CHANGE MITIGATION

OVERVIEW
CLIMATE
Global Climate Change
Definition
Causes
Evidence
Effects
What can we do?

Definition
Climate:
The prevailing or average weather conditions of a place, as determined by the temperature and meteorological changes over a period of years

Causes
Greenhouse Effect
=climate protection
Evidence
CARBON DIOXIDE (CO ) Concentration
2
Important greenhouse gas

Released by natural processes
respiration
volcanic eruptions
Global Surface Temperature

Has increased by about 0.8 degree since 1880 with about two-thirds of the increase occurring since 1980

Arctic Sea Ice
Decreases by a rate of 11.5 percent per decade
From more than 7 million square km in 1980
To about 3.7 million square km in 2012
Land Ice
Land ice sheets in Antarctica and Greenland are losing mass

The continent of Antarctica (left chart) has been losing more than 100 cubic kilometers of ice per year since 2002
Sea Level
Caused by two factors related to global warming:
The added water coming from the melting of land ice
The expansion of sea water as it warms up
Released by human
deforestation
burning fossil fuels
A layer of greenhouse gases (primarily water vapor, and including much smaller amounts of carbon dioxide, methane and nitrous oxide) act as a thermal blanket for the Earth, absorbing heat and warming the surface to a life-supporting average of 15 degrees Celsius.
without greenhouse gases our surface temperature would be minus 18 degrees Celsius.

greenhouse effect is not a bad thing
The role of human activity
Too much greenhouse gases
Global warming
What can we do?
5 ways to reduce your carbon footprint
Green your commute
Be energy efficient
Eat wisely
Trim your waste
Travel green
Consequences
A degree of difference
Effects for Europe:
Increased risk of inland flash floods
More frequent coastal flooding (more storms; sea level rise)
Glacial retreat in mountainous areas
Reduced snow cover and winter tourism
Extensive species losses
Reductions of crop productivity in southern Europe.
Renewable-Energy
78% non renewable energy sources
Renewable-Energy:
Wind
Solar
Geothermal
Water
Biomass
Carbon Footprint (=Ecological Footprint)
Deforestation
IS ONE PLANET ENOUGH?
