8 Great TED Talks to Teach Students about Climate Change

8 Great TED Talks to Teach Students about Climate Change | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

While climate change is a hotly debated topic especially in mainstream media yet a lot of people are not well aware of its deep implications on the life of species on the planet earth. The major part of climate change is caused by human activity (e.g pollution, deforestation, burning fossil fuels…etc) leading thus to a huge increase  in the release of carbon dioxide into the atmosphere. The result: unexpected change of weather patterns with an unusual global warming.

How Eratosthenes calculated the Earth's circumference

"In the mid-20th century we began launching satellites into space that would help us determine the exact circumference of the Earth: 40,030 km. But over 2000 years earlier, a man in Ancient Greece came up with nearly the exact same figure using just a stick and his brain."

Seth Dixon's curator insight, November 1, 1:19 PM

Eratosthenes is often referred to as the "father of geography" for creating meridians and parallels on his maps to organize global information, classifying climatic zones, and as shown in the video, calculating the circumference of the Earth. Plus, he coined the terms so he gets the credit. If you have never pondered the meaning of the word "geometry," the accomplishments of Eratosthenes will certainly show that the mathematical prowess was at the heart of expanding our collective geographic knowledge (additionally, here is a retro Carl Sagan in a video clip from Cosmos that inspired this clip).

Growth of underwater cables that power the web

Growth of underwater cables that power the web | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

"The map above, created with data from Telegeography, shows how those cables have developed since 1990. Most existing cables were constructed during a period of rapid growth in the mid-2000’s. This was followed by a gap of several years during which companies steadily exhausted the available capacity. Over the last few years, explosive new demand, driven by streaming video, has once again jumpstarted the the construction of new cables."

Four maps that explain the chaos of the Middle East

Four maps that explain the chaos of the Middle East | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

"Without trying to defend or absolve U.S. policy, then, it is worth stepping back to ask what shared historical experiences might have left these four countries — Iraq, Syria, Libya and Yemen — particularly at risk of violent collapse. The following maps help highlight how, at various points over the past century, historical circumstances conspired, in an often self-reinforcing way, to bolster the stability of some states in the region while undermining that of others."

These maps are not cartographically inspiring, but the it's the historical and political insight that makes them valuable. The goal of this set of maps is to find some underlying causal reasons for political stability(or more importantly instability) in the Middle East. These four maps focus on these key issues:

1. Century-old states are more stable today

2. Colonial rule led to fragile states

3. Instability and regime change

4. The shadow of the Cold War

Mekong Delta fights losing battle against salt water

Vietnam's rice region is facing the worst drought to date. Over half a million people have been affected, and the country could lose one million tons of its staple food.Leaders of six countries along the Mekong River met in China to discuss the relief measures.

Seth Dixon's curator insight, August 18, 2:49 PM

Economic progress for some often entails job loss and environmental degradation for others.  As dams upstream are slowing the flow of the Mekong River, the low-lying delta that is a rich agricultural region is facing the ocean water that is moving further inland.  The once isolated and remote Mekong is experiencing some impacts of globalization.

Thanksgiving: Fact or Fiction | HISTORY.com | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

“The reason that we have so many myths associated with Thanksgiving is that it is an invented tradition. It doesn’t originate in any one event. It is based on the New England puritan Thanksgiving, which is a religious Thanksgiving, and the traditional harvest celebrations of England and New England and maybe other ideas like commemorating the pilgrims. All of these have been gathered together and transformed into something different from the original parts.”

This is nothing new to most visitors to this site, but every four years we have a wonderful teaching moment to show how population density can change our interpretation of a map and the meaning of the data embedded in that map.  In preparation for next week, this article for the Washington Post as well as this one from the New York Times should help get students be better prepared for the onslaught of maps that we know are right around the corner, to properly assess and contextualize the geographic content in these maps.

Norka McAlister's curator insight, April 5, 2015 8:01 PM

Citizens of Syria have experienced difficult times since their country entered into a period of continual war in the past few decades. People migrate to Europe in demand of better life for their families. All begin with a plan and a &helper,&  called trafficker or coyote in Mexico, and money to cross few borders and be able to live life free from war. Although, with countries such as Egypt, Lybia, Lebanon, Turkey, and Greece, with a massive migrations, tough economies, lack of jobs, nothing and no one is safe. However, Europe is very attractive in terms of quality life and safety to raise families. Furthermore, to be able to survive during this migration transition, many risks are involved and even in some cases, killings. Immigrants migrate by boat, truck, train, and sometimes even walking. Day or night immigrants keep moving and pay  high prices to be transported to the next point. It takes them weeks, months, and even years to reach thier final destinations. This is the same for those immigrants in Mexico and U.S.

What's the tallest mountain on Earth?

What's the tallest mountain on Earth? | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

"Mount Everest is usually said to be the highest mountain on Earth. Reaching 29,035 feet at its summit, Everest is indeed the highest point above global mean sea level—the average level for the ocean surface from which elevations are measured. But the summit of Mt. Everest is not the farthest point from Earth’s center.

Earth is not a perfect sphere, but is a bit thicker at the Equator due to the centrifugal force created by the planet’s constant rotation. Because of this, the highest point above Earth’s center is the peak of Ecuador’s Mount Chimborazo, located just one degree south of the Equator where Earth’s bulge is greatest. The summit of Chimborazo is 20,564 feet above sea level. However, due to the Earth’s bulge, the summit of Chimborazo is over 6,560 feet farther from the center of the Earth than Everest’s peak. That makes Chimborazo the closest point on Earth to the stars.  

You may be surprised to learn that Everest is not the tallest mountain on Earth, either. That honor belongs to Mauna Kea, a volcano on the Big Island of Hawaii. Mauna Kea originates deep beneath the Pacific Ocean, and rises more than 32,800 feet from base to peak."

I've tried to answer this question without any visual aids and there is always at least one confused look in the class.  This infographic is the most straightforward way to give the 'long' answer to a seemingly simple question, "what is the tallest mountain on Earth?"  It all depends on how you measure it and what your reference point is.
