Apparently being a lawyer(?) doesn't ensure any real intelligence or being in possession of a well-rounded education. Global warming refers to the overall mean temperature. First, there are the major changes that have already occurred as a result of these seemingly small temperature variations. A recent global event indicator was the 1997-1998 El Niño phenomenon. Even the small temperature changes that have already occurred have been blamed for the increase in frequency and severity of the El Niño phenomenon, which is now every 3-5 years instead of the previous cycle of every 5-7 years. Archaeological studies show that El Niños have been occurring naturally for thousands of years. However, the frequency and severity are believed to be increasing as the global warming continues (see graph below courtesy: NOAA/University of Colorado at Boulder). The 1997-1998 El Niño event alone had enormous impact on many areas around the globe, causing thousands of human casualties and destruction adding up to over $90 billion in damage worldwide (United Nations Environment Programme, 2002), with the poor in developing countries suffering the greatest losses.
Secondly there is the part question as to how fast these changes will occur. Most predictions of global warming are based upon the assumption that the increase in greenhouse gases will result in a gradual change in global temperatures that will, in turn, cause slow changes in our weather patterns. The majority of environmental and economic scenarios and assumed effects are being based upon this slow change assumption. There are, however, several recent studies which show that the global temperature has and may again, change very quickly. "Available evidence suggests that abrupt climate changes are not only possible but likely in the future, potentially with large impacts on ecosystems and societies.” (US National Academy of Sciences [NAS],2002). This has given rise to more focused research into likely causes of abrupt or sudden events, especially the role of important processes such as the ocean's "thermohaline circulation" so named from the Greek words “thermos” (heat) and “halos” (salt).

What this means, ray, is that the individual cold/snowy/warm day does not effect the overall trend in warming temperatures over a year or even a decade.
