4:09 AM | My AGU talk on tackling climate myths in a free online course
This post is based on an invited presentation I gave at the 2014 American Geophysical Union Fall Meeting in San Francisco. The talk was titled Applying Agnotology Based Learning in a MOOC to Counter Climate Misconceptions. In it, I explained the approach taken in our upcoming MOOC (Massive Open Online Course) titled Making Sense of Climate Science Denial. For the last few years, I’ve been talking to people about agnotology-based learning.  Usually they blink or stare at me with […]

9:08 AM | Clarity on Antarctic sea ice.
I’ve always been a skeptic when it comes to Antarctic sea ice. I’m not referring here to the tiresome (and incorrect) claim that the expansion of sea ice around Antarctica somehow cancels out the dramatic losses of sea ice in the Arctic (NB: polar bears don’t really care if there is sea ice in Antarctica […]
9:07 AM | Rising air and sea temperatures continue to trigger changes in the Arctic
This article is a reprint of a news release posted by the US National Oceanic and Atmospheric Administration (NOAA) on Dec 17, 2014. Arctic is warming at twice the rate of anywhere else on Earth A new NOAA-led report shows that Arctic air temperatures continue to rise at more than twice the rate of global air temperatures, a phenomenon known as Arctic amplification. Increasing air and sea surface temperatures, declining reflectivity at the surface of the Greenland ice sheet, […]
1:29 AM | Science Storytelling Workshop at AGU14
"What does this look like?" "Zombies!" one of the scientists suggested. "Right," the cinematographer agreed. He reinforced the idea of shifting the frame to give the person on camera space for their gaze to travel - 'Lookroom'. He'd noted before that when there's an empty space looming behind a person's back it creates tension. Perhaps a zombie is about to stagger up from behind. Whoever's filming needs to keep in mind framing, or the way that visual elements are placed... Read more

10:12 AM | What happens if we overshoot the two degree target for limiting global warming?
This is a re-post from Carbon Brief by Roz Pidcock Two degrees is the internationally-agreed target for limiting global warming, and has a long history in climate policy circles. Ambition that we can still achieve it is running high as climate negotiators gather in Lima to lay the groundwork for a potential global deal in 2015. But against this optimistic backdrop, greenhouse gas emissions have continued to rise. With each passing year the scale of the task looms ever larger.  There […]

9:32 PM | Interview: Powering the Top of the World
Powering the Top of the World is a new documentary by Christoph Mazur and Chris Emmott, from Imperial College London. It explores energy supply in Nepal, and the innovative solutions to sustainable energy provision in some of the most remote parts of the world. With over 1.2 billion people with no access to electricity across the globe, these issues are echoed in countries the world over. Christoph Mazur speaks to Climatica about their work in Nepal, the moviemaking process, and their […]
4:25 PM | Worldwide weird weather words
To celebrate both the Christmas period and the variety of nationalities within the UEA ClimateSnack group we have put together this group post. In the UK it is often said that as a nation we are obsessed with the weather, here we demonstrate that many countries have idioms relating to the local meteorological conditions.

7:54 AM | 2014 will be the hottest year on record
For those of us fixated on whether 2014 will be the hottest year on record, the results are in. At least, we know enough that we can make the call. According the global data from NOAA, 2014 will be the hottest year ever recorded. I can make this pronouncement even before the end of the year because each month, I collect daily global average temperatures. So far, December is running about 0.5°C above the average. The climate and weather models predict that the next week will be about […]

10:05 AM | Two degrees: Will we avoid dangerous climate change?
This is a re-post from Carbon Brief by Simon Evans Limiting warming to no more than two degrees has become the internationally accepted target for climate policy, as we saw in  the first blog of our series of pieces looking at the two degrees limit. Scientists think the risks of climate change increase as temperatures rise. Two degrees isn't a 'safe' level of climate change, but nor is it a red line with only chaos beyond, as we'll see in part three. It is a readily understood and useful […]

English goes silent on carbon deficit costs The Government is refusing to discuss what impact a 2030 carbon deficit will have on the economy – despite warnings from Treasury. Finance Minister Bill English has confirmed to Carbon News that Treasury is predicting carbon prices of between $10 and $165 a tonne between 2021 and 2030, […]
9:55 AM | Two degrees: The history of climate change’s ‘speed limit’
This is a re-post from Carbon Brief by Mat Hope & Rosamund Pearce Limiting warming to no more than two degrees has become the de facto target for global climate policy. But there are serious questions about whether policymakers can keep temperature rise below the limit, and what happens if they don't. As climate negotiators meet in Lima to discuss a new global climate deal that could limit warming to two degrees or less, we look at each of the issues in turn. Here, we take a look at […]

The landscape for science blogging, the public discourse on climate and our own roles in the scientific community have all changed radically over the last 10 years. Blogging is no longer something that stands apart from professional communications, the mainstream media or new online start-ups. The diversity of voices online has also increased widely: scientists […]

7:02 AM | Global warming continues despite continuous denial
Human emissions of greenhouse gases cause the Earth to warm. We’ve known that for decades – actually for over 100 years. But how do we measure warming? How fast is the planet heating? Turns out, this is conceptually easy to answer, even though it is difficult to implement the required measurements. In order to measure how fast the planet is heating, we can measure the difference in incoming and outgoing energy at the top of the atmosphere (just like keeping track of a bank account […]
