Why might an increase in atmospheric CO2 result in an increase in global temperatures?

This is so because CO2 is a green house gas which does not allow the harmful UV rays of the sun trapped by the Earth to go back , which increases the temperature of the Earth.
So if carbon dioxide will increase , surely the temperature would also increase.

Can Greenhouse gases change Earth's average surface temperature?
Yes. They can and they do. Any increase in the level of carbon dioxide or methane in the atmosphere will result in an increase in average global temperatures. This typically results in evaporation of additional water vapour, creating a slight amplifier effect, to further increase surface temperatures.
What could happen if you let globle warmig happen?
Global warming simply means an increase in atmospheric temperature on a global level. One significant effect effect of this temperature rise is the melting of our polar ice caps, which will eventually result in a rise in sea level.
Why did the mount Pinatubo eruption result in global temperatures dropping almost two degrees?
The 1991 eruption of Mount Pinatubo released massive quantities of sulfur dioxide. This led to the formation of tiny droplets of sulfuric acid in the stratosphere. These reflected sunlight back into space, reducing global temperatures.
What you mean by climate change?
Climate change is often used interchangeably with the term 'global warming', although it includes predicted changes that are the result of global warming. Global warming is a term used for the gradual increase in average global temperatures since the beginning of the Industrial Age, and is considered to result from human activities such as burning fossil fuels (coal, oil and natural gas) and deforestation. Climate change includes global warming, of 0.75 degrees Celsius since 1850, when instrumental measurements began, and predcitions of a further 2 or more degrees over the present century. It also includes sea level rises, more prolonged droughts, more frequents severe floods and more intense storm activity, all influenced by increased average global temperatures. Climate change will bring fundamental changes to the environment in which we live.
Which of the phenomena is supposedly associated with globol warming?
One of the phenomena supposedly associated with global warming is the rise in average global temperatures. As greenhouse gases such as carbon dioxide accumulate in the atmosphere, they trap heat and lead to an increase in the Earth's overall temperature. This can result in various consequences, such as melting ice caps, rising sea levels, and more frequent and severe heatwaves.
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 is global freezing?
Global freezing is the process by which the temperatures across the planet drop to the power where surface water begins to freeze. This is commonly associated with an Ice Age but can also result from extreme atmospheric changes.
Is Antarctica the cause of global warming?
Following the definition "an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the enhanced greenhouse effect.". It is safe to assume that Antarctica is not causing global warming.
How will an increase in carbon dioxide most likely affect earth?
Carbon dioxide is a greenhouse gas that in normal concentrations helps keep the earth at a comfortable temperature, suitable for human existence. Scientists tell us that the increase in the atmospheric concentration of carbon dioxide since pre-industrial times has been accompanied by a gradual increase in average global temperatures. They warn that the rate of increase is rising rapidly and will result in extreme global warming and climate change unless we reduce our carbon dioxide emissions.
Can Greenhouse gases change Earth's average surface temperature?
Yes. They can and they do. Any increase in the level of carbon dioxide or methane in the atmosphere will result in an increase in average global temperatures. This typically results in evaporation of additional water vapour, creating a slight amplifier effect, to further increase surface temperatures.
What is the result of increasing the temperatures of a gas?
The kinetic energy will increase
What do CO2 and atmospheric CO2 levels and the global temperature from the last 150 years have in common?
They're both increasing, in pretty good correlation with each other. Most of the increase in carbon dioxide is a result of human activities. Additionally, and similarly, much of the observed increase in temperature is a result of humans.
Does a change in natural levels of greenhouse gases warm the earth?
Greenhouse gases include carbon dioxide and methane. A reduction in the amount of these gases in the atmosphere would result in global cooling, while an increase results in higher global average temperatures - global warming.
What could happen if you let globle warmig happen?
Global warming simply means an increase in atmospheric temperature on a global level. One significant effect effect of this temperature rise is the melting of our polar ice caps, which will eventually result in a rise in sea level.
How might global warming affect the clouds?
Clouds are one of the big unknowns about global warming as they can have a range of effects, warmer temperatures caused by global warming will result in higher rates of evaporation and therefore will result in higher cloud cover. in turn higher cloud cover can increase night time temperatures by acting as insulation and preventing heat escaping the atmosphere during the night. At the same time clouds can reflect sunlight resulting in reduced daytime temperatures. the local impact of clouds will depend on the humidity of an area.
When will the effects of global warming really affect us?
Global warming began affecting us with record warm temperatures and retreating glaciers in the 1980s. Although we cannot point to any specific storm as a result of global warming, overall the violence and intensity of storms (though not necessarily their frequency) is expected to increase. Warmer oceans will provide more energy for hurricanes. Hotter temperatures will also increase desertification in many areas. Much of the central and western US is currently suffering from a prolonged drought, largely the result of anthropogenic global warming.
Why do some scientists theorize that global warming not be the result of increases in atmospheric carbon dioxide?
Many scientists hypothesize that deforestation intensifies global warming trends.
