  1. You&#039;re in the right box.


  2. carbon dioxide and other gasses like methane are called greenhouse gasses because they prevent some of the heat from the earth escaping into space.

    the earth emits infra red radiation, this is the only way it can lose heat. this radiation can be absorbed by greenhouse gasses.  this causes them to become hotter( in the same way as a a microwave makes water hotter). this causes the earth to be warmer then it usaly would be.

  3. water - specifically clouds, is a greenhouse gas.

    if you&#039;ve paid attention to weather, you know that it cools off more on clear nights than on cloudy nights.  So clouds keep us warm.

    CO2 does the same sort of thing - keeps the planet from losing energy.

    you&#039;ll hear some claim that CO2 is only responsible for ??% of the greenhouse effect.  maybe they&#039;re right.

    BUT, consider, that during the last ice age, the average global temperature was only 6 degrees C cooler than today.

    it only takes a little cooling to make drastic changes.

    it only takes a little warming to make drastic changes also.

    in fact, over the last few years, the sun is apparently cooling (that is, putting out a bit less) radiation.  if the sun was the primary cause of climate change, we&#039;d be cooling.

    there are not a lot more or less clouds.  that&#039;s not a cause of climate change.

    what is different is the amount of CO2 in the atmosphere.  CO2, while a small part of the atmosphere, has increased about 40%.  that&#039;s a very large change.

    climate models have been created by many universities, and gov&#039;t agencies.  they have been tested using data from the last 20-30-40 years, and make predictions (for example using data that is 20-40 years old), that have already been shown to be true.  they work, and are reasonably accurate.  clearly not perfect, but pretty good.  and they generally agree with each other.

    HOWEVER, TO YOUR QUESTION,  CO2 has for billions of years been created by animals breathing, and plants have used that CO2, and released oxygen.  this process has been keep in pretty even balance.  the CO2 is just part of the atmosphere, held in place by earth&#039;s gravity, just like all of the air you breathe.

    what&#039;s different today is that we&#039;ve burned coal and oil that has been stored underground for millions of years, and the CO2 that&#039;s the result is now part of our atmosphere.

    that CO2, along with clouds, and methane, and other gases cause earth to retain heat.  in part, that&#039;s a very good thing.  without any of those, temperatures would be way below freezing, all over.  so, we like it to be warm.  not too cold, nor too warm, but just right.

    good luck.

  4. Carbon dioxide does not significantly trap other gases inside the earth. Nor do gases within the earth cause warming. To cause warming gases must be between he earth and outer space, and must reflect more long wavelength light than it reflects short wave light.

    Earth does get rid of heat into the sky by radiating long wave radiation, but also directly reflected light. Only when light has been absorbed and then re-radiated can the greenhouse effect be significant.

    Heat in the atmosphere does cause release of gases that in turn act to trap heat, and it prevents cloud formation which would have reflected more heat away from earth.

  5. Climate Change is caused by many different variables, including but not limited to - the sun, the oceans, man-made emissions, and gases released by the earth&#039;s crust. There is currently a debate over how much impact various emissions have on climate change. Directly answering your question, it is suggested that 95% of the earth&#039;s greenhouse gases is water vapor, most produced by nature. Therefore, though less than 5% of the remaining gases could come from the earth&#039;s crust and man-made emissions, it is reasonable to assume that they may not be fully responsible for global warming, but rather are just an additional contributing factor out of many.

  6. It sure looks that way.  The progression in scientific understanding on global warming is summarized in detail on this site:

    Here is what the balance looks like in terms of scientific evidence:

    http://norvig.com/oreskes.html

    The consensus was quantified in a Science study by Prof. Naomi Oreskes (Dec. 2004) in which she surveyed 928 scientific journal articles that matched the search [global climate change] at the ISI Web of Science. Of these, according to Oreskes, 75% agreed with the consensus view (either implicitly or explicitly), 25% took no stand one way or the other, and none rejected the consensus.

    Counting only peer-reviewed papers published in reputable journals is important because they are cross-checked by scientist peers who are also staking their professional reputations on the validity of the paper, its evidence, and its conclusions

    Some people claim that the sun is responsible for current warming, but that does not appear to be the case:

    &quot;There are many interesting palaeoclimate studies that suggest that solar variability had an influence on pre-industrial climate. There are also some detection–attribution studies using global climate models that suggest there was a detectable influence of solar variability in the first half of the twentieth century and that the solar radiative forcing variations were amplified by some mechanism that is, as yet, unknown. However, these findings are not relevant to any debates about modern climate change. Our results show that the observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanisms is invoked and no matter how much the solar variation is amplified.&quot;

    &quot;blaming the sun for recent global warming is no science-backed position anymore – it is deliberate disinformation. &quot;

    Scientists would love to find evidence that we are off the hook, but there is no alternate theory that has any widespread support, because the evidence does not point in reassuring directions.
