An Instance of Global Warming

Is global warming pseudoscience? Not according to Angel Oliveros Zafra, a Spanish farmer. He said that he is starting to notice differences in the behavior of the different seasons. For example, a stream nearby Angel’s farm usually dries up during the summer, but is already dry and summer has yet to come. The changes in weather are affecting the yields of his crops. According to the article, Angel’s annual yield of vegetables and olives has dropped by a tenth in recent years. Mr. Zafra says that man-made global warming is the primary adversary for these odd occurrences. Unseasonable frosts and winds are destroying his crops.

Is global warming a real threat? Recently it seems that there are unnatural occurrences like melting ice caps, higher temperatures, and a decline in annual crop yields. If global warming is indeed scientific fact, then the world is not, and has not been polluting at a socially beneficial level. Theoretically, the world will not last forever. Do the current economic models completely prevent the degradation of the environment? Or do they only suggest the appropriate amount of emissions or residuals in relation to human willingness to pay or accept these emissions?
