The main greenhouse gases have reached their highest levels recorded since per-industrial times, according to the world meteorological organization's 2009 greenhouse gas bulletin (pdf) the report also highlights concerns that global warming may lead to even greater emissions of methane from arctic. Many people today have serious concerns about greenhouse gases and the impact they have on the environment although some deny that human activity has anything to do with changing climate conditions, evidence strongly suggests that greenhouse gases are largely to blame for recent weather and. Climate change is primarily a problem of too much carbon dioxide (co2) in the atmosphere this carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests there are many heat-trapping gases (from methane to water vapor), but co2 puts us at the. The concern about the greenhouse effect arises because human activities are currently raising atmospheric concentrations of greenhouse gases and threatening in this paper, i will translate all impacts and costs into a common unit, the co2 equivalent of ghg emissions, measured in terms of the carbon content of co2.
We all have to reduce our co2 emissions in order to protect our planet factors affecting climate change besides the enhanced greenhouse effect there are it is of concern because it is driven by human activity • greenhouse gases are gases present in the atmosphere which trap the sun's energy • there are many of. What is climate change and why should we be concerned about it david adam explains only an increased greenhouse effect caused by higher amounts of heat-trapping gases in the atmosphere can explain it what is the main carbon dioxide is the chief greenhouse gas produced by human activity. The worst of this summer's searing heat may be over, but the concerns that it raised about a global warming trend - known as the greenhouse effect - seem ''how do you get attention focused on more diverse issues like energy efficiency, when you're sitting at a table with nuclear people who say, 'here,. The atmospheric variables that drive climate and weather are solar energy, humidity, precipitation, atmospheric pressure, and wind currents it is very important that you clearly understand the difference between the two, so for a more detailed discussion, go to the nasa website (click here) figure 3 atmosphere structure.
Greenhouse gases are necessary to life as we know it, because they keep the planet's surface warmer than it otherwise would be but, as the concentrations of these gases continue to increase in the atmosphere, the earth's temperature is climbing above past levels. Surprisingly, the concern of physical and biological scientists has not called forth a similar level of concern from policy analysts' since it is now evident that the issues require policy analysis, i predict that they will receive a good deal more attention in the future greenhouse effects have the attributes of being (1) global ( in. You might hear people talking about the greenhouse effect as if it is a bad thing it is not a bad thing, but people are concerned because earth's 'greenhouse' is warming up very rapidly this is happening because we are currently adding more greenhouse gases to our atmosphere, causing an increased greenhouse effect. Carbon dioxide is the greenhouse gas of most immediate concern, because it is the most concentrated in the atmosphere and because it can persist for over 100 as we continue to burn fossil fuels and cut down our forests (which are carbon storage facilities) we both add directly to global warming and accelerate the.
A secondary school revision resource for gcse geography on climate change and the greenhouse effect when fossil fuels are burned - by industry, in power stations and by vehicles and planes - gases (as unwanted by-products known as carbon emissions) enter the atmosphere carbon dioxide (co2), in particular,. The greenhouse effect occurs when earth's atmosphere traps solar radiation because of the presence of certain gases, which causes temperatures to rise i think that measuring with precision human activity on the climate is something very challenging to do, and there's tremendous disagreement about. How does this warming compare to previous changes in earth's climate how can we be certain that human-released greenhouse gases are causing the warming how much more will the earth warm how will earth respond answering these questions is perhaps the most significant scientific challenge of our time.
The trend over decades is what we should focus on what's even more worrisome, he explained, is that air temperatures only give part of the picture the real concern with the buildup of greenhouse gases is that “we're getting more energy from the sun than we're sending back into space,” he said. To address your main concern though, co2 in the upper atmosphere: eh, not a huge concern, potentially even beneficial co2 in the lower atmosphere: contributes to the greenhouse effect to be any more specific than that you really have to look at the absorption spectrum of co2 and the emittance spectrum of the earth. When greenhouse gas concentrations are high, they absorb a greater percentage of the earth's infrared energy emissions this means that more energy gets and that human activities are causing it as far as scientists are concerned, there is no debate about whether climate change is real, or whether we are causing it.
Climate scientists often blame the greenhouse effect for contributing to earth's environmental woes, but it has a vital positive effect on the planet as well extreme effects one of the chief concerns about an increase in the greenhouse effect is that the changes can become self-sustaining as more. Without the greenhouse effect we would be living in a very chilly place—the world's average temperature would be minus 18°c, instead of the 15°c we are while scientists agree that the levels of greenhouse gases and average global temperatures are rising, there is less certainty about what the future. We do know that carbon dioxide is a greenhouse gas greenhouse gases act as a blanket over the earth when sunlight heats the earth's surface, the warm earth radiates some of that heat into the atmosphere greenhouse gases slow the escape of that radiated heat you have been led to believe that the. If you are 10 years old, you have lived through at least five of the six years that have been hottest across the globe since record-keeping began such greenhouse gases are released every time someone burns fossil fuels (such as coal, oil or gas) to drive a car, to heat or cool a building or to run some.
