Global warming refers to the rise in average global temperatures since the beginning of the Industrial Age and particularly since about 1970. Scientists tell us that is is the result of increased greenhouse gases in the atmosphere, resulting from human activity, particularly from burning coal, oil and natural gas, as well as from deforestation and the manufacture of cement. The extent of global warming during the twentieth century is about 0.75 degrees Celsius, with a much higher increase predicted for this century.
We need to remind ourselves that global warming is not something benign that will mean nice warm winters and glorious summers. It will mean climate change, with prolonged droughts in some areas, more frequent floods in others, loss of productive coastal land, displacement of some entire populations and more frequent sever storm activity. There will be a loss of food production that can not be made up for by opening up arctic areas. The year 2010 had the warmest global average temperature on record, fractionally warmer than 2005 and 1998, but as the difference is slight, the three years are regarded as the equal hottest. The past decade was the warmest since instrumental measurement began in 1850, and the ten warmest years since 1850 have now all occurred since 1998.
If it can, we have not seen them developing as of yet. The number of hurricanes has risen slightly, but the strength and intensity has been shown to have decreased over the past several decades.
Part of the theory of global warming is that greenhouse gases capture the earth's heat. If more greenhouse gases are added to the atmosphere then more heat will be retained.We can measure that levels of greenhouse gases have increased, and we can measure that temperatures have risen. These measurements thus support the theory of global warming.
The earth's average global temperature has risen 0.75 degrees Celsius (approx 1.3oF) in the last hundred years.A:The earth has warmed by 0.9 degrees Fahrenheit in the past 100 years. A:0.82 degrees Celsius.Approximately 0.6 degree Celsius.
Yes. The application of scientific knowledge has proven that global warming is real and has established that it is, amongst other factors, the result of human activities such as burning fossil fuels (coal, oil and natural gas).
Earth is a ball shape and the light shine on earth hit earth. While earth is a ball of surface area 4.pi.R2 but earth is visible to sun as a circle with area Pi.R2. Visible area to Sun V.S. actual surface area is the key to different light intensity. Picture the equator, light is most intense at the centre (most intense/area). At North or South pole, light is less intense since it is more surface area than visible area. So it was not heat-up evenly and so the temperature variation. There are many more factor such as wind direction, geometry shape of terrain and water current add extra variation to global temperature as well.
There have been changes in temperature in the past, but climate scientists say that average global temperatures have never risen as quickly as they are now.
Global warming is a rapid change. The earth's temperature has risen very fast in the past 50 years, compared to the very gradual rise over the past 12,000 years, the time of the last Ice Age.
In recent decades, the average temperature rates in the world have risen.

A few suggestions to answer your question:Search for the meaning of the greenhouse effect. Make sure you understand the natural effect, and the enhanced greenhouse effect.Find out how much the temperature has risen since global warming began at the start of the Industrial Revolution.Find possible solutions to the greenhouse effect, by governments and by individuals
Considering that the warmer temperature is melting the permafrost and releasing huge amounts of methane, the change in sea temperature is changing the climate patterns causing drought, the ocean levels have risen it may well be too late. The best we can hope for is to adjust to a new "normal" that isn't too hard on our species.

It has risen o.74 of a degree due to global warming in the last century. Almost all of this before 1934. From 1935 until present we have seen about 0.2 degrees of additional warming. The averages though appear to be trending upwards, although there is debate on several issues regarding the accuracy of various methods when dealing with such small increases.

Within the last 100 years there has been a 1 degree Fahrenheit temperature increase in the United States. The warming is uneven. Alaska has warmed about 5 degrees since 1960.Sea levels have risen globally by 1.8 mm per year for the last 100 years.

1886 was when the first fully working gas-powered vehicle was invented. I know this because I had to debate that global warming is caused mostly by human acivity in school. I used it as evidence, since when it was invented the annual temperature has slowly risen.
