Complete Carbon Impact of Long-Distance Travel Exposed

Credit: PixabayThe University of Leeds has revealed the genuine climate impact of long-distance passenger travel in recent research.Although trips over 50 miles (one way) account for less than 3% of all travel by UK residents, they contribute 70% of all passenger travel-related carbon emissions. This disparity is even more pronounced with international travel, which...

Something Strange is Occurring in Earth’s Inner Core

Scientists have proposed that Earth’s moon-sized inner core revolves independently of the mantle and crust, and that it is now backpedaling relative to those other layers.JOHAN63/ISTOCK/GETTY IMAGES PLUSA new study seems to support the contentious idea that the Earth's inner core's rotation has decelerated. Decades of earthquake data indicate that since around 2010, the...
