Master ![]() ![]() ![]() ![]() ![]() | ![]() NXS - 2009-12-08 10:58 AM The CRU admitted they dumped most of the raw temp data.http://www.timesonline.co.uk/tol/news/environment/article6936328.ece That is not something that is done and their excuse is pretty lame. Another good read showing the implications of the scandle is here: http://www.telegraph.co.uk/comment/columnists/christopherbooker/6679082/Climate-change-this-is-the-worst-scientific-scandal-of-our-generation.html You and I will probably never agree on the man made global warming debate and that is OK. I just don't want to see economic disaster and the transfer of US dollars (borrowed since we are so far in the hole we have to look up to look down) to third world countries to pay for our industrial sins. It is about money, it always is, its the nature of the game those in power play. Well to say they deleted the data is a bit misleading. As I understand it they got the raw data from the met services all over the world, performed their quality control and homoginization routines and then deleted the raw data. This happened back in the '80's back before global warming really blew up so if anyone thought to falsify back then they had some pretty good foresight. It's a bit troubling for the fact that we can't go back now and verify that the quality control and homogenization procedures they used didn't have any errors. Except for one thing. The actual raw data IS still held by the various met services around the world, just not the copies of that data that they gave to CRU. So if someone wanted to go gather all that info off the magenetic tapes and whatnot from the various met services around the world and compare it the qc'd data they can go ahead and do that to see whether some nefarious sceme was hatched back in the '80s. And again, this is just one data set. There are three other major climate data sets which were independently acquired qhich are almost identical. Right now the only viable theory we have for the change in the climate is that we're causing it. If someone wants to believe that it's all a giant conspiracy and that thousands of scientists are in on faking the science (as opposed to the financial inetrests driving the RESPONSE, which I agree do exist), that the peer review process is all a sham and none of the scientific literature is valid then I guess there is not amount of evidence that will say otherwise... But to say that opposition is based on science and an alternate theory of the warming as oposed to opposition to the economics of the controls or some nefarious scheme by the scientific community seems wronf to me. |

My point is that technology does not get spread even all over this country, much less the world. The fact that cells and High-speed are not universal in China either further proves my point. They missed an opportunity or two. No they didn't. They missed a goat or two. The high populated areas of China have plenty of high speed and cell service. Just like the highly populated areas of the US. It's not a technological issue. It's an economic one. Furthermore you can get internet ANYWHERE in the US via satellite. It just costs more and is a little slower. For that matter you can get phone anywhere as well via satellite. Why is it the government's responsibility to provide cell phone and internet to EVERYONE. Not a necessity last time I checked. Again, see the example of rural electrification. Information access is completely analagous. No it's not. They have television (which provides a good deal of the nation's information) and if they want can get internet. Again it just costs more. Or go the the local library. Electrification was a necessity to grow these areas. FIOS is not. It's not analogous. Except that: TV news covers about 15% of the "news" thats available, and will only cover news that is able to sell advertising time. Web content is being designed with broadband in mind. Every day, the web is becoming more inaccessible to dialup. Using your reasoning, rural electrification shouldn't have happened, either. People could have had individual gensets to create their power. They can generate their own power, "it just costs more." |

Now they need to have a T1 hooked up to the farm? Come on. I'm not against information. I'd love everyone to have internet. But I'm not willing to subsidize what I consider to be a non-necessity (i.e. 10mbs internet) And we have gotten WAY off topic on this. I'm willing to move this to a new thread if you want...

Or is it just soemthing you're syaing that I have to take your word for? I'm going to assume you mean the claim that the upwards trend of warming has levelled off since 1998? The problem with this is that 1998 was an abnormally warm year (one of the warmest on record) and this 'pause' is only apparent if you start the trend on this outlying value. If you started the trend in either 1997 or 1999 you'd see it moving upwards, not pausing or moving downwards. The climate is not a linear system - the overall long term trend is upwards but natural variation from year to year exists. If you look at the data from 1987-1986 you'd actually see a cooling trend, however the long term trend over that period is still upwards. Sure if take the abnormally high year of 1998 and just draw a line to the cooler year of 2008, then it looks like the temp is decreasing over 10 years, but that's not a trend, it's just a line connecting two data points. When you include all 10 years of data between 1998-2008 into a proper trend calculation you actually get an increase although that's not that important since its short enough a time period to be dominated by natural variation. More importantly, when you look at the long term trend, which smoothes out the year to year variability the trend is increasing. This graph is using the NASA GISS data from 1980 to present. ![]() Short term trends are not significant indicators of climate but rather show short term variability within the long term climate trend. Now I'm making an assumption that this is your evidence that there hasn't been any warming over the past 10 years and it is based on this time period and short term trend. I apologize if I'm wrong and you have some other data you're basing your claim on. I hope that by trying to back up my claims with data and studies you can see I'm not trying to just dismiss out of hand any other argument. But showing where data are being interpreted incorrectly (such as with the 1998-2008 'pause') or studies that contradict other hypotheses (such as solar forcing being responsible for the warming) doesn't mean I'm deaf to any other possibility. Once again. just show me what is causing the warming of the climate (which incidently, even if this pause in warming from 1998-2008 WAS real, doesn't explain what has warmed the planet to this point) and why the additional GHGs we've added to the atmoshere AREN'T affecting climate at all. |

Expert ![]() ![]() ![]() ![]() | ![]() Renee - 2009-12-07 1:22 PM The growing concentrations in the oceans will become a problem long before we'll know toxic atmospheric levels that affect our breathing. actually we want more CO2 (and carbon) in the oceans . As the world gets warmer, the oceans can't hold as much CO2 (think how a cold soda keeps all the carbonation in it, while a warm one nearly explodes when you open it) and creates a negative feedback mechanism with the earth's cycles, it gets warmer, and releases more CO2, warmer, more CO2. A huge reason atmospheric CO2 levels have been so low when we started measuring them is because we have been coming out of an ice age. |

Champion ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() And according to history as CO2 levels rise there is usually a cooling period after the rise....Look at this graph...so based on the recording what do you see happening next? Any reasonably intelligent person is going to look at this and INSTANTLY see a pattern. A pattern of CO2 increase followed by a drop in temperature. Also the scale of these changes show how useless a 20-30 year graph really is. Zoom in on this graph and you can make it look really scary too. The trick of showing a small section of a graph (like the one Drew posted) is as old as marketing. You can make it look really bad depending on how you present the data. Of course the AGW groups will say "but humans have changed the plant and it will no longer follow the same pattern"... you can't win... ![]() Also I wanted to address the point that "no real scientists" dispute AGW.

Master ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() jimbo - 2009-12-07 10:17 PM i'm not sure how it could be the hottest decade on record without an increase in temperature. Dealing only with this statement. If the temperature plateaued at a high value, and held steady for 10 years, you could have "the hottest decade on record" without actually increasing the temperature over that decade. In fact, it could decline rather significantly, and as long as the rate of decline was smaller than the rate of the increase during the previous decade.... you would still have "the hottest decade on record." Or, you could have one year in a decade that was 10x as hot as a "normal" year, and then 9 years that were colder, and still have "the hottest decade on record." Or, if the warming continued you could have the "hottest decade on record." |

Master ![]() ![]() ![]() | ![]() drewb8 - 2009-12-08 10:50 PM NXS - 2009-12-08 7:05 PM The global temp hasn't risen for the last ten years. See what I mean Force? Ok, so what is your evidence for this claim? Or is it just soemthing you're syaing that I have to take your word for? I'm going to assume you mean the claim that the upwards trend of warming has levelled off since 1998? The problem with this is that 1998 was an abnormally warm year (one of the warmest on record) and this 'pause' is only apparent if you start the trend on this outlying value. If you started the trend in either 1997 or 1999 you'd see it moving upwards, not pausing or moving downwards. The climate is not a linear system - the overall long term trend is upwards but natural variation from year to year exists. If you look at the data from 1987-1986 you'd actually see a cooling trend, however the long term trend over that period is still upwards. Sure if take the abnormally high year of 1998 and just draw a line to the cooler year of 2008, then it looks like the temp is decreasing over 10 years, but that's not a trend, it's just a line connecting two data points. When you include all 10 years of data between 1998-2008 into a proper trend calculation you actually get an increase although that's not that important since its short enough a time period to be dominated by natural variation. More importantly, when you look at the long term trend, which smoothes out the year to year variability the trend is increasing. This graph is using the NASA GISS data from 1980 to present. ![]() Short term trends are not significant indicators of climate but rather show short term variability within the long term climate trend. Now I'm making an assumption that this is your evidence that there hasn't been any warming over the past 10 years and it is based on this time period and short term trend. I apologize if I'm wrong and you have some other data you're basing your claim on. I hope that by trying to back up my claims with data and studies you can see I'm not trying to just dismiss out of hand any other argument. But showing where data are being interpreted incorrectly (such as with the 1998-2008 'pause') or studies that contradict other hypotheses (such as solar forcing being responsible for the warming) doesn't mean I'm deaf to any other possibility. Once again. just show me what is causing the warming of the climate (which incidently, even if this pause in warming from 1998-2008 WAS real, doesn't explain what has warmed the planet to this point) and why the additional GHGs we've added to the atmoshere AREN'T affecting climate at all. Just a question. The Earth has been around about 4.5 billion years. So how is 1 year short term and 25 years long term? In relation to the Earth's existence aren't both time spans insigificantly short to determine a trend? Edited by Jackemy 2009-12-09 7:45 AM |

Master ![]() ![]() ![]() ![]() ![]() | ![]() From the article you linked to: ~~~~~~~~~~~~~~~~~~~~~ "Perhaps we sugegsted too strongly in the past the the development will continue going up along a simple, straight line. In reality periods of stagnation or even cooling are completely normal" says Latif. Despite they're current findings scientists agree that temperatures will continue to rise in the long term. ~~~~~~~~~~~~~~~~~~~~~~~~~ This 'pause' in warming only shows up in the Hadly data set (others such as the NASA and NOAA dtaa sets show a continued wamring) over this period, and only if you use 1998 as the start year. Why this discrepancy from the other data sets? Part of the explanation is that the Hadley data does not include observation from arctic regions and those are the areas that have shown the greatest amount of warming thus far. As mentioned in the article Jimbo posted, this same data set that showed a pause in the warming if you start in 1998 now shows that the last decade, starting in 2000 was the warmest on record, so if there was indeed a pause in the warming it appears to have started up again. |

Master ![]() ![]() ![]() ![]() ![]() | ![]() Jackemy - 2009-12-09 6:44 AM Just a question. The Earth has been around about 4.5 billion years. So how is 1 year short term and 25 years long term? In relation to the Earth's existence aren't both time spans insigificantly short to determine a trend? Well that was part of my point. One year, or even a 10 year period is not long enough to discern a long term trend from the natural variability within the system. And even 25 years is probably on the shorter end. When you're looking for a trend it all depends on what you're looking for a trend of. If we were trying to figure out whether we're entering another ice age or mot then it's appropraite to look at the timescale of thousands of years. if you are trying to determine whether the pollution controls you put on a power plant 30 years ago are wokring a time scale of 30 years would be appropriate (A longer period could give you the false impression of no trend if for example you start with a base condition 60 years ago, the power plant is built and pollution goes, then 30 years ago you put on controls and pollution goes back to the base level. Overall it looks like there is no trend and the controls aren't working, but if you look at the trend since you put in the controls you would see there are working). If you are looking at whether the climate is warming due to pollution we are emitting, we've only been doing that on a large scale for the past 150 years or so, so a trend of the last million years would be meaningless. A timescale of the last 150 years would be appropriate. If you wanted to know whether the rate of change ssince 1970 has increased or decreased then a timescale of 40 years would be appropriate. One note is that this has nothing to do with establishing causation, this is solely to determine whether there is a trend or not. |

Master ![]() ![]() ![]() ![]() ![]() | ![]() TriRSquared - 2009-12-09 6:27 AM And according to history as CO2 levels rise there is usually a cooling period after the rise....Look at this graph...so based on the recording what do you see happening next? Any reasonably intelligent person is going to look at this and INSTANTLY see a pattern. A pattern of CO2 increase followed by a drop in temperature. Also the scale of these changes show how useless a 20-30 year graph really is. Zoom in on this graph and you can make it look really scary too. The trick of showing a small section of a graph (like the one Drew posted) is as old as marketing. You can make it look really bad depending on how you present the data. Of course the AGW groups will say "but humans have changed the plant and it will no longer follow the same pattern"... you can't win... Also I wanted to address the point that "no real scientists" dispute AGW. Seems to me there are more than a few. I'm not sure what you are trying to show with that graph. As far as I can tell it looks like the peaks of temperature coincide with the peaks in CO2 and the decline in CO2 coincides with the declines in temperature. I don't see the lag you're talking about. if anything that graph seems to show a correlation between the amount of CO2 and temperature (although obviously correlation <> causation). Do you know of any studies which address this lag? Here is a longer term graph which starts about when we really started cranking stuff into the atmoshere using the same data set which showed the 'pause' which supposedly began in 1998 (1998 is that abnornally hot year near the end). ![]() And I never said no real real scientists dispute that we're changing the climate, there are a bunch of really smart guys who think that. But it's a small minority of those who are actively doing work on the subject. Edited by drewb8 2009-12-09 10:56 AM |
