Climate Change: Why Australia needs to do NOTHING!
Dec 24^th, 2019 at 8:49am

Australia's eco system sequesters more CO2 every year than Australia emits, therefore we are a carbon neutral country, what we emit is taken up by our land and its eco system.

Here are some crude results from what information is available.

Depending on their state like, tree spacing, humidity, dryness etc etc
Australian grasslands and forests sequester approximately between
0.5 to 2 tonnes of carbon per hectare annually

To convert to CO2 we need to multiply by 3.67, therefore re-writing

Australian grasslands and forests sequester approximately between
1.835 to 7.34 tonnes of carbon dioxide per hectare annually

There are approximately 149 million hectares of Australian forests
There are approximately 440 million hectares of Australia grass lands

Forrest uptake of atmospheric CO2 every year
Lowest: 149 x 1.835 = 273.4 million tonnes of CO2 per annum
Highest: 149 x 7.34 = 1093.66 million tonnes of CO2 per annum

Grasslands uptake of atmospheric CO2 every year
Lowest: 440 x 1.835 = 807.4 million tonnes of CO2 per annum
Highest: 440 x 7.34 = 3229.6 million tonnes of CO2 per annum

Let’s combine grasslands and forest uptake of atmospheric CO2 per annum
Lowest: 273.4 + 807.4 = 1080.8 million tonnes of CO2 per annum
Highest: 1093.66 + 3229.6 = 4323.26 million tonnes per annum

Australia emits 560 million tonnes of CO2 per annum

The bottom line is
Lowest: Our grasslands and forests sequester nearly double what we emit.
Highest: Our grass lands and forests sequester nearly eight times more than we emit.

Conclusion:

It would be a rare occasion for the lowest or the highest values to take place therefore more than likely we would hover somewhere in between lowest and highest depending on the sun and weather conditions.

The above doesn't take into account the uptake of the land (Australian soil) itself which would make those values even bigger.

Soil can sequester carbon at the following rates

Croplands…………………………………………………..0.25 to 1.0 tonnes of carbon per hectare annually
Pastures………………………………………………………0.1 to 0.175 tonnes of carbon per hectare annually
Permanent crops…………………………………………0.5 to 1.0 tonnes of carbon per hectare annually
Salt affected & chemically degrade soil………0.3 to 0.7 tonnes of carbon per hectare annually
Physically degraded & prone water erosion….0.2 to 0.5 tonnes of carbon per hectare annually
Susceptible to wind erosion………………………..0.05 to 0.2 tonnes of carbon per hectare annually

Multiply by 3.67 to convert to CO2

Croplands…………………………………………………..0.918 to 3.67 tonnes of CO2 per hectare annually
Pastures………………………………………………………0.367 to 0.6423 tonnes of CO2 per hectare annually
Permanent crops…………………………………………1.835 to 3.67 tonnes of tonnes of CO2 per hectare annually
Salt affected & chemically degrade soil………1.101 to 2.569 tonnes of tonnes of CO2 per hectare annually
Physically degraded & prone water erosion….0.734 to 01.835 tonnes of tonnes of CO2 per hectare annually
Susceptible to wind erosion………………………..0.1835 to 0.734 tonnes of tonnes of CO2 per hectare annually

Australian land area = 769.2 million hectares

Instead of trying to do the calcs and sorting out what percentage is crop land, pastures etc, I got lazy and refer you to this,

This paper by (Cf Barret 2002) estimated CO2 exchange between atmosphere and the Australian soil at 700 million tonnes every year.

Therefore it can be said that just the Australian land soil sequestration of CO2 from our atmosphere is greater than Australia’s CO2 emissions.

.........................560 < 700.

If we do go to market for an Emission Trading Scheme we shouldn't pay anything at all, after all we are carbon neutral.

In fact we can sell the extra (sink capacity) as carbon derivatives.

But hey I wouldn't really want to go there.

Death to the oligarchy controlled United Nations and all their schemes......... Cheesy

If nuclear energy wasn't as dangerous as it is I would agree with you, remember Chernobyl.

As for hydrogen cars you will be sitting on a bomb not unlike LPG cylinders, because they are pressurized.

I'll address Ajax and PZ here.

Modern Nukes are safe. Chernobyl was the result of inherent design flaws due to design cost cutting and the incompetence of Soviet regime safety regulations.

Hydrogen cars: both Kia and Toyota are gearing up for hydrogen cars. It's going to happen.

Hydrogen is no more or less dangerous than other flammable fuels, including gasoline and natural gas. In fact, some of hydrogen's differences actually provide safety benefits compared to gasoline or other fuels. However, all flammable fuels must be handled responsibly.

Another take:

Now that you know about the dangers of hydrogen as a fuel source, should you be terrified by the prospect of having a tank full of it in your car? Not necessarily. Because hydrogen gas is so light, it disperses rapidly, mixing with the surrounding air and rapidly rising through it. Although pure hydrogen ignites quite easily, in reality, this diluted hydrogen mixture is no more likely to catch fire than gasoline is. And because it rises it isn't likely to remain near the ground, where it's most likely to harm people.

not sure WE as humans need not to do any more ajax..

we! us humans have got very complacent..take far too much for granted the stuff we throw away these days is causing no end of trouble...[ and we think Nuclear waste is a problem] have you taken a look in the bins your send out once a week to collections....thats just "you" imagine every home office shop restaurant Roll Eyes

its mind boggling.....we take rubbish pick up for granted we dont give it another thought... totally reckless....

this time of the year we kind double up if not treble up on everything....

we can do better and we should be better...

recycling doesnt seem to be the answer part maybe but not all ...

we must do better...why cant our rubbish be turned into fuel for instance..

all we seem to do is make more[i] toys for grown ups that can be thrown away every 6 months.. Sad

Faulty logic Ajax

Why haven't you included natural CO₂ emissions in your equation?
Natural emissions roughly equal natural absorption
Human emissions are ADDITIONAL emissions

You deniers seem to have a blind spot when it comes to the carbon cycle

No petal. Natural emissions are not anthropogenic.
Remember what the satellite showed? Australia was a net carbon sink. And that was despite your faulty logic of conflating two years of anthro emissions into one. Grin

All the data showed is that you were able to cherry pick a year after major bushfires 2010
That proves nothing
