Why global warming has not been altered by human activities

Evidence that global warming has NOT been altered by human activities

1. Anglia global warming
Emails hacked from scientists of the Hadley Climatic Research Unit at Britains University of East Anglia suggest questionable methods of how data analyzing human induced global warming have been recorded and interpreted. Emails show that researchers have debated deleting information requested by critics. They also discussed removing posts from publications where critics' papers were published. What does this mean and why should you care? Science should be evidence based and when data is analyzed by another party they should get the same results as the previous party. The scientists  considerations regarding deleting information raises concerns of the accuracy of the data that was collected. Did they ignore data that did not support their claims and are afraid that they will be found out? Why the secrecy and thoughts of removing posts if their claims are accurate, honest, complete and science based? On the other hand were these emails forged or altered? The best way to settle the dispute of the accuracy of these results would be to redo the calculations by several groups of unrelated scientific parties and see if they get the same results. Until then the results produced by these scientists may be biased.

What hacked emails from scientists really say

2. Solar flare activity
   The graph below shows that there is no relation between an increase in carbon dioxide and increase temperatures. However, the increase has a relation with solar activity. As solar activity increases temperature increases as emitted radiation from the sun increases. Therefore increased temperatures is not a result of an increase in carbon due to human activities but to excess radiation from increased solar flares.

3. Medieval Global Temperature Optimum
Between the 10th and 14th centuries summer temperatures were between 1 and 1.4 degrees higher than they are now in the 20th century. This change was caused by a change in air circulation over the Atlantic. In the 10th and 14th century their were less automobiles than they are now and less air pollution caused by the release of carbon from exhaust. If temperatures were hotter then before humans really began burning fossil fuels then hotter temperatures may just be a normal occurrence.

4. Little Ice Age
The Little Ice Age occurred between 1300 and 1400. The temperature was 1.5 degrees Celsius lower than previous years and great seasonal variation was exhibited. Again this time period occurred before humans began burning fossil fuels and "drastically began altering the Earth". These changes are becoming apparent again as we have experienced colder and longer winters along with hotter summers and seasonal variations. Again the effects of global warming can just be natural occurrences that happens approximately every couple hundred years then reverts back.
