According to NASA, “97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are very likely the result of human activities.”
Furthermore, the earth has unequivocally warmed dramatically since the 1950s, due in most part to human activities. In fact, during that time period, many of the observed changes are “unprecedented over decade to millennia.”
The earth is like a greenhouse. The technology we use, as well as normal human activity, have resulted in ever increasing amounts of gases being released into the atmosphere. The build-up of these greenhouse gases prevents heat from escaping the earth’s atmosphere.
This, in large part, leads to the current symptoms of climate change we have all experienced: warmer climate and ocean temperatures, more extreme weather events, a rising sea level, and dilution of the ocean’s salinity from melting glacial ice sheets to name a few. [Read more…]
