At last a real discussion

warmist position “ YES ”
Thanks Willard.
Also a skeptic position is it not, so not much help there.

I am appreciative of your pointing out some of the difficulties in giving cogent arguments to every problem when some appear to have been rushed or not explained as well as they could be. Along with Izen we seem to be a tag team I was not expecting. Try some honey and lemon juice and lots of rest to get better quickly. oseltamivir Tamiflu®), zanamivir Relenza®) anti flu virus drugs might help if very crook??

Came across an Aussie? Steve Sherwood Director, Climate Change Research Centre, UNSW with a piece showing the problems with using the hot spot argument.
“” Climate meme debunked as the ‘tropospheric hot spot’ is found ” ** 2015
1. If you cannot find it, debunk its importance by saying it is a general sign of temperature increase, not a fingerprint of climate change.
2. If you can find it, insist on its importance as proof.
This article happily does both.

Quoting Skeptical science [abridged by me]
“Why should there be a ‘hotspot’ in the atmosphere above the tropics?
Most of Earth’s incoming energy from the sun is received in the tropics, strong evaporation there removes a lot of heat from the ocean surface. This heat is hidden (latent)
Strong evaporative uplift occurs near the equator due to the intense solar heating of the ocean there, forcing s the evaporated water (water vapour) to ascend up through the atmosphere. Because the temperature in the atmosphere decreases with increasing height (known as the lapse rate), this has the effect of cooling water vapor until it reaches a point where it condenses back into a liquid form (forming clouds and rainfall) – liberating the hidden (latent) heat into the upper atmosphere. With the great bulk of atmospheric moisture being concentrated in the tropics, this ongoing process should lead to greater warming in the tropical troposphere than at the surface.”

The problem
“Despite obvious warming of the atmosphere, it had been difficult to confirm the existence of this hotspot *” Skeptical science
The talking point?
The answer is not that any cause of temperature rise should give a hot spot.
But that a temperature rise seems to have occurred but the warming spot has not.
This then allows for doubt to be cast unfortunately on the measurements of temperature.
Which opens the whole can of worms, Joshua.
[” Show one “skeptic” point to be correct, and then show how that point being correct “adjudges” all “skeptic” arguments (or even a lot of them, or even one of them). “]

*primarily due to analytical deficiencies in accounting for temperature data quality and sampling, i.e. it’s suspected to have been a ‘measurement problem’. Skeptical science
**”The problem is that temperatures vary during the day, and when a new satellite is launched (which happens every few years), it observes the Earth at an earlier time of day than the old one (since after launch, each satellite orbit begins to decay toward later times of day).” Sherwood


Your comment is awaiting moderation.

But I do think that other authors haven’t considered the possibility that the “warmhole” is a consequence, not of a trend change, but of a sudden shift.

Thank you for pointing out this rather large shift or natural variation which goes to show that we do not fully understand the full range of natural variation available on this planet.
Was 2.1 C a 3 sigma shift?
Then we had a 5 sigma shift in the global sea ice last year with nary a viable reason put forward for a regime change.
Either we have much larger error bars than we realise or someone has mucked up the measurements.
CO2 certainly did not do a regime shift at these spots.

Take cars.
Subset electric cars.
I ride a pushbike in a flat, low density small city in a group of mainly over 60’s doing 3 -5 rides a week of 50 K and a coffee afterwards.
Tried to ride the 3 K to work at one stage but just too inconvenient.
We have accidents, fractured clavicles, head injuries hips etc And this is a group that knows how to ride.
Two cars, amazing how 2 people can never quite arrange not to be needed in 2 spots at the same time.
Nonetheless cars are an indictment on CO2 use, not a luxury if you believe in lowering it.
Yet everyone here is probably at least as complacent as I am.
Electric cars have to be manufactured, Tires engines seats glass. They have to be scrapped when they are old. They need fuel input from batteries which cost to make and dispose and if using solar power thay have to be manufactured as well and those things they use to transform the energy often breakdown and need replacing.
I do feel if you are going to talk the talk, you really must walk the walk.
If you read this on a computer, or reply to it you are not really doing your bit.
