Smart folk back in 1898.
In 1898, Svante Arrhenius became the first scientist to connect global warming and fossil fuel combustion when he proposed a relationship between atmospheric carbon dioxide and temperate. According to the technology website Lenntech, Arrhenius calculated that a doubling of carbon dioxide concentration would subsequently lead of a 5 degree temperature rise on Earth. And more strikingly, Arrhenius was far ahead of his time when he and Thomas Chamberlin announced human activities were likely responsible for the addition of carbon dioxide to the atmosphere.

Still, scientific papers clearly demonstrate that global surface temperatures have risen primarily due to human-induced emissions of greenhouse gases. And in research published this week, scientists have found that 2014 was the hottest on Earth since record keeping was first instituted in 1880. According to the New York Times, extreme heat blanketed many parts of the world, including the ocean surfaces (except in Antarctica), which provided the energy needed for last year’s Pacific storms. As Michael H. Frielich, director of Earth sciences at NASA told the Times, “Climate change is perhaps the major challenge of our generation.” It can also have dire consequences for human health.
In contrast to the unusual heat in most areas of the world, parts of the U.S. East recorded below-average temperatures in 2014. However, some scientists believe that such temperatures are an example of extreme weather patterns that are an indirect consequence of global warming.
