Canadian rock legend Neil Young is worried about the environmental impacts of extracting oil from the tar sands near Fort McMurray, Alberta.
What do Neil Young, James Hansen, and John Cook all have in common? They've all used Hiroshima as an analogy to climate change; Dawn Stover at the Bulletin of the Atomic Scientists explores whether that's an accurate, and appropriate, analogy.
In the past month US President Barack Obama has focused the world’s attention on two threats that may not, at first glance, appear to have much in common.
Kennette Benedict writes in the Bulletin of the Atomic Scientists about the existential threat of climate change, and how the scientists who study and write about it are similar to the early atomic scientists who created, and then worried about, the threat that nuclear weapons posed to humanity: "Just as the Manhattan Project participants could foresee the coming arms race, climate scientists today understand the consequences of deploying the technologies that defined the industrial age. They also know that action now to reduce greenhouse gas emissions will mitigate the worst consequences of climate change, just as the Manhattan Project scientists knew that early action to forestall a deadly arms race could prevent nuclear catastrophe."
Utility-run energy-efficiency programs have grown robustly over the past decade and are one of the factors contributing to a cooling of the prospects for coal-fired power plants, according to a recent report.
Although reducing emissions of carbon dioxide is essential if climate change is to be slowed and then halted in the long run, researchers are analyzing a number of alternative pathways for reducing human-related forcing on climate over the next few...
Excellent, readable explanation of how HFCs are as damaging as carbon dioxide. Great info.
By Ben Geman President Obama is launching fresh battles over climate change with plans to curb emissions using executive powers that sidestep Congress — including controversial rules to cut carbon pollution from existing power plants.
