Glaciers Disappearing During NASA’s Coldest Years On record

One of the most popular claims made by climate alarmists is that retreating glaciers are evidence of global warming.

This claim is utter nonsense – glaciers have been retreating for 20,000 years (when Chicago was under a mile of ice) and glaciers were rapidly retreating during NASA’s official coldest years on record.

Roy Spencer on the Unsettled Science of Climate Change: A Primer

“Climate researchers … have a pretty good understanding of how the climate system works on average, but the reasons for small, long-term changes in the climate system are still extremely uncertain.”

“The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small ‘poke’ is very uncertain. The IPCC says there will be strong warming, with cloud changes making the warming worse. I claim there will be weak warming, with cloud changes acting to reduce the influence of that 1% change.”

Global Temperature In 2017: Not A Resurgence Of Global Warming

It is clear that 2017 was a very warm year.

Tomorrow, NOAA, NASA and the UK Met Office will announce by how much.

Global temperature data for the last 12 months refutes the idea that the warmth of 2017 was due to a resurgence of global warming. In fact, the world has been cooling. –David Whitehouse, The GWPF Observatory, 17 January 2018

De Blasio’s Global Warming Lawsuit Is Riddled With Factual Errors

It’s only been about a week since New York City filed suit against five major oil companies, and one economist has already found basic factual errors in the city’s legal filing.

The city’s narrative of a grand conspiracy by fossil fuel companies to silence well-meaning climate scientists has run into reality. One of the climate researchers Mayor Bill de Blasio’s legal team attacked has fired back, pointing out factual errors in the suit.

Science, optimism, and the resilience of polar bears in an ever-changing Arctic

Optimism in conservation science — which the Smithsonian says we desperately need (Earth Optimism Summit 21-23 April 2017, apparently a huge success) — means it’s time to acknowledge and celebrate real conservation success stories.

The Smithsonian folks probably won’t say it but I will — one of those successes is the recovery of polar bears.

It’s time to abandon the focus on prophesies of impending loss and accept that recovery of polar bears from the over-hunting of last century has continued despite a decade of low summer sea ice (Aars et al. 2017; Crockford 2017; Dyck et al. 2017; SWG 2016; York et al. 2016).

Ten easy lessons on climate alarmism

A new lesson set called the Climate Change IQ (CCIQ) provides a good skeptical critique of ten top alarmist claims.

The format is succinct and non-technical. Each alarmist claim is posed as a question, followed by a short skeptical answer, which is highlighted with a single telling graphic.

Then there is a link to a somewhat longer answer, which in turn includes links to a few online sources of more information. Each lesson is also available in a printable PDF version, suitable for classroom use. This compact format is potentially very useful.

Weather events behind late-2015 Arctic warmth, not global warming

Melting sea ice can form puddles on its surface. NASA

CCD Editor’s note: For those that don’t remember, many alarmist news outlets blamed the late-2015 warmth in parts of the Arctic on global warming. They even quoted climatologists who said this had climate change written all over it.

In the winter of 2015/16, something happened that had never before been seen on this scale: at the end of December, temperatures rose above zero degrees Celsius (32°F) for several days in parts of the Arctic.

Temperatures of up to eight degrees were registered north of Svalbard. Temperatures this high have not been recorded in the winter half of the year since the beginning of systematic measurements at the end of the 1970s.

Climate Activists Suffering From Factophobia…Host Of Studies Show No Drought/Forest Fire Trend

Not climate change: forest fires in the USA controlled by El Nino, arson, and land use changes

By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated/edited by P Gosselin)

Droughts increase the risk of forest fires; that’s logical. However, it is false to reflexively assign every forest fire to climate change. There have always been droughts and forest fires. Anyone wishing to shift the blame over to climate change first has to show that the trend has already deviated from the range of natural variability. For many, that is simply too much work.

R.I.P. Greenhouse Gas Theory: 1980-2018

Hansen’s 1988 testimony

Fresh analysis of government scientific records reveals the idea of ‘long-settled’ science in the greenhouse gas theory is a myth. The idea human emissions of carbon dioxide (CO2) acts as a control knob on climate only appeared in consensus science since the 1980s. Prior to that time, official records show the theory as “abandoned.”

Famously, on June 24, 1988, the whole world first heard about the dreaded “greenhouse effect” (GHE) from NASA’s  new champion of the theory, James Hansen. Hansen had breathed life into an old and “abandoned” theory drawing from new space research into Venus and Mars. Thanks to Hansen’s role, climate fear prevailed for a generation.

Bad Weather Is No Reason for Climate Alarm

Two weeks ago, President Donald Trump greeted the cold snap that was gripping much of the U.S. by tweeting, “Perhaps we could use a little bit of that good old Global Warming.” He was criticized for confusing weather with climate. But he’s hardly alone in making this mistake, as we have seen in coverage of the most destructive weather-related events of 2017.

New Study Stomps On Alarmists’ Claims That Global Warming Worsens Winters

The recent cold snap was “highly unusual in the current climate,” and not the product of man-made global warming, a new study found.

But wait, other scientists said the two-weeks of frigid weather and snow in the eastern U.S. was “very much consistent with our expectations of the response of weather dynamics to human-caused climate change.”

Climate skeptics have valid reasons to question man-made warming

Many people are actively worried about global warming. And it frustrates them that skeptics and “deniers” refuse to acknowledge the “science” of such an urgent, man-made problem.

But there may be valid reasons to dispute the theory that man is responsible for climate change. And to demonstrate why the issue isn’t so clearcut here’s a basic climate question to ponder:

As the level of carbon dioxide (CO2) in the atmosphere increases, does its ability to absorb heat increase, decrease, or remain the same?
