Explain the distinction between climate & weather. Using this concept, explain why an individual hurricane or summer heat wave is not in of itself proof of global warming? a.
Climateis: a measure of the average pattern of variation in temperature,
humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.
b.
Weather:the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc
c. Individual weather changes does not mean that it was affected by the global climate change. When multiple climate changes around areas changes and causes dominos effect.

Describe several different paths that a parcel of energy might take during its time on Earth and how each one would affect the average surface temperature. You should be able to include interactions with different surfaces, greenhouse and non-greenhouse gases, clouds, and the role of water, and be able to identify the mode of energy transfer at each step.
• Incoming solar energy-‐absorbed by land and ocean 51%, reflected by atmosphere 6%, reflected by clouds 20%, reflected from earth's surface
4%, absorbed by atmosphere 1.6%, absorbed by clouds 3%, conduction and rising air 7%
• (RED) Carried to clouds and atmosphere by latest heat in water vapor
23%, radiation absorbed by atmosphere 15%, radiated directly to space from earth6%, radiated to space from clouds and atmosphere 64%. SEE
ARROW POSITION ON PPOINT
• Considering the Earth from space we can assume thermodynamic equilibrium • At steady state: Energy IN= Energy Out. Climate is hanging in the balance
• Electromagnetic radiation
• Radiation is the transfer of energy by rapid
