Nasa has said that the effects of the current El Nino weather phenomenon could be as bad as those of 1998, the strongest on record. El Nino is a naturally occurring weather system which happens every two to seven years, bringing severe droughts and devastating flooding in different parts of the world.
Looking back to 1998, there was a Saturn square Neptune as there is now. Other particularly severe E Ninos:- in 1972 there a Saturn opposition Neptune. In 1925 and 1891 there was also a Saturn square Neptune.
In two other years recorded as strong El Ninos, 1982 and 1875/6 there was a Saturn sextile Neptune which is weaker – so a less obvious connection. Though 1875 which oversaw droughts and great famine in India and China for three years after also had Saturn square Pluto at the start and Uranus square Pluto as well.
So the Saturn square Neptune uncertainty which is hanging around now, and continues until after mid 2016, may well in part be connected to the extreme weather patterns.
