The relationship between air cleanliness and global warming is one that is quite easy to make sense of. One does, however, need to take note of the fact that this is a controversial relationship: as there are, indeed, folks who are not yet convinced that the whole global warming paradigm is truthful.
Ultimately, the relationship between air cleanliness and global warming is one where it is argued that interference with air cleanliness (through carbon emissions) is what leads to global warming. Thus, it is postulated that folks who want to stop global warming have to do something to reduce carbon emissions. Conversely, it is opined that if the carbon emissions, which mess up with air cleanliness, continue going up a point will come when very harmful manifestations of global warming will start being witnessed.
Most of the people who subscribe to that view tend to express interest in recruiting campaigners, to spread the message around. In most cases, you just need something as simple as a free Gmail account set up at the www.gmail.com site, to sign up as a campaigner for reduction of carbon emissions and global warming. Most campaign groups also welcome financial assistance, and other forms of help, to people who are ready to spread their message.
