As you said the air's humidity has an effect on how temp feels. We run a dehumidifier during the winter and it actually makes 69 feel warmer than a humid 69.


Evaporation is a cooling process. It's the body's way of cooling a person when it is hot. When the air is really cool there is very little humidity; the cold air cannot hold moisture. With no humidity, a person can survive at 45C for a while. If this were humid (wet bulb temperature) this would not be the case, and death would occur shortly.

Since 2000, the global CO2 average has grown by 43.5 ppm, an increase of 12 percent.


Your numbers are wrong! It has noting to do with Republicans or Democrats. CO2 increase is non political.

"Google the keeling curve. This is an ongoing measurement experiment. The data is peer reviewed, correlated across multiple sources, and extremely easy to interpret.

Average atmospheric CO2 in 1960: 315 ppm
Average atmospheric CO2 in 2020: 420 ppm

That's an increase of 105 ppm in 60 years, or a 33% increase from the 1960 number. Roughly 1.75 ppm, or roughly 0.5% per year.

Your 't***h' number is wrong."

It did that... and I was hooked on Robert Service. There was a TV movie (in the 50s) about the Shooting of Dan McGrew. My mom told me about it being a poem and that she had the book... that was all it took.

"Achieving air quality improvements requires cooperation from all countries, the chief polluter of which is China."

You have to take that into context. China's population is 5x that of the US. If you account for 'per capita' carbon footprint, the US is Number One by nearly a factor of two.

There will be a lot of research in battery types in the near future, I suspect. EVs are in their infancy.

It might not be Wordsworth, Keats or Lord Byron, but I like it. And it sounds like a reasonable request.


Our youngest son was homeschooled to an equivalent Grade 13, Honours English (Ontario had a grade 13 back then). He was 9 when he read "The Chronicles of Narnia". We've always been a family of 'books'. Keats and Schelley were some of my favourites. Kafka was one of my favourites and I made the mistake of letting our son know. This led to a darker side; he liked Kafka, too, maybe more than I did. This took him into the realm of Burroughs, etc. He even read Virgil's work...

An instance of his writing skills, I sent him a copy of an obit that was very unusual (it was a real obit): " Few obituaries begin with the words, "I am pleased to announce" – but Amanda Denis believes in blunt honesty.

When the Ontario resident's estranged father died halfway across the country in B.C.'s Okanagan, Denis felt compelled to share a few choice remarks about the man she describes as a "miserable human."

The obituary that resulted – which Denis ultimately had to publish on her own, after being rejected by her father's funeral home – clearly struck a nerve, getting shared thousands of times on social media.

"After suffering multiple strokes, one thankfully leaving him unable to speak, the abusive, narcissistic absentee father/husband/brother/son finally kicked the bucket," it reads.

"Because he treated people with disdain, there will be no service."

My son's response was, "De mortuis nil nisi bonum...but I never really believed in that saying, and the guy sounds like he was a proper bastard."

This demonstrates his literary skills.

Evaporative heat loss is a part of our loss of body heat, also.
Seems Australian researchers try to evaluate and enumerate that to include effects of humidity in their deep cold research measurements and chill factor tables.



Wet bulb temperatures are a means of including the effect of evaporative heat loss. With the world heating up, wet bulb temperatures will become increasingly important.

The air flow causes the heat to be removed from the surface, causing more heat 'to move' to where the heat was removed from... in simple terms.

...if you converted that amount of diesel fuel into electricity, it would only power a similar sized EV about 80-90 miles.


Most diesel locomotives that power trains convert diesel fuel to electricity.

"Diesel Locomotives use electricity to drive forward motion despite the name 'diesel'. A large diesel engine turns a shaft that drives a generator which makes electricity. This electrical energy powers large electric motors at the wheels called 'traction motors'. DC and AC Power: Some locomotives use DC generators and others use AC."

The centre of a high pressure area is generally calm... high pressure caused by cold air falling, as I understand.

Most of the temperature increase in the last 150 years occurred prior to 1940 when energy usage was a minor fraction of what it is today. How do you explain that.


Not correct... there is a direct correlation between CO2 content of the atmosphere and earth temperature, and most of the CO2 increase has happened since 1950.
