In 2007, Climate Change Falls Short of Top 20 Public Issues


Pew has released its annual analysis of the top 20 most followed news stories of the year by the public. Pew pairs the survey data with a summary of their weekly news agenda tracking. For regular readers of this blog, you should not be surprised that climate change fails to crack the top 20 most followed issues or the top 20 most covered topics of 2007. (See previous posts here, and here.)


Several issues appear in the top 20 agenda items that are incidental to climate change including gas prices, periodic heat or cold waves, wild fires, and even the economy. In terms of effective public communication, if you are going to raise the public profile of climate change, one challenge is to figure out how to meaningfully and accurately connect the dots on these other agenda items, drawing attention to climate change by "riding piggyback" on focusing events.

One possible strategy is for scientists and environmental groups to put carefully vetted crisis communication plans in place so when wild fires, heat waves, skyrocketing gas prices, or other focusing events occur, each group can communicate in an accurate and coordinated way about the relevance of global climate change.

For example, when the wild fires hit California earlier this year, the event could have served as a major opportunity for environmental groups to engage the public. Yet their efforts were either paralyzed or off target because of a lack of careful and thorough research and planning about exactly what the message should be and how to communicate the message in a coordinated and consistent way.

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
