Greenhouse Gases, Global Warming and Climate Change

IF

CARBON SINK = CARBON SOURCE,

THEN THE CONCENTRATION OF THIS GREENHOUSE GAS IN

THE

ATMOSPHERE

REMAINS STABLE

-Greenhouse gases emitted by human activity influences global climate

-Average global temperature increased by 0.47 degrees Celsius between 1880 and 2008

Greenland Ice - Core Project

Human activities contribute to global warming

Anthropogenic greenhouse effect: is the enhancement of the natural greenhouse effect due to increased greenhouse gas emissions caused by human activities

Increasing Greenhouse

Gas Emissions

Climate Change Bibliography

Carbon sink is any process that takes carbon dioxide from the atmosphere and store it

EXAMPLE: PHOTOSYNTHESIS

Wasn`t that

SUPER

  • Operates on Greenland's Continental Glacier
  • Ice is like wood
  • Carbon Dioxide Gas is on the move

A carbon source is any process that releases carbon dioxide to the atmosphere

EXAMPLE: fossil fuels

8.1 Anthropogenic Greenhouse Effect

A Global Problem

History of greenhouse gas research

IPCC (Intergovernmental Panel on Climate Change) is a group of world leading scientists that attempt to solve this problem

-1861 first discovered different gases absorbed infrared radiation differently

They said: "If we continue to produce such high levels of greenhouse gases, Earth will experience even more traumatic weather conditions."

-20th century climatologist noticed the rise of average global temperature

Greenhouse gases produced by human activities

-industry

-electricity generation

-transportation

-agriculture

Global Warming

Measuring greenhouse gases

Global warming potential: measure of the ability for a gas to trap thermal energy in the atmosphere

Persistence: is the length of time the gas remains in the atmosphere
