Climate change can't possibly be happening, part three

Who could possibly believe that climate change is a result of human activity on earth? Many people are in denial or don’t want to address the issue, including all 20 republicans running for the senate.

With all the seemingly convincing arguments about climate change on both sides, it can become a confusing issue. Have you ever tried to read a scientific paper on climate change? It can be daunting for most of us.

So, in the last two blog post, the practical side of climate change and its causes have been explored. In the first blog post, “Climate change can’t possibly be happening”, the issue of using fossil fuels was explored. In conclusion, humans are using a thousand years’ worth of stored carbon each year for our energy use. That is much more carbon being released than the environment can absorb, even when you include the oceans.

In the next blog post, “Climate change can’t possibly be happening, part two”, the issue of rising carbon levels and what affect carbon has on the world’s weather. Carbon levels in the atmosphere have been rising for the last 60 years. The levels are the highest they have been in 17,000 years. With all that carbon in the atmosphere as carbon dioxide, the clear molecule is allowing light from the sun to strike the earth but is keeping the heat generated by the sun light in.

In a practical approach to climate change it is fair to ask if the average temperature of earth’s atmosphere is rising with all the release of carbon? The answer is a resounding, yes!

According the NASA, the average temperature has been on an upward trend since the 1880’s.  When you look at a global picture of rising temperatures, you find that the only place that hasn’t experience a rise in temperature is a small part of the south arctic region.

This rise in temperature can also have a accelerating effect. With the average temperature of earth’s atmosphere on the rise, more snow melt will happen. Not only on the North and South Pole, but also glaciers around the world and less snow accumulation during the winter. Snow and ice reflect light back into space. This keeps the light from being absorbed by the earth. When there is less snow, more sunlight will heat the earth.

So how does this relate to the policies of a Responsible Community? In the next and final post of climate change, the response of the community will be explored.
