More research needed on climate change and global warming

I was reading an Associated Press article by Beth Duff-Brown entitled "Warming experts stick their heads in the clouds - Water droplets found where ice crystals should be above Canada's Arctic" about some ongoing research into an unexpected phenomenon of super-cooled water droplets rather than solid ice crystals in Arctic clouds and how it may tie in with global warming. In particular, the article says that scientists are uncertain whether this phenomenon is a cause or an effect of global warming.

What???

From all that I read in the press lately, climate change and global warming are now beyond debate and the causes and expected effects are supposedly well known. Now, we hear that some serious scientists are either simply unsure of some of the effects, or actually unsure about some of the causes.

If more research is needed, I'm all for it. And if there is any uncertainty about any of the effects, let alone any of the causes, of global warming, by all means we should dramatically ramp up the research, and do so before proceeding to set environmental policy and economic and industrial policy. The very last thing in the world that we want to do is pursue changes to environmental policy that could well be far more calamatous for the environment than the evolving state of current policies.

We need to get a lot closer to a truly deep understanding of the causes and effects and implications of global warming and climate change. It is far too soon to pursue policy changes as a knee-jerk reaction to over-zealous activists.
