Since being elected to the position of Supreme Pontiff in March, 2013, Argentine-born Pope Francis has shaken things up in the Vatican—to say the least. Long recognized as a champion of the poor, during his time as archbishop of Buenos Aires the pontiff was known for taking public buses to work and preparing his own meals. Now the pope is setting his sights on another glaring global injustice: climate change. Continue »

Wind energy is the primary, ready to install renewable energy resource today. It’s cheap, extremely quick to deploy, easy to integrate into an electric grid, and there’s plenty of it to go around. The levelized cost of electricity from wind power is about the same or cheaper than that from coal, the current fuel source of choice for much of the world’s electricity generation. Continue »

It seems like the summer on the US East Coast has been unusually cold so far, but the truth is that it's only been cold compared to the recent dramatic warming caused by the rapidly rising greenhouse gas concentration in the atmosphere. Continue »

The main point of this book is that we can still escape from the fossil fuel trap, and we can even prosper while we do it. But the details are kind of important..! Now, since this whole topic is somewhat dry, and talk of climate change can get to be very depressing very easily, I wanted to shatter the mold, and put the issue into a new context. And that’s what I did. And, the result of the investigative process shocked even myself. Continue »

We are responsible for fighting climate change, not because of our paltry individual carbon emissions, but because we are alive during an unprecedented moment. The greatest catastrophe in history is unfolding on our watch. We can either be bystanders and passive victims, letting climate change happen to us and watching as it horrifically reveals itself, or we can be active agents in fighting for what we hold dear. We can use our skills, talents, relationships, and resources to fight climate change with everything that we possess. Continue »

Less terrifying, more horrifying. That, more or less, was the between-the-lines takeaway from Friday's National Research Council (NRC) briefing on abrupt climate change. In one of the most shocking statements, Barnosky said the world's oceans are now undergoing a change in pH and temperature that is so rapid and severe, that if we stay on our business-as-usual emissions pathway, then we will see the most significant degradation in the world's oceans since 250 million years ago when there was the “end-Permian extinction event.” That was possibly the most extreme extinction event in Earth's entire history. Over 90% of marine species in the fossil record went extinct. Continue »

There has been some stuff in the past 2 months that could be linked to erratic jet stream behaviour - which in turn could be influenced by Arctic sea ice loss - like a series of storms battering Europe's Northwest, such as the St. Jude storm at the end of... Continue »

Climate scientist and leading expert on Arctic climate change, Jennifer Francis, says that while she would not attribute the current cold that's gripping the US to global warming, it is consistent with what she expects from global warming. I spoke with Francis this weekend about the connections she sees between weather, the jet stream, and climate change. Continue »

When it comes to global warming, one of my own pet peeves is how so many news articles imply or actually say that sea level rise cannot exceed some rate, and usually a relatively low one too. An article will often read something like: 'scientists think that in a worst-case scenario, sea levels might rise by as much as 2 feet by the end of the century.' But that's just not correct. Sea level rise researchers have been intentionally vague about how bad a “worst-case” scenario might be, because they don't rightly know with precision. Continue »

I recently took a ride in one of the most fuel-efficient and low-carbon-emitting cars on the road. The car appears to be just an ordinary Prius, a model that already boasts close to 50 miles per gallon efficiency, but this particular Prius also takes biogas as fuel. Continue »

How much of preindustrial methane can we attribute to human activity? A sizable fraction according to the much-debated “early anthropogenic hypothesis,” first proposed by William Ruddiman, a climate scientist with the University of Virginia. According to the theory, the prehistoric human greenhouse footprint, although exponentially smaller than it is today, may have been enough to stave off the onset of a new ice age thousands of years ago. Researcher Logan Mitchell has now added a new dimension to the issue with work just printed in Science.¹ Continue »

Mark Jaccard, an environment economist with Simon Fraser University in Vancouver, poured proverbial boiling oil on his government's reputation, saying that: “On climate, Canada is a rogue state. It's accelerating the global tragedy for obvious reasons of self-enrichment and disregard for the planet. More pipelines from the oil sands enable greater oil sands production.” Continue »

Two circular bands of winds called the westerlies are being changed by human-caused global warming. The consequences from these changes could become quite large and come on suddenly - quite the surprise for anyone who still thinks climate change is a future "slow" problem. Continue »
