What evidence indicates that the rising atmospheric carbon dioxide levels are caused by the combustion of fossil fuels?
the average global temp and the atmospheric co2 level has risen
Carbon dioxide in a sentence?
The carbon Dioxide levels in the Earth's atmosphere are rising.
How will an increase in carbon dioxide most likely affect earth?
Carbon dioxide is a greenhouse gas that in normal concentrations helps keep the earth at a comfortable temperature, suitable for human existence. Scientists tell us that the increase in the atmospheric concentration of carbon dioxide since pre-industrial times has been accompanied by a gradual increase in average global temperatures. They warn that the rate of increase is rising rapidly and will result in extreme global warming and climate change unless we reduce our carbon dioxide emissions.
How do oceans decrease the amount of atmospheric carbon dioxide?
As the atmospheric concentration of carbon dioxide increases above its long-term average level, the surface water of the oceans begins to absorb more carbon dioxide from the atmosphere, thereby partly countering the addition of carbon dioxide to the atmosphere. This is demonstrated by the rising acidity of sea water, since dissolved carbon dioxide becomes carbonic acid. However, there is very little interchange of water between the warm surface layer and the deep ocean, so very little of this carbon dioxide is dispersed into deeper water. Scientists say that the anthropogenic increase in atmospheric carbon dioxide level could be absorbed by the ocean, but only over a period of several thousand years.
Can you see carbon dioxide rising from fire?
Nope - the gas is colourless !
Can plants absorb the excess carbon in the atmosphere?
A:In a natural balance, plants absorb as much carbon dioxide (CO2) as animals exhale, keeping the concentration of atmospheric carbon dioxide at the long-term average of around 260 to 280 parts per million (ppm). Human activities have increased this level to 380 ppm since the beginning of the Industrial Revolution, and rising fat. This itself is evidence that plants simply can not absorb the additional carbon dioxide load in the atmosphere. Moreover, our continuing destruction of forests actually reduces the ability of plants to absorb carbon dioxide, and is one important reason for the rising CO2 levels.

How has the greenhouse effect been improved?
Unfortunately the enhanced greenhouse effect has not improved. Carbon dioxide and methane levels are continuing to rise, with the rise in carbon dioxide levels actually rising at an exponential rate. The one small piece of good news is that methane levels are currently rising at a much slower rate than they had been. There is hope that we can also slow the rise in the concentration of atmospheric carbon dioxide, but only if we as individuals do more, and our governments develop the political courage to take the action they know must sooner or later be taken.
How do forests affect the temperature?
Forests (and all vegetation) remove carbon dioxide from the atmosphere. This reduces the effects of the enhanced greenhouse effect, slowing the rising temperatures of global warming.
Is the earth's rising atmospheric temperature caused by man's energy consumption?
Yes, partly. The earth is globally warming because of the build up of greenhouse gases, mostly carbon dioxide, in the atmosphere.Deforestation, the destruction of forests, means the trees no longer reove carbon dioxide from the air.Man's energy consumption is fuelled by the burning of coal, oil and natural gas. This burning releases carbon dioxide.Transport and industry also burn oil.All these things cause the earth's rising temperature.
Is the concentration of atmospheric carbon dioxide currently decreasing due to human activities?
No, the concentration is actually rising. We are burning too much fossil fuels (coal, oil and natural gas), and we are cutting down too many forests.
Is there a limit that the existing atmosphere cannot sustain life because of to much carbon dioxide?
Yes, but the upper maximum for atmospheric carbon dioxide sustaining life is pretty high. The more interesting question is, what is the upper maximum for atmospheric carbon dioxide that is compatible with sustaining human life - this is probably somewhere in the range of 500-600 ppm. We are currently at about 393 ppm and the concentration is still rising rapidly.Prior to the rise of land animals, there was an explosion of plants that evolved and took advantage of a very high atmospheric carbon dioxide concentration. When these plants originally evolved, it took a great deal of time for the pathogens and saprophytes to evolve the ability to break them back down. The resulting accumulations of carbon-rich material in the sedimentary layers of the earth, from these plants that died and were not broken down and recycled, is where humans are now deriving fossil fuels (crude oil, natural gas) from.
