global warming?

Question

if global warming is caused by more carbon dioxide being released into the atmosphere than that which can be removed from the atmosphere by photosynthesis, has proportion of carbon dioxide dioxide in the atmosphere increased in a measure of ppm or percentage relative to the other gaseous components in the atmosphere over the past 150 years, if so by how much.

Answer 1

Yes. Prior to the industrial revolution, the level of CO2 in the air was stable at about 280 ppmv (parts per million by volume). Currently the level of CO2 is 383 ppmv, and increasing exponentially with no end in sight.

Therefore the increase in CO2 in the air since 1800 currently stands at about 37%.

Answer 2

It's not.

Your question is flawed. 1st, you have to believe that the increase in temperature is a result of increased carbon emissions.

Its the increase in temperature that results in the increase in carbon emissions. The ocean is the greatest contributor to carbon emissions. The warmer the ocean becomes, the greater the amount of carbon dioxide being released into the atmosphere, The cooler the ocean is, will cause less.

So the question then becomes... Why are the oceans getting warmer? Answer is Simple: THE SUN

Maybe some of you Hysterical Nut Cases and the IPCC can arrange a mission to the Sun and confront the issue head on at the source. Take Al Gore with you. Oh don't worry you'll be safe, go during the night.

Answer 3

I don't have to hand the figures for the last 150 years but from my own research can give you the figures for the last 250 years...

Carbon dioxide has increased from 278 to 384ppmv (38% increase), this is by far the most prevelant of the greenhouse gases (GHGs) accounting for more than 99% of all GHGs by volume.

The other primary GHGs have also increased in concentration - methane from 700 to 1792ppbv (256% increase), nitrous oxide from 270 to 318ppbv (18% increase) and tetraflouromethane from 40pptv to 80pptv (100% increase).

There are two other primary GHGs (those contributing more than 0.1% to total global warming), both are synthetic - dichlorodiflouromethane has increased from 0pptv to 533pptv and trichloroflouromethane has increased from 0 pptv to 268pptv.

Levels of the 'natural' gases such as nitrogen, helium, argon and oxygen have remained within the range of natural variation.

Levels of other 'manmade' gases that do not contribute to global warming as such, have also increased, gases such as sulphur dioxide, hydrogen sulphide and carbon monoxide.

(Side note - levels of SO2 and some other gases fluctuate widely and a year on year comparison would be unreliable, data used was a 25 year mean).

Answer 4

It's all speculation. We don't really know. The same way we don't know what caused the ice age. Still it's a good excuse to charge us more for oil and gas, and a way to make us sort out our own rubbish before the council dump it all in a landfill.

The way I look at it is that the ice age caused the water to freeze and now it is starting to defrost, and probably has been for thousands of years. We just had no way of knowing.

Trying to predict the course of nature based on 150 years of statistics when the earth is millions of years old is like trying to work out if a 3 year old is going to be a genius by observing him for 5 seconds.

Answer 5

good question. I don't think we really know. because of the perceived importance of global warming information caused by Al Gore, we are probably keeping a careful watch on the atmosphere now, but maybe not so much prior to this. Now there are so many zealots who have taken up this cause that we are going to be inundated with information, some good ,some not so good. I can't wait to hear them, regarding the recent wildfires across the country. Let me go on record as being the first to predict that many of these fires will be found to have been started by these very same zealots.

Answer 6

The present atmospheric concentration of CO2 is about 383 parts per million (ppm) by volume.Future CO2 levels are expected to rise due to ongoing burning of fossil fuels and land-use change. The rate of rise will depend on uncertain economic, sociological, technological, natural developments, but may be ultimately limited by the availability of fossil fuels. The IPCC Special Report on Emissions Scenarios gives a wide range of future CO2 scenarios, ranging from 541 to 970 ppm by the year 2100. Fossil fuel reserves are sufficient to reach this level and continue emissions past 2100, if coal, tar sands or methane clathrates are extensively used.
Positive feedback effects such as the expected release of CH4 from the melting of permafrost peat bogs in Siberia (possibly up to 70,000 million tonnes) may lead to significant additional sources of greenhouse gas emissions not included in climate models cited by the IPCC

Answer 7

hi dear i think u should know that the ratio of carbon dioxide doesnt increase in span of 100 years it increase in very long span of time now the percentage of carbon dioxide is near by 0.03% photisynthesis is the one mear by which carbon is consumed but there are many way by which it is consumed
do u know that more than 50% of carbn dioxide is consumed by forests near amozon basin it is said that if it would be cut than carbon will in crease in much proportion but if such a thing took place carbon dioxide is not only responsible for global warming but the most resposibe gas fo it is carbon monoxide which is CO

Answer 8

Meteorologist Dr. Reid Bryson, the founding chairman of the Department of Meteorology at University of Wisconsin (now the Department of Oceanic and Atmospheric Sciences, was pivotal in promoting the coming ice age scare of the 1970’s ( See Time Magazine’s 1974 article “Another Ice Age” citing Bryson: & see Newsweek’s 1975 article “The Cooling World” citing Bryson) has now converted into a leading global warming skeptic. In February 8, 2007 Bryson dismissed what he terms "sky is falling" man-made global warming fears. Bryson, was on the United Nations Global 500 Roll of Honor and was identified by the British Institute of Geographers as the most frequently cited climatologist in the world. “Before there were enough people to make any difference at all, two million years ago, nobody was changing the climate, yet the climate was changing, okay?”


Environmental geochemist Dr. Jan Veizer, professor emeritus of University of Ottawa, converted from believer to skeptic after conducting scientific studies of climate history. “I simply accepted the (global warming) theory as given,” Veizer wrote on April 30, 2007 about predictions that increasing C02 in the atmosphere was leading to a climate catastrophe. “The final conversion came when I realized that the solar/cosmic ray connection gave far more consistent picture with climate, over many time scales, than did the CO2 scenario,” Veizer wrote. “It was the results of my work on past records, on geological time scales, that led me to realize the discrepancies with empirical observations. Trying to understand the background issues of modeling led to realization of the assumptions and uncertainties involved,” Veizer explained. “The past record strongly favors the solar/cosmic alternative as the principal climate driver,”

Answer 9

We should make artificial lighting to increase the ozone amount into the atmosphere,and release hydrogen from the ocean waters to form more rain.

Answer 10

315 ppmv in 1958, 377 ppmv in 2004

carbon dioxide is not the only "greenhouse gas". methane (CH4) has 4x the potential effect as CO2.
