6:10 AM | Why ice sheets will keep melting for centuries to come
This article was originally published on The Conversation [UK] on Sep 26, 2014. Why ice sheets will keep melting for centuries to come By Eelco Rohling, University of Southampton It may already be too late to stop Antarctic ice sliding into the ocean. EPA Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore and melting into […]

5:18 AM | I am a scientist. Should I also be a journalist?
  I have always considered communication as an integral part of being a scientist. This is why I joined ClimateSnack, which improves my writing and provides a direct channel between early career scientists and a broad audience. I am no expert on scientific communication – rather, I am a young scientist trying to make sense […]Author informationGabriele MessoriI am Ph.D. student in the Physics Department at Imperial College London.

Anyone who follows the science of climate change knows that we are heading for environmental and social turmoil along our current path. In his new novel MiSTORY author Philip Temple imaginatively pictures what that turmoil might mean decades on from now. New Zealand is in a political mess. Conflict abroad and conflict within. A long-lasting […]

3:53 PM | The greenhouse effect and its role in the Earth’s climate
The Sun bathes the Earth in radiation. Much of this radiation reaches the surface, warming the planet and driving the climate.  The surface then emits heat (as infrared radiation), most of which does not escape to space, but is instead absorbed by gases in the Earth’s atmosphere.  These gases then warm, emitting further heat radiation both to space and back towards the Earth’s surface.  This is what we all know as the greenhouse effect.   The Earth’s energy […]

11:41 AM | Scientific meetings. The freedom to tweet and the freedom not to be tweeted
Some tweets from a meeting on Arctic sea ice reduction organised by the Royal Society recently caused a stir, when the speaker cried "defamation" and wrote letters to the employers of the tweeters. Stoat and Paul Matthews have the story.The speaker's reaction was much too strongly, in my opinion, most tweets were professional and respectful critique should be allowed. I have only seen one tweet, that should not have been written ("now back to science"). I do understand that the speaker feels […]

5:42 AM | Scientist in focus – Arctic adventurer Will Steger
As readers know, I often focus on the story, and history, of someone who makes an impact in climate change. This is the third such article and I think you will agree, it shows that it isn’t just lab scientists and academics that are shaping the conversation about climate change. Will Steger really rose to prominence as he led ventures to explore the polar regions of our planet. But those adventures were years in the making; they began in his childhood. Will was one of nine kids raised by […]

6:33 AM | Ocean Warming has been Greatly Underestimated
Key Points: The oceans are by far the largest heat reservoir on Earth, absorbing 93% of global warming. Because of this, accurate assessments of heat uptake are essential to balance the sea level budget, and for observationally-based estimates of climate sensitivity.      Prior to 2005, when the Argo global array of submersible floats became operational, ocean temperature was much more sparsely sampled, especially in the southern hemisphere, leading to larger […]

11:15 PM | Salinger: New Zealand is drying out, and here’s why
In this guest post Jim Salinger (currently working in Italy, but soon to return to these shores), takes a look at the climate influences on last year’s severe New Zealand drought. It first appeared on The Conversation. Over 2012 and 2013, parts of New Zealand experienced their worst drought in nearly 70 years. Drought is […]

6:50 AM | What's the role of the deep ocean in global warming? Climate contrarians get this wrong
This is a re-post from Greg Laden's Blog What is the role of the ocean’s abyss in global warming?1 I’ve already posted on a study published in Nature Climate change that shows that the amount of extra global warming related heat in the Southern Oceans is greater than previously thought. There is another paper in the same journal by Llovel et al, “Deep-ocean contribution to sea level and energy budget not detectable over the past decade.” This paper verifies previous […]

9:51 AM | The long hot tail of global warming - new thinking on the Eocene greenhouse climate
Past climate changes like the Eocene Hyperthermals left many traces in the geological record. These tell scientists a great deal about what the Earth looked like in these hothouse eras, the changes they made to rainfall, drought, landscape, oceans, ecosystems and life. Ultimately those records contain clues to the causes of the climate changes, and are signposts to the effects we can expect from modern climate change. A trio of new studies show that the Eocene Hyperthermals were the result of, […]

5:42 AM | GWPF funder Lord Leach – relying on unreliable sources of global warming information
DeSmog UK has found that libertarian banker Lord Leach is a likely funder of the anti-climate political advocacy group Global Warming Policy Foundation (GWPF). In May of 2009, Lord Leach gave a long speech in Parliament detailing his beliefs about global warming. The speech was full of inaccuracies, myths, and misinformation. Known as a Gish Gallop, the sheer number of false claims in the speech would require tremendous effort to debunk. Most telling were the sources that Lord Leach relied upon […]

The method at the heart of the new study is essentially identical to that used in the […]
