How Humanity’s Water Usage Is Nudging Earth’s Tilt
MAI-MNE SUB-ZONE, SOUTHERN REGION, ERITREA, JUL 10 – Nearly 7,000 dams built since 1835 caused a 1.1-meter pole shift and lowered global sea levels by 21 millimeters, researchers say this affects future sea level predictions.
- A study led by Harvard graduate student Natasha Valencic found that building nearly 7,000 dams between 1835 and 2011 shifted Earth's poles by about 1.13 meters.
- This pole movement occurred in two phases: a first surge from 1835 to 1954 in North America and Europe, followed by a second from 1954 to 2011 in Asia and East Africa.
- The dams impounded enough water to cause a cumulative 21.8-millimeter drop in global sea levels and redirected Earth's mass, altering polar positions non-linearly.
- Valencic explained that by capturing water in dams, we reduce the amount of water flowing into the oceans, causing global sea levels to drop, while simultaneously altering how Earth's mass is distributed worldwide.
- These findings highlight significant human impacts on Earth's geophysical properties and suggest such water management must be considered in future sea level and polar motion predictions.

A new study shows that the construction of thousands of dams has shifted the geographical poles of the Earth over the past 200 years. Therefore, according to the research team, no new ice age is threatening - however, it could have consequences for the rise of sea level.
By building thousands of dams around the world, mankind has moved the Earth's rotation axis, and artificial waters also affect sea level.
