Evidence against warming from Carbon Dioxide

Day to Day Temperature Difference
Surface data from NCDC’s Global Summary of Days data, this is ~72 million daily readings,
from all of the stations with >360 daily samples per year.

y = -0.0001x + 0.001
R² = 0.0572
This is a chart of the annual average of day to day surface station change in min temp.
(Tmin day-1)-(Tmin d-0)=Daily Min Temp Anomaly= MnDiff = Difference
For charts with MxDiff it is equal = (Tmax day-1)-(Tmax d-0)=Daily Max Temp Anomaly= MxDiff
MnDiff is also the same as
(Tmax day-1) – (Tmin day-1) = Rising
(Tmax day-1) – (Tmin day-0) = Falling
Rising-Falling = MnDiff

Average daily rising temps
(Tmax day-1) – (Tmin day-1) = Rising

Day to Day Seasonal Slope Change

Throughout the year, especially in the extratropics, the length of time the Sunshines overhead changes.
Many have wished for some way to turn the Sun off for a while to see what surface temps do, well this happens daily.
You can see the balance of energy in the Earth system as the day becomes shorter, as well as see the length of day increase.
The surface temp responds to this with a change in temp, you can plot the rate of change for each station and look to see
if Co2 has altered the slope over the years.
If you plot daily MnDiff daily for a year, it’s a sine wave.

You can take the slope of the months leading up to and past the zero crossing,
both for summer (cooling) and winter (warming)
and plot thoses.
Global

Southern Hemisphere
is flat, other than some large disturbances in the 70’s and 80’s, and then again 2003.

Northern Hemisphere has a slight curve. A disturbance in 1973 when surface stations were changed,
And 1988

There are a number of regions with few stations, making some areas susceptible to large fluxuations,
or it could be a real disturbance in temps, they are timely to the transistions in the
Ocean cycles and the warm cycle and the start of the cooling cycle.

US Seasonal Slope
The US has the best surface station coverage in the world.

IR

Here is a sample of IR readings from a clear sky day, starting at 6:30pm, 11:00pm, 12:00pm, then 6:30am.

You can see how cold the sky is in 8u-14u, and how the surface warms and cools.
The ground cools until Sunrise.And the Grass acts as if it’s insulation,
ie trapped air allows the top surface to warm and cool quickly.
Yes this doesn’t show the impact of Co2, but you can add it back in, but even at that there is a big window open to space that is cold.

Max Rel Humidity limiting surface cooling.

The next night I measured the IR temperature of the sky during the night, and if anything it gets cooler through the night, while cooling slows with humidity.

At night, days of high humidity, as it cools off, Rel humidity
reaches near 100% at which point water starts to condenses out.

Over longer periods you can see how humidity cycles on a daily basis.

You can see this effect at my location (N41,W81) Depending on the path of the jet stream we either get tropical air from the gulf, or polar air from Canada.

This is good for a 10-20F swing in temps, and it is my opinion the oceans act as pins for the jet stream, which then effects the flow over the continents,
and these changes show up in the temperature record.

What I’ve done with surface station data, a modest weather station, and an IR thermometer the last 5-6 years.
