We recommend the reports from the Intergovernmental Panel on Climate Change (IPCC). The IPCC was established in 1988 to examine the most current scientific information on global warming and climate change. The IPCC does not carry out research.

Two 19th-century scientists are associated with the discovery that increasing carbon dioxide in the atmosphere warms the entire planet: French researcher Jean Baptiste Fourier and Swedish scientist Svante Arrhenius. Their identification of what came to be called the greenhouse effect (see box at right) applies to both natural and human-produced additions of CO2.

Effects are already visible in every ecosystem: coral bleaching, changes in flowering seasons, changes in bird and insect and mammal and fish migrations, melting of glaciers, thinning of polar ice caps, disappearance of cloud forests, warming of groundwater, changes in tree ting thickness, etc.

This is a matter of considerable speculation in the climate research community. It is plausible that a warmer earth would produce more and stronger El Ninos. There is some evidence that the earth has warmed over the past two decades, and there is no doubt that El Nino has been much more frequent in that time.

There are always cold spells and warm spells going on in one place or another. But even where weather is cold, what's considered "typical" is changing. For example, the heavy snow that struck Colorado and Kansas at the end of 2006 was actually more characteristic of that area's autumn or spring weather than a typical December. To examine long-term warming, climate scientists look at large areas and longer time periods. The maps below help illustrate the global nature of climate change.

The jury is still out on this. Are we likely to see more El Niños because of global warming? Will they be more intense? These are the main research questions facing the science community today. Research will help us separate the natural climate variability from any trends due to man's activities. We cannot figure out the "fingerprint" of global warming if we cannot sort out what the natural variability does.

Only [a] few abstracts explicitly reject or doubt the AGW (anthropogenic global warming) consensus which is why I have publicly withdrawn this point of my critique.” And when we pressed him to provide the names of the articles, he eventually conceded - there was only one.

The clinical results come from the medical and scientific literature and announcements and abstracts presented at oncology meetings and oncological symposiums. All of the source information is written by oncologists and other doctors who treat cancer patients at leading hospitals and medical centers in the U.S. and around the world. Cancer Monthly finds, organizes, and summarizes the information published by the doctors who provided the treatment.

Experts agree and tests have proven, the most effective repellents on the market contain DEET and those without it do not provide the same protection from insect bites. Using a non-DEET product could mean that users are at greater risk for bites. DEET has a 45-year track record of reliable use and extensive scientific study, while much less is known about alternatives.

That would be the CIMS Directory, published annually in October. It contains information on mail services, office services, the library, and various faculty committees, as well as contact information for everyone in the building. There should be a copy in every office, but if not they can be obtained from Larry Cohen in Room 905. It is very important that you keep your contact information up to date in the directory. Forms go out in September to give everyone an opportunity to do exactly that.
