Researchers say the planet seem naturally on track to escape an ice age for the next 50,000 years, an unusually long period of warmth. Global warming could stave off next ice age for 100,000 years ...
Throughout Earth's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than one million years ...
Shows the pattern of temperature and ice volume changes associated with recent glacials and interglacials. An interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.

This area was covered by an ice field during the last ice age, and preliminary data from Hall’s research suggest the ice had collapsed back to its center by around 18,000 years ago.
By measuring the size of the grains and calculating their age, scientists can estimate how much Amoc has slowed over time. Another piece of evidence is the so-called 'cold blob' or 'warming hole ...
According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. [246] With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. [247]
The Arctic is warming four times faster than the rest of the world, which means the difference between temperatures up north and down south are shrinking, Francis said. Arctic sea ice is shrinking, especially near the Barents Sea in Scandinavia, which releases more heat into atmosphere. That means more energy bouncing off and warping or moving ...
