Global warming is on the lips of many people. Fingers are being pointed in every direction trying to find someone, people, to pin it on. The only issue with these accusations is that most people fail to take into account the blatant information that shows it is a natural occurrence.
Carbon Dioxide, a natural byproduct of respiration and burning fossil fuels, makes up less that 5% of green house gasses in the atmosphere but receives most of the blame. The leading green house gas in the atmosphere is water vapor of which the majority is put there by volcanoes. Accurate record temperatures were not kept until 1880. In 1883 the eruption of Krakatoa caused a mini ice age dropping the average global temperatures 2.2 degrees Fahrenheit which did not return to normal until 1888. The start of record keeping began at a cooler time in our history.
There is also the changes in ocean currents, carrying warmer water to areas that would see these cooler temperatures and thus warming those areas. These currents can be affected by solar activity. Variations in this activity also creates a warming trend. Sunspots, a direct measurement of solar activity, documented for the past 400 years are showing that when we are experiencing more of these sunspots, it is warmer and when there are fewer sunspots the planet cools. During the Maunder Minimum, 1645 to about 1715, almost no solar activity was recorded. In that period temperatures were 2.7 degrees Fahrenheit colder globally. Since then we have seen a gradual increase in solar activity and global temperatures. Currently we are in the Modern Maximum and it is the most active period of solar activity on record.This isn’t the warmest period scientists have found evidence of. How do we know that? Carbon-14 measurements shows that a period about 1,000 years ago during the medieval ages was as warm, if not warmer, than it is now. This period of warmth predates fossil fuel use by around 800 years (before we had trucks and cars). We simply do not have enough accurate data to gauge the climate of our planet to decide if this is simply a natural act by the environment itself.Based on the evidence given through our planets history of cooling and warming trends, there is little indication to prove that humans are responsible for it. Scientists are still debating, but the left is quick to put the blame on fossil fueled capitalism.
