Well it is from 1996 so it is 13 years out of date.
Back in 1975 the scientists were saying we were going into another ice age, and the White House backed them.
At that time, the global temp had been cooling for several decades. (or so the scientists said)
You are a few years older than me, surely you must remember it.
You say that a report from 1996 is 13 years out of date, yet the base data has not changed in that time.
And, as well, do the scientists of present day show data that would confirm a general cooling of the planet between ~1940 and 1975?
Around +-1C variance in the last couple hundred years, and everyone cries either 'we are going to freeze to death' or 'we are going to fry and drown to death'.
Sure, our industries and usages produce CO2 - as well as many more (and more) dangerous substances. CO2 is not one of them (the dangerous substances), since it is in the cycle of Life on this planet. The more CO2, the healthier the plant life, which then absorbs the CO2 and produces O2 which we breath in to sustain our own life.
Do we need to clean things up? Yes!
Let's get rid of Mercury in our products, for a start. So, let's ban CFL's and stick with the original, tried and true, fluorescents. We can deal with a little more heat better than we can deal with heavy-metal poisoning.
As for all this 'Global Warming/Climate Change' crap, well, the climate and global temps are always changing due to natural forces (and yes, some due to our own doing, no doubt). But I really think that what we do on a planetary scale is so much less than what nature does on a universal scale that it is near to insignificant.
Haven't you even wondered why the term 'Global Warming' was changed to "Climate Change'?
It's because they can not prove something, and the term no longer applies.
The climate is changing, perhaps even drastically. But, our response should not be to try to change the changing conditions - it should be to adapt to them.
After all, isn't that what evolution is all about? The fittest adapt to changing conditions... and so become all the more stronger.
Trying to control nature through technology for our own comfort? That just reveals our own weaknesses - the concept of which, I'm sure, could begin another heated debate.
The point I am trying to make is this:
We are small in the Universal order. There have been drastic (and sometimes sudden) climate changes in the past that have nothing to do with technology. They simply happened - either for known or unknown reasons. A climate change because of a comet/meteor strike is a known factor - to a certain degree. Volcano eruptions... again a known. How about something outside of that? Like simply flying through the galaxy and universe on our own course, that brings us into an area that has enough dust to reduce the sunlight that reaches our planet and thus causes a global cooling, or an absence thereof that causes the reverse?
There is no 'normal' temperature for our planet. It is always changing, due to more factors than we can factor in with any certainty.
