  • human activities that contribute to global warming
  • burning of fossil fuels (coal, oil, and natural gas)
  • clearing of land.
  • reates carbon dioxide, whose chemical formula is CO2. CO2 is a greenhouse gas that slows the escape of heat into space. Trees and other plants remove CO2 from the air during photosynthesis, the process they use to produce food.

  • It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases.
  • More than 80% of the world-wide energy demand is currently supplied by the fossil fuels coal, oil or gas.
  • energy demand is simply too high.

  • Why have warnings about climate change been ignored for more than 20 years?
  • The true cause of global warming is our thoughtless attitude to Nature.
  • Why were ever more scientific evidence demanded to find the coherence of man-made CO2 emissions as cause of global warming? Why wasn't common sense reason enough to act?
  • Why can one still today find people who stick their head in the sand and don't want to understand what's going on in the earth's atmosphere?
  • Why do most people refuse to change their personal behavior voluntary in order to reduce CO2 emissions caused by their activities?
  • The answer to all these questions is a rather simple one:
  • In our technology and scientific minded world, we seem to have forgotten that mankind is only a relatively minor part of Nature. We ignore being part of a larger whole.
  • It's your personal decision whether you want to be the cause of global warming
  • In this context the question is whether global warming and its effects will eventually wake up mankind and spark off a change of paradigm. Will we understand this hint of Nature to follow the true meaning of life or will we continue to let us manipulate by media and advertisement as sheer and willing consumers in the economic cycle? Will we continue to strive for power, prestige and possessions following the concept „the more the better "? Shall economic growth and an ever increasing personal income continue to be the reason for being here, beyond everything else?

    This website looks very reliable, and it mentions that humans need to realize that it's time for for a change, because global warming is becoming more visible, and scientists have said that global warmings' main cause are humans... With my argument.

  • All fossil fuels release carbon whenever they are burned, but coal has a much higher carbon content than either oil or gas.
  • The other two fossil fuels, oil and natural gas, are also used to produce electricity, but not as often as coal. Oil and gas are primarily used to heat homes and factories, as well as fuel all forms of transportation from buses to ships and motorcycles to airplanes.
  • Carbon dioxide is a colorless, odorless gas that is naturally present in the atmosphere, but only in tiny amounts.
  • oxygen and nitrogen comprise about 99 percent of atmospheric gases
  • carbon dioxide is only a trace gas, it is essential for life.

  • "ice caps" near Mars's south pole had been diminishing for three summers in a row.
  • Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.

  • ice ages throughout their histories.
  • "Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said.
  • Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars.

  • The Earth heats up after a Solar Grand Maximum, lagging a bit after the peak. With a Solar Grand Minimum now on its way, a "global cooling" is on the horizon--a natural oscillation occurring in much longer solar cycles.
