Because it's not about one day, or one cold spell, or one heat wave, or even one winter. It's about the overall trend of temperature over many years. 30 years ago, you never saw your grass in Minnesota this early in the year. 30 years later, the snow is always almost completely gone by the end of March.

Global warming is just that -- global. The measurements involved aren't taken in just one part of the world or another. They're taken from all over the world, including the middle of the oceans, and compared to previous years. The American Midwest, for instance, just had one of its warmest winters on record (and in fact has had measurably warmer winters, on average, over the last decade or more), but global warming doesn't mean everyone's getting hotter all at once. (If we were, we would probably all roast to death in a few years.) While some regions may experience temperatures colder than historically normal from time to time, the overall trend is upwards.
Even many diehard "There ain't no such thing as global warming" advocates are starting to admit that something is causing the world's average temperature to rise. The questions now are "What?" and "What can we do about it?"

That has nothing to do with enviromental issues. The jet stream in the ocean is the main concern. When the earth heats up it will throw us into an ice age.
When Ice burgs drop into a crucial part of the ocean it is a disaster. did you watch the movie the day after tomorrow.
It showed how warm climate can cause the ocean currents to get warm and that is what starts the whole thing moving.
With very little place to stop.

So called global warming in my opinion, is like the gas shortage of the mid-70s, when unscientifically, the so called "experts" proclaimed the world's supply of oil was about to run out. Hysteria, fortified by the media needs no facts. When the powers that be get what they want, global warming will be history. Don't sell your sweaters.

It's global climate change. Not global warming, although, on the grand scale, the average temperature of the earth has risen several degrees over the last few hundred years. Especially this last century.

In spite of some the hysteria, most climate scientists think that the current actual temperature change from man made CO2 is less than a degree. If it weren't for global warming it would have been 41 degrees below zero in stead of just 40 below. They need to show you pictures of polar bears supposedly dieing to tug at your heart strings because reality is not quite so dire.

Global warming is measured using average temperatures, over time. Not just one year. That doesn't necessarily mean it has been caused by humans, though. There have been warming and cooling periods throughout time, and not just since humans inhabited the earth.

Global warming is associated with vast fluctuations in temperatures with a net overall warming effect. So although you can have record cold temperatures in some areas, overall temperatures across the globe are warming on average.

If global warming is happening it is a slow process
Look at Mars, it has global warming and still kept plenty of carbon dioxide ice at its polar caps
That doesn't mean we can't with our slight greenhouse effect

Global warming is done on percentages & stats.
Overall, the entire planet is getting warmer--although we all still have "winter" & summer--but overall--the weather we're experiencing has more highs & more lows than it ever has.
