Whenever global warming makes headlines in the news, there are those who come out to show evidence against global warming. Considering both sides of the argument can help you reach a conclusion of your own.
Global warming is defined as the hypothesis that the Earth is warming due to the accumulation of greenhouse gases. Theories and some evidence point toward these gases being produced by the burning of gas, oil, coal and wood.
Evidence Against Global Warming
One of the claims against the global warming theory is the absence of evidence in its favor. Rather, instead of refuting global warming by pointing to contradictory evidence, some of the evidence against global warming is what some people see as a lack of evidence for it. Other facts do have correlating evidence on the other side of the claim, leading believers and non-believers in global warming to square off on some issues.
Lack of Evidence
Those who belive that there is no evidence for global warning often argue that extremely accurate temperature gauges that can measure temperatures to within .01-degrees Celsius have shown no evidence of global warming over the last 25 years. While some can consider this a plateau, these satellite readings correspond with land readings taken for years before this; there has been little recorded climbs in temperature.
While many scientists are willing to go on record to point out trends in global warming, more than 17,000 scientists have signed a petition circulated by the Oregon Institute of Science and Medicine saying that they see no evidence of global warming at all. Less formal surveys amongst climatologists have pointed in the same direction.
No Future Prediction
While it is tempting to look ahead at what global warming could do if left unchecked or untreated, it is currently impossible to predict actual climate change in this manner. There are currently no computers sophisticated enough to extrapolate from current data in a reliable pattern that can indicate future climate temperatures.
In fact, if past predictions of the future were true, the current climate and state of the globe would be much, much worse than it actually is. Scientific predictions and evidence have been proven false already, leading skeptics and other scientists to wonder about the usefulness of predicting global warming trends for the future.
Climate Change of the Past
The fastest climate change recorded and speculated has always come at times when emissions from man were either non-existent or at much lower levels than they are today. More importantly, there is evidence that carbon dioxide levels increased after an increase in temperature and not before. From this evidence can be taken that climate change or global warming are a natural occurrence and not a man-made one.
The Misleading Term of Global Warming
The media has fastened onto the term of "global warming", which in turn has caused skeptics and non-believers to point out the lack of evidence for this trend. What some scientists believe is occurring, is actually global climate change.
Climate change can be seen as an effect from urban dwelling hot zones, to cooling in some cases caused by carbon dioxide emissions. In other words, the issue may not be as cut and dry as the Earth simply growing warmer. Global warming may be the end result, but the term allows for evidence to be brought to light against what may be a very real phenomenon.
Those trained in social sciences have the ability to find data to back up their arguments. The same can be said for skeptics and believers alike in the case of global warming. There may be evidence for global warming, but it is frequently offset by evidence against global warming taken from similar data. The truth may come from attempting to understand climate change as a whole, including temporary cooling and heating cycles. Global warming may be a fact, but until evidence can be produced that refutes the evidence against it once and for all, the debate will continue to rage on.
