About

Human activity, such as the burning of fossil fuels to power our homes and businesses and changes to the land caused by the rise of modern cities and expanded agriculture, undoubtedly affect the global environment. It is the extent of that effect and how it relates to changes in the modern climate which is the subject of current scientific debate.

Wise, effective climate policy flows from a sound scientific foundation and a clear understanding of what science does and does not tell us about human influence and about courses of action to manage risk. Many of the temperature data and computer models used to predict climate change are themselves as uncertain as are our understanding of important interactions in the natural climate.

Are calls about the uncertainty in the state of scientific knowledge a call for no action? Nothing could be further from the truth. The message to policy makers is not to delay actions until uncertainties are reduced. Rather, actions should flow from the state of knowledge, should be related to a long-term strategy and objectives and should be capable of being adjusted- one way or the other- as the understanding of human influences improves. There is a sufficient basis for action because the climate change risk is real. Yet it is equally true that actions must not be predicated on speculative images of an apocalyptic vision of life in the near future.

Wikipedia Page on Propaganda Techniques Uses 97% Meme

If 99 billion mouths agree, shouldn’t you? Oh, this is too rich. I’ve blogged before on how global warming alarmists use all of the standard propaganda techniques to convince the not very super-sophisticated masses, using Al Gore’s own words. Well, it turns out the “97% of all scientists agree” meme is being used as an […]

The Magic of Models

A study recently published in the journal Nature Climate Change has gained a lot of attention in the environmental community and mainstream media—National Geographic for example. According to the study, the Keystone XL pipeline could produce four times more greenhouse gases than the State Department estimated in its final review in January. Since the study […]

Climate Polling Results Lead to Weird Press Coverage

A recent polling of Americans on their attitudes about how much scientists know (or claim to know) about global warming, as well as what should be done about it, has led to very different treatments in the press, specifically in the Pittsburgh Post-Gazette, which commissioned the poll. The PG’s editorial take on the poll is […]

Son of Kyoto

The MIT analysis should be a sobering message to the climate change cultists. The Global Change Program at MIT is first rate and is comprised of serious scholars. Jake Jacoby is a well regarded economist and the study conducted by him and his colleague is rich in significance. It is unfortunate, however, that the study […]

Claim: study published in Nature shows that small variations in the climate system can result in dramatic temperature changes

“There are apparently some situations in which the climate system is more resistant to change while in others the system tends toward strong fluctuations,” summarises Gerrit Lohmann. “In terms of the Earth’s history, we are currently in one of the climate system’s more stable phases. The preconditions which gave rise to rapid temperature changes during the last ice age do not exist today. But this does not mean that sudden climate changes can be excluded in the future.”

The Sun In July 2014 And Arctic Sea Ice In Mid Summer

Every summer over the past years Arctic sea ice has been the subject of much public interest. Especially after 2006 there have been years (recall 2007 and 2012) when a large part of the Arctic ice cap melted away and all the talk was about the “Arctic death spiral“.

The Kardashians and Climate Change: Interview with Judith Curry

Climate change continues to drive energy policy, despite the fact that there is no way to reconcile eradicating energy poverty in much of the world with reducing carbon dioxide emissions. This is one of the many conundrums of the climate change debate—a debate that has been taken over by social media and propaganda, while scientists struggle to get back into the game and engage the public.
