From EARTH Magazine, 03/04/2015 -- Children born during, and up to three years after, the devastating 1997-1998 El Niño event in northern Peru were found to be shorter than their peers in a new study covered in EARTH Magazine. The rising waters wiped out crops, drowned livestock, cut off bridges, and caused prolonged famine in many rural villages. Now, a new study that tracked long-term health impacts on children from the affected region has found that a decade later, the children continue to bear signs of the hardship endured early in their lives.
From EARTH Magazine -- Hurricane Sandy struck the U.S. East Coast in October 2012, leaving about $65 billion of damage in its wake and raising the question of how to mitigate the damage from future storms. It's a question that arises in the wake of most natural disasters: What steps can society take to protect itself from storms, floods, landslides, earthquakes, tsunamis or volcanic eruptions? But the question itself illustrates the complexity of preparing for natural disasters.
From EARTH Magazine -- On March 13, 1989, a geomagnetic storm spawned by a solar outburst struck Earth, triggering instabilities in the electric-power grid that serves much of eastern Canada and the U.S. The storm led to blackouts for more than 6 million customers and caused tens of millions of dollars in damages and economic losses. More than 25 years later, the possibility of another such catastrophe still looms, and the day-to-day effects of space weather on electrical systems remain difficult to quantify.
From EARTH Magazine -- When large earthquakes hit Earth in quick succession, many people wonder if the events are linked. Scientists generally say that such events aren't linked, but the latest research seems to indicate that a large earthquake can potentially trigger another quake hundreds or even thousands of kilometers away in a process called dynamic triggering. However, when it could happen is far from predictable.
This story, about the discovery of ancient cave paintings in Indonesia would be a great starting point for a discussion of human origins and geology. Cave painting has long been thought to be developed by early humans in Europe. This discovery in Indonesia is pushing scientists to look even farther back to our human origins in Africa.
From EARTH Magazine -- When Francisco Pizarro landed in Peru in 1532, his band of Spanish conquistadors set off a chain of far-reaching consequences for the people and economics of western South America. The Chira Beach-Ridge Plain in northwestern Peru is rippled by a set of nine ridges — several meters tall by up to 300 meters wide and 40 kilometers long, and large enough to be visible from space — running parallel to the shoreline. The pattern, observed along at least five other Peruvian beaches, was thought to have formed naturally over the past 5,000 years.
Nearly two years ago Hurricane Sandy devastated communities on the New Jersey coast, leaving governments, scientists, architects, and citizens looking for innovative solutions to protect against natural disasters. This public radio story looks at the design and thinking behind the New Meadowlands Project in New Jersey. From the appeal of a new Central Park, to the protection wetlands provide neighboring communities from flooding, this story will get your students thinking about the benefits and challenges of implementing big environmental protection projects.
This story, about the discovery of a long lost ship, is a fascinating way to discuss early exploration efforts as well as global warming. In 1845 two ships led by Sir John Franklin left England searching for a northern route across the globe, known as the Northwest Passage. They never returned. 169 years later, a helicopter pilot found a clue that led the Canadian government to one of the missing ships. From sonar imaging to video cameras on submarines, archeologists have confirmed that this is one of the abandoned ships from the famous expedition.
In the last century the coastline of Louisiana’s Lower Mississippi Delta has experienced an enormous loss of land. From man made levees, to hurricanes, to oil spills the coastline and it’s communities have been negatively affected. In today’s public radio story as we hear from a fishing guide who has lived and worked in the area for 34 years. Listen to learn more about the societal impact of coastal erosion.
