Man made global warming is a myth.

Global warming has been caused by natural cycles and is probably causing the warming we see now by a small extent. However, humans cause the major changes in climate change that we are witnessing. So, since natural cycles caused the prior climatic changes, I do not need to debate your first statements. However, your last point says that scientists have been observing cooling trends. To prove my point, 2010 and 2005 are the hottest years on record since recordings began in 1880. Also, 1998 was the third hottest year on record, HELPED by a strong El Niï¿½o that made global warming larger in addition with man made contributions. Also on the link it shows the recorded temperatures, and you can see that global temperatures have been rising significantly since the late 1970s. Before this, natural phenomena probably had a larger affect since humans weren't as industrialized then, and the recent growth of the third world made CO2 emissions greater. So, since in the past 30 years the world became more industrialized more than ever before, CO2 emissions rose, and therefore climate change grew. http://arstechnica.com... Your other points say that Global Cooling is occurring, NOT global warming. True, there WAS global cooling for a brief period in the 1970s, but this was only temporary. In fact, scientists believe that the 20th century was overall a period of global warming; http://en.wikipedia.org... Also, strange events are occurring because of global warming. The world becomes warmer overall, but certain areas will experience more extreme, or even colder weather, which is caused by La Nina and El Nino. La Nina and El Nino are also becoming more extreme due to the warmer oceans. The oceans are becoming warmer because of the melting ice caps, and the ice caps are melting because of the man made global warming! So, as Earth gets a warmer mean temperature, other areas will experience traumatic weather and sometimes colder weather because of La Nina, El Nino, and the oceans warm/ cool currents. You also said that the polar bear population is at an all time high. Out of the 19 polar bear species, 8 are declining, 3 are stable, 1 is increasing, and 7 don't have known data. http://en.wikipedia.org... You say that the oceans temperatures are decreasing, which is probably not the case. As you can see on the following graph, the temperatures of oceans have increased because of the melting glacier caps. http://upload.wikimedia.org... You also say sunspots are solar phenomena is causing the most of global warming [probably]. As you can see from the following graph, solar output has decreased EVEN THOUGH TEMPERATURES INCREASED. So, you can tell that solar output is having a minimal role in our current global warming. http://en.wikipedia.org... Lastly, the huge majority of scientists believe that global warming is caused by man made contributions. In fact, 97% of them do! http://content.usatoday.com... In addition, CO2 is necessary to sustain human life, by making life on Earth warm enough. However, when CO2 was released on a large scale because of human activities in the past 75 years or so, it caused our Earth to warm. It is found in the atmosphere, and when sunlight reflects off the Earth, it is prevented from escaping our atmosphere because of CO2. With all of the new CO2 released as pollutants of products, it is trapping too much sunlight, warming our planet. This is what the Greenhouse Effect is, our Earth warms because of all of that trapped infrared radiation! True, water vapor is more plentiful than CO2, but CO2 takes hundreds of years to get out of the atmosphere varying with some staying for THOUSANDS of years, while water vapor is removed every few days or so in most cases as rainfall. You can also see that CO2 concentrations have continuously risen for the past 50 years and more. Other emissions such as Methane affect Global Warming to a lesser affect. http://en.wikipedia.org... http://www.google.com... (the fluctuations are caused by the difference in summer and winter, because in summer, plants absorb much CO2, but not too much of it). Also, some politicians advocate a smaller carbon footprint for individuals, but they do not seek to control the populace with laws. However, they seek ways to make people reduce their footprint with less meat, better transportation, etc. And to reduce the emissions of businesses, politicians probably support a Cap and Trade system to reduce emissions.
