Many people have seen pictures of a volcanic eruption called Tonga in the Pacific Ocean. The epicenter was reported below the Pacific Ocean floor, however; no tsunami alert was issued. With each volcanic eruption, large amounts of ash, dust, and vapor are released. Depending on their strength, these dust particles can reach very high altitudes….

It turns out that these bubbles have formed because methane gasses are rising into the empty spaces created by melting permafrost. Like a ticking time bomb, the pressure is building up inside these bubbles…
The average global temperature during the last ice age 20,000 years ago was 7 degrees Celsius. The lowest average was minus 11. Researchers from the U.S. have made this crucial discovery by combining data from small marine fossils with climate models to predict the weather, known as the Last Glacial Maximum (LGM). During that cold…
