I often find it interesting that news reports and scientific investigations into AGW so often provide proof that, as Battlestar Galactica fans will realize, this has all happened before and will happen again
Scientists are to dig up ice dating back more than 100,000 years in an attempt to shed light on how global warming will change the world over the next century.
The ice, at the bottom of the Greenland ice sheet, was laid down at a time when temperatures were 3C (5.4F) to 5C warmer than they are today.
The story goes on to say that scientists, after consulting Madame Zelda, reading some tea leaves, and casting some chicken bones, have decided to go with the shocking figure of an up to 7C change (no hedging bets, eh?)Â in the next 100 years (when we’ll all be dead anyhow.) Quite frankly, I’m more worried about the massive debt and socialism/nationalism that our descendants will be left with, which is one heck of a lot more man made then global warming, which, come to think of it, is causing it to get cold. Let’s go to some scientific charts not based on computer models and overblown hyperbole
Via those Evil Deniers at Powerline, from the naughty skeptics forum in early March.
Teach do you have any “descendants” ? How does this effect your views global climate change ?Temps have changed and will continue to do so. However, I think that we would both agree that life as we know it for plants and animals would be better without any drastic changes. Can man have an effect on his environment ? Can the environment change climate ? 10,000 years ago the world population was 1 million, now the world population is 7,000 millions could this have an effect on the climate ?Could one say that since the world population has increased that we have not had a serious and prolonged ice age but only very minor short lived ones ?
ANd could you explain why in the left hand side of the 2 graphs both the x and y axis is marked in what appears to be years ?
John, global warming is primarily natural. As I have said before, many times, Man does play a small part, particularly with the world populations. But, I think you are reading way too much into the population. There is almost no correlation between CO2 and temps. The Earth is going to do what it wants.
well then we both agree that man does impact climate, we only disagree on to what degree. Now about those graphs, it has been a while since I took analytical geometry but I can not understand the left most graph on the second row. How can you have both the x and y axis apparently showing years? The vertical axis is markedftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_IRRADIANCE/COMPOSITE.v2.PDF Also since the population explosion from 1 million to 7.000 million why have we not had any LARGE periods of global cooling like the one we had 10,000 years ago ? Oh and by the way do you remember the posts you had about the extraordinary cold winter ?? freezing oranges in Florida etc? Jan and Feb are ranked 7th and 9th warmest out of the past 120+ years on record
