Presentation Transcript


Global Climate Change: Detection and Attribution

  • Finish Idealized Global Circulation Model and Global Climates

  • Is the Current Climate Changing?

  • If so, on what evidence?

  • Why?

    Exam I on Feb 5! Review Sheet is Posted.


Where the Hell is Matt?

June–July ITCZ

Seasonal Patterns

Location of the sun’s noon-time vertical rays (i.e., where the sun is directly overhead) helps to control the position of the ITCZ

Northern Hemisphere summer, ITCZ and all of the wind and pressure belts migrate to the north

North Hemisphere winter, ITCZ and all of the wind and pressure belts migrate to the south

Climate Change Detection

  • Is the Earth’s Current Climate Changing?

  • If so, what evidence can you provide?

  • (We will discuss the question of attribution in a bit.)


YES!

YES!


Linear Trend of Annual Temperatures


Observed Variations in the Cryosphere


Time Series of

Cryospheric Change:

1950-2005

Cryosphere has exhibited

significant changes since 1950,

particularly in the northern

hemisphere.

Climate Change Attribution

  • Why is the climate changing?


What are some Anthropogenic Influences on Climate?


What are some Anthropogenic Influences on Climate?

  • Greenhouse gases

  • Aerosols – suspended particulates

  • Land use/land cover change

Natural Forcings?

  • Solar Irradiance

  • Volcanoes

  • Changes in Oceanic and Atmospheric Circulation


No denying that the anthropogenic

warming is playing a role:

Question is how much?
