The event of Global warming is the increase of the average temperature of both the atmosphere and the oceans of Earth. Global warming is most commonly accredited to the greenhouse effect.
Methods for Finding the Temperature
One method used to find the temperature of the earths atmosphere and ocean is the use of satellites to find the radiances in numerous wavelength bands that will thus allow one to deduce the temperature of the area studied. The results of this method have shown that the average temperatures of the earth have been on a rather steady climb over the past 20 or so years. This time period is so small because the technology needed to measure in this way was only just invented recently. The results also show that the temperature is being affected by CO2.
Another method used to determine the presence of global warming is the examination of atmospheric samples found inside ice cores. The levels of CO2 found in these ice cores compared to the levels in the air today are significantly different as can be seen from the graph below.
Links between Atmospheric CO2 and Global Warming
A link between atmospheric CO2 and global warming is that they are both increasing, with the amount of CO2 in the atmosphere rising and the earths average temperature rising alongside it. These two aspects have both been moving at substantial rates but really there is not much strong evidence, if any of them being directly linked to one another. Everything is mainly speculation.
Predictions about Effects of Global Warming
It has been predicted by IPCC (International Panel for Climate Change) that if global warming is to continue at its current rate then we are facing a possible rise of temperature from 1.1°C to 6.4°C by 2100. Along with this, if one were to acknowledge the possibility of certain points where the speed of the rise in temperature were to accelerate the temperature could rise up to anywhere between +8°C or +11°C. This would make living...
