Due to the bone-chilling temps caused by the recent Polar Vortex, many North Americans (myself included) were contemplating moving closer to the equator. Those who are skeptical about climate change were quick to use the extreme cold as a way to disprove global warming. Don't let the Arctic Vortex temperatures fool you, or those who are trying to dismiss climate change. Global temperatures are on the rise, resulting in extreme weather. Researches have found irrefutable evidence showing the Arctic is the warmest it has been in 44,000 years.
