Textbook’s Take on Climate ChangeCarl Wolk

Thu, 20 Nov 2008 08:08:12 +0000

“Even more controversial is global warming, which some scientists believe results from the carbon dioxide emissions.  The Earth’s average temperature has increased over the past 100 years, but most of the increase occured before 1940.  Determining what causes changes in the earth’s temperature and isolating the effect of carbon dioxide from other factors are proving […]

A Better Look at Temperature TrendsCarl Wolktemperature-trend-data

Sun, 02 Nov 2008 04:00:08 +0000

In the graph below, the temperature value for a certain month is the trend from that month to the present.  The data ends in 2003 (earlier for the Tropics) for ease of viewing (As we approach the current month, trends become increasingly large in magnitude).

New BlogCarl Wolk

Mon, 27 Oct 2008 05:00:52 +0000

I’ve started a new blog with Australian winemaker and climate expert Erl Happ.  It can be found here: I’ll still be posting here, though possibly less frequently.

RSS Anomoly GuessCarl Wolkrss-uahprediction-graph

Mon, 06 Oct 2008 17:53:32 +0000

September’s numbers are out from University of Huntsville, and global temperatures rose slightly. RSS hasn’t released their data yet, but I’m going to guess that their anomoly will be around 0.25 degrees C (+/- 0.04 C).  This could turn out to be innacurate, but we’ll have to wait to see.  This isn’t a wild […]

Update on UAH/RSS DifferenceCarl Wolk

Fri, 03 Oct 2008 18:30:12 +0000

A while ago, I posted on the annual cycle in the difference between UAH and RSS. Looks like Lucia, Atmoz, and McIntyre beat me to it by a few months.  Here’s a post on Lucia’s Blackboard with a little more statistical sophistication than mine; note the discussion in the comments.

Alaskan Climate ChangeCarl Wolkimg13234

“Well, as the nation’s only Arctic state and being the governor of that state, Alaska feels and sees impacts of climate change more so than any other state. And we know that it’s real.” -Palin during the VP debate. Here’s a graph of sea surface temperatures around Alaska: It is apparent that the great climate […]

Cirrus Cloud Distribution During the 1997/98 El NinoCarl WolkClick to play El Nino & Cirrus Cloudpacific-nino-sst

Make a Smilebox slideshow I made the slideshow above so that I could see if cirrus cloud distribution behaved signifcantly differently during the large El Nino of 1997/98. Below is a graph showing the progression of the El Nino in the Pacific. In the Pacific, it is apparent that there was (for the season) a […]

Inter-Annual Fluctuations in Cirrus Cloud CoverCarl WolkClick to play Cirrus Cloud over 1 year

Sat, 27 Sep 2008 05:15:43 +0000

  Make a Smilebox slideshow The above slideshow is intended to show how cirrus cloud distribution changes each year.  I am chieflyconcerned with the tropical regions. Cirrus clouds have a yearly path Northwards and then Southwards.  From January to March, cirrus clouds are maintained South.  From April to June, they move North.  From July to […]

Cirrus Cloud and the 1997/1998 El NinoCarl Wolkoct-1996img000008el-nino-tempmean-october1

One assertion made by Erl Happ’s theory of climate is that changes in cirrus cloud cover create tropical warming events (El Ninos).  Cirrus cloud is a cause of albedo, reflecting sunlight back into space.  Therefore, less cirrus cloud would lead to a warming event, while more cirrus cloud would lead to a cooling event. After […]
