The Climate was Cooling? Wait what?

Yes, it is true. In the mid 20th century the globe was actually cooling due to aerosol emissions. The globe only cooled about 0.1 degrees Celsius, but this was a huge change in the trend of the 20th century. The aerosols had such an influence on the climate because it has direct and indirect effect. The aerosols were put in the atmosphere primarily from burning fossil fuels. The primary idea from reading this article and this article is that the cooling during this time was unexpected and was very confusing at first. When the scientists were able to study it more once they realized it was a hiatus, it became more evident that the sulfate aerosol emissions that us humans were producing. The skeptical science website and the article by Jeff Tollefson both seem relatively reliable. I personally felt like the article used more facts and science to make complete sense out of the subject. Tollefson is a reporter for Nature magazine, which is a well known and highly reliable source.
