Let’s call it: 30 years of above average temperatures means the climate has changed

If you’re younger than 30, you’ve never experienced a month in which the average surface temperature of the Earth was below average.

Each month, the US National Climatic Data Center calculates Earth’s average surface temperature using temperature measurements that cover the Earth’s surface. Then, another average is calculated for each month of the year...

Nell, Dudley and Snidely: Uncertainty

In last week’s article I wrote:

Probability and likelihood are notoriously difficult ways to communicate in quiet consultation, and even more difficult in newspapers, on the radio, television and online. Probability and risk are just made for conflicting headlines. The conclusions are, therefore, by definition, uncertain, and uncertainty can always fuel both sides of a rhetorical or a political argument...

My comment was that I didn’t think the storm should be conflated with climate change, and I had doubts about it being “historic.” This, of...

Changing the Headlines: Riffing on Revkin

I want to revisit the strategies of communication that we use when writing and talking about climate change.

Not Writing About How Hot 2014 Was:

I will be the only climate-change blogger not writing about how hot it was in 2014. Nor will I write about how remarkable this fact might be because there was not an El Niño. I want all of my faithful blog readers to go back to my entry from May 29, 2014, and then paste into comments on other people blogs “We have remained warm, globally, despite relatively cool temperatures in the eastern Pacific. Given the impo...
