Information About Global Warming And Climate Change
What is the real cause of global warming and climate change? Do we really know or does it need more study?
Information About Global Warming
Global warming is an obvious fact at least for the short term. Annual temperature measurements show a steady increase in temperatures around the globe.. Mean annual global temperatures have been increasing since at least the 1990s and at the present this upward trend shows no sign that it is changing.
What can be causing this? Have human activities played a significant part in the change? These two questions leave plenty of room for debate, and they are as a matter of fact the subject of a number of different of opinions. There are people on both sides of this debate who will state with utter certainty that the facts which support their case leave absolutelyno room for any debate, and that anyone who dares to disagree with their ideas is either a total fool, who is totally misinterpreting the data, or must be a charlatan who is promoting his false claims either to benefit himself or for a sponsor who has supported his studies, and who will gain a benefit from obtaining results which support his cause, either academically or finamncially.
No true scientest who is worth listening to will ever state that there is no room for further investigation and debate, and that any time that is spent doing further studies of a subject is a wasted effort. This applies no less to the subjects of climate change and resulting global warming than it does to any other scientific study. We have many so called "facts" which have been used in support of arguments on both sides of these subjects. These "facts" are often quite debatable in themselves and the conclusions which are drawn from them can certainly not be considered to be infallible.
Most of the studies which have been done cover climate change for only a few hundred to a at most a few thousand years, whereas the earth's climate has seen many profound changes over the course of hundreds of millions of years. Some areas which presently have temperate or cold climates were once tropical as plainly shown by fossil evidence. Similarly arctic climates once prevailed where now there are temperate or warm regions. Just ten thousand years ago all of Canada and the northern USA was under a blanket hundreds of feet of ice during an ice age. Climate change can,t be more extreme than that, and this was all the result natural causes long before modern man came along to play any part in climate warming.I firmly believe that human activities have played a role in global warming. The real question, which requires much more study, is how much of a part has our pollution of the atmosphere and the oceans, and our rape of the land and forests, really played in global warming. It could well be be that we are only responsible for a very tiny fraction of the observable climate changes. If that is the case then modifying our activities will have little if any noticeable effect, and the climate changes which are caused by natural conditions will continue regardless what we do. Is this how things really stand? I certainly don't know, and I don't believe that anyone else knows with any degree of certainty either no matter what they claim to believe. We really must do a lot more study of the facts.For much more informationabout the pros and cons of global warming see our website at [please contact me for website address]
