Humans have triggered an era of ‘de-glaciation’
The build-up of heat-trapping greenhouse gases in the atmosphere could delay onset of Earth’s next ice age by 100,000 years, scientists estimate in a new study published this week in Nature.
The researchers reached their findings after “cracking the code of glacial inception,” according to a statement from the Potsdam Institute for Climate Impact Research, who said the relationship between incoming solar radiation and CO2 levels are the key factors that explain the last eight glacial cycles in Earth history.

Abysmal waters play huge role in global carbon cycles
By Summit Voice
FRISCO — The remote Southern Ocean, encircling Antarctica, may be a key driver of the carbon cycle, inhaling and exhaling enough carbon to help shift the global climate in and out of ice ages.
For decades, scientists have been trying to figure out what exactly, along with the known wobbles in Earth’s journey around the sun, may cause the huge shifts that lead to vast ice sheets covering many of the planet’s land masses.
