The Giant 3D Printer That Can Stop Climate Change

By Jeremy Radachowsky

In the run-up to the United Nations Climate Change Conference in Paris next month, countries are promoting research into new climate-friendly technologies – things like capturing carbon emitted from smokestacks and storing it underground, increasing efficiency of energy use and the transportation sector, and even wilder ideas such as changing the reflectivity of earth’s surface. Yet, there are two existing technologies that are ready to be acted upon today, whose collective impact could be larger than any future technological breakthrough.

Why World Population Day Matters

In case you hadn’t heard, today is World Population Day and there are now about 7,058,000,000 of us. But what does that number mean?

Climate Change Activists Need To Talk About Population Too

“The environment does not exist as a sphere separate from human actions, ambitions, and needs, and attempts to defend it in isolation from human concerns have given the very word ‘environment’ a connotation of naivety in some political circles.” These words come from the foreword of “Our Common Future: Report of the World Commission on…

Why Nat Geo Exploration Is “Important to us all”

On the occasion of National Geographic making its 10,000th grant for exploration, we interview Peter Raven, chairman of the Committee for Research and Exploration, the Society’s oldest grant-making body. Raven discusses why funding scientific research and exploration has never been more important, especially as the human population has passed the 7,000,000,000 mark, and the planet is pressed hard to meet everyone’s needs.

As Population Tops 7 Billion, Time to Revisit Climate Approaches

The world population reached seven billion people around October 31, according to United Nations estimates. The actual date is a bit fuzzy, but the milestone has nonetheless had great symbolic power, triggering a stream of articles on population issues. Nicholas Kristof, in the New York Times, argued family planning is the solution to many of the world’s ills,…

The Population Monster Knocking at our Door

The United Nations chose today as a “symbolic date” for the the population milestone of 7,000,000,000 people. Today is also Halloween, so the UN chose aptly: Population has been the monster knocking at our door for a long time. National Geographic Senior Environment Editor Robert Kunzig comments that the biggest population problem is not growth, it’s the way we live.

A Scary Arrival on Halloween: the 7 Billionth Human

According to calculations by the United Nations, the earth will gain its 7 billionth inhabitant on October 31st. The 7 billionth child will most likely be born in northern India, a country where half of children under 5 are malnourished and illiteracy is rising.

How Will Lima Slake its Growing Thirst?

Lima is one of the cities of the world most immediately threatened by global warming. The capital of Peru was built on the edge of a desert, one of the driest in the world. And its primary source of water is a small river, the Rimac. The Rimac’s water trickles off glaciers high in the Andes which, unfortunately for Limeños, are rapidly melting. Peru has lost about 30 percent of its glacial ice in the last 40 years.

Will the Human Global Superorganism Secure Our Place in the Universe?

Humans and the planet that gave rise to them are at a number of important crossroads, says writer-thinker Tim Flannery. Will we go down the road that leads to destruction of our civilization and back to an existence of brutality? Or is our destiny the spread of life from Earth into the universe? How much of our fate is up to us?
