It remains entirely unclear if the world as a whole will be able to cut its emissions of carbon dioxide fast enough to keep the global temperature rise below 2 degrees C over the next few decades. That's the level at which scientists say the most dire effects of climate change may be lessened or averted. Recent news has been both positive and...

It remains entirely unclear if the world as a whole will be able to cut its emissions of carbon dioxide fast enough to keep the global temperature rise below 2 degrees C over the next few decades. That's the level at which scientists say the most dire effects of climate change may be lessened or averted. Recent news has been both positive and... ![Electric-car rally in Geiranger, Norway [Image: Norsk elbilforening via Flickr]](https://images.hgmsites.net/tmb/electric-car-rally-in-geiranger-norway-image-norsk-elbilforening-via-flickr_100530088_t.gif)
Norway was one of the earliest nations to set a coherent and broad-based national plan to cut its carbon emissions, and then stick to it. For road transport, it plans to phase out sales of cars with internal-combustion engines by 2025 using a variety of carrots (financial incentives and special privileges) and sticks (very high taxes on... 
As children, we're all taught to turn off the lights behind us as we leave an empty room. But it seems Norwegians have taken that lesson one step further. Along a 5.5-mile stretch of road in Hole, Norway, smart streetlights automatically dim when nobody's around—then come back to full power when a car, pedestrian, or other object approaches... 
Ten years ago, energy security may have been as much a driving force behind electric cars for U.S. policymakers as climate change. Now, with continuous growth in domestic oil and gas production over that period, you just don't hear energy security discussed as much. Scientists agree that the effects of manmade climate change, on the other hand... 
We often speak of methods and technologies we can employ as a society to curb climate change, either by reducing carbon emissions or through other means. But less frequently do we talk about them in real terms, including how much excess carbon these methods and technologies can pratically remove from the atmosphere. That's where Drawdown, a... 
In discussions of climate change, much of the focus has been on the combustion of fossil fuels: coal, oil and its gasoline and diesel-fuel derivatives, and natural gas. Collectively, the trillions of tons of carbon dioxide emitted into the atmosphere by man since the start of the industrial revolution around 1750 have contributed to a massive rise... 
As the Trump administration abandons numerous U.S. efforts to rein in emissions of the climate-change gas carbon dioxide over time, another large polluter is pushing ahead with an aggressive plan to slash pollution from energy producers. China, currently the top carbon emitter and largest consumer of coal in the world, is moving to implement a... 
It's not just the world automotive industry that's grappling with rapid changes brought about by the need to reduce the effects of climate change. The world's fossil-fuel extraction, refining, and delivery industries are also faced with the reality that two centuries of burning their core products hurts the planet and has already exacerbated...
