Researchers say they know when the next ice age will come. Wikipedia says: "An ice age is a long period reduction in the temperature Earth's surface and atmosphere, resulting the presence or expansion continental and polar ice sheets, and alpine glaciers." The researchers are Cardiff University the UK. They predicted that the next ice age should arrive 10,000 years from now. However, the scientists believe it could be delayed because human activity. A member the research team said climate change could delay the next ice age. She said global warming could make it "very unlikely" that the next freeze will arrive time.
The scientists said melting glaciers the North and South Poles will push back the next ice age. Lead researcher Professor Stephen Barker studied what caused past ice ages to happen. His team looked nearly one million years climate data. They found that there was a relationship between changes the Earth's axis, global temperatures, and the size Antarctica and the Arctic. When the amount ice the continental ice sheets was stable, ice ages happened regular intervals. However, Professor Barker said less ice means a longer gap ice ages. He added: "Earth's climate is an interconnected system complex processes, all acting together to produce the changes we observe."
