1859 is the year you wanna look at
The first recorded evidence of space weather effects on technology was in 1847 (Barlow, 1849). In 1859 a major failure of telegraph systems in New England and Europe coincided with a large solar flare (Tsurutani et. al., 1859).
HydroQuebec Power Grid blackout in Quebec, Canada, in March of 1989 that the world truly realized the extent to which solar storms can impact the economy. The solar storm induced a nine-hour blackout which affected 6 million customers and ultimately cost this power company more than $10 million
March 13, 1989 - The Quebec Blackout Storm
Most newspapers that reported this event considered the spectacular aurora to be the most newsworthy aspect of the storm.

Geomagnetic disruptions caused by solar flares can affect people and animals. It can cause disorientation to people, and can affect animals ability to navigate, etc. If the animals couldn't find their way to where they usually were, people wouldn't find food where they normally did, causing famines.
Earth’s magnetic field acts as a shield against the bombardment of particles continuously streaming from the sun. Because the solar particles (ions and electrons) are electrically charged, they feel magnetic forces and most are deflected by our planet's magnetic field. However, our magnetic field is a leaky shield and the number of particles breaching this shield depends on the orientation of the sun’s magnetic field. It had been thought that when the sun’s magnetic field is aligned with that of the Earth, the door is shut and that few if any solar particles enter Earth’s magnetic shield. The door was thought to open up when the solar magnetic field direction points opposite to Earth’s field, leading to more solar particles inside the shield. Surprisingly, recent observations by the THEMIS spacecraft fleet demonstrate that the opposite is true. "Twenty times more solar particles cross the Earth’s leaky magnetic shield when the sun’s magnetic field is aligned with that of the Earth compared to when the two magnetic fields are oppositely directed," said Marit Oieroset of the University of California, Berkeley, lead author of one of two papers on this research, published May 2008 in Geophysical Research Letters.
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter.
The temperatures of space plasmas are very high, ranging from several thousand degrees Celsius in the plasmasphere to several million degrees in the ring current. While the temperatures of the "cooler" plasmas of the ionosphere and plasmasphere are typically given in degrees Kelvin, those of the "hotter" magnetospheric plasmas are more commonly expressed in terms of the average kinetic energies of their constituent particles measured in "electron volts." An electron volt (eV) is the energy that an electron acquires as it is accelerated through a potential difference of one volt and is equivalent to 11,600 degrees Kelvin. Magnetospheric plasmas are often characterized as being "cold" or "hot." Although these labels are quite subjective, they are widely used in the space physics literature. As a rule of thumb, plasmas with temperatures less than about 100 eV are "cold," while those with temperatures ranging from 100 eV to 30 keV can be considered "hot."

A pod of dolphins beached themselves... now when the hell do you see that????
now anyone who wants to debate this, I will blow my top at them.
The Earth can be divided into separate parts: an outer crust, a highly viscous mantle, a less viscous outer core, and a solid inner core made up of mostly iron and nickel.
Circulating magma in the molten outer core generates a weak magnetic field, which the researchers suspect may be leaking into the inner core and generating an electric current. The twisting force generated by this electromagnetic interaction may be what drives the inner core's rotation.
The Earth's major wobble is caused by the Moon and Sun tugging on the Earth's bulging equator, creating an effect that lasts 25,800 years called precession.
Many scientists firmly believe Earth's wobbles have caused the extinctions of life on Earth more than once. They have been responsible for massive earthquakes, major volcanic activities, and some say Earth's wobbles have caused the North and South Poles to change places.

Wonder if that was what effected the bees awhile back when they were not returning to the hive? And what ever happened with that anyway? Funny how you never hear the follow up. I see bees in my garden now...
