2:18 PM | The People’s Monsoon
You might expect that a term like “monsoon” has an agreed definition and that scientists can explain when it starts and ends. Defining the monsoon is actually quite contentious, leading to the publication of many different definitions. Some define the monsoon onset according to rainfall, wind change, cloud top temperatures, or a combination of these […]Author informationMathew Stiller-ReeveI am a PhD student at the Bjerknes Centre for Climate Research.

8:46 AM | Constructive and External Validity for Climate Modeling
It’s been a while since I’ve written about the question of climate model validation, but I regularly get asked about it when I talk about the work I’ve been doing studying how climate models are developed. There’s an upcoming conference organized by the Rotman Institute of Philosophy, in London, Ontario, on Knowledge and Models in […]

5:54 AM | Unpacking unpaused global warming – climate models got it right
Although the global climate has continued to build up heat at an incredibly rapid rate, there has been a keen focus among climate contrarians and in the media on the slowdown of the warming at the Earth’s surface. The slowdown is in fact a double cherry pick – it focuses only on the 2% of global warming that heats the atmosphere (over 90% heats the oceans), and it only considers the past 10–15 years. Nevertheless, because there was so much attention paid to the surface warming […]

10:26 PM | Mosquitoes on the move: climate change and its effect on vector-born diseases
If you live in Florida, like I do, you come to truly fear and loathe these guys: the Aedes albopictus, better known as the tiger mosquito.  Or any other mosquito, for that matter.  In the US, we actually have it … Continue reading →

9:00 AM | The Tea Party consensus on man-made global warming
Dan Kahan, Professor of Law and Psychology at Yale, produced a remarkable plot about the attitude towards global warming of Tea Party supporters. Kahan of the Cultural Cognition Project is best known for his thesis that climate "sceptics" should be protected from the truth and that no one should mention the fact that there is a broad agreement (consensus) under climate scientists that we are changing the climate. Without having the scientific papers to back it up, reading WUWT and Co. leaves […]

8:48 AM | Volcanoes and climate change
What happens to the atmosphere when volcanoes erupt? Can volcanic eruptions lead to climate change? In 2010 the eruption of Eyjafjallajökull in south Iceland brought air traffic in northern Europe to a standstill for almost seven days. Now, the Bárðarbunga volcano, which has erupted beneath the Dyngjujökull glacier in central Iceland, is being intensively studied by scientists. On average, there are around 50-60 volcanic eruptions around the world each year. When volcanoes […]

Originally posted on Azimuth:? Why do ostriches stick their heads under the sand when they’re scared? They don’t. So why do people say they do? A Roman named Pliny the Elder might be partially to blame. He wrote that ostriches “imagine, when they have thrust their head and neck into a bush, that the…

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 […]
