No it doesn't. Just in one area. Can be five degree differences. Sorry that all is crapand global warming can't be found because there aren't enough stations around the globe to make that call. Unless of course you think there are and I would merely claim BS. But, convection and pressure systems moves heat around. Do you deny that? So the heat in Texas is moved to the north, do you agree with that? If not, there are very many Meteorologists that you are calling liars. And if you do agree, how do you find the actual local temperature if heat is moved, same for cold?I want to understand the TRUTHThat doesn't mean it's not 90% correct
And it doesn't mean it is 90% correct now is it?
Me personally, I don't understand why warmers are afraid of data that may help explain the climate. What's it to you? you have no solution so what is it your fearful of? Are you really that susceptible to someone stating doom and gloom on something that isn't even validated? Really? Wow.
Now, which is worse, saying something that is 90% correct, or shouting that everything is wrong because it's not 100% correct. How correct is someone who says it's all wrong and we should not do anything to solve the problem, because it's only 90% correct?
what is worse is someone that doesn't know for sure to disregard data that may be important and might influence further studies. I don't care what the percentage is. Or are you saying that scientists can't be wrong? LOL
I can say everyday of my life that rain is possible with some percentage. You know why? Because weather isn't settled. because the earth is unpredictable.![]()
No, it doesn't. I was giving an example, and used a figure.
You think I'm afraid of data? Why would you think that? You don't know me.
I want to understand the TRUTH. I've looked at lots of things and I've seen that there is a change in the climate. I also believe we should be going through a global cooling phase right now, though on that I'm never going to be certain.
But the biggest thing for me is that when humans start messing around with things, we find we're unable to stop them, and this causes massive problems.
It's all I want. It's a sad that people think they already know it. Now that is the problem. The science is not settled. AR5 states it. your IPCC not mine.
I've seen that there is a change in the climate.
what change in climate have you seen? how many years you been watching climate?
No, the science isn't settled. However on the one hand you have people looking for the truth, on the other people with agendas. Those with agendas might be on both sides of the debate, but lumping people with agendas with those looking for the truth is simply not fair, but happens too often.
Well, even within my own life time I've seen things get warmer. When I was a kid we used to have lots of snow, my father would have to dig out the roads in order to attempt to get to work. Now the only chance of getting stuck is when there is flooding.
But that's besides the point. This is science, this is far to complicated to see with the human experience. We're talking GLOBAL WARMING. Not localized warming.
What do you need to know the world is warming up? Readings from a station every two meters? No, you don't.
You can draw conclusions from less data. Perhaps that data won't be perfect, but it will tell you something.
Explainer: How do scientists measure global temperature? - Carbon Brief
"To get a complete picture of Earth’s temperature, scientists combine measurements from the air above land and the ocean surface collected by ships, buoys and sometimes satellites, too."

Here are the four groups who are studying the weather. The Japanese have lower global temperatures than others. Nasa has the highest. However they're pretty similar.
"The answer to this lies in how the different datasets deal with having little or no data in remote parts of the world, measurement errors, changes in instrumentation over time and other factors that make capturing global temperature a less-than-straightforward task."
"Data coverage has, perhaps, the biggest influence. NASA GISTEMP has the most comprehensive coverage, with measurements over 99 per cent of the globe. By contrast, JMA covers just 85 per cent of the globe, with particularly poor data in the poles, Africa and Asia."
"Nasa’s GISTEMP uses statistical methods to fill in gaps using surrounding measurements. How much each measurement influences the final value depends on how close it is geographically to the missing point. NOAA follows a similar process for the MLOST dataset."
"HadCRUT4 is the only dataset to leave regions with missing data blank, rather than try to fill them in. This effectively assumes temperatures there are in line with the global average."
So, the British don't fill in the blanks. Nasa fills in the blanks with statistical probabilities. What's the difference? The British have a lower set of data. If the Arctic is warming faster and the British aren't making statistical probabilities and perhaps have less data from the Arctic, then they get lower temperatures than they otherwise would.
"Indeed, updates to an old version of the temperature record (HadCRUT3) to include better Arctic data saw northern hemisphere temperatures rise by 0.1 degrees Celsius."
"The NASA GISTEMP record is the most detailed of the four datasets, with grid boxes two degrees longitude by two degrees latitude."
"The other three have grid boxes measuring five by five degrees. They also differ in how many land stations they have around the world, too. HadCRUT4 has about 5,500, GISTEMP takes middle place with about 6,300, but MLOST has the most of all, with about 7,000 land stations."
So, Nasa has the most accurate in terms of size of the area used to measure this data. NOAA has the most land stations.
"But scientists can use lower troposphere measurements as a further evidence of a changing climate. Several different groups now keep track of tropospheric temperatures and all four show a warming trend in the last 30 years."
So, basically, there are four groups collecting this data, they have a variety of ways of collecting, a variety of coverage, they're not perfect, but they give us a reading shows us, more or less, what is happening.
Now, you're denying because it's not 100% perfect, which is kind of ridiculous.
If we take localized statistics, in most cases we're going to see a rise in temperatures.

Central England.
![]()
USA
![]()
Australian sea surface temperatures.
We're seeing a rise EVERYWHERE more or less. There are a few places which aren't.
All the data is point in one direction. And then you're looking at the data and saying it's not 100% perfect, so let's forget EVERYTHING it's saying.
Why?
