Wow, what a winter this is shaping up to be, huh? It seems like every other week we're getting hit with another "extreme cold" weather even on the northern half of this planet.
These events are not only catching people off guard but animals too. From fish in Norway to dogs in Colorado, there are a lot of animals that are being frozen in place by cold weather.
But do you think these means there is no such thing as global warming? Or do you think this is just a blip on our way to a hotter planet? Leave me you opinion in the comment section below...
SOME INFO ABOUT POLAR VORTEXES FYI
A polar vortex (also known as a polar cyclone, polar low, or a circumpolar whirl) is a persistent, large-scale cyclone located near either of a planet's geographical poles. On Earth, the polar vortices are located in the middle and upper troposphere and the stratosphere. They surround the polar highs and lie in the wake of the polar front. These cold-core low-pressure areas strengthen in the winter and weaken in the summer due to their reliance upon the temperature differential between the equator and the poles. They usually span less than 1,000 kilometers (620 miles) in which the air circulates in a counter-clockwise fashion (in the Northern Hemisphere). As with other cyclones, their rotation is caused by the Coriolis effect.
The Arctic vortex in the Northern Hemisphere has two centers, one near Baffin Island and the other over northeast Siberia. The Antarctic vortex in the Southern Hemisphere tends to be located near the edge of the Ross ice shelf near 160 west longitude. When the polar vortex is strong, the Westerlies increase in strength. When the polar cyclone is weak, the general flow pattern across mid-latitudes buckles and significant cold outbreaks occur. Ozone depletion occurs within the polar vortex, particularly over the Southern Hemisphere, and reaches a maximum in the spring.
SOME INFO ABOUT GLOBAL WARMING FYI
Global warming refers to an unequivocal and continuing rise in the average temperature of Earth's climate system. Since 1971, 90% of the warming has occurred in the oceans. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980. Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850.
