5:50 AM | Ancient ocean currents may have changed pace and intensity of ice ages
This is a re-post from the National Science Foundation Climate scientists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. In a paper published this week in the journal Science Express, researchers report that the deep ocean currents that move heat around the globe stalled or may have stopped at that time, possibly due to expanding ice cover in the Northern Hemisphere. "The research is […]

3:47 AM | Friday melts, weird weather and whales (it’s been a long time…)
It’s been a long time since my last post: apologies for that. You may blame a bad cold, an urgent need for root canal work, the peak of the truffle season (and truffle tours for culinary heroes1 ), the start of pruning and political distractions for the drop off in activity here. Normal service should […]

5:49 AM | Scientist in focus – meteorologist and climate communicator Paul Huttner
Meteorologists have the tools to clearly understand how humans are affecting the Earth’s climate. For folks who study weather every day, the changes they’ve seen defy natural explanation. But most meteorologists have to balance their very limited airtime and their reporting obligations with a desire to convey the reality of climate change. It’s very rare that a meteorologist, let alone a major media organization, take time to bring in-depth discussions to their listeners. But, […]

11:02 PM | Anthropogenic climate change and glacial loss explained in a single number: 25!
A new analysis combining climate modeling with glacier dynamics has given us the first estimation of the percent of glacier loss directly due to anthropogenic climate change.  This is strong evidence and important data to understand to educate the general … Continue reading →

11:52 AM | Climate Change Impacts in Labrador
In 1534, famed explorer Jacques Cartier described Labrador as "the land God gave to Cain". This comparison is inevitably linked to Labrador’s rugged coastal landscapes dotted with deep inlets, fiords and rugged tundra. Culturally the region is steeped in complexity with three distinct indigenous populations intertwined with settlers and settler descendants. In the north lies the Inuit settlement area of Nunatsiavut, where its predominantly Inuit residents are spread across 5 small […]

12:03 PM | Can isotopes help define the Anthropocene?
By Dr Jonathan Dean, Prof Melanie Leng and Prof Anson Mackay   The Anthropocene is a term that is increasingly being used to refer to the current interval in geological time in which humans have become a dominant force of global environmental change. It was coined by Prof Eugene Stoermer, a biologist, in the 1980s and popularised in the early 2000s by Prof Paul Crutzen, an atmospheric chemist. It is now indisputable that humans are leaving their mark on the planet (see the recent Climatica […]

5:38 AM | Global warming denial rears its ugly head around the world, in English
As people’s understanding of climate science grows, among both experts and non-experts alike, we become more accepting of the fact that humans are the driving force behind global warming. That’s because the evidence supporting human-caused global warming is overwhelming; hence rejection of that reality is usually based on an incomplete understanding of the scientific evidence. In Australia, Prime Minister Tony Abbott’s chief business adviser Maurice Newman offered a prime […]

5:29 AM | Climate scientists dub this year’s El Niño “a real enigma”
This is a re-post from Roz Pidcock at Carbon Brief Last month, forecasters were predicting with  90 per cent certainty we'd see an El Niño by the end of the year, driving severe weather patterns worldwide. But with little sign so far of the ocean and atmospheric changes scientists expected, those odds have dropped off quite a bit. We'll probably still see an El Niño before the year's out but it's unlikely to be a strong one, scientists are saying.   What is an El […]

4:03 AM | The merits of plasticity
Whether a species thrives or flags can have resounding consequences. When we think of our changing world, we imagine an ecosystem occupied by organisms which are interlinked. Photosynthesizers like plants and phytoplankton which harvest energy from the Sun occupy the lowest trophic level, while the herbivores that eat them are on the second trophic level, supporting higher level carnivores. When something goes wrong in one part of this pyramid / web / food chain, disconnects can […]

Siberia has explosion holes in it that smell like methane, and there are newly found bubbles of methane in the Arctic Ocean. As a result, journalists are contacting me assuming that the Arctic Methane Apocalypse has begun. However, as a climate scientist I remain much more concerned about the fossil fuel industry than I am […]

5:56 AM | Global warming is moistening the atmosphere
We have long suspected that greenhouse gases which cause the Earth to warm would lead to a wetter atmosphere. The latest research published by Eul-Seok Chung, Brian Soden, and colleagues provides new insight into what was thought to be an old problem. In doing so, they experimentally verified what climate models have been predicting. The models got it right… again. To be clear, this paper does not prove that water vapor is a greenhouse gas. We have known that for years. Nevertheless, the […]

5:25 AM | New study finds fringe global warming contrarians get disproportionate media attention
A new study led by Bart Verheggen surveyed 1,868 scientists studying various aspects of climate change, asking them several questions mainly focused on what’s causing global warming. They survey also asked the respondents, How frequently have you featured in the media regarding your views on climate change? The answers to this question reflect whether the media is really fair and balanced on the subject of global warming. A truly balanced media would give equally proportional attention […]

3:48 AM | Survey confirms scientific consensus on human-caused global warming
This is a repost from Bart Verheggen's blog. A survey among more than 1800 climate scientists confirms that there is widespread agreement that global warming is predominantly caused by human greenhouse gases. This consensus strengthens with increased expertise, as defined by the number of self-reported articles in the peer-reviewed literature. The main attribution statement in IPCC AR4 may lead to an underestimate of the greenhouse gas contribution to warming, because it implicitly includes the […]
