electric discharge craters NOT meteor impact craters
The Last Ice age came to an abrupt end at or around about 9,700 B.C. according to ice-core data-sheets relating to temperature and CO2 and other gases... now, Free Planet has explained before that all the evidence points towards a Solar Model that gradually tends to Ice Age (today's global temperature minus nine degrees) over a period of 120,000 years until 'some intensely-heating event' bumps it back up to today's temperature values. So, what heated up the planet when it tends to Ice Age?
Radiative cooling by Outgoing Longwave Radiation is the primary way the Earth System loses energy. The balance between this loss and the energy gained by radiative heating from incoming solar shortwave radiation determines global heating or cooling of the Earth system (Energy budget of Earth’s climate). Local differences between radiative heating and cooling provide the energy that drives atmospheric dynamics. [source OLR]
Free Planet is an advocate of EUT or the Electric Universe Theory and the protection offered by the Solar Wind of our local star, i.e. sunspot and coronal hole activity of our Sun, might save us from much worse things that the galactic center could throw at us. For example, the Carrington Event of 1859 happened during a solar minimum, so might not (necessarily) have been our-Sun based. We might have just been low on solar-wind protection when some other 'cloud of galactic energy' swept through our Solar System.
Kinda interesting i.e. utterly terrifying new science.
