That may be the case for natural warming cycles which have occured in the past. But what scientists are primarily concerned about is man-made warming, since the data indicates it is occuring at a far faster rate than the geologically-recorded warming periods of the past.
Max. Loved the video! Here's a simple fact to debunk the global warming "scientists." I heard this from my meteorologist friend, but it was confirmed at a seminar at Stanford given by one of the "leading experts" in global warming and an adviser to Al Gore:
Historical measurements show that warming takes place BEFORE a rise in atmospheric CO2. The "scientist" claimed that it was indeed puzzling but nonetheless proved that CO2 CAUSED global warming.
I guess they now just have to work on new physics to show how an effect can precede a cause.
Max, per the polar ice sheets: If you look closely, you'll find that anytime someone mentions "decreasing ice volume", they are most often referring only to the Arctic (North Pole). Did you know that ANTarctic (South Pole) ice volume is actually increasing? I won't argue for or against Global Warming... I simply encourage people to do some reading on the "other side" of what they believe, then maybe the truth will be found somewhere in between. There are a lot of people making a living coming up with data on either side, so we would be wise to take their assertions with a bit of healthy skepticism.
Any speculation without data is just an educated guess. The data from all sources needs to be available for everybody to view. The interested parties, no matter their assigned standing in life, need to publish their scientific or other methods and conclusions. Once that starts rolling, progress can be made.
And how can we start? Simply, any one with known data should start publishing it on the internet. Various sites will emerge and various conclusions will be drawn. After time, agreement will be reached and can then be acted on.
Without a traceable map of various people's sources and efforts, no consensus will be reached by enough people to make a difference.
Good Point -- I hadn't thought about that. Also I read somewhere that the warming effects in some layers of the atmosphere were being offset by some other effects in other layers of the atmosphere, but that these other effects wouldn't last...
You wrote: " and they were having the worst snow for years and years … "
Increasing snowfall is not an indicator of colder weather as much as it's an indicator of increased moisture content in the atmosphere. This is something predicted consistently since over 15 years ago, that global warming would lead to increased moisture content and more water in storms in all seasons.
