It's common knowledge among climate scientists that ice ages occur regularly on Earth. Multi-millennial winters set in about once every 11,000 years or so, and the latest one failed to start. Scientists believe that global warming and climate change are responsible for the current state of affairs.
The last ic... |

The scientist who first pointed out that global warming is a real phenomenon is now saying that the 2-degree warming target that we should strive to avoid is insufficient to prevent climate change. It is widely believed that warming needs to be kept under 2 degrees Celsius in order for the Earth to be safe.

About 18,000 years ago, the world was at the peak of the last glaciation, or Ice Age. Over the next thousands of years, massive amounts of carbon dioxide appeared in Earth's atmosphere, and researchers have been arguing that the deep ocean was the source. However, a new study shows this to be false.
