Trickle-down is the solution (To the planetary core formation problem). Scientists have long pondered how rocky bodies in the solar system -- including our own Earth -- got their metal cores. According to new research, evidence points to the downwards percolation of molten metal toward the center of the planet through tiny channels between grains of rock. Source 7v.

Planet Spinning - Earth the History

Did the Chicxulub asteroid knock Earth's thermometer out of the ballpark? When the Chicxulub asteroid smashed into Earth 65 million years ago, the event drove an abrupt and long-lasting era of global warming, with a rapid temperature increase of 5° Celsius © that endured for roughly 100,000 years, a new study reports.

Carbon 'leak' may have warmed the planet for 11,000 years, encouraging human civilization. The oceans lock away atmospheric carbon dioxide, but a 'leak' in the Southern Ocean brings the greenhouse gas back into the atmosphere. An international research team looked at minute nitrogen concentrations embedded in diatoms, forams and corals to identify an increase in Southern Ocean upwelling during the past 11,000 years, which could explain the otherwise mysterious warmth of the Holocene that allowed human populations to flourish.
