Life has prospered
Ice Age

Global Climate
Complex combination of factors.
We don´t yet fully understand.
Supercomputer simulation.Projet future conditon
Cloud and oceans affect.
Greenhouse Effect
Without "Atmosphere"
Global temperature minus 18ºC
Incoming Sunlight strike earths surface.
Part back into space
Rest Trapped in the lower air layer.
Increased heating
+ water evaporate
Feedback
Number of gases
Human
Produce others
Intesify it.
Increase Co2 concentration
2060 twice preindustrial level
2100 four times as high.
CO2: Lifetime 100 tears in atmospher
Methane
Principal Ingrdient of natural gas
Caused 15% warming
Lifetime in atmosphere, 1 decade
Other
Nitrous oxide
Agriculture and industry
Banned
Darming ozono layer
Release tons of carbon
Into atmosphere per year
750 billion already
3 million remain tons in the air
Rest taken by plants, ocean.
Remove 2 Billion tons from atmosphere each year
High co2 fertilizing effect
Commercial artificial indoor atmosphere. With co2
Airborne suspended particles

May help explain the odd mind- century cooling
Models and uncertainly

Equations repreenting known laws of atmospheric
Enough information 100 years ago
Could provide exact description of today
Need powerfull computer
Divide earthsurface into grid
Used property useful tools
Cant solve problem
As the world warms
Warming
More water vapor in air
More rainfall, more intense weather generally
Heat waves more serious
1997 was the hottest
People have contributed to global warning
1860
1860 Planet was still recovering from little ice age
Presat warning might be a continues of that rebound
Critical issues
Temperature shifts
Climate changes keeps rapid
Greenhouse warning will be large ever on geological scale
Anticipating the future
If greenhouse gas emition stop
Warm continues for decades
“Next 10 years will tell”
“We’re going to have to wait”
