Greenhouse Gases, Feedbacks, and Scenarios

It is a widely accepted scientific that the emissions are causing a runaway case of the Greenhouse Effect. This is seen in a few ways. First, the land based ice is melting and causing the sea level to measurable rise. Also, the freshwater from the ice that is melting into the ocean is causing a salinity change in the water. This in turn is causing climate shifts like variable rain patterns and more violent storms. The ocean's pH is also decreasing (more acidic) due to the increasing the amount of carbon dioxide in the atmosphere that is dissolving in the ocean.

Some factors that are variable and difficult to predict the impact on the GCC are aerosols. First, only 10% of the aerosols are man-made. This means that 90% of the particulates in the atmosphere cannot be controlled by human prevention. Sea level rise is variable as well. It is known that the models that the IPCC has set up do not take into account all the data. The known empirical models are also flawed. Another debate is sea level rise versus thermal expansion of the sea. It is difficult to predict the impact of these two variables.

Personally, it is possible that scenario A1 could happen within the next 100 years. We see a rapid growth in technology. Technology can be seen in crop production methods, bioengineering plants to grow more efficiently, harvesting techniques. This has pushed the rise in population and can continue to push to rise in human population. Through digital and electronic technology we see that the world has shrunk and business is done 24/7 from anywhere at anytime.
