1:40 PM | A Scientific Debate
Guest posting from Bill Ruddiman, University of Virginia Recently I’ve read claims that some scientists are opposed to AGW but won’t speak out because they fear censure from a nearly monolithic community intent on imposing a mainstream view. Yet my last 10 years of personal experience refute this claim. This story began late in 2003 […]
12:44 PM | In the climate model jungle
The quote “all models are wrong, but some are useful”  by Box and Draper [1] reflects today’s discussion about climate modelling and how much people think we can extract from them:  If we desist from wanting to use models to depict “the true future”, which they cannot, a lot can be learned from using climate […]Author informationAnnemarie EckesI am Annemarie from Germany and study Climate Change at UEA.

5:52 AM | Andy Lacis responds to Steve Koonin
This is a re-post from And Then There's Physics I know Eli’s already posted Andy Lacis’s response to Steve Koonin on Judith Curry’s blog, but I thought it worth repeating. It’s a pretty impressive comment in terms of what it covers, so it’s worth reading in it’s own right. I do find myself amazed at what Steve Koonin has been willing to say. Ignoring that much of what he says suggests a woeful lack of understanding of the topic […]

This guest post is by Jonathan Musther, who has just published an amazing series of highly detailed maps projecting future sea level rise scenarios onto the New Zealand coastline. If you live within cooee of the sea, you need to explore his maps. Below he explains why he embarked on the project. The effect of […]
10:03 PM | Flying to the geo science flash mob in Vienna #EGU2015
You get used to it, but actually it is very strange. One week in spring, suddenly over 10 thousand geo scientists turn up in a middle European town, go into a huge building specially build for such mega flash mobs, talk about arcane topics and find others that want to do the same. Crazy. Such events also have environmental consequences. Especially travelling to Vienna produces much additional pollution. The UK Tyndall Centre recently produced a report stating climate scientists should set an […]

5:45 AM | New paper shows how sensitive the ocean biosystem is to climate change
Changes to the climate have had major impacts on the oceans and the biological systems that live there. A new study sheds more light on how fast these systems respond to changes. What the authors find is that short term climate changes can require 1,000 years for recovery. This means the current harm caused to the deep oceans by the changing climate will last for many centuries to come. The new study, published in the Proceedings of the National Academy of Sciences by Dr. Sarah […]

8:33 AM | British Council Institutional Links project – Environmental Health in Kazakhstan
I recently found out that I’d been successful with Newton-Al Farabi Institutional Links grant. Go me! It should be really interesting and will involve a lot of collaboration with a couple of universities out in Kazakhstan. I’ll also be working with a larger team here at Brunel than I normally would. I’m sure there’ll be more […]
5:50 AM | Global warming hiatus explained and it's not good news
You may have heard that global warming has 'paused' but it's only one part of a bigger picture and the search for understanding has equipped climate scientists with better tools than ever. "It is frustrating," says climate scientist Michael Mann from his office at Penn State University in the United States. "There certainly has not been a hiatus in global warming — global warming hasn't stopped, even though you still hear those contrarian talking points," he says. Professor Mann, the […]

11:30 AM | Autism Awareness month 2015
A reminder that April is Autism Awareness month.  I can't say very much first hand, but won't let that stop me from writing.  (As usual.)Couple notes.  One is, though I'm not autistic, I'm also not dead center 'normal' (whatever that is).  (what, you've noticed?).  I deviate from 'normal' in some directions that point in the direction of autism.  Not enough to be on the autism spectrum myself, but enough that my sister found me useful as a guidepost towards her […]

5:42 AM | The global warming 'pause' is more politics than science
The so-called 'pause' in the rate of global warming is false and distracting. It is a politically engineered excuse to avoid taking action on climate change. Over the past 17 years, the Earth has warmed rapidly, accumulating energy at a rate equivalent to more than four atomic bomb detonations per second. That's over 2 billion atomic bombs worth of heat built up on our planet since 1998. As discussed in a new book by one of us (Dana Nuccitelli) Climatology versus Pseudoscience, […]

10:03 PM | Ancient footprints on Beringia
You can see the depressions in the earth when the archaeologists point them out. Each house had a central room connected by tunnels to side rooms. Female relationships guided living arrangements: in a grandmother's house, each of her daughters' families would occupy one of the small side rooms. When they gathered there in rooms partially dug into the earth with walls built up with driftwood or whale bone and covered by sod, they achieved safety and warmth even during harsh... Read more
1:23 PM | The history of emissions and the Great Acceleration
 This is a repost from the Critical Angle blog. One of my pastimes is downloading data and playing around with it on Excel. I’m not kidding myself that doing this means anything in terms of original research, but I do find that I learn quite a lot about the particularities of the data and about the science in general by doing some simple calculations and graphing the numbers. There’s even occasionally a small feeling of discovery, a bit like the kind that you […]

7:20 PM | Changing your mind
The grave of Isaac Newton. Newton made himself vulnerable, wrote up his mechanics and optics very clearly. So that it could be falsified and was falsified. While he never repented his errors in public on facebook, his erroneous work did science a great service.Being a scientist is hard. No, not for the mathematics. Being a scientist is nothing for wimps because you have to make yourself vulnerable, write up your ideas so clearly that someone else can show them to be wrong. That is the […]

There are moments during your PhD where you wonder what on Earth you’re doing. You don’t want to get out of bed and work on this topic that does not interest you anymore.

5:45 AM | A revealing interview with top contrarian climate scientists
In 1990, University of Alabama at Huntsville scientists Roy Spencer and John Christy created a data set that estimates the temperature of the Earth’s atmosphere by using instruments on satellites (microwave sounding units) that measure microwave radiation in the atmosphere. According to their latestestimates, the Earth’s lower atmosphere has warmed significantly since satellite measurements began in 1979, but not quite as fast as thermometer measurements of […]

In previous posts on reasons why raw temperature data may show too little global warming I have examined improvements in the siting of stations, improvements in the protection of thermometers against the sun, and moves of urban stations to better locations, in particular to airports. This post will be about the influence of irrigation and watering, as well as improvements in the paints used for thermometer screens.Irrigation and wateringIrrigation can decrease air temperature by up to 5 degrees […]

11:30 AM | Citizen Science Versus Science
It's impolitic to say so, but I dislike the term 'Citizen Science'.  Scientists are supposed to be embracing 'Citizen Science' and all that.  But I can't get rid of the feeling that it's a patronizing term.  Nor can I ignore the echo that scientists are something other than citizens.  Lose-lose.The patronizing, maybe you don't see it.  But consider some other realms of activity.  I am, for instance, a runner.  Not a 'citizen runner', just a runner.  I […]

This article was originally published on The Conversation. Read the original article. Barry Jones, University of Melbourne Today’s Australians are, by far, the best educated cohort in our history –- on paper, anyway -– but this is not reflected in the quality of our political discourse. We appear to be lacking in courage, judgement, capacity to analyse and even simple curiosity, except about immediate personal needs. There are more than 1.1 million university students, both […]
