Boreal winter, boreal summer, still no entry

The terms are used of course, it's just that there is no entry or explanation of them.

Example

 The NECC has a pronounced seasonal cycle in the Atlantic and Pacific, reaching maximum strength in late boreal summer and fall and minimum strength in late boreal winter and spring. Furthermore, the NECC in the Atlantic disappears in late winter and early spring.[2]

Here's how easy it is to explain it when using it.

Criticality

I know, hard to believe.

Criticality is a nuclear term that refers to the balance of neutrons in the system. “Subcritical” refers to a system where the loss rate of neutrons is greater than the production rate of neutrons and therefore the neutron population (or number of neutrons) decreases as time goes on.

The Holocene temperature conundrum (edited May 5 2021)

The paper (no longer works)  The paper --> archive.org ... another link to the paper

"The question is, 'Who is right?'" Liu said. "Or, maybe none of us is completely right. It could be partly a data problem, since some of the data in last year's study contradicts itself. It could partly be a model problem because of some missing physical mechanisms."

This mystery is known as the "Holocene temperature conundrum," and it describes a debate that has gone on over how temperatures have changed during the Holocene, an epoch that describes the last 11,700 years of our planet's history. While some previous proxy reconstructions suggest that average Holocene temperatures peaked between 6,000 and 10,000 years ago and the planet cooled after this, climate models suggest that global temperatures have actually risen over the past 12,000 years, with the help of factors like rising greenhouse gas emissions and climate change.

(mentions the Holocene Maximum, also called the Altithermal, something also not found on Wikipedia)

Another blog 
"The fact that all the world’s complex and expensive climate models can’t explain climate change since the last glacial period ended is one of the little talked about embarrassments of climate science."

Pictures of the Zhangye Danxia Mountains

While Wikipedia does have an entry for the  Zhangye Danxia National Geological Park, there is no picture of how awesome the mountains are.

Dr. Ian Whillans

A climatologist, an important one, with both a subglacial lake in Antarctica and an ice stream in the West Antarctic Ice Sheet, (formerly known as Ice Stream B), named for him.

The warming hole

The warming hole is an area of the United States that has not warmed.


[1] In the last 25 years of the 20th century most major land regions experienced a summer warming trend, but the central U.S. cooled by 0.2–0.8 K. In contrast most climate projections using GCMs show warming for all continental interiors including North America. source
The observed lack of twentieth-century warming in the central United States (CUS), denoted here as the “warming hole,” was examined in 55 simulations driven by external historical forcings and in 19 preindustrial control (unforced) simulations from 18 coupled general circulation models (CGCMs).
