This interesting video discusses global warming as a possible result of rising earth core temperatures due to interaction with an approaching binary companion star to our sun. As a result of earth being affected by the immense magnetic field and gravitation of this brown dwarf, more deep sea volcanoes are erupting, thereby heating the oceans, melting polar ice and emitting increased carbon dioxide.

The explanation may have merit, since climate and weather are determined mainly by ocean temperatures, and not the other way around. It might also help explain at least one impetus (among other suspected insidious purposes) behind geoengineering as an attempt to dim sunlight, in a brute force attempt to counteract the greenhouse effects of increasing CO2 in the atmosphere. Chemtrails also make it more difficult to discern what is happening in space, thereby lessening the odds that people will notice celestial abnormalities.
