We all gather in this guild for one purpous.
To save what we are destroying.
Global Warming is becoming a big thing. And we are here to help control it.

What Global Warming is! taken from fightglobalwarming.com
The atmosphere has a natural supply of "greenhouse gases." They capture heat and keep the surface of the Earth warm enough for us to live on. Without the greenhouse effect, the planet would be an uninhabitable, frozen wasteland.
Before the Industrial Revolution, the amount of carbon dioxide (CO2) and other greenhouse gases released into the atmosphere was in a rough balance with what could be stored on Earth. Through photosynthesis, for example, plants take in carbon dioxide while the process of respiration or metabolism releases CO2 back into the atmosphere.
New conveniences too much of a good thing
Industry took off in the mid-1700s, and people started emitting large amounts of greenhouse gases. The fossil fuels we burn to run our cars, trucks, factories, planes and power plants add to the natural supply of greenhouse gases. The gases—which can stay in the atmosphere for at least fifty years—are building up beyond the Earth's capacity to remove the gases and, in effect, creating an extra-thick heat blanket around the Earth.
The result is that the globe has heated up by about one degree Fahrenheit over the past century—and it has heated up more intensely over the past two decades.
If one degree doesn't sound like a lot, consider this: the difference in global average temperatures between modern times and the last ice age—when much of Canada and the northern U.S. were covered with thick ice sheets—was only about 9 degrees Fahrenheit. So in fact one degree is very significant—especially since the unnatural warming will continue as long as we keep putting extra greenhouse gases in the atmosphere.
How much is too much?
Already, people have increased the amount of CO2, a key greenhouse gas, in the atmosphere to 31 percent above pre-industrial levels. There is more CO2 in the atmosphere now than at any time in the last 650,000 years. Studies of the Earth’s climate history show that even small changes in CO2 levels generally have come with significant shifts in the global average temperature.
Scientists expect that by 2100, the global average temperature will increase another 2.5 degrees Fahrenheit to 10.4 degrees Fahrenheit, more than they predicted just seven years ago. A couple degrees may not sound like much, but it took only a nine-degree shift to end the last Ice Age 14,000 years ago.
Even if the temperature change is at the small end of the predictions, the changes to the climate are expected to be serious: more intense storms, more pronounced droughts, coastal areas more severely eroded by rising seas. At the high end of the predictions, the world could face abrupt, catastrophic and irreversible consequences.

The science is clear
Scientists are no longer debating the basic facts of climate change. In December 2004, Science magazine published an analysis of 928 peer-reviewed science papers on climate change from science journals between 1993 and 2003. The analysis found that not a single scientific article disputed the evidence that the climate is warming because of human activities.
Unfortunately, a similar analysis of media reports had very different findings: about half still framed the issue as a science debate.
The Science study showed the consensus among respected individual scientists. Here’s what highly respected science organizations say:
+In a joint statement with 10 other National Academies of Science, the U.S. National Academy of Sciences said:
"The scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action. It is vital that all nations identify cost-effective steps that they can take now, to contribute to substantial and long-term reduction in net global greenhouse gas emissions."—Joint Statement of Science Academies: Global Response to Climate Change, 2005
+The American Geophysical Union, a respected organization comprising over 41,000 Earth and space scientists, wrote in its position on climate change that "natural influences cannot explain the rapid increase in global near-surface temperatures observed during the second half of the 20th century."

The increaces in the global's average tempature.
all I gotta say is thats a huge raise!
