“The essence of modern technology starts
human beings upon the way of THAT
revealing through which reality
everywhere, more or less distinctly,
becomes resource”

Degree of climate change
What is happening up to now -- Other
Available observational evidence indicates that regional changes in climate, particularly
increases in temperature, have already affected a diverse set of physical and biological
systems in many parts of the world.
Observed changes include
Shrinkage of glaciers and sea ice
Snow cover has decreased
Thawing of permafrost,
Later freezing and earlier break-up of ice on lakes/rivers
Lengthening of mid- to high-latitude growing seasons
Poleward and altitudinal shifts of plant and animal ranges,
Declines of some plant and animal populations,
Earlier flowering of trees, emergence of insects, and egg-laying in birds
Global average sea level has risen and ocean heat content has increased
Degree of climate change - why is this happening
IPCC (1995) “The balance of evidence suggests a discernible
human influence on global climate.”
IPCC (2001) “Most of the warming of the past 50 years is likely
(>66%) to be attributable to human activities.”
IPCC (2007) ”Most of the observed increase in global average
temperatures since the mid-20th century is very likely (>90%)
due to the observed increase in anthropogenic (human
emission caused) greenhouse gas concentrations.”
Degree of climate change - why is this happening
Some gases, like carbon dioxide (CO), trap heat in the atmosphere by absorbing longwave radiation
while letting the Sun's energy pass through. The transparent roof and walls of a greenhouse allow in
the sunlight while keeping in the heat. Since these gases act similarly in the atmosphere, we call them
greenhouse gases.

Degree of climate change - What is projected
• Less water
Texas in relatively severely affected area
Data / Indicadores de ¿ porque esta pasando?
Degree of climate change - What is projected
• Very likely that heat waves will be more intense, more frequent and longer
lasting
• Precipitation generally increases but with general decreases in the
subtropics
• Precipitation intensity is projected to increase but there would be longer
periods between rainfall events.
• Tendency for drying of mid-continent during summer, indicating a greater
risk of droughts in those regions.
• Sea level projected to rise 1999 and 2099 by 0.18 to 0.59 m.
• Likely increase in hurricane peak wind intensities - an increase in the
numbers of the most intense.
• Fewer mid-latitude storms- poleward shift of storm tracks
• Atlantic Ocean Meridional Overturning Circulation (MOC) – Gulf Stream will
slow down

Situation / el principio precaucionario
“Situations in life often permit no delay; and
when we cannot determine the method which
is certainly best, we must follow the one
which is probably the best… if the method
selected is not indeed a good one, at last the
reasons for selecting it are excellent.”
Rene Descartes quoted by Koen, 2003,

Our current form of economic development is
not sustainable
This situation will likely reach crisis proportions
