"Do as I say, not as I do" is always good for a laugh.
Experts have predicted up to 1,500 individual private jets flights will be made in and out of this year’s Davos summit, despite hosting a series of talks on the dangers of man-made climate change.
The World Economic Forum (WEF)’s annual meeting of global leaders is taking place in the Swiss resort town this week, with David Attenborough attending to offer a stark assessment of global warming trends.
But the Air Charter Service (ACS), a company arranging flights around the world, has estimated there could be a record number of carbon-emitting private jet flights in and out of Davos for the duration of the event.
The previous high was recorded at the 2018 summit.

^^^ That’s nothing compared to the large jet traffic occassioned by the really big global warming conferences held all over the world all the time where 10x as many people show up to hand wring and party up a storm. Oh, and come up with new regulations to ensure their job security.

^^^ That's nothing compared to the hot air blown by 10000X as many deniers who propose no solution since their thought process does not extend beyond blaming the problem on someone else.

And instead of whining about the jet travel of people who are concerned about climate change, we need a carbon tax to actually change people's behavior.

https://www.accuweather.com/en/weather-news/polar-vortex-by-the-numbers-6-states-in-us-record-temperatures-lower-than-south-pole/70007296
Records have been shattered as the polar vortex unleashed the harshest cold in years on the midwestern United States during the final days of January.
After the polar vortex plunged southward, temperatures plummeted under 20 below zero F from North Dakota to northern Illinois during the morning hours of both Wednesday and Thursday.
The low of 38 below zero recorded at Mt. Carroll, Illinois, is being reviewed by a state climate extremes committee to determine if the Illinois state record low was broken on Thursday morning. The current record is 36 below zero that was set near Congerville on Jan. 5, 1999.

Australia recorded its hottest month ever in January
https://www.bbc.com/news/world-australia-47085785
Australia recorded its hottest month ever in January, with average temperatures exceeding 30C (86F) for the first time.
According to the Bureau of Meteorology, the extreme heat was "unprecedented" during the country's summer period.
At least five January days were among the 10 warmest on record, with daily national temperature highs of 40C.
The heat has caused wildfire deaths, bushfires and a rise in hospital admissions.

It's an interesting item, I'd like to delve into the details that support their assessment of the number of people who were exterminated and died from disease and displacement, and the research that would support that amount of reforestation. It's seemingly plausible, but one likes to read the background supporting stuff.
Flipping it around the other way, the mind-boggling amount of forest removal at the present time is not only a lot of greenhouse gas source, but also removal of a very large sink. We're kind of toast, literally, without some response pretty darn soon. It's certainly true a lot of tropical forest could be reestablished, but the economics and population pressures and will to do that make it extremely unlikely on the timeline that is needed.

You can go to the original article, which was published in Quarternary Science Reviews, a peer-reviewed journal, from the CNN article. It is a very fascinating article. In terms of the commonperson's understanding of the effect of human activity on the climate, I find this to be even more alarming than other observations.

European colonizers killed so many Native Americans that it changed the global climate, researchers say
"For once, we've been able to balance all the boxes and realize that the only way the Little Ice Age was so intense is ... because of the genocide of millions of people,"
A small shift in temperatures -- about a 10th of a degree in the 17th century -- led to colder winters, frosty summers and failing harvests, Koch said.
My college anthropology professor taught our class that diseases introduced by the Europeans to the Native Americans killed as many as 100 million Native Americans and that was the cause of the little ice age, he taught that over 35 years ago. It made sense to me then, and that was long before almost anybody was aware of the concept of global warming.
When the earliest Dutch and Portuguese explorers traveled along the North Atlantic coast of the USA in the 1500's they were often afraid to come ashore because of the many warlike tribes of Native Americans that populated these lands, they weren't welcomed. By the time the Pilgrims arrived in the early 1600's lands were mostly empty with in many cases 80% of the local Native Americans having died from disease.

The theory of climate change has been around a lot longer than 35 years (contrary to what some oil companies would want you to believe). From Wikipedia:
However, in 1899 Thomas Chrowder Chamberlin developed at length the idea that changes in climate could result from changes in the concentration of atmospheric carbon dioxide.[12]
In 1967, taking advantage of the ability of digital computers to integrate absorption curves numerically, Syukuro Manabe and Richard Wetherald made the first detailed calculation of the greenhouse effect incorporating convection (the "Manabe-Wetherald one-dimensional radiative-convective model").[13][14] They found that, in the absence of unknown feedbacks such as changes in clouds, a doubling of carbon dioxide from the current level would result in approximately 2 °C increase in global temperature.

Thanks all for the interesting posts. The way I learned it, it was Arrhenius who was the first to publish the concept that CO2 emissions would cause an increase in global temperatures. And indeed this appears to be the case: his papers on it are dated 1896, a hair earlier than the 1899 cited just above. He was an amazing scientist all around, well deserving of the Nobel Prize. Props to everyone who has contributed to advancing climate science then and now.

Yes because if we admit the problem then we admit that possibly, maybe we sort of need to do something about it.
Much safer to attack and denigrate any politician trying to start a conversation on it.
