This is interesting. A new study, to be published by the American Geophysical Union, suggests that waste heat output correlates better with temperature changes than do climate models.
Important study: Waste heat is a major source of national warming, significantly pollutes climatic record
I covered a similar study back in 2008 which you can read about here. This study takes it to a national level, suggesting once again that surface temperature records are not really measuring a “climate change” signal in entirety. The author of the study says that “correlation of temperature above background levels and national energy…

From Urban to National Heat Island: the effect of anthropogenic heat output on climate change in high population industrial countries
John Murray, Douglas Heggie
Key Points:
• Annual heat output for the U.K. and Japan is determined from national energy consumption 1965-2013
• Strong correlations are found between energy consumption and temperatures above or below global background levels
• Heat output may affect climate change in countries of high population density
Abstract
The project presented here sought to determine whether changes in anthropogenic thermal emission can have a measurable effect on temperature at the national level, taking Japan & Great Britain as type examples. Using energy consumption as a proxy for thermal emission, strong correlations (mean r2 = 0.90 & 0.89 respectively) are found between national equivalent heat output HO and temperature above background levels ∆taveraged over 5 to 8 year periods between 1965 and 2013, as opposed to weaker correlations for CMIP5 model temperatures above background levels ∆mt (mean r2 = 0.52 & 0.10). It is clear that the fluctuations in ∆t are better explained by energy consumption than by present climate models, and that energy consumption can contribute to climate change at the national level on these timescales.
Just think about all the radiators on every car that goes by ransfering that waste heat to the air, about 80% of the energy in the fuel that all cars use just gets transfered to the air as heat..
Pretty much all power is derived from heat.. Burning coal, nuclear power, natural gas.. All heat..
Pretty much all the energy you use also eventually winds up as heat because of the laws of conservation of energy. The wind resistance to your car, your TV, vacuum, everything..
You do realize the warming predictions that were too high were .21 C per decade?Total waste heat accounts for .1 to .2 degrees per decade toward Global Warming.
Total waste heat accounts for .1 to .2 degrees per decade toward Global Warming.
Where did you get this?
Calculate the annual waste heat from petrocarbon fuels. Calculate the weight of the Atmosphere. Calculate the temp increase caused by the heat waste btus. Big numbers, but not rocket science.
Do it up..

Big numbers, but not rocket science. My answer was in farenheit degrees.
Let's use logic instead. If you leave the heat on in your trailer, it's gonna get hotter.
Show your work
No, how about since you brought up calculations we use math.
I told you how. Do the work.
I did the math and came up with 10^-7 C.
I think you neglected the waste heat form biomass, coal, nukes and ethanol.

I blame Léonard Carnot!And we produce a great amount of waste heat, and it gets greater every year.

Concrete is a high use high heat item as it sets. Then also add land use changes of asphalt, concrete, and buildings that replace vegetation. The severe loss of transpiration, replaced by black body absorbers.
Have you guys seen charts like this?
Global primary energy usage: 524 quadrillion BTU per year = 5.24e17 BTU/yr = 1.75e13 J/sec = 1.75e13 Watts.
Earth surface area: 5.10e14 m².
Global waste heat from energy use: 1.75e13 / 5.10e14 = .034 W/m².
Global heat from anthropogenic greenhouse gas emissions: 2.974 W/m².
Percentage of global warming due to waste heat: .034 / (2.974 + .034) = 1.1%.
