Why Temperature Data in the U.S. does not agree with Global?

Question

The U.S. has 1221 USHC (U S Historical Climate network) stations located all over the lower 48. This are supposed to be one of the most up to date data collection systems in the world. They are all located away from urban areas to negate the effect of local heat islands.

When this data is averaged like the world surface data has been, it does not show the large increase the worlds average has reported. It shows not much warming over the past 70 years. This is when all the man made CO2 is supposed to cause dramatic heating.

How could this be? The US can't stay cool when the rest of the world is heating up. The article I read also said the US data correlates with the temperature data from the Sattelites measuring temperature which also does not agree with the large increase used by the IPCC.

Has anyone got info on this? I never read or heard about this before.

See CO2 SCIENCE.ORG - IT EVEN HAS LINKS TO THE DATA AT EVERY STATION. Interesting to look at all the locations in your own state.

Answer 1

There is evidence that the historical climate data is being altered even now.

http://surfacestations.org/
http://www.newsbusters.org/blog/noel-shepperd/2007/11/19/more-weather-station-shenanigans-media-won-t-report

it seems if the weather won't cooperate with what the global warming people want they will do anything to change the records to fit there global warming records.

i have noted that there has been a change in the sites for historical weather data to make it very hard to find a lot of the old data that used to be found on the Internet.
this started about 2 years ago.

one site was the historical temperature reading at NWC China Lake.
it used to show the data for the number of days that the temperature exceded 120 degs in the summer.
this data used to show a average of 15 days of 120+ degs.

in the last three years we have not had a 120+ deg day.
this looked bad for the global warming people.
so they took the daily temp records off the site.

Also the CO2 records have been altered

Answer 2

Based on what I have learned as a layman, I believe that recent global temperature data taken at measurement points is somewhat less than 100% accurate, but is sufficiently accurate to give us a clear indication of the trends. I do not think that data has been falsified; I believe it is crucially important that research continue and is refined and that we adopt reasonable measures to mitigate potential impact(s) mankind has on the climate. I do not have enough background in the sciences or the resources to analyze global temperature data taken from ice cores, etc, but my understanding is that the data that is being assembled is giving a fairly consistent picture of global temperatures and conditions in the distant past. Although I have a nodding familiarity with how climate records are gathered and anaIyzed, I would be interested in learning more about how that information is derived from the records found.

I just spent several minutes at the USHCN web site and I could not find where they keep the overall averages for easy access by the general public. I just got a bunch of open browsers that kept me going around in circles. By easy access, I mean have what I'm looking for right there with one or two clicks and not have to decipher all the acronyms and other jargon they use on that site.

Have you tried the "Contact Us" link to inquire with someone who works there? I think you'll get a more helpful answer if you could get to know and communicate with someone in that agency. What are the odds of someone from there going through these Yahoo Answers? My guess - very remote. But you got my curiosity for how you arrived at the conclusion you're asking about in your question.

Answer 4

Actually, your statement about the temperature equipment being located away from urban environment is incorrect. Many of the US measures are taken in an artificially warm environment (of course this is rarely brought up in the main stream media).

Notice the use of lava rocks, asphalt, and other warming agents near measuring stations. My personal favorites are the ones located on the roofs of building. I bet those measurements precisely measure the outside air temp. ROFL

Answer 5

All you have to do is look at the two top stories on yahoo science nrews for the real answer. First one says that all across the US, record heat was the norm. The story title is..'2007 A year of weather records in the US.' Check it,then go ahead and spout your ignorant rant!

Answer 6

Like the other people who would replied I would like to see your reference to this, please.
The graphs at http://www.epa.gov/climatechange/science/recenttc_triad.html are issued by the United States Environmental Protection Agency.
They are very similar but not identical to those included in the Stern Report

Answer 7

Notice how the global warming "theory" all began after the fall of the Soviet Union.(1991) hmmm..... I wonder how that happened. But yea.... It's just because all the weather stations that were in the former USSR had been shut down so we lost a large amount of our reliable temp. data.

Answer 8

I believe that we are obsessing about global warming. I would rather have global warming than global cooling..How would it be if we were looking forward to another Ice Age with the US covered with glaciers on a year around basis?

Answer 9

Satellites are limited to iridescence imaging only, they can't and never will be able to monitor the upper atmosphere of the planet.That being said we are limited basically to ground level testing which in it's part is inclusive.Sure you have weather balloons but they are also limited to the lower atmosphere also.This is what has led to disputes over climate change and scientist arguing with scientist.

Answer 10

when they say a large increase, they mean usually just a few degrees, if the earth was to heat up say 7 more degrees we would all die, and global warming isnt just about the diffrence in temp. its about the o-zone layer, and the ice melting in the arctic.
