Radiation Traces a Complex Path
Experts hesitate to predict where Fukushima's radiation will go because its travel patterns are as mercurial as the weather and as complicated as the food chains along which they move.
Evidence of radiation contamination from the nuclear reactor in Fukushima, Japan is showing up in milk and spinach, but scientists' predictive capacities have been left wanting. "When and where radioactive contamination becomes a problem depends on a vast array of factors: the specific element released, which way the wind is blowing, whether rain will bring suspended radioactivity to earth, and what types of crops and animals are in an exposed area. Research related to the 1986 Chernobyl accident makes clear that for decades, scientists will be able to detect the presence of radioactive particles released by the crippled Japanese reactors thousands of miles away."
It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.
- SpaceX launched Falcon Heavy into space early Tuesday morning.
- A part of its nosecone – known as a fairing – descended back to Earth using special parachutes.
- A net-outfitted boat in the Atlantic Ocean successfully caught the reusable fairing, likely saving the company millions of dollars.
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
The world's richest people could breeze through a climate disaster – for a price.
- A new report from a United Nation expert warns that an over-reliance on the private sector to mitigate climate change could cause a "climate apartheid."
- The report criticizes several countries, including the U.S., for taking "short-sighted steps in the wrong direction."
- The world's poorest populations are most vulnerable to climate change even though they generally contribute the least to global emissions.
