A Brief History of CO2-Related Climate Change

So, pretty soon, all we'll have to do is 'bubble' the air through water to create our own fizzy "carbonated" drinks (wink,wink)? ! ? !

Maybe the answer for removing CO₂ is Algae. They manufacture themselves and convert CO2 to algel oil which can be used to manufacture carbon fiber, a strong and light building material. This carbon will be removed from the atmosphere for a long time as opposed to carbon turned into plastic which will reenter the atmosphere when the plastic is incinerated.

"In collaboration with fellow researchers, chemists at the Technical University of Munich (TUM) have developed a process that, according to initial calculations, can facilitate economically removing the greenhouse gas carbon dioxide from the atmosphere. "

"Algae convert carbon dioxide from the atmosphere, power plants or steel processing exhaust into algae oil. In a subsequent step, this is then used to produce valuable carbon fibers – economically, as initial analyses show."

If we started using carbon fiber for building material it would certainly help...of course we would need new fastening systems for carbon fiber it seems....then again maybe not....

...certainly car frames and bodies...

From your link: 'The new understanding was incorporated in the IPCC's 2014 report, which warned, "Surface temperatures will remain approximately constant at elevated levels for many centuries after a complete cessation of anthropogenic CO2 emissions." Whatever we did now, humanity was already committed to centuries of violently changing weather and rising seas, followed by millennia in the new, heated state.'

Is this your conclusion? If so, what is the point of making cars out of carbon fibre?

Something that is seldom factored in is the advance of technology. We can do things now that were undreamed of not that long ago, and I suspect in the future we will do things that are impractical today.

We don't know what we don't know.

No reason to believe this is not true, and that it will continue to be the case.....change is the one thing we can be sure of....

Climate change is not a hoax. It is real. Global climate change caused by mankind is a hoax. Water vapor and CO2 have about the same thermal insulating factor. But, water vapor averages about 40 to 60 times more than CO2 in the atmosphere. The effect of CO2 is minuscule compared to water vapor. CO2 could increase 10 times and it would not make any difference, because that is not what causes the temperature to rise.

The sun spews out charged atomic particles call the solar wind. You can see the effects of these particles called the Northern and Southern Lights near the poles. The interstellar cosmos bombards the Earth with cosmic rays. You can see their condensation tracks in a Wilson Cloud Chamber. The cosmic rays help to condense the water vapor in the atmosphere into clouds, which in turn shield the Earth from the heat of the sun, thereby making the Earth cooler. When the sun is highly active, the solar wind together with the magnetic field of the Earth, repels the cosmic rays away from the Earth, thereby making it warmer.

The increase in CO2 is caused by the increase in the Earth's temperature, which causes the release of CO2 from the sea and other places. The CO2 increase is an effect, not a cause.

Those of you who are old enough can remember when most of the northern hemisphere was covered in a ice cap. Back then there was no man made CO2 generation. But, the solar cycle eventually changed and the ice cap melted. So, you can go ahead and buy all the carbo-credits you want; it will not change things. Only if you can manipulate the sun can you change Earth's global climate.

I guess you couldn't take time to read the article explaining how we have come to these beliefs....and the scientific research behind it...I know it's a bit of a long read, but it has been a long journey....

Worldwide, we are currently pulling about 80 million barrels of oil a day from the ground. That's a figure from 2010, so today it may be more or less.

Now calculate the amount of carbon in that oil. From what I gather from the web, it's about 112kg of carbon at the low end. Most crude will have more. Multiply that out by the 80 million.

8,960,000,000 kg

That's the amount of carbon in that 80 million barrels. Now say that half of that is used in plastics, solvents, fertilizers, etc. that is not released into the atmosphere. That's still over 4 billion kilograms of carbon per day that was previously sequestered, for millions of years, underground.

That's a lot to expect of algae, switch grass or trees to absorb.

..."In the carbon cycle diagram above, there are two sets of numbers. The black numbers are the size, in gigatonnes of carbon (GtC), of the box. The purple numbers are the fluxes (or rate of flow) to and from a box in gigatonnes of carbon per year (Gt/y).

A little quick counting shows that about 200 Gt C leaves and enters the atmosphere each year. As a first approximation then, given the reservoir size of 750 Gt, we can work out that the residence time of a given molecule of CO2 is 750 Gt C / 200 Gt C y-1 = about 3-4 years. (However, careful counting up of the sources (supply) and sinks (removal) shows that there is a net imbalance; carbon in the atmosphere is increasing by about 3.3 Gt per year)."...

1 Gt = 1,000,000,000,000 kg.

..."coal with a carbon content of 78 percent and a heating value of 14,000 Btu per pound emits about 204.3 pounds of carbon dioxide per million Btu when completely burned. Complete combustion of 1 short ton (2,000 pounds) of this coal will generate about 5,720 pounds (2.86 short tons) of carbon dioxide."...

...we can ballpark it at 700 million tonnes of coal times 2.86 = roughly 2 bil tonnes of CO₂ per year... or 2 Gt

..."High carbon dioxide producing activities include: Consuming electricity: Burning fossil fuels emits CO2, with coal releasing twice as much of the gas as petroleum. Worldwide, fossil fuels generate 85 percent of electricity. ... Currently, 41 percent of CO2 emissions in the U.S. arise from generating electricity."...

...as you can see from the figures, it's quite do-able....it sounds like a lot, and quite frankly it is, but taken in the context of scale, not as much as you might think...Population growth and developing economies are fighting us every inch of the way though...and it doesn't look like this trend will level off anytime soon...Developing countries don't have the means of the developed nations to make as much impact on the global CO₂ balance as we can...The United States as a global leader in energy use per capita is destined to lead the way in a journey that will span centuries....so no need to panic, no need to take drastic measures, just slow steady change....If we could double nuclear and renewable generation we could eliminate coal altogether....that would be nearly 90% of yearly added CO₂ imbalance...

We need to open up the Yucca mountain storage site, start reprocessing high level nuclear waste, and streamline nuclear power regulations....continue the rollout of electric vehicles and charging stations....

more CO2 means an increase in plant life. More plant life means more oxygen.

Lots of investors lost lots of money in the 2000's due to the whole "algae to oil" BS. in fact, the venture capitalist that usually invest in early stage tech were so guy shy that they pretty much knocked back the research to Fuel cells as well as other emerging technologies by more than 10 yrs.

An interesting fact to the whole man made global warming tax scheme is that the temperature on mars has followed the same curve as earth during the same time frame.

hmmm could it be the sun that is causing the earth to warm??? a novel hypothesis.

"more CO2 means an increase in plant life. More plant life means more oxygen."

No. Read post #7. The CO₂ absorption rate of plants is far lower than the rate that we are releasing it into the atmosphere. Keep in mind that it took millions of years to sequester the carbon that we have released in recent history, i.e. the last 100-150 years.

"temperature on mars has followed the same curve as earth during the same time frame."

Can you cite any sources confirming temperature measurements on Mars?

Its a good religion I guess. kinda like the whole "fate" thing. if we throw a bunch of money towards global cooling then when the cycle turns down, we then cured the earths temperature.

Did you notice that at glacier national park they removed the signs? There were signs that told people to take pictures now because the glaciers were going to be gone by 2020. Well in the last couple of years the glaciers the glaciers have increased.

imagine if the world would go into another ice age (like the "scientists" predicted back in the 70's), I bet we wouldn't be worrying about how much fossil fuel we burned would we.
