Galactic plain Vs. Galactic center, 3 million years ago our Sun crossed the galactic center or the black hole in the middle of the milky Way galaxy. On 12-21-2012 the Sun came into alignment with the galactic plane, otherwise known as the dark rift, there is a massive dark energy/matter vacuum in this alignment between our Sun and the Milky Way center plain, so while we are in this Gallactic plane this will drain the energy of the Sun and thus lower the energy output of our Sun, that being said, most of the northern hemisphere will see cooler weather but because the Earth travels between the Sun  and the Galactic plane through this dark energy/matter vacuum field in December or the southern hemispheres summer months, Australia and other parts of the Southern hemisphere will experience higher than normal temperatures. I'm sure This will cause some crazy scientific debates as to what is causing this event but rest assure it's the DARK RIFT and Human activity on Planet Earth causing climate change............
