About this course (1)
Interactive because:
• research shows people learn more if they
are actively involved
• it's more sociable
• you can share knowledge

Let’s find out about you!
How much do you agree?
• Climate change is happening.
• People are at least partly responsible for
climate change.
Give a number between 1 and 10
10 means: I completely agree
1 means: I completely disagree

Energy efficiency
Which is most efficient?
Look at the handout in pairs
• Rank from 1 – 10 with 1 being least energy
efficient and 10 being most efficient
Week 1: it’s happening!
•Climate scientists are agreed that climate
change is happening
•We are already seeing changes in nature
•Anthropogenic carbon emissions are at least
partially responsible
•We can take action but it will take substantial
international action
• We need to act fast

Observed Changes in the Climate System (1/2)
Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are
unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of
snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have
increased.
Understanding the Climate System and its Recent Changes (1/1)
Human influence on the climate system is clear. This is evident from the increasing greenhouse gas
concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of
the climate system.
Future Global and Regional Climate Change (1/2)
Continued emissions of greenhouse gases will cause further warming and changes in all components
of the climate system. Limiting climate change will require substantial and sustained reductions of
greenhouse gas emissions.
