6:41 AM | Food, Fossil Fuels and Filthy Finance
It is depressingly apparent that powerful forces in the global economy are set to carry on with the exploration for and use of fossil fuels as a primary source of energy for decades to come. Oxfam has produced a report identifying the confluence of fossil fuel companies, governments and investors which givers momentum to the […]

8:17 PM | Should we suppress the fire?
A GLOBAL VIEW ON FIRES AND THEIR MANAGEMENT Forest fires have been around for as long as plants have been widespread and oxygen has been available to fuel their burning hunger. And so fires have become an integral part of many forest ecosystems. Unsurprisingly the earth has seen variations of fire activity in the past […]Author informationStephane MangeonPursuing a CASE PhD between the Met Office and Imperial College London, I am developing a parameterization to include fires within the […]

1:45 PM | Ocean heat storage: a particularly lousy policy target
The New York Times, 12 December 2027: After 12 years of debate and negotiation, kicked off in Paris in 2015, world leaders have finally agreed to ditch the goal of limiting global warming to below 2 °C. Instead, they have agreed to the new goal of limiting global ocean heat content to 1024 Joules. The […]

1:33 AM | Carbon News 20/10/14: Chile’s carbon tax, soil SOS and more pressure on dirty investments
Chile’s new tax could open carbon doors for NZ Chile’s new carbon tax potentially offers New Zealand an opportunity to offset some of its own agricultural greenhouse gas emissions, says economist Dr Suzi Kerr. The $US5-a-tonne carbon tax slipped into Chilean law last month as part of a package of tax reforms. Soils SOS as […]

12:28 AM | The chemical map of otoliths
It's about the size of a diamond and comes from the inner ear of a fish. This tiny construction holds a treasure trove of information, a calcium carbonate microchip made of bone and accessed by a laser. Let's take a look at the science of otoliths. An otolith is a fish ear bone (from oto- ear and lithos- stone). From every population of fish Heidi Golden finds, she preserves a number of otoliths to take back to the lab. These... Read more

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 […]

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 […]

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 […]

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, […]
