Thread: How Much Do You Know About Climate Change?...A Quiz.

Your theoretical 9 acres of trees would soak up your carbon emissions continuously, no need to plant more every year. I'd imagine that you would harvest mature timber and bury the waste instead of burning it to maximise your carbon into the soil. Dunno what burning does to the carbon balance. The method of working out how much carbon stays put in your soil is complex.

Where does charcoal, or black carbon, in soils go?

I got 100%, but only because I answered q1 wrong.

I've studied ice core samples, and although the climate has stabilised to what it was in the past, just like a ripple getting smaller in a pond, we still see the qarming and cooling cycles of the past. currently we are overdue for a warning cycle.
But. ...what we find according to the ice core data is that this warming cycle is happening a lot quicker than any time in observable history.

Slaps forehead, I should've seen that I wouldn't need to plant annually (better leave the math's homework to my wife). Though, I gather mature trees take up less carbon than new growth, so I'd probably need to plant a few 9 acre plots throughout my life.

Heard someone on ABC radio today banging on about trees being part of the solution to take up carbon in the air. But?

An acre of trees takes up 2(ish) tonnes of carbon per year (roughly).
'I' use 17 tonnes of carbon per year (roughly - according to Wikipedia).

So I'd need to plant 9 acres of trees per year just to cover my usage. Those trees need water etc. Then, when they die, they release the carbon anyway, unless i turn them into furniture or books.

How much carbon is stored in asphalt? Couldn't we just make more roads? Or make asphalt and dump it to the bottom of the ocean?

No you only have to plant them once the trees will convert CO2 all the life of the tree. Yes when the tree dies carbon will be released via burning or decomposition, but no where near what was converted during the life of the tree.

If the pollies were really worried about this they would limit population growth, it is the elephant in the room.

The biggest problem with that as I see it is that what happens when the existing population ages? We are already seeing the issues this is causing the welfare system. Imagine if you had net zero population growth - in a few generations the average age would be dramatically higher with a lower number of the working population trying to support them.

I don't disagree we have too many people on the planet, but slowing the growth down would have many long reaching implications.

I don't know what the answer is - cataclysmic weather events to wipe 100's of millions out? That's the way it will probably go eventually - Mother Nature will intervene and restore the balance.

Yes, it seems that is why China has had to relax its one child policy.

Finding solutions to problems is easy. Finding solutions that don't create other problems is more difficult.

I got 6 out of 9, one was a hit the wrong one by mistake one was couldn't remember whether it was 2025 or 2030 as the target and the other I had no clue.

My opinion on Climate change is, yes I know it's happening and yes we are affecting it in some way, and yes we need address it, but I also think that most of the change is due to the planets natural cycle, will us reversing what we have done, help slow the planets natural cycle, assuming our affect has sped it up, I have no idea.

I know one thing for sure, Australia isn't doing enough compared to the rest of the world.
