Ahh, global warming! I was refering to the few who made the news. Most, though are in the naive category, telling others that science supports their recomendation for humans to try and reduce their co2 production. Science does support carbon sequestration, in case the co2 matters, but is from more volcanos, or is from humans who can not be influenced culturally to change.

Over 95% of total CO2 emissions are natural. For example, the natural decay of organic material in forests and grasslands, such as dead trees, results in the release of about 220 gigatonnes of carbon dioxide every year. In 1997, Indonesian peat fires were estimated to have released between 13% and 40% of the average carbon emissions caused by the burning of fossil fuels around the world in a single year.[9][10][11] Although the initial carbon dioxide in the atmosphere of the young Earth was produced by volcanic activity, modern volcanic activity releases only 130 to 230 megatonnes of carbon dioxide each year,[12] which is less than 1% of the amount released by human activities.[13]
Cultures change over time, as their environment, including other cultures, influence them.

The wisdom of oceanic fertilization is disputed:

While many advocates of ocean iron fertilization see it as modern society's last best hope to slow global warming, a number of critics have also arisen including some academics, deep greens and proponents of competing technologies who cite a variety of concerns.
[edit]Precautionary principle
Main article: Precautionary principle
Critics apply the precautionary principle: the possible side effects of large-scale iron fertilization are not yet known; and that sufficient research has not yet been done. Significant, unknown, unforeseen, and unforeseeable risks may be involved. Creating blooms in naturally iron-poor areas of the ocean is like watering the desert: it is, in effect, completely changing one type of ecosystem into another. Critics argue that the risk of iron fertilization on the scale needed to affect global CO2 levels or animal populations is not an acceptable one.
An analogy can be drawn from this argument to systems theory which clearly indicates that there are always risks borne when any inexperienced "user" of a complex system goes "superuser", so to speak, and manipulates privileged channels without experience and knowledge of manipulation of such channels in a "production environment". The biosphere is a perfect example of this sort of system - it is incredibly complex, insufficiently documented, and absolutely vital. In the event that iron fertilization - or any manipulation of privileged channels in the biosphere through large scale geoengineering measures - results in unintended consequences, there may be no methods of reversal.
While advocates argue that iron addition would help to reverse a supposed decline in phytoplankton, this decline may not be real. One study (Gregg and Conkright, 2002) reported a decline in ocean productivity between the period 1979–1986 and 1997–2000[37], but another study (Antoine et al.., 2005) found a 22% increase between 1979–1986 and 1998–2002. Gregg et al.. 2005 also reported a recent increase in phytoplankton.

Fertilization advocates respond that similar algal blooms have occurred naturally for millions of years with no observed ill effects. The Azolla event occurred around 49 million years ago and accomplished what fertilization is intended to achieve (but on a larger scale). Not even trying to remedy industrial impacts is far more irresponsible considering the known pace of increasing harm.
[edit]Inadequacies
According to certain ocean iron fertilization trial reports, this approach may actually sequester very little carbon per bloom, with most of the plankton being eaten rather than deposited on the ocean floor, and thus require too many seeding voyages to be practical.[14][38]
The counter-argument to this is that the low sequestration estimates that emerged from some ocean trials are largely due to three factors:[citation needed]
Timing: none of the ocean trials had enough boat time to monitor their blooms for more than 27 days, and all their measurements are confined to those early weeks. Blooms generally last 60–90 days with the heaviest precipitation occurring during the last two months.
Scale: most trials used less than 1000 kg of iron and thus created small blooms that were quickly devoured by opportunistic zooplankton, krill, and fish that swarmed into the seeded region.
Academic conservatism: having an obviously limited data set and unique sequestration criteria (see Sequestration Definitions below), many peer-reviewed ocean researchers are understandably reluctant to project or speculate upon the results their experiments might have actually achieved during the full course of a bloom.
Some ocean trials did indeed report remarkable results. According to IronEx II reports, their thousand kilogram iron contribution to the equatorial Pacific generated a carbonaceous biomass equivalent to one hundred full-grown redwoods within the first two weeks. Researchers on Wegener Institute's 2004 Eifex experiment recorded carbon dioxide to iron fixation ratios of nearly 300,000 to 1.
Current estimates of the amount of iron required to restore all the lost plankton and sequester 3 gigatons/year of CO2 range widely, from approximately two hundred thousand tons/year to over 4 million tons/year. Even in the latter worst case scenario, this only represents about 16 supertanker loads of iron and a projected cost of less than €20 billion ($27 Billion). Considering EU penalties for Kyoto non-compliance will reach €100/ton CO2e ($135/ton CO2e) in 2010 and the annual value of the global carbon credit market is projected to exceed €1 trillion by 2012, even the most conservative estimate still portrays a very feasible and inexpensive strategy to offset half of all industrial emissions.[citation needed]
[edit]Sequestration definitions
Critics note that in ocean science, carbon is not considered removed from the system unless it settles to the ocean floor where it is truly sequestered for eons. Most of the carbon that sinks beneath plankton blooms is dissolved and remineralized at well above the seafloor and will eventually be re-released to the atmosphere, negating the original effect.
Advocates argue that even though ocean science does traditionally define "sequestration" in terms of sea floor sediment, modern climate scientists and Kyoto Protocol policy makers define sequestration in much shorter time frames. For example, they recognize trees and grasslands as important carbon sinks. Forest biomass only sequesters carbon for decades, but carbon that sinks below the marine thermocline (100–200 meters) is effectively removed from the atmosphere for hundreds of years, whether it is remineralized or not. Since deep ocean currents take so long to resurface, their carbon content is effectively "sequestered" by any terrestrial criterion in use today.
[edit]Ecological issues
[edit]Harmful Algal Blooms (HAB)
Main article: Harmful algal bloom
A "red tide" off the coast of La Jolla, San Diego, California.
Critics are concerned that fertilization will create a harmful algal bloom. It is not known what kind of plankton will bloom after fertilization. Some plankton species cause red tides and other toxic phenomena. What will prevent toxic species from poisoning lagoons, tide pools and other sensitive costal ecosystems? Once a HAB gets started, no one knows how to end it. Despite the unfavorable cold water, the red tide in Maine over the last three years is evidence of this. In addition, even when harmless species of plankton die they decompose. This creates a situation like the giant (and growing) dead zone in the Gulf of Mexico.[citation needed]
Fertilization advocates claim that most species of phytoplankton are entirely harmless, and indeed beneficial. Red tides and other harmful algal blooms are largely coastal phenomena which primarily affect creatures that eat contaminated coastal shellfish. Iron stimulated plankton blooms are only relevant in the deep oceans where iron deficiency is the problem. Most coastal waters are replete with iron and adding more has no useful effect. Since phytoplankton blooms in the open ocean last only 90–120 days, fertilized patches of any species will dissipate long before reaching costal waters.[citation needed]
[edit]Deep water oxygen depletion
When organic bloom detritus sinks into the abyss, a significant fraction will be devoured by bacteria, other microorganisms and deep sea animals which also consume oxygen. Critics are concerned that a large bloom could, therefore, render certain regions of the sea deep beneath it anoxic and threaten other benthic species.[citation needed]
However, advocates argue that the largest plankton replenishment projects now being proposed are less than 10% the size of most natural wind-fed blooms. In the wake of major dust storms, many extremely vast natural blooms have been studied since the beginning of the 20th century and no such deep water dieoffs have ever been reported.[citation needed]
[edit]Ecosystem alterations
Depending upon the composition and timing of delivery, critics argue that these iron infusions could preferentially favor certain species and alter surface ecosystems to unknown effect. Population explosions of jellyfish, disturbance of the food chain with a huge impact on whale populations or fisheries are cited as potential dangers.[citation needed] A 2010 study shows that iron enrichment stimulates toxic diatom production in high-nitrate, low-chlorophyll areas [1], which, the authors argue, raises "serious concerns over the net benefit and sustainability of large-scale iron fertilizations".
Advocates argue that CO2-induced surface water heating and rising carbonic acidity are already shifting population distributions for phytoplankton, zooplankton and many other creatures on a massive scale.[citation needed]
If certain infusions or space/time coordinates do show asymmetrical selective impacts in certain regions, the effect is inherently constrained by the limited size and 90-day lifespan of each bloom. Only larger scale research will show if this is really a problem, what factors alter the ecosystem, and whether this issue can be effectively addressed.
[edit]Conclusion and further research
Advocates say that using this technique to restore ocean plankton to recent known levels of health would help solve half the climate change problem, revive major fisheries and cetacean populations, and alleviate several other urgent ocean crises.[citation needed] Critics say global warming must be solved at the source, large scale iron fertilization experiments have never been attempted, the effects could be inadequate, and too little is known to press ahead.[citation needed]
Critics and advocates generally agree that most outstanding questions on the impact, safety and efficacy of ocean iron fertilization can only be answered by much larger studies. One pilot project planned by a U.S. company called Planktos[39] was cancelled in 2008 after it was unable to secure funding, a situation that the company blamed environmental organisations for.[40][41]
A 2009 Indo-German team of scientists examined the potential of the south-western Atlantic to sequester significant amounts of carbon dioxide, but found few positive results.[42]
I actually travelled on the ship that performed this experiment a few months later.

As I read the papers, the phoney scientists happily blend all these. Confusion is fusing together things that need analysis, not synthesis.
But the well meaning dishonesty didn't help.
Why should the separate these phenomena, which are deeply connected to one another?

The system is, there is in our ecosystem what is found in the ecosystem of every other species we know of, other living forms that are epistemologically more sophisticated. More senses, bigger brain, more intellectual possibilities, greater vocabulary. One of these beings has an ethological interest in us, and has devised a means of communication with us. He has sent us a "book" like our other books, but in this case a guide book to this means of communication.
Are you saying that there are many species with more sophisticated brains, intellects etc. than others, there must be one with a superior intellect etc than us?
Must there not therefore be a species or entity more powerful than god and the devil, and another one more powerful than it etc? Why stop the chain of more powerful entities one step above us?

The first thing I heard was that the devil is out to make a fool out of all humans, because humans are made in the image of God, look loke God, and when that image is defiled, God is dishonored. The second thing had to do with who is in charge of earth. The devil likes to be in charge of the earth, to cause it to be ugly, because it belongs to God, who "loves" the world. Like putting trash on someone's yard. Humans like to make things beautiful, at times. So, Making humans dysfunctional in earth stewardship is a big agenda item. There are many others, but you get the point, and if you trully want to know, you'll take up the necessary study to find out for yourself.
If god cares so much about humans and the earth, why does he reveal his instructions and warnings only in ways that are indistinguishable from people making up this god for their own purposes or because they are schizophrenic? What kind of defilements of the image of god do you have in mind?

I find this plausible because I did many experiments with the prayer, "Deliver us from the evil one." and watched many situations change.
Most situations change without prayer too.
