This site is a reference point for those with a cool head for climate science, arguably the most political science ever. When the government and most of the media concentrate on alarmism, this site is the antidote for those who don't believe the scare stories - YOU ARE NOT ALONE!

WHAT CAUSES CLIMATE CHANGE?
The CO2 Coalition is a very interesting website with a large number of informative posts. Here is one of them:
Below are the 5 main reasons our climate changes. There are studies of what is the main cause of why our climate has changed. IF you decide to go to the link, you will see the studies show humans are the cause of climate change on earth. CO2 coalition only suggests what might change climate. These several studies show what did change the climate.
Solar activity also warms or cools the planet by increasing or decreasing the amount of radiation reaching the Earth's atmosphere and surface.
Volcanic activity generally cools the planet over short timeframes by releasing sulfate aerosols into the atmosphere, which block sunlight and reduce the amout of solar radiation reaching the surface. However, unlike many greenhouse gases, aerosols are washed out of the atmosphere quickly, mostly after just 1-2 years. Thus the main volcanic impact on long-term temperature changes occur when there is an extended period of particularly high or low volcanic activity.
Human aerosol emissions (primarily sulfur dioxide [SO2]) also tend to cool the planet. The main difference is that unlike volcanoes, humans are constantly pumping large quantities of aerosols in the atmosphere by burning fossil fuels and biomatter. This allows human aerosol emissions to have a long-term impact on temperatures, as long as we keep burning these fuels. However, because aerosols have a number of different effects (including directly by blocking sunlight, and indirectly by seeding clouds, which both block sunlight and increase the greenhouse effect), the magnitude of their cooling effect is one of the biggest remaining uncertainties in climate science.
The El Niño Southern Oscillation (ENSO) is an oceanic cycle which alternates between El Niño and La Niña phases. El Niño tends to shift heat from the oceans to the air, causing surface warming (but ocean cooling), whereas La Niña acts in the opposite manner. As we'll see, a few studies have begun examining whether ENSO has had a long-term impact on global surface temperatures. Because it's a cycle/oscillation, it tends to have little impact on long-term temperature changes, with the effects of La Niña cancelling out those of El Niño.
