One Wobbly Thing: The Earth’s Shifting Axis

A study published recently in the journal Geophysical Research Letters found that the Earth’s axis, which shifts naturally, is now shifting 17 times faster than before 1981. Scientists use satellites that track gravity to assess “polar drift” and what they have discovered is that water is the greatest cause of the shifts.  Even more unnerving […]

Google Unveils 37 Year Time-lapse of Earth’s Surface, Reveals Melting Glaciers, Deforestation

In time for Earth Day, last week Google unveiled Google Earth Timelapse, allowing users to see zoomable videos documenting how the Earth has changed since 1984. Through the eyes of a satellite, users can view sobering and sometimes alarming trends of deforestation, sea-level rise, dried up seas, and urban sprawl. 

Why This Matters: The world is fast approaching its deadline to stop global temperature rise and prevent total climate catastrophe, but in the U.S., the world’s second-largest emissions producer, some politicians are still fighting the climate efforts to control emissions.

Using Satellites to Track Carbon Emissions Is On the Horizon

By Ashira Morris, ODP Staff Writer

Soon it will be possible to precisely track carbon emissions anywhere on the planet by satellite.  Carbon Mapper, a new nonprofit, plans to launch its first two satellites in 2023, which they hope will be joined by a “constellation” of other satellites two years later. 

Why This Matters: These satellites would be able to detect methane and carbon emissions, giving people a potent tool to hold emitters accountable — just like pollution monitors on the ground might.
