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.

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.

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.

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.

It's bad enough for visiting mountaineers, but so much worse for people whose lives depend upon glacier-fed streams.

I’ve worked in this field because I believe it’s one of the solutions to climate change. Creating clean energy doesn’t mean destruction and degradation of the environment and creating huge amounts of greenhouse gases. It means leaving a slight footprint with minimal negative impacts. It provides community pride and diversification of the economy, as well as revenue, jobs and capacity building.

Being awarded the Order of Canada for this work that I have a passion for, fought for, and been part of, a worthwhile industry where I am respected, means so much. Clean energy must be at the forefront in the fight against global warming, and if being part of the Order of Canada helps elevate clean energy, then I think it’s important to participate.

Volkswagen’s electric car sets Pikes Peak record

Two-time Le Mans champion Romain Dumas took the green flag in his specially prepared Volkswagen I.D. R prototype racer, and a scorching seven minutes 57 seconds later, crossed the finish line and entered the record books as the fastest car to ever ascend Pikes Peak. For the first time in more than a century, an electric car had beaten all comers and shattered the record.

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.

This book is about why we have ignored those warnings,
  so that now it is too late.
It is a book about the frailties of the human species:
  our strange obsessions, our hubris, and our penchant for avoiding the facts.
It is the story of a battle within us between
  the forces that should have caused us to protect the earth, like our capacity to reason and our connection to nature,
  and our greed, materialism and alienation from nature, which, in the end, have won out.

In the age of neoliberal capitalism, everyone in authority who is concerned about global warming seems to agree that the solution to the problem is to put a price on the emissions produced by the burning of fossil fuels but not to restrain the global corporations from expanding their search for ever more coal, oil and gas. An intelligent and observant Martian visiting the Earth and learning of our climate problem would be entitled to believe the human race insane.
