Global Warming

The Greenhouse Effect

Carbon Sources and Sinks

QUICK NOTE: FOUND AN AMAZING, SIMPLE, PRESENTATION ON GLOBAL WARMING AND COULD NOT KEEP AWAY FROM SHARING. THIS SHOULD YOU WHEN WRITING YOUR ESSAYS

Love, Ms. Renteria

What is Global Warming? Global warming

refers to the increase in temperature around the world over the last half of the twentieth century.

Class: Can you identify a pattern?

The Greenhouse Effect The Greenhouse Effect

is the process by which certain gases ( water vapour, carbon dioxide, methane and chlorofluorocarbons (CFC’s) ), allow the sun’s short wave radiation to heat up the earth, and trap an ever increasing amount of long- wave radiation from the earth.

The Enhanced Greenhouse Effect Is the increasing amount of greenhouse gases

in the atmosphere as a result of human activities.

Great Video Link!

Carbon Sources and Sinks

SOURCES SINKS

A carbon source is anything that releases more carbon than it absorbs

A carbon sink is anything than absorbs more carbon than it releases

carbon sources- carbon sinks= ???

The Carbon Budget

Carbon Sources

Natural Carbon SourcesHuman Induced Carbon Sources

Volcanic eruptions Wildfires Organic combustion/

decomposition

Burning of fossil fuels Deforestation Reduction in

wetlands

Carbon Sinks

Natural Carbon Sinks What are humans doing to each of these sinks to change their ability to absorb carbon? Why? Plants/ Forests

Oceans Wetlands

Carbon Dioxide Trends

Historical Data (approx.)

1870- 290 ppm
