Bloomberg interactive graph "What is really warming the world ? "

This interactive feature shows graphs corresponding to different factors

They include influence of sun, changes in earth's orbit, volcanoes, etc.,

You see that predicted warming due to CO2 increase matches most closely with rise in temperature

The correlation coefficient tells you, in a certain sense, how closely two sets of data match.

ASSIGNMENT 9

Do problems 1,4 and 17 from exercise 1.10. Also draw a graph of C (CO2 concentration) as a function of Delta F.

[Hint: For drawing the graph use the equation of C in terms of Delta F that we got in class by solving for C in the equation of the Greenhouse Law of Arrhenius; For problem 4 to answer the question about methane you can mention the release of methane from the permafrost in places like Alaska and Siberia as the ice thaws due to warming].

Assignments 6 and 7 were due monday but you can still bring them on wednesday (tomorrow). Assignment 8 is due tomorrow.

If you need help please talk to me asap. I am in my office from 11 to 4.30 MWF (except when I am teaching) and 11 to 1 on Thu.

Tomorrow we will continue with section 1.9 (Greenhouse law).

Video we watched in class today, about world's oil future

This video is about the variation in oil production in time, which is the topic of assignment 7

Assignment 8, based on exercise 1.7 of text and articles below

Practice problems on logarithms are on webwork. Only for practice, not for submitting or for grades. Go to webwork.howard.edu and click on the class named MATH-012mcgowan. There are 2 homework assignments. 00Introduction just teaches you to use webwork. Logarithms gives you some practice in logs. Your user name is first initial & last name (all lower case, all one word), with one exception. Anthony Cooper's user name is ancooper, and Adam Cooper is acooper. Password is the student ID without the "@" sign, but with the initial zero. If you have trouble see Dr. McGowan.
