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.

∙ 13y agoThe average global temperature has risen approximately 0.8°C since the 1850s.
See the graphs at the links below. In the animation see how fast the temperature is increasing in the final few years up to the present.

Can ash cause global temperatures to rise?
ash cannot cause global temperatures to rise. At least not all the time
Which aspects of El Nino can give scientists a preview of Earth as temperatures rise with global warming?
A. Its warming of sea surface temperatures
What connection exists between global warming and human activities?
As long ago as the nineteenth century, scientists discovered that changes in the level of atmospheric carbon dioxide gases can result in corresponding changes in global average temperatures. However, they did not yet have sufficient evidence that carbon dioxide levels were beginning to increase or that global average temperatures were beginning to increase correspondingly. Since the 1970s, climate scientists have linked the rise of more than 35 per cent in atmospheric concentrations of carbon dioxide to the concurrent rapid rise in global average temperatures. They have also proven that the increase in carbon dioxide levels are caused by human activities. So, joining the dots, global warming is caused by human activities.
What effect is a phenomenon in which carbon dioxide and other gases trap solar radiation in the atmosphere causing global air temperatures to rise?
Carbon dioxide and other "greenhouse" gases are trapped in the atmosphere due to a phenomenon referred to as global warming. Global warming refers to the constant and steady rise of the Earth's temperature.
Is the current rise in global temperatures natural or human explain the answer?
Rising global temperatures have also been accompanied by other changes ... Are human activities or natural variations in climate responsible for the ... warming we have seen in the past 50 years cannot be explained by natural factors alone.
What is a word that means a rise in average global temperatures?
Global Warming
Can ash cause global temperatures to rise?
ash cannot cause global temperatures to rise. At least not all the time
A rise in average global temperature?
Global warming
2 exemple the global warming?
Global warming examples include rising temperatures, rising ocean levels, and decreases in global land and sea ... A global average temperature rise of 2 degrees Celsius or less in coming years.
What term is characterized by a rise in temperatures and a change in climate patterns?
Global warming

What is a rise in average glob temperature?
Global warming
Why is antarctica important to aglobla warming?
Almost all of Antarctica is covered by ice, so it's greatly affected by a global rise in temperatures. When this ice melts and glaciers collapse, sea levels all over the world rise.
As temperatures rise the body temperatures of what organisms rise?
As temperatures rise, the body temperatures of heterotherms also rise. This is in contrast to homeotherms, who have a constant body temperature.
How much of global warming can be blamed on humans?
Here we are speaking of the increase in average global temperatures since the beginning of the Industrial Age. The rise in temperatures is consistent with the rise in greenhouse gas levels, which in turn is consistent with carbon dioxide emissions from human activities. However climate scientists cautiously say that human activities are "substantially" the cause of this global warming, leaving open the possibility that a much less substantial contribution could be found from natural causes. Thus the cautious answer could be that most, if not all, the recent global warming effect is due to human activities.
What are three things that can be caused by global warmng?
there can be rise in sea levels due to the melting of ice. Rising of temperatures can lead to the extinction of more than a million species. Due to the rise of temperatures in the ocean, coral reefs are begining to disappear.
