Whatever Happened to the Global Warming "Pause?" September 2, 2015.
It is only September, but, absent a massive volcanic eruption or asteroid impact, 2015 will be, by far, the hottest year on the instrumental record. The culprit is a massive El Niño that is compounding the warming effects of rising greenhouse gas emissions. This year’s scorching heat will mean that the three hottest years on record will have occurred within the same five-year stretch: in 2010, 2014, and 2015. More
A Conversation with Geoffrey Parker. July 23, 2015.
More and more people are recognizing that, to understand climate change today, we must study its past. The study of past climates has never been more popular or more interdisciplinary, and its findings are increasingly reaching the media. Policymakers are taking notice - although not always in ways we would like - and the general public is, too. In fact, this site now attracts around 100,000 visitors annually, and we hope to build on that number as we add new features and content. To that end, we are launching a new Climate History Podcast on iTunes. Within days, you will be able to search for it on iTunes, but you can already subscribe by clicking on this link. More
Is Climate Change Behind the Syrian Civil War? July 8, 2015.
Across much of the world, climate change is making, or will soon make, environments less capable of supporting human life. Anyone who has seen the movie Mad Max will be familiar with the assumption that a hotter, and, in some places, drier climate will drive people to greater competition. When that competition is for the essentials of life, and there is not enough to go round, people resort to violence. In short: global warming could make war even more common than it is today. More
A Conversation with Miranda Massie. June 1, 2015.
Climate change might be the most important issue the world faces today. Readers of this site will know it has a rich history. It helped trigger the evolution of sentience in primates, created conditions that encouraged agriculture, and influenced the rise and fall of civilizations from Bronze Age Greece to the Ottoman Empire. Its present, as we have recently been reminded, affects us all. In just the last week, dozens have died in Texan floods, hundreds in an Indian heat wave, and thousands in a Syrian war provoked, in part, by drought. The future looks even more alarming. The IPCC and WMO have both warned that the world, and our place in it, may be almost unrecognizable in a century. So why is there no climate change museum? More
Heading North for the Arctic Winter. April 20, 2015.
By Benoit S. Lecavalier.
In early February, I had the opportunity to gather with fellow scientists in Longyearbyen, the most northerly permanent village in the world. The town is in the Norwegian Archipelago of Svalbard at approximately 80°N latitude, slightly over a 1,000 km from the North Pole. For that reason, it is the perfect place to explore the key issues currently facing the glaciological community. The most important: how do glaciers and large ice sheets respond to climate change, and affect global sea levels? This question can only be answered by unravelling complex relationships with potentially dire consequences for our civilization. More
