Answer 1

put a bunch of plants up there? Plants remove it naturally by photosynthesis and replace it with O2. Is having too much CO2 a bad thing, really? I would rather think that Carbon MONOxide would be worse...

Answer 2

Forrest remove excess carbon dioxide
in the autumn rotting vegetation poduces a lot and the cold waters absorb it ,so water plays a big part in removing carbon ,but in the spring when new growth requires it the warmer waters release it
the best constant absorbing factor is bio mass
and that is getting less with overpopulation and the carbon production is much bigger and increasing because of harmfull habits causing airpolution,and Industry ,and Nature has a bigger job to do all the time ,because of de forestation and we have reached critical levels
to counter act this we must plant vegetation especially trees where ever possible especially i populated areas ,such as suburbs and outside the cities
agro forestal which means farming mixed with trees is a solution being preached world wide and the world bank has programs to plant and reforrest with trees like Pawlonia which are especially suited for absorbing carbon as well as producing animal food

Answer 3

This CO2 thing is nonsense. 97% of CO2 is caused by the evaporation of the Earth's oceans. Humans create only 3%.

The argument then becomes, we have upset the balance of nature. This is more nonsense. Earth, and even the universe, is in constant flux a systematic chaos.

We measure change of our planet in tens or hundreds of thousands of years, not a century. Since the end of the last full ice age, we are now dead on the average temperature.

In fact, it has been 7 degrees warmer to 7 degrees colder on average than where we find ourselves now.

To see how manipulated this is, everyone needs to understand that there was a Little Ice Age, between the end of the 1300's and approximately 1850. Of course the average temperature of Earth, is going to be warmer as measured against that time period.

For approximately 800 years before the Little Ice Age, the was a significant warming trend, that was 3 to 4 degrees higher than where we are now.

It was during this time that the Vikings discovered, are you ready for this Greenland. It was green and they were able to cultivate the land. HELLO? ANY ONE HOME?

This indicates a warming well in excess of where we are now, or would be in 100 years, since worst-case scenario is that we will rise .7 degrees centigrade.

Why such a warming? It was the last significant period when the sun's radiation was high. We have been entering such a period for the last 50 years. HELLO? WE ARE WARMER BECAUSE OF THE SUN'S OUTPUT. As are Mars, Venus, Mercury, etc., ect., etc. The last I checked, white men with AC hadn't invaded those planets yet.

This whole global warming baloney is being manipulated to destroy America's system, our economy and our preeminent place as leader of the free world. For what, jealousy pure and simple.

Answer 4

Kansan is wrong. The little ice age and the relatively mild weather before it were not global events. These alterations in temperature were confined to about 2500 sqaure miles, mostly affecting Europe.

What we are now facing is global warming, not European warming. What Kansan is talking abot isn't even climate, it's weather.

The periods of warmth, around 900-1300 AD and the cooler weather that followed were probably attributable to relatively minor alterations in ocean currents, the so called mexican current in particular. Global warming will have a huge impact on these currents, resulting in catastrophic climate change all over Europe.

As to the figures of 7 degrees higher or lower, does Kansan mean C or F?

Assume that mankind can live in temps 7 degrees F higher and 7 degees F lower than we have today. That means that our species ony has a 14 degree temperature range in which it can live. How wise is it then, to not worry about global warming?

Answer 5

Massive sheets of carbon paper, and an almost superhuman faith in the idea that like attracts like.
That's the carbon taken care of.
Now for those pesky dioxides...
Well, they're just oxygen, aren't they?
And, seeing as oxygen is the new miracle ingredient in all the trendier washing powders, sell it off to the makers of New Blam! Now with added Oxygen for an even cleaner clean! (This imaginary clothing detergent product has been brought to you by the Imaginary Product Marketing Board, please pay scant attention, it's okay, they're only imaginary...).
I just thought you might appreciate a completely non-scientific and silly answer, as a bit of a change.
