The ice caps are really getting smaller, not
larger. I saw pictures in Science magazine
that show how much smaller the ice is at the North
Pole, compared with several years ago. The polar
bears are having to go onto land, because there
isn't enough ice for them to live on.
It is confusing, though, because some years the
climate doesn't get any hotter than the year
before. Scientists are finding that there is extra
heat, but it is going into the oceans, which are
big enough to hold a LOT of heat, compared with

about the cycles of the sun, such as sunspots. But
the energy from the sun changes by only a tiny
amount during these sunspot cycles. It was an
