Climate Change: Degrees of Certainty within the Consensus

Of the scientists convinced or confident that climate change is occurring, 48% were convinced that most of the recent or near future climate change is the result of anthropogenic causes; 26% were very confident of this; and 14% were modestly confident.

Climate Change: Exploring the Consensus

...only those authors who self-rated their papers as having an opinion on anthropogenic global warming (AGW) were asked if they personally endorsed AGW themselves.  These authors represented 62.7% of the whole sample - 746 out of 1189 respondents. The authors who self-rated their papers as having no position on AGW were not asked about their opinion on global warming. They were also climate scientists...

Climate Change: Labeling People and Framing the Issues

Doctors need to be willing to act boldly, willing to do nothing, and willing to change their minds. Because the health of the patient is what’s important – not a foolish consistency with past opinions....So it should be when the planet is the patient.

The Puzzle of Orangutans, Part II

Living in the jungle is hard: building nests every evening, extracting the nutritious stuff from thousands of plants. That takes deliberation, reasoning, inference, problem-solving, weighing the pros and the cons.

How Not to Talk to a Climate Change Skeptic, Part VI

...many climate change skeptics don’t contest that the climate is warming.  That’s rarely the issue. More often, the argument is that the relative contribution to warming of human activity/GHG emissions hasn’t been proven to exceed 50%. Or that the pace or extent of warming is not alarming, so does not require extraordinary measures.

How Not to Talk to a Climate Change Skeptic, Part III

Being a skeptic doesn’t mean you don’t care about the environment, wildlife, air quality, or water quality. The idea of being less dependent on fossil fuels is appealing regardless of how you feel about climate change. You don’t have to be worried about global warming to be in favor of reducing the cost of fuel through greater efficiencies.

How Not to Talk to a Climate Change Skeptic, Part II

Parry's right: you're not going to get anywhere with doom-and-gloom scenarios.  Environmentalists have been predicting imminent catastrophe for decades and they’ve been wrong again and again. Skeptics are well aware of this track record of crying wolf while claiming the support of science. 

How Not to Talk to a Climate Change Skeptic, Part I

...hear them out, ask follow-up questions, and avoid knee-jerk rebuttals of their points.  If you want to show respect for a person’s position, you ask them what exactly that position is and how they have arrived at it.

Geoengineering: Part III – Carbon Dioxide Removal

Air capture can remove far more CO2 per acre of land than trees. It also has the potential to pay for itself by producing a commercially viable product – low-carbon fuels – from the recycled CO2.

Geoengineering: Part II – Solar Radiation Management

Others don’t want to move forward with SRM research because they consider it a distraction from what our main focus should be: cutting greenhouse gas emissions. These critics want us to embrace the necessity of sacrifice, not rely on the hope that technology will save the planet before disaster strikes. Such hope would reduce the sense of urgency to act now, so we mustn’t feed that particular wolf.

Geoengineering: Part I

Here we have the themes of impending catastrophe, warfare, and paranoia. Advocates of geoengineering are vilified, their motives suspect. Pragmatic explorations are redefined as ideologies. So what’s the deal?

What Does It Mean To Be a Climate Change Denier, Part VIII

Most of the individuals I’ve focused on have given some thought to this challenge and formulated basic principles on how to approach the possibility of a changing climate: keep energy cheap, reliable and widely available; focus on adaptation rather than mitigation; and, let the market do the heavy lifting. I submit it is these principles rather than “denying” climate change that elicits so much vilification from environmental activists and the progressive community.

What Does It Mean To Be a Climate Change Denier, Part VII

In the past few posts I focused on 11 individuals who have been labeled deniers. As it turns out, only one of these individuals flat-out denies the existence of climate change. The others acknowledge global warming but express uncertainty about the causes, rate, magnitude, or impact of climate change.
