Yes it has been. A degree may not seem like much, but remember that for just one degree difference a Hurricane can be much stronger or much weaker. The reason is the source of energy is the square of it's surface. Thus one degree multiplied by the space occupied by the Hurricane is tremendous.
Yes, a single degree is a lot. But there may be a solution. However I haven't seen or done any research on the subsequent problems this solution may have in the way of side affects; Seeding the atmosphere with Sulfur Dioxide will cause Ice Crystals which would reflect sunlight away from the earth, thus reducing the amount of heat reaching the earth. While this could offset the greenhouse gas Carbon Dioxide, the only solution to reducing CO2 is to allow nature to dissolve it in the rain. Yes, water vapor dissolves CO2.

Although average global temperature has risen only one and a half degrees in the last hundred years, that seemingly insignificant rise has already dramatically altered climate around the world. Within your lifetime, assuming you're a teenager or a twenty-something, millions and millions of people will suffer and die because of those changes - because global warming is accelerating and it is unlikely the nations of the world, especially the rapidly growing economies like China and India - will cooperate sufficiently to curb greenhouse gas emissions enough to reverse or stop, or even significantly slow global warming.

The source says the air temperature has risen about 8/10 of a degree Celsius (about 1.8 degrees Fahrenheit) since the late 1800s. However I do not really think we know the average temperature of the Earth accurately, because it varies too much from place to place and season to season and depends highly on when and where the temperatures are measured and how the average is computed. I am not even sure air temperature is the right thing to measure. Ground or ocean temperatures are probably more important.

Man-made global warming is about 0.02 C per year.
This is not large compared to the year-to-year variation in overall average global temperature, which is about 0.09C standard deviation. Nevertheless, the signal is quite clear over the course of the 20th century. Some malicious people are willing to say that man-made global warming does not occur, and are willing to confuse the issue in order to further their political agenda.

The last measurement had it rising 1 degree in the last 125 years.

Temperature is rising, an average of one degree across the whole planet above the usual temperature at our current cycle.
Remember, it is an average, some places don't appear to change, some places get colder, colder then hotter, hotter than colder, and just plain hotter.

The ice age ended 15,000 years ago because of global warming caused by all those cavemen running their backyard barbeques, driving all those SUV yaks around, and all those prehistoric lawn mowers. It's time they stopped!

Our earts heat 14 C. Changing this temparature (+ or -) is weary dengerus for all creatures.

The last ice age ended 15,000 years ago, so there must have been global warming. Why?
