The Oceans Flowing Through Our Veins
Nature of ScienceEmpirically based: Based on observationObservation (what we see) vs. Inference
(statements about phenomena that you can’t see)
Subjective: Personal values, agendas and prior experiences
Tentative- scientific claims change as new evidence is made available.
Global Climate Change
Inconvenient Truth Questions How are temperature and carbon dioxide levels in the atmosphere
related?
How is the level of carbon dioxide measured?
What evidence does Gore provide for these effects of rising global temperatures?
What types of impacts could occur as precipitation levels are redistributed?

Kyoto Protocol The Kyoto Protocol is an international agreement
linked to the United Nations Framework Convention on Climate Change. The major feature of the Kyoto Protocol is that it sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions .These amount to an average of five per cent against 1990 levels over the five-year period 2008-2012.
The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February 2005. 184 Parties of the Convention have ratified its Protocol to date. The detailed rules for the implementation of the Protocol were adopted at COP 7 in Marrakesh in 2001, and are called the “Marrakesh Accords.”

Summary: Projected ME Climate Change
Warmer, especially in winter
More precipitation, mainly due to big events
Wetter fall, winter, spring, but less snow
More summer drought

Hydrologic Cycle Terminology
Evaporation: Change of a liquid to a gasTranspiration: Water loss from plants through leaf
poresCondensation: Phase change from water vapor to a
liquidPrecipitation: Atmospheric moisture formed in the air
that falls to the surfaceSurface Runoff: Surface water flow that contributes to
water bodiesMelt runoff: Water movement from melting snow down
into streams and lakesPercolation/Infiltration: The movement of water
during rainfall into the soilGroundwater flow: Subsurface water flow that
contributes to water bodies
