Were the averages from TWC based on NOAA's data, or from NOAA? What did they use for the "average"? Average daily temperature, average high, average low? Did they consider the time of day at which the readings were taken? Because that kind of thing can make a difference.
I copied monthly averages they had on TWC sourced from NOAA for where I live as a starting point. Then I took the raw numbers and calculated an average. In every case NOAA's average was 3 degrees higher than the real number from raw data.

Again NOAA. Are they all time highs, or just the highest recorded accurately in recent times, since real data has been measured and kept instead of relying on anecdotal evidence.
Remember the NOAA averages are given out already weighted, factoring in data that is best guess at best IMO.

Total BS without Exact Scientific Evidence . Has the UN also started Mining Green Cheese on the Moon yet ?
It's all in the public record to see. Here are two for you:
UAH lower troposphere data:
1970s Mean : -0.284583 (1978 & 1979)
1980s Mean : -0.142167
1990s Mean : 0.00125
2000s Mean : 0.10425
2010s Mean : 0.223583 (through May 2017)
Radiosonde surface data going back to 1958, which shows a much larger change:
1950s mean: -0.05 (1958 & 1959)
1960s mean: -0.118
1970s mean: -0.13
1980s mean: 0.06
1990s mean: 0.185
2000s mean: 0.352
2010s mean: 0.739 (through 2016)

That's exactly my point. Science is not a consensus. We had scientists warning us about global cooling and the coming ice age, we had scientists warning us about global warming, we had scientists predicting all major marine life would be extinct before 2000, and we had scientists warning us that the coasts would be uninhabitable because of the stench of rotting marine life.
Think critically is all I ask.
Almost 20% of people approve of Congress.
There are always a few cranks out there - in any field.
What an off-topic post...
Clearly you either didn't read the post I responded to or understand the response.
Clearly , I did not feel the need..

Yuma is hell on Earth. I honestly don't know how or why people live there. It has always been one of the hottest cities in the world.

Yes. The Earth has been warmer in the past.
That's your point.
Ok.

I Love it here!
Of course, it did take me a full 5 years to get acclimated. Been here full time about 30 years now.
At least when I say I'm on the border, you know I really am.

Yeah. "Heat islands."
Cities are indeed often warmer than farmlands
Thing is, stations in rural areas show the same trends as those in cities. Both are getting warming.

I was born and raised in the NM bootheel, had relatives in Yuma and worked for awhile in southern AZ out of college. No thank you! I got my fill of that crap my first 24 years of life.
My folks' place in NM has seen 120 degrees and its seen -20 degrees (thankfully not on the same day, LOL). Those high country deserts will kill you if you're not tougher than an old boot.

The degree of change is entirely dependent on the baseline, which is why these types of statistical recordings are used rather than actual temperatures given. Pick a particularly cool year as your baseline and a hot year looks SCORCHING. Pick a particularly warm year as your baseline and a cold winter looks FRIGID.
At no point in this planet's history has the climate remained stagnant... Even where record highs and lows are concerned, there are factors which play a major role. For example, concrete and asphalt act like heat sinks... the more development occurs around a city's temperature recording station over the years, the more latent heat that station will record whether the actual day was warmer or not. It's why you place rocks around a campfire ring... your food cooks faster than it does over a fire laid on the ground with no rocks to collect and radiate the heat from the fire. The fire itself stays the same temperature.

Saying humans are responsible for only 3-4% of CO2 emissions is factual, yet it's also misleading.
For example, plants are carbon-based lifeforms, and as such, plants need oxygen to breathe. When any carbon-based organism respires, it emits carbon dioxide (P+). Fortunately, plants also photosynthesize, and their collective CO2 output is roughly half of what their collective CO2 intake is (P- = (P+ * 2)).
The oceans also emit carbon dioxide due to various processes (O+), but they too take up more CO2 from the atmosphere than they release to the atmosphere - albeit only around 2% more (O- = (O+ * 1.02)). Oceans emit approximately 50% more CO2 than plants (O+ = (P+ * 1.5)).
Various life and other chemical processes on land release more CO2 than they consume, which is almost equivalent to the net CO2 removed from the atmosphere by plants and the oceans (L+ = (P- + O-) * 0.995).
Volcanic eruptions on average are included in land release (L+), but make up only a small portion of CO2 emissions (V+ = (P- + O+) * 0.001). However, some massive eruptions in the distant past emitted far more CO2 for a brief period - perhaps ten to twenty times the annual average for thousands of years. These eruptions dated geologically correspond well to increased CO2 levels, but also to mass extinction events in the fossil record.
You can see from this that we have a small buffer for human CO2 emissions, where CO2 levels would remain nearly static (B = ((P- + O-) - L+)). However, human emissions are not included in this calculation. The addition of human CO2 emissions is rather significant - they're approximately 1/10th of what all plants on Earth combined emit (H+ = (P+ * 0.1)).
This is where we have a problem, because human emissions greatly exceed that buffer (H+ > B):
H+ = (P+ * 0.1)
P+ = (H+ * 10)
P- = (P+ * 2) = ((H+ * 10) * 2) = (H+ * 20)
O+ = (P+ * 1.5)) = ((H+ * 10) * 1.5) = (H+ * 30)
O- = (O+ * 0.98) = ((H+ * 30) * 1.02) = (H+ * 30.6)
L+ = (P- + O-) * 0.995) = (((H+ * 20) + (H+ * 30.6)) * 0.995) = ((H+ * 50.6) * 0.995) = (H+ * 50.347)
B = (P- + O-) - L+)) = ((H+ * 50.6) - (H+ * 50.347)) = ((H+ * 0.253))
H+ > B = H+ > (H+ * 0.253)
As you can see, our emissions are exceeding the buffer by nearly 400%, despite only making up about 4% of total (natural and human) annual CO2 emissions.
There is some elasticity in where CO2 goes, as our emissions don't increase atmospheric levels at the same rate as we emit CO2, but we can clearly see through tracking atmospheric CO2 levels that total CO2 in the atmosphere has been increasing at a rate of over +0.5%/yr.

So global warming isn't a thing ?
Sure. It sure does get hot and hotter. But is that man-made?
The Earth has gone through cyclical climates for millennia. Didn't you learn that in elementary school? We had a fairly recent iceage, so now the sea level is rising, and that's normal.
We've only been recording temperatures for a very short period of time compared to how long we've survived these climates.
Except actual Scientists look at ice core samples and tree rings and other indicators and have a pretty good idea what the climate was hundreds, thousands, even millions of years ago. Actual scientists have written thousands of peer reviews scientific papers that indicate that most of this recent warming is man made. I learned in school that it's generally good to listen to scientists over bloggers and news pundits.
Except "actual scientists" don't agree on this. As a matter of fact "actual scientists" are very very often wrong. I implore you to go back to the 70's and listen to what "actual scientists" told us about where we'd be at today. Seriously, do it.
That said, I'm an "actual scientist" because I've been in the field observing physics for decades.
Btw, "you learned in school" xyz. I learned in school that white people were devils, that Al Gore was a prophet, and that the most important part of journalism is selling the story over facts. Be careful of what people teach you. Think critically.

In some cases what you say is true, certainly.
But that whole "heat island" excuse is pretty much dead, except for the die hard deniers.
Can I chalk you up for one who doesn't think the world is warming then?

As an engineer, I cannot take the global temperature crisis seriously because I have done due diligence on the subject.
What equipment was used to measure the temperatures?
What variance studies were conducted to ascertain the differences in equipment over time?
What calibrations were done on the equipment?
Who collected the data? Were they vetted?
