Does CO2 always correlate with temperature (and if not, why not?)
Jan 20, As carbon dioxide levels in the atmosphere increase global warming increases, assuming no other changes. As carbon dioxide has changed in the past, many other aspects of climate Global Warming Home > Temperature Change and Carbon Dioxide Change due to the relationship between temperature and the solubility of carbon dioxide in the. Jun 11, Scientists have found a direct relationship between carbon dioxide emissions and global warming. Researchers used a combination of global.

Radiative forcing units are expressed as the power watts per square meter surface area of Earth. This literally means that the heat-trapping emissions we release today from our cars and power plants are setting the climate our children and grandchildren will inherit.

What about water vapor? Water vapor is the most abundant heat-trapping gas, but rarely discussed when considering human-induced climate change. The principal reason is that water vapor has a short cycle in the atmosphere 10 days on average before it is incorporated into weather events and falls to Earth, so it cannot build up in the atmosphere in the same way as carbon dioxide does. The higher temperature atmosphere can then hold more water vapor than before.
Why does CO2 get most of the attention when there are so many other heat-trapping gases?
Too much of a good thing: The numbers represent the amount of energy associated with each source in watts per square meter. The numbers in parentheses represent the range of uncertainty surrounding the measurements.
Long-wave radiation absorbed by these gases in turn is re-emitted in all directions, including back toward Earth, and some of this re-emitted energy is absorbed again by these gases and re-emitted in all directions.
The net effect is that most of the outgoing radiation is kept within the atmosphere instead of escaping into space. Heat-trapping gases, in balanced proportions, act like a blanket surrounding Earth, keeping temperatures within a range that enables life to thrive on a planet with liquid water.
Based on an average carbon footprint, you can test ways to mitigate global warming yourself.
Alternatively, you can have a look at some simulation results how global warming can be stopped below 2 C. Have a look at the CO2 emissions per capita by country to see how far away from this goal value of 2 tons per year our western life style is.
In a fair world, there is absolutely no justification for the western world to pollute the Earth more than others. So we should aim to reduce our carbon footprint to 2 tons per capita per year until The above mentioned goal can only be reached if our life style becomes a sustainable one.
The first and most efficient measure is a reduction of our energy consumption. In addition, it is inevitable to make thoughts about the true meaning of life and change our personal behaviour accordingly. There are several reasons why.'Relationship between CO2 and global warming hardly measurable'
Doubling the amount of CO2 does not double the greenhouse effect. The way the climate reacts is also complex, and it is difficult to separate the effects of natural changes from man-made ones over short periods of time.
As the amount of man-made CO2 goes up, temperatures do not rise at the same rate. So far, the average global temperature has gone up by about 0. Two-thirds of the warming has occurred sinceat a rate of roughly 0. Unfortunately, as this quote from NASA demonstrates, anthropogenic climate change is happening very quickly compared to changes that occurred in the past text emboldened for emphasis: In the past century alone, the temperature has climbed 0.
