Well, this is awkward. Statistics Norway, aka Statistisk sentralbyrå or “the national statistical institute of Norway and the main producer of official statistics”, has just published a paper “To...

It’s remarkable to read that a new study suggests that some, or perhaps most, of any warming that has happened in the last 20 years may have been natural. And it’s remarkable not so much for the...

We bring our Everybody knows series to a close by focusing on the biggest claim of the modern age, namely that climate change is an emergency, crisis, catastrophe or worse. Use your imagination, or...

While the Canadian government imposed our kinder, gentler modern version of martial law over a few rowdy anti-vaccine mandate protesters in Ottawa who stayed too long and broke some minor laws, a...

As the recent kerfuffle over Patrick T. Brown’s mea culpa in getting published in Nature shows, there is a preferred narrative that must be adhered to if you don’t want something nasty to happen to...

All together now: climate change is causing damage from extreme weather to get worse and worse. And don’t say you weren’t warned. As Roger Pielke Jr. notes, the Fourth US National Climate Assessment...

Despite all the clever people declaring that coral reefs were bleaching and dying off due to global warming, the available data shows the picture is not nearly so gloomy. Rather, a new report by...

Climate change is killing off the penguins, by … making too much ice. As in “Antarctica penguins: How too much ice triggered population decline.” Which differs remarkably from the settled science of...

A recent study from the UK (h/t No Tricks Zone) examined data on 10.7 million deaths in England and Wales from 2000 to 2019. They divided the countries up into 1 degree by 1 degree latitude-longitude...

Sea levels are rising all over the world. However, in some places, like Oslo, Norway, the land is rising faster due to glacial isostatic adjustment

Now seems like a good time finally to get to the election of a new head of the UN’s Intergovernmental Panel on Climate Change, the supposedly authoritative and certainly unavoidable IPCC of alarmist...

Continuing our fact check of Al Gore’s rant in Davos we come to his claim that CO2 emissions are causing “the rain bombs”. The what? We hadn’t heard of rain bombs before. Nor is it a term meteorolo...

Yes, cooling. A bit at least. A new study in Nature Communication (h/t NoTricksZone) adds to the evidence that additional CO2 in the air is driving an explosion of greening around the world. Based on...

H/t No Tricks Zone we have learned of a new study led by scientists from Kiel University in Germany that reconstructs temperatures and ice coverage of the North Atlantic off the Labrador coast over...

Call us nerds, or geeks and dorks. But we love nothing more than discovering a new online data source. Here, for the enjoyment of our fellow nerds, is the Colorado State University hurricane records...

We begin 2023 relieved that the unprecedented Southern California flooding of ’22 is now behind us. Witnesses say the flooding was the worst on record: “waters covered the low-lands entirely and rose...

In February 2023 a new study was published measuring what is colloquially called the “greenhouse effect” even though the actual mechanics involved are quite unlike covering a growing space with a...

Every time you hear the claim that this or that year is the “warmest in a thousand years” (or ten thousand or eleventy bazillion) please remember that we have no thermometer records for most of the...

In the upside-down world of climate science, where every bad thing is caused by climate change and there is a voracious need for weather disasters to prove just how bad things are getting, nothing...

From the CO2Science Archive: Climate alarmists have long worked to convince the world that late 20th-century temperatures were unprecedented over the past one to two millennia, attempting to discre...

We previously reported on two studies showing that after the end of the last ice age about 11,000 years ago, the Arctic on both the Russian and Canadian sides warmed rapidly to a level much warmer...

The 97 Percent Consensus Myth Revisited Transcript John Robson: For the Climate Discussion Nexus I’m John Robson, here to present you with an update of one of our very first videos, on the most...

To prove the horrors of man-made warming, or for the exquisitely woke human-made though perhaps women prefer not to get blamed, two groups of committed climate researchers set out to traverse the...

As a reminder of what we went north in search of, here’s is how the Government of Canada represents the changing winter climate of the far north: We had hoped that for our final stop on the sunburnt...

One luxury climate alarmists enjoy is that they can say anything and people will assume it’s true. Announce that wildfires are increasing globally and no one will question it. Declare that sea level...

Everybody knows, or once knew, about the poor little rich kid whose family’s affluence spoiled them despite their parents’ best efforts. But what about an entire society? It’s a question Jude...

Among climate alarmists, to our mingled relief and amusement, reality is starting to set in. A quarter-century ago, they could rant, rave and visualize all they wanted about the coming apocalypse in...

From the CO2Science Archive: The author notes that “media reports in recent years have left the public with the distinct impression that global warming has resulted, and continues to result, in...

“IFAR” isn’t a typo. It’s a tool used by climate scientists (or scientivists as they are sometimes called, merging “scientist” with “activist” in name as so many do in practice) to measure the costs...

Greenland, that wretched mass of ice, keeps drowning us all. When will it stop? Not any time soon, apparently, as the glacier cap is melting faster than the settled science predicted, as usual, and...

Canada’s Department of Natural Resources is worried that “communities across Canada face the consequences of more frequent and more severe floods and wind storms, heavier snow loads and longer,...

There’s an unwritten rule in climate change reporting that you can point to any bad weather and claim it’s getting worse without bothering to cite any data. A frequent choice in this regard is...

As in, rip-roaring, or at least coming back as it always does, and lately faster than expected. Ron Clutz’s Science Matters website shows satellite-based measurements of the September minimum sea ice...

We also note grumpily that while we were away another scare story went extinct without our assistance. The Great Barrier Reef, due to be laid to rest next to emaciated polar bears, the charred...

Australia’s ABC made a big deal out of hot weather in summer, which of course it now is south of the equator, predicting grassfires and heat-related illness during the Christmas break. But an alert...

In 2015 the BBC ran a program called “Climate Change by the Numbers”, in which they picked three numbers they thought were representative of the climate change issue and handed them to three profes...

In two months, Zuckerberg's CO2 footprint was 15x larger than the average American's annual carbon footprint.

Courtesy of Kenneth Richard of No Tricks Zone we learn of a new study in the Journal of Climate measuring the warming of Greenland. Or rather lack of it, at least after 1994. The authors compiled all...

The milder weather across southern Alberta will turn much colder this weekend, then Arctic air will plunge south into the region again for next week with a couple days of "severe cold" expected.

Periodically it is helpful to step back from the details and ask what it’s all about. Thus sometimes we give our heads a bit of a weary shake and say it doesn’t matter how cleverly you explain why...

If you’re looking for a real climate crisis, forget Sharm el-Sheik and look at the damage climate change policy is doing to real people. For instance “Brits are paying the highest electricity bills...

One of our complaints about global warming alarmism here at CDN is that unlike normal science, climate science rarely puts forward testable predictions ahead of time against which we can measure the...

In February and March of 2022 we ran a series summarizing a scientific paper by a team of Italian scientists led by Gianluca Alimonti presenting a review of data on extreme weather. The paper found...

The CBC, Canada’s state broadcaster ran a glowing self-profile by a guy who “got a vasectomy due to climate grief”. A failing media company with a collapsing audience share going through Christmas...

Last week we highlighted Roger Pielke Jr’s discovery of the IPCC's false claim that tropical cyclones are becoming more intense, which Pielke now reveals a “high level participant” in the IPCC...

Just kidding. Sure they can. In fact they can be worse than wrong, they can be completely misleading. According to a literature review by American climate scientist Roger Pielke Jr., nearly 17,000...

From the CO2Science Archive: The authors of this unique study compared “the physiological (stomatal-regulation) and modeled-growth responses of glacial and modern Juniperus trees at La Brea by using...

A new paper by Italian climate scientist Nicola Scaffeta published in GeoScience Frontiers has reopened the whole discussion about the sun’s role in climate change. Or perhaps we should say has kept...

It might seem like a fool’s errand to fact check Al Gore. But the man does have a big audience and someone’s got to do it so we rush in. For the next few weeks we are going to entertain ourselves,...

A new study by an international team of scientists (h/t No Tricks Zone) gathered detailed daily sea level measurements at three locations along the coast of Peru where the rapid sea level increases...

Something called “The i”, which is “a British national newspaper published in London by Daily Mail and General Trust” whose marketing department is apparently desperate to seem hip, bellows that...

This week we look at part 3 of Bjorn Lomborg’s massive 2020 study of everything known, believed, hypothesized, guessed and outright made up regarding how climate change will affect the world in the...

One of the fudge factors in climate modeling is the amount of cooling that happens from “aerosols,” aka microscopic pollution particles, in the air. If you insist that greenhouse gases have a...

Does anyone even remember the “Precautionary Principle”? It used to be big among environmentalists back when they could use it to spike anything they didn’t like. Not that anyone could actually...

The growing disconnect between climate alarmist rhetoric and real people’s experience seems to be leading to a doubling down rather than a rethinking. Judith Curry scoffed “Wow, ‘global boiling’ is...

This week we begin a detailed look at the new report from Clintel.org, a Netherlands-based group, entitled The Frozen Climate Views of the IPCC. The report examines several prominent claims of the...

“Rising sea levels are threatening this Pacific paradise” warned CNN in 2019. Two years later Tuvalu foreign minister became an internet sensation by addressing the UN COP26 summit while knee-deep in...

Courtesy of Tony Heller we want to pass along a very good way not to start a conversation at COP28 or whatever cool climate gab-fest you’re planning to attend in the near future. It’s safe enough to...

One revealing recurring thing about climate alarmism is their obsession with making us eat bugs. It can’t be helping them win friends and influence people even if they insist that insects are...

If the continental United States had on Nov. 1 been on average 11°F warmer than normal, or even if on Halloween North Dakota alone had been 44°F warmer, the usual suspects would have no difficulty...

From the CO2Science archive: Enough serious work has been conducted on the growing, harvesting and processing of the raw materials that can be transformed into biofuels to indicate that they are...

On climate, as on many contemporary policy issues, there is a tendency for people on both sides to dig in, jump on events or arguments that seem to confirm their approach, while stomping on those...

Despite a long history of climate policies costing far more than planned and accomplishing precisely nothing, the option of making a principled and logical decision to do no harm seems beyond the...

Continuing with our fact check of Al Gore’s rant in Davos we come to his claim that you-know-what is “creating these atmospheric rivers”. And “atmospheric rivers” is, admittedly, a very impressive...

In honour of a scientific journal retracting an article not because it was wrong but because the alarmist gatekeepers don’t want you to read it, we are re-running our series telling you what the...

An alert viewer asks “How long does a wind turbine or solar panel have to run before it makes up for the energy and emissions just to produce it?” To which we confidently shrug and say “Anybody’s...

For a few minutes last week it sounded like a future of free, unlimited clean energy was upon us, when scientists at Lawrence Livermore National Lab announced something or other to do with fusion,...

There are some things that need to be repeated over and over again in the climate debate, including one that also has to be repeated over and over again in economic debates: If something needs a...

Climate scientist Patrick T. Brown wrote a thread on Twitter discussing claims in the New York Times that climate change is making hurricanes more intense. Brown is, unusually for climate scientists...

Five commonly used words around Energy and Climate that are both deceptive and destructive: climate crisis, energy transition, carbon pollution, clean energy...

This one will take us more than a week to go through, because it’s a whole website full of cool climate data. Climate4you.com is a project of Ole Humlum, Emeritus Professor of Physical Geography at...

Speaking of demonstration projects, how about that climate researcher from the Kiel Institute for the World Economy who refused to fly back from Papua New Guinea to Germany because of the carbon...

Note: this post has been edited to correct an earlier version. Continuing with our fact check on Al Gore’s epic rant in Davos, this week we turn to his claim that, referring to CO2 emissions, “That’s...

From Joanne Nova in Perth, Australia, we learn that only 3 percent of Australians believe that the Great Barrier Reef has attained record high coral cover. And according to the iron rule of climate...

From the CO2Science Archive: Background: The authors state at the outset of their provocative new paper that “we know [our italics] that there are terrestrial imprints of the solar cycle,” even when...

After years of laments about the lack of snowpack in the American west due to global heating we now hear from Scientific American that “The West Braces for the Most Epic Snowmelt in 40 Years”. And...

Reuters “Sustainable Switch” emails that “Activists ramp up protests against fossil fuels”. How do they know? Who counts the number, size and intensity of protests worldwide and determines that they...

The big story is, supposedly, COP28 gathering to bicker and waste time as a stirring prelude to COP29. But what’s this? The New York Times “Climate Forward” whimpers that “It’s no secret that fossil...

Back when hurricanes were a thing they were blamed on climate change. Then there was a long pause and it was blamed on climate change. Then there were more and, well, you know. Just as, we pointed...

One of many recurring puzzles on the climate file is the growing hostility of environmentalists to nature. For instance (h/t Patrick Moore) Bill Gates is helping fund a scheme to bury trees to keep...
