Global temperatures have been increasing over the past couple of decades, but there has been no evidence demonstrated that this warming is unusual, long term or detrimental. Most of the more alarmist research is based on computer generated models which can be discredited on the data they choose or the methodology without any deeper look into their conclusions; this is similar (in an odd way) to the sub-prime housing crisis, where all the risk management models failed to accuately determine the risk because of bad data fed into them.
"Global Warming" has become the cause of radical socialist groups in an effort to gain political power and (for the most part) they use "Global Warming" as a blanket cause to push forward political ideals that have (historically) been in opposition to the societies that they live in. They're very agressive in their attempts to marginalize anyone who disagrees with them because their underlying values require consensus before action can be taken; if you spend time around what I would term "neo-Environmentalists" you will see how heavily they talk about "tollerance" while at the same time stereotyping, scapegoating, and preaching hate about any group that disagrees with them.
What should be done is simple, the over use of energy resources is a massive global problem for environmental (there are tons of issues besides "global warming"), geo-political, ecconomic and sustainable development reasons. Most of the energy we use is unnecessary and can (easily) be scaled back using modern and emerging technologies. Governments should stop "helping" people by offering rebates on their energy bills because it discourages people from becoming more efficient.
