Do you think lowering carbon levels, could actually cause global warming?

Question

The scentists have said that when the temperature rises, that pine trees emit more carbon, do you think this is Mother natures way of controling the temp. , by placing more carbon in the atmostphere and possiblity blocked the rays of the sun from heating the palnet, I know this may be out there, but what if we actually caused global warming by reducing carbon levels, or could we, say we reduced the levels and mother nature sensing this ,started producing more carbon

Answer 1

CO2 levels are not all that significant.

Answer 2

plants use co2 to grow.  The more co2 the more they grow, locking away the co2 and thus removing it from the atmosphere.  

We add too much, and they cant handle it all, and thus the green house effect of warming will result.

Answer 3

As the temperature rises, more green vegetation will exist on earth for some time. Eventually a limit will be reached and the the increase in vegetation will slow down. As more vegetation exists on the surface of the earth, more CO2 will be used up in photosynthesis. Once again, this two will level out eventually.

I assume by "we" you mean human induced climate change. I'll give you MY opinion based on my current studies at school. Climate change is occurring naturally, with or without human influence. The great debate today is whether or not humans are influencing climate change. Which yes, we are.

I'm currently studying my third year at Queen's University in physical geography, and this semester am taking another course entitled: "Climate Change".  It's based off of the IPCC's fourth assessment report. With this being said, I have never heard personally of "scientists" saying that as the temperature rises, pine trees will emit more carbon. Do you have a source for this so I could check it out?

Also, CO2 in the atmosphere doesn't block out solar radiation. I can provide further explanation on this if you like.

Answer 4

I doubt it, but I have noticed that all the DENIER/skeptic arguments require disregarding differences of scale entirely.

Answer 5

No.  Carbon dioxide is a greenhouse gas, meaning it absorbs heat.  It doesn't block sunlight.  Further details at the link below.

Answer 6

In every "global warming" event in the past, rise in CO2 levels trailed rise in temperature.  CO2 levels peaked after temperatures fell from their highs....you may be on to something there.  Good thing man will never get organized enough to affect our own CO2 output, much less the world's existing balance of CO2.

Answer 7

No.

The effect of vegetation on CO2 is way less than our inputs.  You can see it clearly here:

The little squiggles are nature doing its' thing. CO2 falls a bit during summer when plants are active, and rises during the winter. The huge increase is us, burning fossil fuels. The scientists can actually show that the increased CO2 in the air comes from burning fossil fuels by using "isotopic ratios" to identify that CO2.

Man is upsetting the balance of nature.  We need to fix that.

Answer 8

No, that's the opposite of what's happened in the past.  Increasing carbon dioxide is associated with increasing temperatures.

Besides, carbon does not block the sun's incoming energy as you claim.  It does block outgoing heat (infrared radiation), which is why increased temperatures at night, which have been observed, are a concern.  It's one of the signs that the increased carbon dioxide is trapping more heat and global warming is present.

As for trees, they absorb carbon dioxide, store the carbon, and release oxygen.  That's why people plant trees to reduce global warming.
