
Thus, these two feebates will be effective on two lines of action, i.e. on cutting emissions and on reducing carbon dioxide levels in the atmosphere and oceans.

Even with these measures, temperatures will keep rising for some time, as excess ocean heat will get transferred to the atmosphere over the years and as aerosols (particularly sulfur) fall away that are currently emitted when fuel is burned and thus mask the full wrath of global warming.

Continued warming comes with numerous feedbacks. Combined, these feedbacks threaten to trigger runaway global warming, i.e. warming that will cause mass death, destruction and extinction.

How to avoid mass-scale death, destruction and extinction
This means that, in addition to the first two lines of action, further lines of action will be necessary, i.e. Solar radiation management, and Methane management and further action. Further action includes regulatory measures such as ending commercial flights over the Arctic and support for pyrolysis to avoid burning of biomass. The image below pictures several methods of Arctic methane management that should get high priority, given the threat of hydrate destabilization in the Arctic.
Arctic Methane Management

Fees imposed on commercial flights could fund solar radiation management, while the feebates described above will also be most effective in further lines of action, i.e. in Arctic methane management and further action.

Dark Snow Project - Research into soot on Greenland

Fossil fuel combustion creates carbon emissions that increase atmospheric thickness, warming climate. The occurrence of wildfire increases with climate warming, increasing soot loading of the atmosphere. Some of this soot is transported through the atmosphere and is deposited on glaciers, lowering their reflectivity, increasing solar energy absorption, increasing melt rates.

In parts of Greenland where winter snow loss during each melt season exposes impurity-rich bare ice, the surface reflectivity drops from 85% to 30%. Consequently, most of the 24-hour sunlight goes into ice melt. In this Dark Zone, the impact of soot manifests strongest in a self-reinforcing feedback loop that research by Jason Box has shown to have doubled melt rates in the past decade.

High on the inland ice sheet where melting is rare, satellite data show surface darkening making the researchers suspect that wildfire and industrial soot are to blame. Darkening here promotes snowpack heating, bringing earlier melt, keeping melt going longer. Here is where this feedback is changing the ice sheet in surprising ways, leading to complete surface melting in year 2012.



To measure the extent to which soot particles enhance melting, Jason Box is organizing a Greenland ice sheet expedition for 2013. The Dark Snow Project expedition is to be the first of its kind, made possible by crowd-source funding.

Anthropogenic Arctic Volcano can calm climate

by Paul Beckwith
Paul Beckwith, B.Eng, M.Sc. (Physics),
Ph.D. student (Climatology) and
Part-time Professor, University of Ottawa
 

Rational decision making requires realistic risk assessments of alternatives. Humanity is now choosing default door A, which is no change in behavior with fossil fuel energy sourcing and a continuance of rapidly rising anthropogenic greenhouse gas emissions (GHGs).

Abrupt collapse of Arctic albedo due to collapsing terrestrial snow cover (area dropping 17.6% per decade for past three decades) and collapse of sea ice cover (area dropping 49% below 1979 to 2000 long term average) is occurring (NOAA 2012 Arctic Report Card from last week).

The destination is an ice free condition within a few years (by 2015 with PIOMAS volume projections); well before the 30 to 60 year timeframe of the most sophisticated climate change models which are a big FAIL on sea ice. The risk (= probability of occurrence x significance of occurrence) is enormous through door A. Probability of occurrence is 50% within 3 years and significance to human farming, water availability, temperatures and weather extremes is clearly massive.

A recent widely-respected DARA report states that Today climate change is directly/indirectly reducing global GDP by 1.6% and attributing to 400,000 human deaths globally (to increase to 2.6% and 500,000 in about 20 years). A recent UN report is warning of global food shortages in 2013. There is no end in sight to the U.S. drought (climate models predict such droughts can last 20 or 30 years, hopefully they are wrong as they are with sea ice).

I prefer door B - create an Anthropogenic Arctic volcano to calm the climate. Give me two large airplanes with pilots, some sulfur in solution, and a few large nozzles from your local ski hill; they are not needed anyway since the ski industry has estimated losses of $1 Billion over the last decade (about 8% of total revenues); adaptation to zip lining and water parks is possible. With this equipment I will fly into the stratosphere (above the weather) near the North Pole and spread sulfur dust/aerosols to reflect incoming sunlight and rapidly cool the Arctic for several years. This will restore sea ice, straighten the jet streams, and restore a “normal” climate.

Very little sulfur is needed relative to huge emissions from smokestacks into the lower atmosphere from coal burning power plants. It will work; powerful erupting volcanoes that aim upwards (like Pinatubo in 1991) and not sideways (like Mt. St. Helens in 1980) have cooled the climate by a degree or more for 2 to 3 years. They do this by injecting sulfur up into the upper atmosphere, like our aircraft will do.

Door B has two important sub-doors, B-Bad and B-Good. Door B-B is using the sulfur injections to calm climate and continuing the fossil-fuel energy sourcing with rapidly accelerating GHGs. This door will be a false reprieve since the GHGs will continue to rapidly acidify the ocean and destroy the base of the food chain; by the way, ocean phytoplankton levels have dropped 40% since 1950.

Wikipedia image: UN jet with humanitarian relief supplies
Luckily for us, Door B-G exists. Door B-G is using the sulfur injections to calm climate and rapidly slashing fossil-fuel energy sourcing by ramping up conservation, efficiency renewables as fast as is humanly possible; I am talking about retooling on the scale of the Manhattan Project or Apollo Programs. Or even having a U.S. president (or a Chinese one) getting all the CEOs of car manufacturers together in a room and telling them they will produce no cars for 3 years, only wind turbines, geothermal heat exchangers, and solar panels. Is this possible? In WWII the meeting occurred and for the next 3 years only war materials were produced. And keep in mind the industrial revolution of World War Two ushered in one of longest eras of prosperity humanity has known.

Of course there is a caveat with Door B-G. We must start the sulfur injections when the sun rises in the Arctic in the spring in early 2013. Waiting for more sea ice collapse will decrease the odds of success at obtaining Arctic snow cover and sea ice regrowth. Give me a plane, pilot, nozzle, and sulfur and I can calm the climate.

Russia’s defense steps up in aerospace missiles

After shutting down production of the S-300 missile defense system, Russia is moving to equip its new S-400 and S-500 systems with hypersonic missiles. A shortage of more advanced missiles, however, stands in the way of the Ministry of Defense’s plans.


Russia is planning to open two major plants to produce much-needed advanced hypersonic missiles, but experts suggest that the country will be unable to counter a massive NATO attack for the next 10 years.

By 2014, Russia will launch two major plants to produce the 77N6-N and 77N6-N1 hypersonic missiles for its state-of-the-art anti-missile defense systems – S-400 “Triumph” and S-500 “Prometheus.”

The Ministry of Defense has officially announced that, “with these missiles, surface-to-air missile systems will be able to bring down any target flying at a speed of up to 7 kilometers per second, including nuclear warheads of ballistic missiles.”
The S-500 system has yet to be completed, while its S-400 predecessor can currently launch the older 48N6 and 9M96 missiles.

The 77N6-N and 77N6-N1 models will be the first Russian missiles with inert warheads, which can destroy nuclear warheads by force of impact (i.e., by hitting them with precision at great speed). No explosives are needed: engineers’ estimates show that a collision at a speed of 7 kilometers (4.3 miles) per second would be sure to destroy just about any flying object.

The new plants are vital for the development of an anti-missile shield above Russia, since new surface-to-air systems are already entering service unequipped with new missiles.
For now, the “Triumph” (S-400) defense system is complete with missiles that have been left over from the old S-300 systems. Their range is around 124 miles, whereas the S-400s are designed to intercept targets at a distance of about 250 miles.
The absence of more advanced missiles stands in the way of fully equipping Russia’s Air Forces and Aerospace Defense Forces with the S-400 systems. Only seven divisions have been supplied with such systems since 2007, with another 49 waiting to receive them, according to official data.
The missile shortage became even worse after production of the old S-300 systems was halted completely.
“The last S-300 was produced for the Russian army in 1994 or so,” says Igor Ashurbeili, co-chairman of an expert council on aerospace defense and former chief designer at the Russian defense company Almaz-Antey. “Since then, Russia has only produced these systems for sale. But now even export orders for the S-300s have been suspended.”
Indeed, Moscow turned down a contract with Iran back in 2010, losing $800 million. Production was completely shut down after rolling out the last S-300 division intended for export, which is to be supplied to Algeria soon. One of the problems faced by the Russian defense industry is that it stopped accepting orders for the S-300s, but has not started to take orders for the S-400s, says Ashurbeili.
The design of S-400 missiles has not been completed either. The system should be fully compatible with short-, medium- and long-range missiles. Presently, however, only short-range missiles intended for hitting targets within 95 miles have been designed without problems. Medium-range missiles (up to 155 miles) are still “raw,” and their design needs to be finalized.

The long-range missiles are non-existent, even though such a missile would be a serious hindrance to potential enemy vehicles, including Airborne Warning and Control Systems (AWACS). Without these missiles, the S-400 cannot fulfill its purpose – engaging targets at a long range.
As for the future S-500 system, it will be an S-400 with long-range missiles, according to Alexanderf Khramchikhin, deputy director of the Institute for Political and Military Analysis.

“The S-500s will at best be created in 2020 – no earlier. At present, and for the next 10 years, the chances of countering a massive NATO attack are very low: it takes a long time to recharge the S-300s, so, in the best case, they will only repel the first wave of an assault, which would be 100 to 200 targets,” says Khramchikhin.

Military expert Vladislav Shurygin agrees with Khramchikhin. “For now, the S-500 is an ephemeral dream, and no one knows if it will ever come true,” he said. 
Even though the S-300s need to be replaced, there is simply no replacement for them. This is why Almaz-Antey is faced with some very important tasks. “Handling them will determine the future not only of the anti-missile defense system, but also of the country as a whole,” says Shurygin. The company is still capable of manufacturing high-quality products, but it needs to modernize its technologies and refurbish its production facilities quickly.

In other words, the production of modern aerospace defense weaponry is a comprehensive task which requires major technological innovations and modernization of existing production facilities.
