Listenwise: Climate Change and Human Migration

Listenwise

From Listenwise  --  Migration has been a huge part of human history. Experts agree that early humans started out in Africa and began to migrate out of Africa to different parts of Europe and Asia around 100,000 years ago. This migration occurred in waves but we don’t know why early humans left Africa. Recent research supports the theory that climate change may have been the force that drove early humans out.

EARTH: Sand Shouldn't Stand In for Volcanic Ash in Jet Engine Tests

EARTH Magazine

From EARTH Magazine, August 10, 2016  --  In 2010, trans-Atlantic airspace was shutdown, and international travel halted, when Iceland's Eyjafjallajökull erupted, spewing ash into the air. This was an expensive decision, triggered by the threat ash posed to aircraft, crews and passengers. When ash enters an aircraft turbine, which typically can reach temperatures of up to 2,000 degrees Celsius, the ash can melt, damaging the engines in midflight. 

Press release for students - Half a degree makes a world of difference

EGU Planet Press

From EGU, April 21, 2016  --  The climate of our planet is changing, and the Earth is warming up. World leaders have discussed whether we should limit the average temperature increase in our planet to 1.5°C or 2°C. There’s only half a degree of difference between these two temperature limits, but scientists have now discovered that they would each have very different consequences for our planet.

EARTH Magazine: Did the Medieval Warm Period Welcome Vikings to Greenland?

EARTH Magazine

From EARTH Magazine, May 16, 2016  --  What is known: Vikings sailed to Greenland. They homesteaded there for a few hundred years, and likely experienced multiple famines. Many died. Some returned to European shores. And all of this happened during a time in Europe known to geoscientists as the Medieval Warm Period. The warmer, milder conditions that defined this time eventually ended too.
