Chilling climate revelations from a previous ice age

About 14,000 years ago, the southwest United States was lush and green, home to saber-toothed cats and mammoths. Meanwhile, the Pacific Northwest was mostly grassland.

That all changed as the last ice age was ending. Climate changes might be expected with the melt of a global freeze, but what’s surprising is how quickly climate and rainfall patterns changed. According to research published Nov. 22, the collapse of an ice sheet in what is now western Canada triggered a reorganization of the jet stream over the course of about 100 years — a blink of an eye in geological time.

Leaky vaccine, leaky vaccines

  The term does appear, on exactly one page, the one about 

Marek's disease

"The Marek's disease vaccine is a "leaky vaccine", which means that only the symptoms of the disease are prevented.^[12] Infection of the host and the transmission of the virus are not inhibited by the vaccine."

Which is odd since a leaky vaccine is such an important thing, and potentially a very dangerous thing.  

Imperfect Vaccination Can Enhance the Transmission of Highly Virulent Pathogens

‘Leaky’ Vaccines Can Produce Stronger Versions of Viruses

Many livestock and human vaccines are leaky because they block symptoms but do not prevent infection or onward transmission. This leakiness is concerning because it increases vaccination coverage required to prevent disease spread and can promote evolution of increased pathogen virulence

Just added the name to the article on Croll.  We will see if it will be found on Wikipedia

Snow ratio (not found on Wikipedia) updated Nov 29 2023

 Snow ratio, not found on Wikipedia. It's the ratio that depends on the air temperature, that means the colder it is, the more snow there is from the amount of precipitation/

Colder temperatures create more snow from the same amount of liquid water.  

A very important thing to know in meteorology, or snow science.  Does not appear on Wikipedia.  (this is actually a huge failing, just huge)

You might think it would be in the snow science page

https://en.wikipedia.org/wiki/Snow_science

Nope.  Also can't be found searching wikipedia.

https://en.wikipedia.org/w/index.php?search=snow+ratio&title=Special%3ASearch&go=Go&ns0=1

Or using Google to search Wikipedia

Isn't that something?
