Nature of Science
 Empirically based: Based on observation
 Observation (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.”

Participation in the Kyoto Protocol, where dark green indicates countries
that have signed and ratified the treaty, yellow is signed, but not yet
ratified, grey is not yet decided and red is no intention of ratifying.
Kyoto expires 2012 next international conference on Global
Climate Change to occur in Bali.

Evaporation: Change of a liquid to a gas
Transpiration: Water loss from plants through leaf pores
Condensation: Phase change from water vapor to a liquid
Precipitation: Atmospheric moisture formed in the air that falls
to the surface
Surface Runoff: Surface water flow that contributes to water
bodies
Melt runoff: Water movement from melting snow down into
streams and lakes
Percolation/Infiltration: The movement of water during rainfall
into the soil
Groundwater flow: Subsurface water flow that contributes to
water bodies
