Global Warming May Have Halted an Emerging Ice Age, Study Suggests

According to researchers, North America's largest ice sheet began to grow 2000 years ago, which is a gradual beginning of a new cold phase, but people shook the system.
The Arctic glaciers had returned to gain ground and the Earth had entered a new cold phase, but the greenhouse gases turned back to the geological cycle.
Greenhouse gases interrupt the natural cooling of the planet and lead to the withdrawal of historical ice masses.
Global warming may have halted an emerging ice age, study suggests
Two thousand years ago, the Arctic remnants of a once-vast ice sheet started to grow again. It was the beginning of a new glacial period, more conversationally known as the next ice age—but by the 1960s, summer temperatures were already so high that the ice sheet started to shrink. In other words, global warming ended a period of glaciation that had already begun.
The next ice age may have started 2,000 years ago. But man-made global warming stopped it just a few decades ago. With the regularity of a metronome, over the past two million years the Earth has alternated long glacial periods with warmer ones. The mechanism that marks the rhythm is well known: the slow variations of the Earth’s orbit and the inclination of its axis modify the amount of solar energy that reaches the polar regions. So when the n…
Climate Change Stopped the Next Ice Age
New research shows that 2,000 years ago, remnants of an Arctic ice sheet began growing again, marking the start of a new glacial period—what we commonly call an ice age. But by the 1960s, global warming had raised summer temperatures enough to reverse that growth.
