Sabotaging the Climate Change Debate

Question: To this day, there are people who do not accept that we are influencing the environment on a planetary scale. Why do you think there are still people who hold out on this question? 

Gro Harlem Brundtland: Well, you know, in a way it is surprising that it has been possible for strong influential sectors, or even companies or groups of companies to make such an impact in undermining or countering the scientific evidence that has been mounting. So, a lot of effort has gone in to try to undermine reality. Now why is it being listened to? This is hard to understand, but the fact of the matter is that a lot of resources, a lot of thinking and a lot of money has gone into trying to influence the world in a negative way. And this is, well we have the same issue with the tobacco companies if we go back -- well it's not over, but at least it became clear to many that the tobacco companies in fact were misbehaving, lying to the U.S. Congress and putting a lot of effort into undermining public health efforts. So, I think we have an aspect of this also with regard to climate change.

Skeptics of global warming present the same issue as tobacco companies who misbehaved, lied to Congress and undermined public health efforts.

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.

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.
