Do people ever ask themselves why it is that the country which is the worlds biggest polluter is also the country that is the most resistant to the idea of climate change? Is it a coincidence? Are people so wedded to an extravagant materialist lifestyle that they just don’t want to give up consumer goods they don’t really need?

Or is it just that America is right and everyone else in the world is wrong.
US has signed a very powerful treaty with China, India, South Korea, Japan and Australia(they haven´t signed too, the protocol of Kyoto) with the equation more realistic and good, more technology, less pollution, not like the european bureaucrats wanted destroying our industry and destroying works. But the welfare state is infinite for them.
 
  1. Collect some really reliable data on hurricane volume and intensity by year for the past hundred years.
  2. Plot the volume and intensity data on a graph by year. *
  3. Visit www.sidc.oma.be and collect data on the solar cycle - plot the data by year for 100 years. [Each solar cycle is on average 11 years - it’s a rough approximation as there is great variability on cycle length. Also make sure you have the 22-year cycle data, as well.]
  4. Compare the volume/intensity graph with the solar cycle graph and see what kinds of correlations show up. Keep in mind that correlation does not prove causation.
Any discussion of a scientific topic without reams and reams of good data is no more worthwhile than a discussion in a bar room. Certainly a lot less fun.

Back in the 1970s, there was a neo-Malthusian theory peddled by a loose group of very misguided, economic illiterates that we were slowly destroying the earth and making things worse for everyone. There were conclusions by the Club of Rome that turned out to be totally absurd. If we didn’t die in the mass starvation, we weren’t going to have any energy to heat our homes during the premature Ice Age caused by sunlight-blocking pollution. None of that happened.

Typhoons have always blasted Asia and hurricanes will always blast the Gulf. We will always reach new highs and new lows. These have nothing to do with global warming. Global warming is projected to add between 0.5 and 6 degrees in the next 100 years. Since the “magic” year of Kyoto is 1990, that means that, if true, we have added between .075 and 0.9 degrees since then, of which the US may be responsible for between .01875 and .225. The earth warmed up 0.8 degrees between 1880 and 1940. Then it cooled and then it warmed. Lassen shows that temperature changes correlate perfectly with CHANGES in the length of the solar cycle. Are there drastically more and stronger hurricanes now than in 1940, and more in 1940 than 1880? I doubt it. I have seen some hurricane data and even THAT data is contested. Errors in the data have been challenged. The two recent storms caused fewer deaths than the storm that hit Galveston in 1900. There is more snow falling in the Antarctic, not less. When some people say they are talking about extremes, that’s because a lot of other misguided people are only paying attention to extremes. Confirmation bias, it’s called. And then they demand fixes, no matter whether the fix is going to cost more now than the response will later.*

Because ignorance and anti-intellectualism have been turned into attributes. If you recognize that there’s a problem, then you have to DO something about it. Ergo, people don’t recognize the problem.
Do you think accusing the Bush Administration of ignorance and anti-intellectualism is less offensive than accusing we who support Bush Administration of ignorance and anti-intellectualism?
 
Don’t accuse anyone of ignorance. Please look at the posting guidelines for assistance.

Yes every country will have to be included at some point. But if you wait for the perfect agreement before you do anything then you are just making an excuse for doing nothing. People who said lets ignore the international community and invade Iraq are saying we cannot ignore the international community and do something to tackle climate change.
How hard would it have been to say Kyoto should apply to every country? Its not rocket science to understand that the US will (hopefully) never approve a poorly thought out treaty that will put jobs at risk and give a competitive advantage to the fastest growing economy on the planet. If it applied to all countries then the odds of the US signing on would be a lot higher.

No one is talking about waiting for the “perfect” treaty, but is wanting a “fair” treaty too much to ask?

I think I heard last week that the ice in the Antartic is increasing.
I heard the same thing but can’t remember what talk show had the topic on.

This is most certainly not the case. The antarctic is one of the dryest places on the planet, receiving less precipitation than most of the great deserts of the world. The antarctic ice cap would most likely decrease even without the mechanisims of global warming simply because its present climate is a net loss of water.

Being a scientist, I tend not to listen to politicians when it comes to issues of science. To my knowledge, no peer reviewed publications refuting global warming exist. Some may take this information and use it for a public agenda, but the fact that human activity is affecting global temperatures is difficult to deny.

Imagine a billion barrels of gasoline, open at the top. Burn the gasoline. Now. you think that will be hot??? Now, how many billions of barrels of gasoline does the world burn a year???

I would like to see some studies referenced if anyone has any. I really don’t know what is happening down there.

It looks like the British had to put one of their Antartic bases on skis because all the other bases have been covered with snow. For the past few years the snow has been accumulatationg at 5 feet a year.

news.bbc.co.uk/2/hi/science/nature/4693409.stm
The Antarctic is on the OPPOSITE pole of the earth. Could it be that THE EARTH IS MORE TILTED THAN BEFORE??? Causing the Arctic Pole to be more sunny and the Antarctic Pole to be more shadowy??? Also, in combination with this, be sure to take into account the fact that the earth’s rotation around the sun is an ellipse. For example, if the Arctic is tilted towards the sun in the summer when the earth is near the sun, a more tilted earth would cause the Arctic to receive more radiation and heat from the sun, and then when winter comes, and the earth is far from the sun in its orbit, a more shadowy Arctic will cause it to be much colder than in prior years. THE SUMATRA QUAKE THIS PAST CHRISTMAS MAY HAVE TILTED THE EARTH A LITTLE BIT. WHAT DO YOU THINK?

Well. if snow is now falling there at 5 ft per year, then it means it is no longer dry. Maybe the air currents have changed or more moisture carrying clouds over the Antarctic.
 
By the way, I read in an article in a sciemce magazine in the 1970’s that THE NORTH POLE HAS A LONG TAIL, I THINK 2x or 3x the diameter of the earth.

This North Pole Tail cannot be seen by the human eye BUT BIRDS, INSECTS, AND SCIENTIFIC INSTRUMENTS CAN SEE IT. Actually the article was theorizing that maybe birds are using this northpole tail as a compass while migrating across thousands of miles and several time zones. The earth, however, has NO TAIL AT THE SOUTH POLE, BUT ONLY IN THE NORTHPOLE.

So, are you saying Dr. Lindzen is a nut-job? I always thought MIT hired really, really smart people…

How is Antarctica doing?
Well back in 2003 the Guardian reported this :

guardian.co.uk/antarctic/story/0,13993,1085643,00.html

Australian scientists yesterday revealed new evidence of global warming, suggesting that sea ice around Antarctica had shrunk 20% in the past 50 years. The research published in the journal Science traced the pattern of sea ice in the Southern Ocean as far back as 1840. “Between 1841 and 1950 there was very little change but there is a marked decline in sea ice distribution since 1950 of around 20%,” said the lead author, Mark Curran.
Code:
                       In winter, pack ice covers an area of more than 7 million square miles around Antarctica, shrinking to 1.5 million square miles during the southern hemisphere summer. At its greatest extent, the ice field is bigger than Russia.  Several studies in recent years have shown that sea ice around Antarctica has increased since the 1970s, but Dr Curran said that the short timescale of those studies failed to take longer-term trends into account. "Until now, records have relied to a large degree on satellite observations since the 1970s. Thirty years is a very short time over which to draw any conclusions," he said. A Nasa satellite study released last week showed that the growth of pack ice since the end of the 1970s was preceded by a period of shrinkage between 1973 and 1978. The break-up of the Arctic pack ice in recent years has also highlighted concerns about the implications of sea ice decline.
The evidence is taken from ice cores bored out of the Law Dome, a mound of compressed snow from the Antarctic mainland more than half a mile deep, which carries a climate record stretching back 90,000 years.

Compacted snowfall forms annual layers in the ice similar to tree rings. The scientists worked out the extent of past sea ice by measuring the amount of methane sulphonic acid (MSA), produced by marine algae, in the ice cores. MSA-producing algae is linked to sea ice, so the quantity of the chemical in any year’s snowfall gives a clue to the extent of that year’s pack ice.

I said no such thing, I’m sure Dr. Lindzen is an intelligent person and yes, MIT is a fine institution. I will say that the Cato Institute, a Libertarian think tank, is hardly capable of publishing a peer reviewed journal.

I really wish the church would take a greater involvement about this, we are always on about defending the future of the church, but If something isn’t done then there shall not be a planet Earth to practice Catholicism on in a few centuries.

**The area covered by sea ice in the Arctic has shrunk for a fourth consecutive year, according to new data released by US scientists. **They say that this month sees the lowest extent of ice cover for more than a century. The Arctic climate varies naturally

Ah yes, the ice shrinks…ok big deal. Whoever said the earth’s climate was stable? We are leaving an iceage, and before then the earth was a great deal hotter than it is now. It always seems to bounce back without too much of a problem. 😉
but the researchers conclude that human-induced global warming is at least partially responsible…“It’s the least sea ice we’ve seen in the satellite record, and continues a pattern of extreme low extents of sea ice which we’ve now seen for the last four years,” he told BBC News…
So they have been studying it for how long? Do they even have data for one solar cycle (11 year cycle)? How about more than one? For the length of man’s polution history? How can they even prove this? :confused:
The Arctic Climate Impact Assessment, a four-year study involving hundreds of scientists, projected an additional temperature rise of 4-7C by 2100.
Ah yes, when they can predict the temperatures for next year/month/week by that accuracy I might listen to their 100 year prediction. :rolleyes:

Well I for one am in support of the kyoto agreement, it infuriated me some years back at the G8 summit when President Bush refused to accpet that humans have an effect over climate control and global warming. How can America, perhaps the country that will have the greatest effect on global warming refuse to accept any responsibility? Especially with more erratic weather conditions such as Katrina and Rita occuring more frequently.
