There is no anthropomorphic global warming

"There is no anthropomorphic global warming Global warming has occurred in the past hundred years. This warming occurred mostly in the first half of the 20th century, counter to the period when there was more co2. Correlation between sunspot activity and temperatures are higher than co2 and temperature." As Pro there is still a burden of proof on your behalf outside of simple refutation. "Global warming is caused by human activity." "No it isn't." Doesn't really cut it. No: 4 : to imply a meaning expressed by the opposite positive statement http://www.merriam-webster.com... Anthropomorphic: 1 : described or thought of as having a human form or human attributes. 2 : ascribing human characteristics to nonhuman things. http://www.merriam-webster.com... I am assuming the error is on your part in saying that global warming is 'not human like' as opposed to 'not being human caused'. If I am mistaken round two will be interesting. :) ================================================================================ "This warming occurred mostly in the first half of the 20th century" "The three warmest years on record have all occurred since 1998; 19 of the warmest 20 since 1980. Overall land and sea surface temperatures for the world were second highest in 129 years of record keeping, trailing only 2002..." (NOAA's National Climatic Data Center: 2008). Our influence on Earth's climate did not begin a few decades or centuries ago, but 8000 years before; with the birth of agriculture (see anthropocene). In a study at the University of Virginia, ancient human activities have shown to have affected the climate. Key discrepancies in levels of greenhouse gases revealed by ice cores show that during the previous three periods between ice ages, levels of carbon dioxide and methane in the air fell in lock-step with decreases in summer sunshine caused by cyclical changes in Earth's orbit. However after the most recent ice age, which peaked around 12,000 years ago, both gases broke the set pattern. Levels of atmospheric carbon dioxide began to increase 8000 years ago, followed by methane 5000 years ago, even though summer sunshine has been decreasing. "Both gases followed the expected trend for a while but then went up instead of down." After removing possible natural causes for the greenhouse gas increases, it is probable that early farmers who cleared forests in Europe, India and China accounted for the surge of carbon dioxide, while rice paddies and burgeoning herds of livestock produced the extra methane. Over time this activity laced the atmosphere with about 40 parts per million of carbon dioxide and 250 parts per billion of methane, enough to produce nearly 0.8 ï¿½C of warming before 1700, around the dawn of industrialisation. Which just about equals the warming humans are thought to have caused since then. http://www.newscientist.com... http://courses.eas.ualberta.ca... "Correlation between sunspot activity and temperatures are higher than co2 and temperature." For as long as I have been alive, global trend of temperatures has risen. This is a strong correlation. :P The sun emitted a third less energy about 4 billion years ago and has been brightening since. For most of this time, Earth has been warmer than today, (faint sun paradox). The reason: higher levels of greenhouse gases which trap more of the sun's heat. Solar fluctuations and other factors such as dust ejected by volcanoes - and average global temperatures may well have been largely responsible for warming in the late 19th and early 20th century, leveling off during the mid-century cooling. However there is no positive correlation at all between solar activity and the strong warming during the past 40 years. http://stephenschneider.stanford.edu... The evidence that CO2 is a greenhouse gas depends mainly on physics, not on the correlation with past temperature, which tells us nothing about cause and effect. And while the rises in CO2 a few hundred years after the start of inter-glacials can only be explained by rising temperatures (i.e. temperature and CO2 levels are reciprocal), the full measure of temperature increases can only be explained by inclusion of the human influenced rise in CO2 levels.
