I recently talked about skepticism. A recent news release illustrates what I mean.
The story is here.
My summary is this. Scientists found leaks in the magnetic field that surrounds Earth, protecting it from the solar wind.
The new observations "overturn the way that we understand how the sun's magnetic field interacts with the Earth's magnetic field," said David Sibeck of NASA's Goddard Space Flight Center in Greenbelt, Md., during a press conference today at the annual meeting of the American Geophysical Union in San Francisco.
Al Gore should take note that sometimes we do not know what we thought we knew.
