John Holdren, Barack Obama’ senior advisor on science and technology has been frequently quoted as saying:
We basically have three choices: mitigation, adaptation and suffering. We’re going to do some of each. The question is what the mix is going…
Participating in social media creates a wide and diverse network of acquaintances. Often, these people become “friends”, even though direct personal contact may never made with them. It can be hard to establish traditional friendships without face-to-face encounters. Before the…
According to NASA, July 2017 was the warmest July on record, just slightly higher than July 2016. The global average anomaly was 0.83° C.
The year-to-date average anomaly is 0.94° C.
(Oops, the x-axis label is wrong. It should read…
I update the GISTEMP records every month, but I missed writing up April’s monthly summary. Real-world events have set my priorities elsewhere and this May 2017 write-up is a couple of weeks overdue. Monthly updates are probably overkill anyway, especially…

The 97% consensus on anthropogenic global warming (AGW) reported by Cook et al. (2013) (C13) is a robust estimate. Alternative methods, such as James Powell’s, that identify only explicit rejections of AGW and assume that all…
This is a quick update to my temperature graphs based on the latest NASA GISTEMP numbers. First, the monthly anomalies.
The March anomaly was 1.12C, the second-warmest March and the fourth-warmest month ever. In the absence of an El Niño,…
A bungled correction to a Globe and Mail article reveals that the intent was to publish a puff piece on the oil sands, not an objective analysis of the future of bitumen production in the face of serious climate change…
NASA’s GISTEMP temperature estimates for February 2017 are now out. February 2017 was the second-warmest February since records began (the first-warmest being in 2016) and was tied for the fourth-warmest monthly anomaly for any month.
Here is a plot of…
If the world is successful in reducing emissions sufficiently to avoid dangerous climate change, there is a limited future for a prospering oil-sands sector in Canada. The conventional wisdom among the Canadian establishment is that growing the oil-sands business is…
A graph that I included in my last monthly surface temperature blog post attracted a lot of attention thanks to a Tweet by Eric Holthaus.
Nearly 4,000 retweets is a lot of attention for a blogger like me. The graph…
