Hi There,
SideWynder:
...y'all should know by now that the SUN has absolutely no influence on the Earth whatsoever at all!!!
What an incredibly daft statement! I had to read this poster's post twice to discern if it contained any credibility at all behind its incomparable
ignorance. Earth's climate is directly linked to the suns's output. The earth's positional orbit and distance from the sun is equally a criterion
of immense importance, especially for all life forms.
Think of it this way. The closer one gets to a blazing coal fire, the warmer one is, the further away, the colder one is. The hotter the coal fire
burns the warmer the climate in the room, and should the fire become small or even go out, the room goes cold. It's that simple.
With the sun, the interconnecting variables that affect each other are somewhat more complicated than a coal fire. Radiation from the sun which the
earth receives drives many of the earths climate mechanisms. Indications are that the earth may experience a temporary lessening in solar output, and
it is the length of 'temporary' that bears an important value to earth's climate.
Adjustments may be small, but the scale on which they will happen will make the effects seem amplified. A degree or two less in solar output, could on
a planet's scale, mechanize a mini ice-age. Equally, atmospheric effects may cause detrimental effects for life on earth.
Earth's ability to host life in all its diversity is based on a consistent stability within a narrow band of interconnected variables. If one or more
of those variables should weaken or disappear, that 'hole' has to be filled by some other mechanism; such an adjustment may not be beneficial to
many life forms, including ourselves. However, we are quite an adaptable organism, so as long as we are able to maintain minimal environmental
requirements for life to continue, we should survive.
The earth's climate has (and is) changing, and it isn't simply down to man's output of waste products. In fact, I would say rather than man causing
climate change to occur...he hasn't, but he has contributed to it on a effective scale over many years since the beginning of the industrial
revolution some 300 years ago. His contribution has been small, but significant enough to accumulate incrementally over the years to eventually help
tip the scales of stability with other natural processes by which climate mechanisms operate. Any lessening in solar output upon the earth holds a far
greater significance and impact. When we speak of climate change (which is a daily reality) we have to factor in many of the variables that contribute
to the change...those that weaken or disappear, and those that take their place.
The most significant aspect of climate change, however, is the scale and the speed at which it occurs. Changes occurring over a few weeks are far more
damaging than those that take years to do so, because it does not allow us time to prepare or adapt quickly enough. These are the immediate concerns
we should be looking at regarding climate change...the longer term issues can be tackled accordingly (that is to say, if we are able to tackle the
concern at the scale at which it is occurring?).
