There is no such thing as 'man made climate change'.

In the last 2 MM years we have had 17 ice ages; roughly one over 100,000 years It gets cold then it warms up-we are coming out of an ice age so of course the earth gets warmer-till it gets colder again-it's a cycle.

75,000 years ago there only 22 human couples were alive in an ice age. Now we have 8 billion people, obviously, a warmer climate is good for humans.

Finally C02 is good for humans, animals and plants:

"Plants use energy from sunlight to fuse a molecule of CO2 to a molecule of water,

H2 O, to form carbohydrates. One molecule of oxygen O2 is released to the air for each

CO2 molecule removed. Biological machinery of plants reworks the carbohydrate

polymers into proteins, oils and other molecules of life. Every living creature, from

the blooming rose, to the newborn baby, is made of carbon from former atmospheric

CO2 molecules. Long-dead plants used CO2 from ancient atmospheres to produce

most of the fossil fuels, coal, oil, and natural gas that have transformed the life of

most humans – moving from drudgery and near starvation before the industrial

revolution to the rising potential for abundance today.

The fraction of the beneficial molecule CO2 in the current atmosphere is tiny,

about 0.04% by volume. This level is about 30% larger than pre-industrial levels in

1800. But today’s levels are still much smaller than the levels, 0.20% or more, that

prevailed over much of geological history. CO2 levels during the past tens of millions

of years have been much closer to starvation levels, 0.015%, when many plants die,

than to the much higher levels that most plants prefer. Basic physics implies that

more atmospheric CO2 will increase greenhouse warming.

However, atmospheric processes are so complicated that the amount of

warming cannot be reliably predicted from first principles. Recent observations of

the atmosphere and oceans, together with geological history, point to very modest

warming, about 1 C (1.8 F) if atmospheric CO2 levels are doubled.

Observations also show no significant change in extreme weather, tornadoes,

hurricanes, floods, or droughts. Sea levels are rising at about the same rate as in

centuries past. A few degrees of warming will have many benefits, longer growing

seasons and less winter heating expenses. And this will be in addition to major

benefits to agriculture.

More CO2 in the atmosphere is not an unprecedented experiment with an

unpredictable outcome. The Earth has done the experiment many times in the

geological past. Life flourished abundantly on land and in the oceans at much larger

CO2 levels than those today. Responsible use of fossil fuels, with cost-effective

control of genuine pollutants like fly ash or oxides of sulfur and nitrogen, will be a

major benefit for the world. (1)"

Thank you Julian.

I would certainly call you a "Nerd", a title which i carry too, as "a name of honour".

My 40 year career in IT brought me into contact with many Nerds, in the basements of the high rising temples of the Corporations, where they mostly keep the corporations running.

Without those "Nerds" we would not have had the Internet (but also no derivatives).

I assume that the Washington Neocons are working without Nerds in the basements (whistleblowing danger). That would explain their blind race towards the Abyss...

Autism is a creation of Evolution, the Force of Real Change.

I have restarted my work on "The falsifiable hypothesis of the Cause of Autism and the resulting creation of the Autistic Brain. How it starts and develops and how all (most) of the autistic symptoms can/could result from that."

Evolution plays an important role in this and it is influenced by and has influence on the story of humankind in the last 200.000 years (or even a bit more).

But it means too, that i will not react very much in Substack any more. The Social aspect of that work takes too much time causes overstimulation of parts of my brain and i always have the feeling that i could not express what i wanted to.

Creating Tweets from your posts will continue. It is created while reading your posts.

And ofc i might still react on some comments that for me stand out.

Keep on doing the good work !
