The global warming debate:

earth temperature from satellite observations
global warming has happened in the past through natural cycles
not enough evidence that it is human caused and serious enough to worry about
what is happening in one place may not reflect the whole globe
not the most serious issue for us today
dubious of the use politicians are making of the issue

STS approach:
is this an issue that requires action
some people think it does
where are they coming from?
prediction including human action

without human causation
