    You're not saying anything Tony.

    How does the current rate of warming compare to a natural post-ice-age warming?

    You know what, that is a pretty good argument for faster and more efficient rf protocols, although 5g as a brand is not quite that. For a brief stint I worked on wireless sensor data analytics, the protocols we have in place now are sufficient to manage autonomous vehicles on a city wide scale, if I had to take a SWAG ("scientific wild ass guess"). I would like to clarify that I'm very much in favour of the develop of better RF communication technologies, however SHF/EHF driven comm links are kind of a shit-show on the consumer level. I've seen rain and smoke knock out networks that use 30GHz+ frequencies. There are elegant solutions, I don't believe those solutions lie in the higher end of the RF band though.

    That is an excellent question and something I've been thinking about. The reason why scientists are investigating the effects of CO2 is the suggestion that the Earth is warming at extremely rapid rates. Having historically high rates of warming is a challenge to the claim that the warming is entirely natural and something I need to address.

    I'd question how meaningful the average air temperature is as a measure of the rate of warming, how accurate the number is and how unusual the rate of warming is historically. The fact that the warming of the Earth's atmosphere has slowed and stopped in the last few decades despite a continued rise in CO2 levels also deserves mentioning.

    @Faust's graph shows the rate of warming of the atmosphere from 2000 BC until now. The rate of recent atmospheric warming seems historically high compared to any previous warming in this time period. However, it could be natural for warming of the atmosphere to accelerate towards the end of an ice age because the rate of ice melting increases and humidity rises.

    The atmosphere might have been warming rapidly until recently but the rate of sea level rise of 3.3mm per year is historically very low. I think sea level rise is a better metric for judging the rate of warming than atmospheric temperature.



    The atmosphere has stopped warming and the sea level is rising very slowly. Why are people so alarmed? There is a real crisis of fear in the modern world, but that is a separate discussion.

    Sure. Okay.

    You forgot to zoom in on the end of the graph there, gdub:

    That looks like a scale distortion. The slope of the graph I posted for the section 11,000 to 9,000 years ago is 20mm per year. Your graph shows a rate of 2.1mm per year in the 20th Century.

    Your graph shows a rise of around 0.2m between 1000 AD and 1500 AD then another rise of around 0.2m between 1500 AD and 2000 AD. It looks alarming in relation to the flat section between 1 AD and 1000 AD. Maybe the flat section is highly unusual and what we are seeing now is nothing unusual over the long-term.

    Yeah anyway. I think you could talk in circles forever.
