(Mashable) – UPDATED 2:45 p.m. ET: Since this story was posted, yet another storm — Hurricane Patricia — in the eastern Pacific intensified to Category 4 status [and then, Category 5 –Des], making it 22 Category 4 and 5 storms that have formed so far this year.

The combination of El Niño, other natural climate cycles and global warming have supercharged this year's tropical cyclone season in the northern hemisphere to the point where all-time records have been blown away.

Specifically, there have now been 21 typhoons and hurricanes in the hemisphere — all but one of which occurred in the Pacific Ocean — that have reached the most intense levels of the Saffir Simpson Hurricane Wind Scale, Category 4 and 5. This beat the past record of 18, set in 2004.

One of the strongest El Niño events ever recorded has provided storms with an ample amount of fuel in the form of warm ocean waters across the tropical Pacific, and has also helped squelch tropical activity in the North Atlantic Basin.

On average, El Niño years have higher readings on a scale known as the "Accumulated Cyclone Energy", or ACE, index. This index measures both a storm's intensity and its lifespan. To date, the ACE index across parts of the Pacific is off the charts, says Philip Klotzbach, a research scientist at Colorado State University.

Evidence of El Niño's influence is strong, considering that only one of the Category 4 or 5 storms in the hemisphere this year occurred in the North Atlantic Ocean. [more]

    Humans are born with an overdeveloped skill (understanding, self-knowledge) which does not fit into nature's design. The human craving for justification on matters such as life and death cannot be satisfied, hence humanity has a need that nature cannot satisfy. The tragedy, following this theory, is that humans spend all their time trying not to be human. The human being, therefore, is a paradox.

    There are four principal defense mechanisms that humankind uses to avoid facing this paradox:

    Isolation is "a fully arbitrary dismissal from consciousness of all disturbing and destructive thought and feeling"

    Anchoring is the "fixation of points within, or construction of walls around, the liquid fray of consciousness". The anchoring mechanism provides individuals a value or an ideal that allows them to focus their attentions in a consistent manner. "God, the Church, the State, morality, fate, the laws of life, the people, the future" are all examples of collective primary anchoring firmaments. (The earth/Gaia)

    Distraction is when "one limits attention to the critical bounds by constantly enthralling it with impressions". Distraction focuses all of one's energy on a task or idea to prevent the mind from turning in on itself. (Sound familiar environmentalists?)

    Sublimation is the refocusing of energy away from negative outlets, toward positive ones. The individuals distance themselves and look at their existence from an aesthetic point of view (e.g., writers, poets, painters).
