Fact:  the earth's climate has been constantly changing for the last 4.5 billion years as the link I posted indicates.

 

Fact: the amount of CO2 in the atmosphere is the highest it has ever been recorded and human activity  ( carbon burning ) is a the major factor in the increase..

 

Fact: increased CO2 in the atmosphere increases heat retention..

 

It is the ultimate in hubris to believe that if human carbon burning reductions cannot have the power to effect any significant change, since it was human activity over the last 100years that was the major cause of the increase of CO2 in the atmosphere.

Guys, Trudeau has got this! He can control the climate and put money in your pocket!

What percentage of atmospheric gases is CO2?

[Tony]

Yes CO2 represents only a small part of the atmospheric gases. Most atmospheric gases have no effect on the greenhouse gas effect.

 

 The gasses that do affect the greenhouse gas effect are the most important gases to monitor even though they represent a small percent of the atmosphere.

 

Here is one simple brief explanation of the effect of these greenhouse gases that only represent a small but critical percent of the atmosphere.

What percentage of the atmosphere is CO2, do you think? Just off the top of your head, if you’d like.

[Nparker]

Carbon dioxide occurs naturally in small amounts (about 0.04 percent) in the Earth's atmosphere. Carbon dioxide is a minor part of the air that humans breathe.

0.04%. Tony says that’s “a small part.” It is, in fact, hardly detectable at all. Thank of it like a hundred cups full of water. The co2 is in the 101th cup, that has just barely a noticeable volume of liquid in it (about 10ml, compared to 25,000ml).

Back the heyday of the dinosaurs, CO2 levels were about 20x higher, archaeological records show.

I don’t know what the answers are. I don’t even know what questions to really ask. But what I do know, is our governments cannot solve whatever crises they think they can, if they cannot solve issues facing the most basic of human needs.

[Nparker]

Zealotry and excessive taxation are most definitely not the answers.

[Mike K.]

Not when the climate advocates are spending their time online all day. Server farms produce astonishingly high volumes of c02 emissions, to power the online communications or social networks we don’t give a second thought to. The sheer volume of energy required to sustain these networks is absolutely mind boggling.

85,000 people flew into Dubai to attend the 2023 climate conference. This sort of cognitive dissonance/hypocrisy is all I need to know about the "crisis".

[Tony]

All human related sources of greenhouse gases are part of the problem and part of the solution since those are the only sources that humans can change.

 

The millions of years of cyclical changes will continue since they are not human caused.

 

Current levels of CO2 in the atmosphere is about 419 ppm. with the most rapid rise since the 19 century. The highest previously recorded levels  in 100s of thousands of years of past cyclical changes is about 300 ppm.

 

Increased CO2 levels and other greenhouse gases means more retained heat and that retained heat affects the climate in addition to the natural cycles.

[Mike K.]

Don’t plants breath co2?

[Victoria Watcher]

The plants want more CO2 bad.

[Tony]

Increasing CO2 levels in greenhouses can increase production. 340 to 1,000 ppm. is optimum for many plants. Lots of greenhouses increase their CO2 levels inside for this reason.

 

If the required CO2 level monitoring system fails and too much is put in, at high enough levels it will kill people. and have negative effects on plant growth in an enclosed greenhouse environment..

[JimV]

We should also remember that the minimum that can support life is about 150ppm.  Below that photosynthesis stops and everything that depends on oxygen dies.

 

Current level is about 420ppm (not actually that far from the minimum.)  If a CO2 molecule were a person this would amount to the capacity of two large condo buildings compared to the entire population of Vancouver Island.  The annual human caused increase would be a couple extra residents every few years.  Scary.

How much is a ton of carbon dioxide?

Imagine a cube 27 feet tall, wide, and long. But just in case that’s a little hard to picture, imagine a cube almost as tall, wide, and long as a telephone pole. That’s how much space it would take to hold a metric ton of CO2.

 

And remember, this is literally a ton. While it may not seem like a gas can weigh that much, this 27’ x 27’ x 27’ cube has the same weight as a great white shark or, well, a ton of bricks (400 bricks!)

 

The average North American produces enough CO2 each year to fill 15 of these enormous cubes. This many cubes can fill over three Olympic-sized swimming pools. The Earth is able to reabsorb a lot of that CO2 through trees, oceans, and other natural processes. But much of it will stay in the atmosphere, potentially for hundreds of years.

And Canada's climate will improve drastically, and we will become the new go to place for winter vacations, I'm in.

[Tony]

How can we produce that many tons of CO2?   How can a gas weigh so much?

 

A liter of gasoline weighs about 750grams and when used in an engine produces about 2.2kg of CO2. How can there be more weight of CO2 than the original weight of the gasoline?

 

A liter of gasoline  weighs about 750 grams. 640grams of the weight of the gasoline is Carbon. In the engine combustion process all the Carbon combines with 2 units of oxygen from the air. Each Oxygen unit  from the air weighs 800grams. (2x800grams ) and  that combines with the 640 grams of Carbon to produce CO2 that weighs a total of 2.2kg.  (Carbon dioxide has two units of Oxygen for each unit of Carbon.)

 

So burning 1 liter of gasoline that has 640grams of carbon from the gasoline and 1600grams  of Oxygen from the air produces a total weight of about 2.2kg of CO2.
