7:12 PM | Men’s Wrongs
I am disgusted, because I just read this. Here’s a brief excerpt: Stefan Molyneux, a Canadian radio host, blamed mothers for the violent behavior of men. Molyneux said that because 90% of a child’s brain is formed by the experiences … Continue reading →

5:35 PM | Uncertainties in the timing of unprecedented climates
Back in October 2013, Nature published an analysis by Camilo Mora et al. which discussed when ‘unprecedented climates’ would emerge, with a focus on regions of high biodiversity. The paper was highlighted by Nature with an associated News & Views … Continue reading →

1:55 PM | Unforced variations: July 2014
This month’s open thread. Topics of potential interest: The successful OCO-2 launch, continuing likelihood of an El Niño event this fall, predictions of the September Arctic sea ice minimum, Antarctic sea ice excursions, stochastic elements in climate models etc. Just for a change, no discussion of mitigation efforts please!

5:33 AM | 'Reform conservatism' is not enough reform on global warming
The conservative YG Network recently published a series of ‘reform conservative’ essays called ‘Room to Grow,’ designed to create a ‘thriving middle class’ while limiting the size of government. Those essays have been subject to intense criticism from Vox’s Matt Yglesias and New York Magazine’s Jonathan Chait for failing to even mention climate change despite devoting a chapter to energy policies. Adam White, author of that energy policy chapter, […]

2:05 AM | How much surface area can you fit in a space the size of an ice cube? Several football fields in a new battery cathode!
If any of us ever hope to complete the romantic cross-country trip across the US by electric car, the answer lies in better battery technology.  Current batteries just can’t store enough energy to last trips without frequent stops to recharging stations. … Continue reading →

11:37 PM | TDB Today: Getting out the climate vote
In this week’s article at The Daily Blog — Getting Out The Climate Vote — I take a look at the first batch of responses to the Climate Voter question of the week: President Obama calls climate change one of the most significant challenges we face, requiring urgent action by all governments. Do you agree?. […]

4:18 PM | Mercury Rising: 2014 Sees Warmest May Ever Recorded Following on From 2nd Warmest April
Increasing greenhouse gases in the atmosphere, from human industrial activity, are trapping ever more heat in the atmosphere and ocean. This is causing the Earth to warm regardless of a downturn in solar radiation over the last 3-4 decades. Despite this long-term warming of the background climate state, especially the warming of the ocean, global surface temperatures exhibit fluctuations from year-to-year because the Earth's weather is never the same in each year. Figure 1 - global […]

10:10 AM | Record winter warmth in NZ: June 2014 breaks 140 year record
Hot off the press — or to be precise, Jim Salinger’s laptop: June 2014 was the warmest June in New Zealand since 1870, 2ºC above the 1971-2000 average, as measured by the long term “seven stations series” originally devised by Salinger and maintained by NIWA. On the larger 24 station series the month tied with […]

8:00 AM | The signal, the noise & the time of emergence
Temperatures have increased over most parts of the planet, but this signal is somewhat obscured by the random noisy fluctuations of natural climate variability. The year in which we can we detect the ‘signal’ of temperature change in the presence … Continue reading →

8:19 PM | Stuck in the Pleistocene: The science of the La Brea tarpits
As a scientist, there are places I want to visit one day because they feature heavily into the intellectual mythology of my field: Darwin’s Down House, Mount Chimborazo, the Galapagos. At the top of the list, my scientific Mecca has been the fossil-rich Pleistocene tar pits at Rancho La Brea. […]

5:23 AM | Global warming makes drought come on earlier, faster, and harder
We all know that some climate change is natural, in fact, even without humans, the Earth’s climate changes. But, as we have added heat-trapping gases to the atmosphere, we have seen human influence “emerge” from natural variability. Droughts, one of the most intensely studied climate events, are a perfect example of an effect with both human and natural influences. Separating the relative strengths of the influences is a challenge for scientists. But, when we deal with […]

This guest post is by professor Peter Barrett, executive producer, and Suze Keith, marketing advisor for Thin Ice. Scientists can tell human stories about climate change, and a group of us have been working on just that for the last few years. We’ve produced a film — Thin Ice – the inside story of climate […]

6:03 AM | Shrinking dairy’s carbon hoofprint
As the world’s appetite for dairy produce grows along with its population so too will emissions of the greenhouse gas methane from cow guts – but US dairy industry consultant Joanne Knapp and her team have found that measures including more intensive farming and ensuring healthy herds can offset a lot of this.

5:55 PM | Who Founded Greenpeace? Not Patrick Moore.
In what seems to me to be an indisputable refutation of an oft-repeated claim, ScienceBlogs has shown that any claim by Patrick Moore that he founded GreenPeace, or was a co-founder, is false. Of particular note is a letter written … Continue reading →

8:49 AM | Self-review of problems with the HOME validation study for homogenization methods
In my last post, I argued that post-publication review is no substitute for pre-publication review, but it could be a nice addition. This post is a post-publication self-review, a review of our paper on the validation of statistical homogenization methods, also called benchmarking when it is a community effort. Since writing this benchmarking article we have understood the problem better and have found some weaknesses. I have explained these problems on conferences, but for the people that did […]

5:55 AM | Summer reading for the climate crowd
This is a re-post from The Daily Climate by Douglas Fischer Drop the Thomas Piketty. Let's all admit right now you weren't going to read that 696-page economics tome anyway.  And set aside Donna Tart's "Goldfinch," too. Yes, it's beautiful. Yes, it won the Pulitzer. Yes, it's 775 pages. It's summer, people. Time for a little skin. A bit of fun. Something light and insouciant. Time, in short, for The Daily Climate's annual summer reading list. Real blockbusters Before we get to books, […]

12:29 PM | Open post-publication review is no substitute for pre-publication review
We have submitted a new paper. It describes how we are planning to validate the performance of homogenization methods that remove non-climatic effects from station climate data. The way scientists write, the paper neutrally describes the new plans. For people that know the relevant scientific literature that is naturally also a critique of how we did it before, for them there is no need to spell this out and rub salt in the wounds. However, people that do not know the literature may get the […]

5:08 AM | New Skeptical Science study finds physics trumps economics, suggests global warming is man-made
A new paper by several Skeptical Science contributors (Richardson et al., 2014) in Quaternary International points out that a previous study (Chen et al., 2013) made mistakes in using economics techniques to calculate how much recent global warming is man-made. Most climate science studies, such as the 8 examples here and Stone et al. (2005), Stott et al. (2011), Hegerl et al. (2011), Santer et al. (2013) and Ribes and Terray (2013), conclude that man-made […]
