... "Lets look at the temperatures in the arctic where a lot of the warming has taken place.
... The warming is during the winter.
There has been virtually no change in the summer.
... one (reason) is the ice melting and water freezing processes.
When ice melts, it takes energy from the air so in effect it retards warming.
That would be occurring in the summer season.
When there is a refreezing, it’s the opposite.
... But why would the winter arctic temperatures be so much warmer?
The answer is water vapor.
Slight increases in water vapor produce greater increases in temperature correlation.
We can see that by looking at saturation mixing ratios, of grams per kilograms of WV.
... slight increases in WV affect where its cold and dry much more.
... the increase is so small in water vapor that it has had much less effect on the global temperature than the contribution from the Arctic and Antarctic winters!
... if we can visibly link water vapor to the temperature and changes in the weather and climate,
and we have no such linkage of CO2 to temperature,
how is it CO2 would have the finger pointed at it for what is plainly the domain of water vapor?
... What is the Water vapor vs. CO2 as a climate control knob?
The simplest answer to the problem?
Is it the complexity of the addition of 1.5 gram/kg of CO2 over what is almost century to the atmosphere,
that is perfectly capable of adapting,
or the dominant forcing mechanism of WV (water vapor)? ...
... But who knows what the true equilibrium is anyway, just like who knows what the perfect temperature or amount of CO2 in the air optimum for plant and animal life?
No one.
How is it what was a climate optimum in previous years is somehow a climate crisis now?
So why would we spend trillions of dollars chasing something that has not been defined?
The old definition of weather and climate simply being nature’s attempt at finding a balance to a chaotic system
where balances are impossible to maintain because of the design of the system,
says of course there will be ups and downs ranging from hours to centuries.
But as in all things in nature, the dominant forcing has the dominant effect
A few practical examples.
Lets just take US Summer temperatures over the last 10 years.
Using the temperatures vs the averages from 1961 to 1990 you can see how much warmer it is.
... when we look at maximum temperatures we see the warming is not as great as minimum temperature, except in the west.
... Nightime lows are visibly higher
Now why would this be?
Well lets look at precipitation:
Contrary to all the yelling and screaming about a dust bowl it has been wetter in much of the nation where we grow our food.
... The West has been drier so it is hotter by day.
The eastern and southern warmth at night is a product of higher moisture content in the air.
The heavier precipitation means the dreaded heat dome that occurred in the 1930s aloft (... just how did that occur with CO2 so low?) has not developed.
... the higher amounts of WV due to the cyclically warmed oceans, is putting more WV in the air, which affects temperatures more when they are lower.
... But let us not cherry pick the US.
The last 10 years are the “hottest decade” on record, correct?
... since when is a degree warmer over as long a period of time, and mostly in places cold and dry, hot?
... In the past 40 years we have warmed about +0.14C. per decade (UAH)
... taking a half degree C intervals, where can all of this warming be seen?
... it’s the arctic.
What about summer?
Not nearly as much.
... why do climate alarmists not quantify the increase of WV to where the temperatures are warming, when they are warming, and by how much?
Because there is no provable linkage to CO2,
just a hypothesis that is being accepted in the face of what may be a simple, demonstrative cause and effect,
the much larger greenhouse gas, Water Vapor.
... The idea they (climate alarmists) are pushing is that CO2’s attribution to the climate is far more important than the larger members of the system,
the sun,
oceans,
stochastic events, (try a couple of well placed volcanoes sending ash into the stratosphere over the tropics)
and the very design of the system which is always at odds with itself.
... As the agenda gets more extreme, the canceling of skeptical voices grows. ...
