Back in 2009, at the United Nations (UN) Framework Convention on Climate Change, nations around the world drew a hypothetical line in the sand, pledging to do everything in their power to prevent
the world annual average temperature from warming an additional two degrees Celsius (3.6 °F)- known as the Copenhagen Accord.

The
average annual temperature at Plateau Station in central East Antarctica is -57 Centigrade (according to my National Geographic Atlas of the
World, 7th Edition).
Most areas of the
world experienced above -
average annual temperatures, as indicated by the
Temperature Percentiles map below.
Hidden within
annual averages and expected variability are startling instances of new
temperature and rainfall records in many parts of the
world.
Hidden within
annual averages and expected variability are startling instances of new
temperature and rainfall records in many parts of the
world — weather extremes that would once be considered anomalies but that now risk becoming the new norm as the Earth heats up.
«Between 1961 and 1990, the
annual average temperature for the globe was around 57.2 °F (14.0 °C), according to the
World Meteorological Organization.»
The polar regions are particularly sensitive to small rises in the
annual average temperature, they are sometimes referred to as «the canary in the coalmine» in that they show changes long before they can be seen elsewhere in the
world.
Record droughts in many areas of the
world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on
annual variablity (no bets on what happens next year, but the five - to - ten year
average in global
temperatures, sea surface
temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.
So, for example, the results suggest that
annual hottest daytime
temperatures in the Mediterranean would be 2C higher in a
world that was, on
average, 1.4 C warmer.
You can see this in the figure below, which maps projected changes in
annual average temperature in a 2C warmer
world.
