Good Arguments and Bad Arguments About Climate Change

Featured image Roy Spencer, who was a senior scientist for climate studies at NASA for many years, author of The Great Global Warming Blunder, and one of the inventors of the satellites that now track global temperature data, has two very useful posts up at his website on bad and good arguments about climate change.  Being a scrupulous scientist, he is concerned when he hears critics with the right inclinations push bad »

Conservatives and Climate Policy

Featured image Not long ago the journal Issues in Science and Technology (a consortium publication of the National Academy of Sciences, Arizona State, and three other institutions) challenged me to write a piece about “Conservatism and Climate Science,” and the long piece is just now available online.  But it’s really not about climate science, but rather climate policy, and the heart of the article is a lengthy consideration of the problem of »

Earth Week Leftovers

Featured image Earth Day came and went without much real fanfare earlier this week (my environmental policy students mostly yawned when I brought it up), so it’s almost hard to recall that for a while back in the late 1990s the Green Weenies tried for a time to make Earth Day into Earth Week: Earthpalooza!  Erathonaroo!  Or something. There are a few loose ends of this this week’s scant observances worthy of »

Why Are Extreme Weather Events Becoming Less Common?

Featured image The Earth’s climate is poorly understood, and random variation likely accounts for most of the ups and downs of notable weather events. But for some reason, extreme weather events are becoming less common. The United States has now gone longer without a landfall of a Category 3 hurricane than at any time in recorded history. And something similar is happening with tornadoes. Tornado frequency is at the lowest level in »

This Week’s Climate News

Featured image A month into Spring, and whaddyaknow: the Great Lakes are still 37 percent frozen over—the second highest level since precise satellite measurements began in 1973.  NOAA posted this satellite photo a couple days ago: And Environment Canada offers this bar chart of ice levels as of this date for every year back to 1980: But who knows: maybe this will front-fire for the Climatistas.  As Clive Crook argues cogently at »

On Evaporation, the Scientific Battle Rages

Featured image Since they lose pretty much every argument, the global warming fraudsters try to tell us that the science is settled, and we should all just shut up. In fact, however, debates over various aspects of climate science are constantly raging. This one is a great example: “Major Errors Apparent in Climate Model Evaporation Estimates.” But first, let’s set the stage. It is generally accepted that ceteris paribus, increasing the concentration »

The Declining Utility of Scaremongering

Featured image Back in 2005 New York Times‘ moderately liberal columnist Nicholas Kristof offered his his criticism of today’s environmental movement in “I Have a Nightmare.”  Excerpt: The fundamental problem, as I see it, is that environmental groups are too often alarmists. They have an awful track record, so they’ve lost credibility with the public. Some do great work, but others can be the left’s equivalents of the neocons: brimming with moral »

The Obama Administration Lies About Hurricanes

Featured image Whether human activity significantly influences the Earth’s climate is a matter of opinion, but it is a simple, undeniable fact that there has been no increase in extreme weather events, either globally or in the U.S., in recent years. Even the IPCC, the U.N.’s corps of true climate change believers, admits that this is true. Hurricanes, for example, have been counted, tracked and measured for many years. There has been »

Global Warming Hysteria: A Retrospective

Featured image At the Telegraph, Christopher Booker provides a succinct narrative of the rise and fall of global warming alarmism: When future generations come to look back on the alarm over global warming that seized the world towards the end of the 20th century, much will puzzle them as to how such a scare could have arisen. They will wonder why there was such a panic over a 0.4 per cent rise »

Lying About Global Warming: It’s a Good Thing!

Featured image Various warmists have let the cat out of the bag over the years, acknowledging that they exaggerate the danger of global warming for the sake of the greater good. But for the first time, two scientists have published a peer-reviewed paper in an academic journal, advocating lying about global warming. The scientists are Fuhai Hong and Xiaojian Zhao, the publication is the American Journal of Agricultural Economics. The full article »

Al Gore: The Gift That Keeps on Giving

Featured image No sooner does Bill McKibben come up with a great idea (climate scientists should go on strike) than I hear even better news: Al Gore is thinking about making a sequel to An Inconvenient Truth.  From the Hollywood Reporter: Al Gore might need to dust off his projector. The creative forces behind the Oscar-winning environmental documentary An Inconvenient Truth are hatching plans for a sequel to the film that raised »

Climate Scientists Go on Strike? Oh Please Make It So!

Featured image I’ve written before here about the crashing bore that is Bill McKibben–the best exemplar of Churchill’s definition of a fanatic as someone who can’t change his mind and won’t change the subject.  But he deserves kudos for today’s toddler-like temper tantrum over at,  fittingly, MSNBC.com.  He’s suggesting that since politicians, including John Kerry, won’t listen to the climate science community, then climate scientists should go on strike. So at this »

First World Problems in Boulder

Featured image As previously mentioned, the IPCC released it’s “impacts” report today, and the media did their duty by collectively wetting their pants.  You think I jest?  Check out—if you can stand it—NBC’s Brian Williams saying that “We’ve never been warned like this before” about climate change.  Really?  What 30 Rock has he been living under?  (Next he’ll tell us that nobody has ever warned us before about the dangers of cigarette »

When Did Anthropogenic Global Warming Begin?

Featured image If you read pretty much any climate alarmist literature, you will see the claim that the Earth’s warming over the last 100 years is due overwhelmingly to the burning of fossil fuels. But this is disingenuous: even under the defective models on which the alarmists rely, it cannot be claimed that prior to 1950, human contributions of CO2 to the atmosphere could have had any significant effect. So why do »

Global Warming? What Global Warming?

Featured image Steve is, I believe, cloistered as he plows through the IPCC’s latest report on the baleful consequences of “climate change.” Meanwhile, alarmist headlines are everywhere. But more sophisticated observers are asking, global warming? What global warming? At Watts Up With That, Christopher Moncton adds the just-reported HadCRUT4 numbers to the dataset of datasets, which shows zero warming this millennium: We are, of course, living in a relatively cool era. Global »

“I Can See Climate Change From My House”

Featured image The “impacts” report of the IPCC is out today, and we’ll try to get through some of the highlights of the thousand-page plus report.  (Always reminds me of Churchill’s note about an overlong memo: “This report, by its very length, defends itself against the risk of being read.”  We’ll take the risk.)  Turns out that an acquaintance of mine helped write the FAQ portion of the report. But we don’t »

Climatistas Double Down on Stupid

Featured image When a liberal says it’s time for you to shut up, it usually means they’re losing an argument.  When they want you arrested and prosecuted, well. . .  Two weeks ago I noted here that the climatistas were getting so desperate that they were starting to call for climate skeptics to be arrested and prosecuted, because, like the Inquisition, the climatistas are in possession of the complete truth, so shut »
