In collaboration with The University of Queensland, Skeptical Science is developing a MOOC, or Massive Online Open Course, that makes sense of climate science denial. The Denial101x MOOC will launch in March 2015 on the EdX platform. Registration has just opened so you can now register for free. Here is a description of the MOOC:   Denial101x: Making Sense of Climate Science Denial Climate change is real, so why the controversy and debate? Learn to make sense of the science […]
11:16 PM | Things you can do about global warming now we have a new do-nothing government (same as the old one)
Australia’s brilliant First Dog On The Moon on climate action (courtesy of The Tree), deemed by me to be relevant in the aftermath of an election that has delivered New Zealand another three years of National-led government, and therefore little prospect of serious action on climate matters. I’ll have a slightly less amusing reaction to […]

5:52 PM | Solving the metal problem: new polymer used in organic solar cells to allow wide use of metal cathodes, improve efficiency
Organic solar cells (OSC) are an exciting next-generation option for photovoltaics.  The main advantage is that they’re cheap, easily processed using solution-based methods, which opens up many innovative applications – printable cells, even solar paint! The main issue holding OSCs back is … Continue reading →

7:36 AM | 50 Canadian climate researchers speak out in support of the People's Climate March
The Canadian government is hell-bent on exploiting the Alberta tar sands to the fullest extent possible, even at the expense of the global climate. Canada simply cannot meet its carbon pollution reduction pledges if it continues to expand tar sands operations. While the American government has finally begun to take the threat of climate change seriously and do something about it, the Canadian government has merely played lip service to the problem. 50 Canadian climate researchers have reached […]

5:56 AM | The Perplexing PETM
The Paleocene-Eocene Thermal Maximum (PETM) around 56 million years ago is perhaps the most studied of the many episodes of global warming in the geological record, but it still has plenty of puzzles. Professor Daniela Schmidt has written an article in "Geology" highlighting a couple of them, which is an excuse to delve a little into this episode of climate change that has some similarities to, and some important differences from, modern climate change.   A […]
12:31 AM | The abundantly peculiar Arctic ground squirrel
They survive colder core body temperatures than any other known vertebrate, sustaining a temperature below freezing yet not becoming frozen. They emerge from hibernation with clock-like accuracy despite having spent 8 months in underground burrows below Arctic tundra and layers of snow, out of sight of the Sun. The Arctic ground squirrel is an adorable furball of mystery. Loren Buck, University of Alaska Anchorage Department of Biological Science professor, has been enticed by the truths he […]

5:51 AM | Deciding who should pay to publish peer-reviewed scientific research
There is an important discussion to be had about the future of scientific publications. As a practicing and publishing scientist, I am judged by the quality and quantity of my contributions to the scientific community. Traditionally, this comes down to counting how many papers I publish and weighting them by the quality (impact) of the journals where the papers appear. A fancy word for this is “Impact Factor,” which is a measure of the frequency papers in a particular journal are […]

11:11 PM | Breaking battery convention: new study indicates fast charging not necessarily detrimental to cycling lifetimes
It’s exciting in science when a conventional view is overthrown, as this opens the way for both new perspectives on old data and new experiments to design to test new theories.  A great example of this challenging of convention appears … Continue reading →

5:49 AM | Certain Arctic lakes store more greenhouse gases than they release
This is a re-post of an NSF press release New research, supported by the National Science Foundation (NSF), counters a widely-held scientific view that thawing permafrost uniformly accelerates atmospheric warming, indicating instead that certain Arctic lakes store more greenhouse gases than they emit into the atmosphere. The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh […]

5:55 AM | The 97% v the 3% – just how much global warming are humans causing?
A pair of climate scientists recently had a dispute regarding how much global warming humans are responsible for. Gavin Schmidt from Nasa represented the consensus of 96–97% of climate experts in arguing that humans have been the dominant cause of global warming since 1950, while Judith Curry from Georgia Tech represented the opinions of 2–4% of climate experts that we could be responsible for less than half of that warming. Curry is to be the featured speaker on this subject at a […]

10:44 PM | Something old, something blue, something borrowed, not much new: Labour’s climate policy
Mr February (aka Simon Johnson) looks at the Labour Party’s climate change policy and concludes it’s not exactly innovative. As I was saying in my previous post Labour do have a seven page climate change policy that is at first look pretty comprehensive. Labour will begin the transition to a low carbon clean energy economy […]

5:51 AM | Cutting Emissions Pays for Itself
This is a re-post from Audrey Resutek at the MIT Joint Program on the Science and Policy of Global Change  Study finds that savings from healthier air can make up for some or all of the cost of carbon reduction policies.  Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution.

2:35 AM | Memo to Labour: Calling fossil fuels “transition fuels” doesn’t make the carbon go away
The New Zealand Labour Party announced their climate change policy on 24 August; the Sunday before last Sunday. At first glance, it sounds refreshingly like a policy that takes anthropogenic global warming seriously. From the announcement: A Labour Government will put in place a comprehensive climate change strategy focusing on both mitigation and adaptation, establish […]
