Don't worry. Nuclear winter will cancel out global warming.
It sounds to me as if they are hedging their bets.
Is it possible that they realize a natural ebb and flow of climate and temperatures can`t be blamed forever on humans(Americans specifically).
Maybe they figure that after a while with reduced emissions,hybrid cars,etc people will start to ask why the issue of global warming does`nt go away.
By the way I never hear about the hole in the ozone over Antarctica anymore.I think I heard that "the hole" had somewhat reduced in size.Please someone correct me if I am wrong as to this.
Create greenhouse gasses????? It will produce trees. Is the conversion of CO2 to Oxygen really going to end the world????
Too many ice cubes in my bourbon?
Obviously it was NOT human activity that caused it to be warm 11,001 years ago when it was last melted. The fallacy of their argument is in their own facts!
Fascinating. If permafrost can't come back, then how was it orignially created???? Obviously these people are closet creationists.
The squirrels have started harvesting spruce cones as of today. They do this every year, and sure enough, winter has followed every time. Can the squirrels not know of our impending doom?
I bet if we killed every cow in the world we could offset this problem!
I thought Antarctica was.
It can, but it takes at least one cold summer. It also depends on snow cover. If there is no snow cover the cold can get very deep into the soil. Permafrost right here starts near the surface and goes down 20 feet. In some places it is 200 feet deep. The freezing/thawing cycle on naturally vegetated land mainly hits the top couple of feet.
It's his fault, of course!
What will happen to world turnip consumption now!!!
Well, maunder means to talk inchoherently or to move aimlessly, something I've been known to do by the time my ice cubes melt in my bourbon. The explanation you're looking for is below however and I didn't use google Wiipedia is better! ;^)
The Maunder Minimum is the name given to the period roughly from 1645 to 1715 A.D., when sunspots became exceedingly rare, as noted by solar observers of the time. It is named after the later solar astronomer E.W. Maunder who discovered the dearth of sunspots during that period by studying records from those years. During one 30-year period within the Maunder Minimum, for example, astronomers observed only about 50 sunspots, as opposed to a more typical 40,000–50,000 spots.
Sunspot observations
The Maunder Minimum occurred between 1645 and 1715 when only about 50 spots appeared as opposed to the typical 40–50,000 spots. The minima counts for 10-year periods from 1610-1681 are as follows:
Decade Sunspots
1610 9
1620 6
1630 9
1640 2
1650 3
1660 1
1670 0
1680 1
During the Maunder Minimum enough sunspots were sighted so that 11-year cycles could be extrapolated from the count. The maxima occurred in 1674, 1684, 1695, 1705 and 1716.
The sunspot activity was then concentrated in the southern hemisphere of the Sun, except for the last cycle when the sunspots appeared in the northern hemisphere too.
According to Spörer's law, at the start of a cycle spots appear at ever lower latitudes, until they average at about lat. 15° at solar maximum. The average then continues to drift lower to about 7° and after that, while spots of the old cycle fade, new cycle spots start appearing again at high latitudes.
The visibility of these spots is also affected by the velocity of the sun's rotation at various latitudes:
Solar
latitude Rotation period
(days)
0° 24.7
35° 26.7
40° 28.0
75° 33.0
Visibility is somewhat affected by observations being done from the ecliptic. The ecliptic is inclined 7° from the plane of the Sun's equator (latitude 0°).
Little Ice Age
The Maunder Minimum coincided with the middle — and coldest part — of the so-called Little Ice Age, during which Europe and North America, and perhaps much of the rest of the world, were subjected to bitterly cold winters.
Whether there is a causal connection between low sunspot activity and cold winters is the subject of ongoing debate. Some scientists believe that solar variation drives climate change more than carbon dioxide does (see global warming).
Other observations
Recently published research suggests that the Sun's rotation slowed in the deep Maunder minimum (1666–1700).[1] (#wp-endnote_Vaquero2002) At our current level of understanding of solar physics, a larger and slower Sun necessarily implies a cooler Sun that provides less heat to Earth. (The mechanism behind the Sun's expansion and contraction is still unclear, although many stars undergo pulsations to some degree or another; see variable star.)
Solar activity events recorded in radiocarbon.The lower solar activity during the Maunder Minimum also affected the amount of cosmic radiation reaching the Earth. The resulting change in the production of carbon-14 during that period caused an inaccuracy in radiocarbon dating until this effect was discovered.
Graph showing proxies of solar activity, including changes in sunspot number and cosmogenic isotope production.Solar activity also affects the production of beryllium-10, and variations in that cosmogenic isotope are studied as a proxy for solar activity.
Other historical sunspot minima have been detected either directly or by the analysis of carbon-14 in ice cores or tree rings; these include the Sporer Minimum (1450–1540), and less markedly the Dalton Minimum (1790–1820). In total there seem to have been 18 periods of sunspot minima in the last 8,000 years, and studies indicate that the sun currently spends up to a quarter of its time in these minima.

How long have you lived there?
This must be true in order fro it to have organic material there in the first place.
Everytime you check the actual temperature records for an area subject to "global warming" like this, you find the story was full of sh__.
Somebody look up the historical temperature records for Siberia. You'll find it's up and down and no real trend can be ascertained.
