CLIMATE CHANGE
WEATHER VS CLIMATE
-
WEATHER: refers specifically to the environmental conditions that occur at a particular place at a particular time
-
-
HEAT TRANSFER
CONDUCTION - transfer of thermal energy through direct between the particles of a substance without moving the particles to a new location
CONVECTION - the transfer of thermal energy through the movement of particles from one location to another
-
WINDS
-
Air Circulation
Jet streams are a result of convention currents + Coriolis effect. they affect the formation of severe weather events, and affect the movement of the air at lower levels of the atosphere
Global winds transfers thermal energy from area of net radiation budget surplus to areas with a net radiation budget deficit
-
Oceanic Circulation
-
Deep ocean currents - known as the global ocean conveyer belt "constantly moving system of deep ocean circulation driven temperature & salinity"
-
KEY FINDINGS
-
CO2 is at an "unexpected" level not seen for at least 800,000 years
-
over the last 2 decades, Greenland & Antarctic ice sheets have been melting & glaciers recede in most parts of the world
