The phrase ‘global warming’ denotes not only the increase in the 
Earth’s  average  temperature  (Figure 5.8),  usually  measured  as  the 
average temperature per year, but also substantial changes in the 
entire climate system.

(1961–1990) (°C) 
The climate in the Baltic countries has become warmer over 
the last years. Winters have become shorter and the snow cover 
thinner. The warm period has become longer, and there are fewer 
days with low temperatures. The average temperature on the planet 
has  increased  for  approximately  0.7  ±  0.2 °C  (Figure 5.9).  Long 
periods of draught occur in summers. Air warming takes place not 
only over the continents but also over the seas and oceans. With the
