"They"...who are "they"? The four letter people?
You ask:
"on every square foot of the world".... on every square foot of the world"...ON EVERY SQUARE FOOT?
Imagine this:
Husband: "Oops, crushed a thermometer, oops, crushed another one"
Wife: "what is this idea of putting these thermometers on ski slopes anyhow?"
________________
Mr Abe: "Honey, I think the dog swallowed another one of these thermometers"
Veterinarian: "Hmm, it's a $500 procedure, hum...oops"
Mrs Abe: "What?"
Vet: "I think I crushed a thermometer"

Every hour we have to take barometric readings, sea and air temp readings, wind and cloud conditions and position of our ship and send them into some place that records and processes all that data. Thousands of ships around the world do this every hour.
The temperature two feet to my left is not that much different than that two feet to my right. No need to have a thermometer on every square foot of the world.
Good question. Climate scientists gather data from a limited number of ground based thermometers and use computer models to fill in the gaps. There used to be a lot more of temperature stations but for some reason the number has been cut drastically in the last 30 years. (Google "temperature station dropout")
It seems like a waste of time to use modeled temperatures to validate your temperature model but then I am not a climate scientist. One interesting side note is there are no temperatre stations in the entire nation of Bolivia. It's called "the Bolivia Effect." So whenever you look at a world surface temperature map, remember the temperature in Bolivia is not based on a single actual measurement, just what scientists think the temperature should be.
Edit: The weather station dropout issue seems to be the subject of heated debate with both sides claiming victory. One (apparently) objective measure is that the number of stations has dropped from 7000 to 1000. If anybody has other figures, I'd like to see them- with a link of course. Here's mine:

The temperature data is only useful if you need to know how much warming/cooling has occurred. There is far more observational data available to show that the planet is warming besides the temperature data. As Ottawa Mike has noted, wide spread and comprehensive deep ocean temperature data has been taking place for a decade or longer. Others have noted that SST data has been available with the advent of satellites. There have been centuries of sea surface temperature data available from ancient mariners to current times, at least along the shipping lanes and on expeditions outside of the shipping lanes.
I have yet to see you ask a question that did not also include your very wrong statements associated with them. Do ever get anything right that does not involve chance?
Satellites. They measure the temperature of every part of Earth’s surface (land and ocean) and have been doing so for the last 34 years.
There’s also a network of 12,000 ground stations and the seas and oceans are dotted with automatic devices that monitor temperatures both on and below the surface and transmit the results via satellites.
Every day there are literally billions of datapoints that are recorded, there’s so much information that it takes the most powerful computers in the world to process it all.
There are a minimum 1300 weather stations around the world reporting temps There are also satellite measurements. These are not as accurate but still verify trends
They have enough thermometers to get a representative sample of global temperature. They have enough thermometers to know a lot more than someone who looks out their window.
There are many ocean sensors floating around, check out the Argo network.
Satellites are used too. Longer term temperatures are inferred from sediments
Why do you keep making false claims before checking your 'facts'
?
They're not talking about global temperature anymore. That doesn't matter. They're talking about ocean heat content.
We've been accurately measuring ocean heat content to depths of 2000m for ten years. Oh well, I guess there's not much to talk about yet.
I guess you slept through the entire 20th century.
don't have a thermometer on every square foot of the world, none in the oceans, and we all know oceans are 70% of the world's surface?
