Ice is less dense the
water! So when it melts ice
contracts! This is why the freezing
central heating systems crack central heating radiators are open. He ice expands as increases!
The arctic seas go down to -20°
C. The maximum density of water is at 3°
C. So as ice melts and nose into the
seas, it really contracts! Three years ago
air we had an Antarctic ice maximum!
For last 200 years global
photosynthesis has limited free daytime carbon dioxide levels in the air at
only two parts per million! Burning of
fossil fuels has increased active life on earth. It is not affected the gas composition of the
air.
This is O level physics and
biology!
