>Have we entered an era of global cooling?

We can empathically answer that as a NO

Valley Guy. I take it you are a highly credentialed climate scientist able to refute the combined scientific ecumene of NASA And their solar observation/weather satellites.

Scientifically, I'd rate you still stuck in the dark ages on a flat earth, with "rocks" for brains/echo chamber.

The Roman Peak was around 0AD which had Rome at its peak.
Then Rome declined down to around 450 500 or so AD with falling crop
yields. Then the well known Medieval Warm period 1000 when the Vikings
settled on Greenland and started knowledge of Nth America.
They packed up and left around 1400 as it got too cold to farm in
Greenland. Then another 400 years later the Little Ice Age
arrived around 1800.
The cycle seems to be between 800 years and 1200 years long.
So I think it is too soon to expect a drop in temperature.
We probably need to wait another 100 years or so to feel the chill.

This cycle has been known for years and years but the global warmers
don't want to know.
Some scientists believe it is made up of multiple cycles.
The Milanovitc cycles the variation in cosmic rays modulating cloud cover and of course to quote someone "Its the Sun Stupid !"

There is no such thing as a "climate scientist".

Geologists are the closest to such a description, and their evidence has told us the climate mumbo jumbo is hysterical crap and lies.

Fortunately climate change deniers are a tiny but veracious minority. And will not prevail against the voting majority.

Change need not tank the economy, just the very opposite.

Change cannot include the asinine labor renewables (cult) ideopolitical imperative solution, which will tank the economy and destroy essential local economy dependant, discretionary spending.

Change must include nuclear power as MSR thorium and with it PKWH prices as low as 3 cents or less. Or as MSR nuclear waste burners almost free, burning mostly unspent fuel we are paid millions to take.

If it matters, both those options are also carbon free. And will create a new manufacturing economy here at home that ends our insane reliance on China for manufactured durables. We could have a car manufacturing industry again and an aerospace industry that manufactures planes and space craft.

We can also have all manner of heavy industry and a defence self reliance industries that we can afford!

When the energy bill became higher that the wages bill, most industry headed offshore. We can reverse that in spades and resuscitate our manufacturing sector, always provided we can get rid of (Chinese loving) labor!

Agree Alan, we are being led by the nose to disaster.
However climate change is a fact but it has nothing to do with co2.
Unfortunately the upsurge in the use of coal at the Little Ice Age
minimum 0f 1800 coincided with the start of temperature rise in the
current cycle.
There you are said the co2 fanatics just as the Industrial revolution
got under way.
And they still haven't twigged !
It is like the electric car introduction is thought to be because
of co2 raising the temperature. It was going to happen anyway.
The electric car introduction came about because the car makers were
given the drum by the oil companies. The last thing they wanted to do
was design a whole new range of cars.

Sometime in the next 100 years or so it will become obvious that the
whole global warming stunt was not real but a major blunder !
