Our Planet’s Axis IS Shifting: Scientists Just Figured Out What’s Causing Earth to Wobble
Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth. Droughts are causing Earth to wobble on its axis, according to new research. Scientists have long known … Continue reading
Ice Ages And Earth’s Wobble
For more than a century scientists have known that Earth’s ice ages are caused by the wobbling of the planet’s orbit, which changes its orientation to the Sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions. The Northern Hemisphere’s last ice age ended about 20,000 years ago, and most evidence has indicated that the ice … Continue reading
