New Study Finds 25-45% Of The Instrumental Warming Since The 1950s Is Due To Urbanization — NOT CO2

https://www.climatedepot.com/2021/02/17/new-study-finds-25-45-of-the-instrumental-warming-since-the-1950s-is-due-to-urbanization-not-co2/

Why have sea surface temperatures and proxy temperature reconstructions so strongly diverged from the instrumental land record in recent decades? Because “0.36 ± 0.04 °C” of non-climatic warming from roofs, asphalt, machines, vehicles…artificially enhances the post-1950s global temperature trend.
A new analysis (Scafetta, 2021) suggests:

• Urban Heat Island (UHI) effects can raise city temperatures 6-9°C above the temperatures in surrounding rural areas. These significant biases are not sufficiently removed from instrumental records.

• Sea surface temperatures and land temperatures showed matching variations and amplitudes from 1900 to 1980. After 1980, the land surface temperatures rose substantially more, suggesting nearly half of the land temperature increase is non-climatic.

• Tree ring temperature reconstructions showed a strikingly similar pattern of amplitude and oscillation prior to the 1980s. After the 1980s, the instrumental record claims more than twice as much warming as the proxy records.

• Between 25-45% of the warming from 1940-’60 to 2000-’20 appears to be artificial, or non-climatic.

• Climate models overestimate the 1940-’60 to 2000-’20 climatic warming by about 40% in hindcasts.

This is not new news. There were studies on this 20+ years ago. Most of the stations where temperature data has been gathered over a long period of time are in places that turned into cities over time. Localized warming due to surface coverage. Its common sense really.

Oh, so humans DO have a major impact on climate after all.

Hal baiting with stupidity.

Localized temperature rise due to urbanization does not equal major impact on global climate.

 

[hal9000]

This paper doesn’t say what you think it says

yes, when you surround a thermometer with concrete, asphalt and A/C exhaust it will read higher temperatures.

 

[Autoprax]

yes, when you surround a thermometer with concrete, asphalt, A/C exhaust, and stick up your butt, it will read higher temperatures.

 

[Duffy LaCoronilla]

If it’s 100 degrees ambient and you stick a thermometer in your culo the temp reading will go down (assuming you’re healthy).

Put another way, between 55-75% is not from that.

yes exactly that too.

and, based on my first reading, it’s mostly based on mathematical modeling.

I have to read things a bunch of times because I’m a dummy.

I have no idea how I got through grad school.

and yet we still have ocean acidification and glacier loss in places nowhere near urbanized zones

weird...I wonder how that happens.

CO2

but all the CO2...where does it come from?

did the Durham Investigation release the CO2

Your source (IMHO is suspect)- https://en.wikipedia.org/wiki/Marc_Morano

He began his career working for Rush Limbaugh from 1992 to 1996.[5] After 1996, he began working for Cybercast News Service (now CNSNews), where he was the first to publish the accusations from Swift-Boat veterans that John Kerry had allegedly exaggerated his military service record.[4]....

In April 2009, despite having no formal education in the field of climate science,[7] Morano founded and became executive editor of ClimateDepot.com, a website sponsored by the Committee for a Constructive Tomorrow (CFACT)....

Morano mocks scientists in television debates, which he describes as fun. In one blog post he wrote "We should kick scientists when they're down. They deserve to be publicly flogged", but then said "come on, it was a stupid expression." While some climatologists who felt they had been bullied were reluctant to give their names, Michael E. Mann openly said that Morano "spreads malicious lies about scientists, paints us as enemies of the people, then uses language that makes it sound like we should be subject to death threats, harmed or killed."

 

[hal9000]

Scafetta’s work does not seem to be corroborated by that of other scientists , nor does he offer any mechanisms to support his hypotheses. He seems to currently lack credibility due to a lack of scientific evidence to support his claims.

Credibility.....it's a thing.

I linked the actual study (Nicola Staffeta).

Mark Morano is just the delivery boy.

MSM would never report this, EVER.

Does not jibe with narrative and agenda.

As for other aspects of AGW mentioned, we are still emerging out of an Ice Age and slow but steady warming would be happening, Industrial Revolution or not (glaciers receding and other long term melting).

STILL waiting to see even a HINT of accelerated sea level rise rates. Number 1 hype of AGW for impact to humans.

Humans contribution to actual toxic polluting of the planet is a MUCH worse problem than its contributions of CO2. Climate effects are no where near as significant as hyped.

But look, look over there at that CO2 from USA SUV's.
Pay no attention to all the increased toxic pollutants the 3rd world is spewing while building our (and increasingly their) precious fad gadgets.
