Can anyone point out the errors of logic or fact in the following statement?

Question

Greenhouse gasses are only one element in the many factors that control our climate.

The main greenhouse gas is water vapour, accounting for about 95% of it.

The total CO2 accounts for only about 3% of the greenhouse effect.

The vast majority of the CO2 entering our atmosphere is caused by evaporation from the ocean, after that there is respiration, decomposition and volcanic eruptions. The total caused by human activity is only a minute fraction of the total CO2 entering our atmosphere.

So in short

Greenhouse gasses are only one part of the story

C02 is only a minor greenhouse gas

Human contribution to C02 is only fractional.

So how can man made CO2 be the main driving factor in our climate? Or if you believe the alarmists, it is the only factor.

Answer 1

I think that water pollution is a bigger problem than CO2. Burning of fossil fuels has also led to widespread respiratory heath problems, and a dependence on materials from unstable and unfriendly international trading partners. These factors are probably more of a threat to our well being than the millions of tons of CO2 we disperse into the atmosphere every year. While we may not be the primary factor in global warming, it would be wise to develop technologies that meet our needs with as little environmental impact as possible.

Answer 2

Well, for a start, water vapour is not a greenhouse gas.

Then, C02 emissions are not caused by simple 'evaporation of the sea.' Furthermore, the C02 produced by human activity is more than 'a minute fraction.' Plus, the amount doesn't matter so much as the additional burden represented by that amount- it is more than it should be.

To say that 'greenhouse gasses are only part of the story' is a blanket statement, no other factors have been brought up- and the term 'greenhouse gas' is never defined in this text. The lines that follow are conclusions with no solid base even within the text itself.

Answer 3

Water vapour certainly is a greenhouse gas. However, the amount of water vapour in the atmosphere depends only on the temperature of the atmosphere; there is therefore an equilibrium which is temperature dependent. When the earth cools, the concentration of water vapour falls through precipitation. Carbon dioxide is also dissolved in the oceans, and as the oceans warm, carbon dioxide is released into the atmosphere, causing further warming.

The difference with carbon dioxide is that carbon dioxide is being dug out of the ground and pumped into the atmosphere at a rate faster than than natural 'sinks' can absorb it. Carbon that was laid down over the course of hundreds of millions of years is being mined and expelled into the atmosphere in mere decades, a phenomenally fast rate. As a result, the concentration of carbon dioxide is steadily increasing, causing warming, which in turn causes the oceans to warm, more water vapour to be generated, in a positive cycle. The fact that water vapour accounts for over 90% of global warming only means that it is responsible for that percentage of the whole warmth of the earth bringing it above absolute zero, but the incremental warming is down to the activity of anthropogenic carbon dioxide, and that's the important part. That's why human generated carbon dioxide is driving climate change.

Answer 4

Observations: mainly your total state of affairs includes evil and that the existence of evil invalidates God. This has been stated advert nauseum for 100s of years. (a million) First, this is a God you've created and also you've were given restricted. as an get jointly, this would not be the God of Christianity because you left out countless key attributes, love, justice, and compassion. What you've is a truncated God. (3, 4) 2d, you're assuming that you comprehend God's values. for instance you anticipate that God values better than each little thing else battling evil and that it truly is the purely expression of goodness. i trust the finest suitable fee to God is love. There will be no love without such issues as freedom and decision. decision demands a minimum of two actual ideas. (3,4) 0.33, you're also assuming that omniscience and the plan of God may be the prevention of all a chance evil. enable's think that God reports time as "Now" Then for him the proper of evil has already occured and we are in eternity. this gained't be a part of the God you've created right here, yet transcendenc by the years is something that belongs to the Christian view of God. (5-8) You bounce from the existence of evil, to prevention of evil to culpabilty of evil. Culpability of evil belongs fullyyt to the guy doing the evil. it is what the Bible teaches. The soul that sins it is going to die.

Answer 5

The main greenhouse gas is water - that is true.

The CO2 concentration of the oceans is believed to be increasing. If that's true then more CO2 is entering the oceans than comming out of it and the oceans are a net sink - not a source.

Answer 6

Sounds like basic chemistry lesson. Combustion generates H2O and CO2 . Industry , transportation , energy consumption , landfills , deforestation ...etc, etc all add greenhouse gas and water vapour to the atmosphere on top of the nature cycle of carbon and water .
Maybe we add a little bit each day ....1 litre of petrol used add 2 kg of greenhouse gas....and it's tonnes per year !

Answer 7

Evaporation could never cause CO2 release. Where did you get that from?
CO2 is a fairly large part of the issue. Water vapor is of minor concern. Our production of CO2 is a definite problem. While our generation is not the only source of it, it is still something to consider doing something about.

Answer 8

<< Greenhouse gasses are only one element in the many factors that control our climate.>>

True, some of the factors play key roles, some play minor roles. The role of greenhouse gases is so vital that without them the planet would be dead. They're the process by which heat is retained in the atmopshere, no greenhouse gases and the planet is at -18°C (if you like, I can exlain the science behind the number).


<< The main greenhouse gas is water vapour, accounting for about 95% of it. >>

True and false. Water vapour is the main greenhouse gas by volume but it's very weak greenhouse gas, it has about one fourteenth the warming potential as carbon dioxide, and less than a thousandth that of nitrous oxide. The most potent greenhouse gas (sulphur hexaflouride) is more than 100,000 times as effective. It's not possible to assign a specific value to the contribution played by any of the gases because the contribution each makes overlaps, the total contribution made by water vapour to global warming is between 37 and 64%.


<< The total CO2 accounts for only about 3% of the greenhouse effect.>>

False. Due to the overlapping forcing mentioned above it's not possible to assign a value. What we do know is that of the gases emitted by huumans, CO2 is responsible for 72% of anthropogenic global warming. Human emissions have increased the amount of CO2 in the atmosphere by 38%.


<< The vast majority of the CO2 entering our atmosphere is caused by evaporation from the ocean, >>

Neither true nor false. The largest single contributor of CO2 are the oceans buit it's not the majority, it's a little under half of all emissions. Each year oceans emit 119 billion tons of CO2, but at the same time they absorb 120 billion tons so in all, they reduce the amount of CO2 in the atmoshere by 1 billion tons a year.


<< after that there is respiration, decomposition and volcanic eruptions. >>

False. After the oceans comes biomass then anthropogenic contributions. Biomass releases 88 billion tons of CO2 a year and absorbs 90 billion tons, all in all it removes 2 billion more tons that it produces. Humans emit 29 billion tons a year and absorb nil and herein lies the problem. The natural processes are in balance (they remove slightly more than they emit) but humans just emit gases and don't absorb them. Volcanoes emit about one third of a billion tons of CO2 each year, this is more than offset by their emissions of sulphur dioxide which causes more coolinng than the CO2 causes warming.


<< The total caused by human activity is only a minute fraction of the total CO2 entering our atmosphere.>>

False, for the reasons mentioned above. In all, nature removes more CO2 than it produces (it's a sink). 100% of the increase in atmospheric CO2 concentrations in recent centuries is due to human activities.


<< So in short, Greenhouse gasses are only one part of the story>>

True, but they're an essential part without which we'd be dead.


<< C02 is only a minor greenhouse gas >>

True and false, it's the primary contributor to the current warming trend but in terms of potency (not volume) then it's a weak gas.


<< Human contribution to C02 is only fractional.>>

False, as explained above, the natural processes remove more CO2 from the atmopshere than humans; humans only emit CO2. In short, we're overloading those natural processes almost 10 times over.


<< So how can man made CO2 be the main driving factor in our climate? >>

It's the main anthropogenic component, not the main driver.


<< Or if you believe the alarmists, it is the only factor.>>

No alarmist says that CO2 is the only factor.

Answer 9

The Earth is forever in a cycle of constant change It used to be hotter when the dinosaurs were around and you have also had the ice age who knows once the ice has melted in both poles it will cool down the seas especially the Atlantic conveyor belt which keeps the seas warmer on the west side of Britain if that stops flowing it could result in another ice age.
whatever happens humans will be like a cold for mother Earth eventually it will spit us all out, as Frazer would say from Dads Army were all doomed doomed doomed.
Having said this it will not stop me going down the pub tonight and enjoying a few beers cheers.

Answer 10

The answer to your question will depend on who you ask, and what axe they have to grind. As a species we are gathering more data on global warming almost by the hour, it's the projection of that data into accurate predictions that is impossible. Try googling Chaos theory, that will really mess with your mind, but it should tell you why only trends [hindsight] are accurate, predictions [ speculations] are only that.
