Printing boarding passes is sooooo 2005. Seriously, does anyone still print? My handy HP all-in-one printer collects more dust than print jobs. While it is true that most paper comes from managed forests, most of us just do not really have the need to print — a trend the paper industry, including the Paper and Packaging Board, whines about endlessly.

But sometimes we do need to print — for example, editing is easier for me to do on paper than staring at that laptop screen. And as an office tactic, distributing handouts at a meeting is a way to keep those rude colleagues’ eyes on the whiteboard and hands off their smartphones.

Climate negotiators meeting here in Paris have achieved a deal that could change the world. Conference chair and French foreign minister Laurent Fabius crowed that he had presided over a "historical turning point." Even when the hype has died down, that may turn out to be true. Even climate scientists who on Friday had sharply criticized an earlier draft of the text were convinced.  

The Paris Agreement commits the world to capping global warming to "well below 2 degrees Celsius above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 degrees C." To achieve that, it requires the world to "reach global peaking of greenhouse gas emissions as soon as possible" and "to undertake rapid reductions thereafter, in accordance with best available science." 

Lawrence Livermore researchers and collaborators have found that most climate models overestimate the increase in global precipitation due to climate change.

Specifically, the team looked at 25 models and found they underestimate the increase in absorption of sunlight by water vapor as the atmosphere becomes moister, and therefore overestimate increases in global precipitation.

The team found global precipitation increase per degree of global warming at the end of the 21st century may be about 40 percent smaller than what the models, on average, currently predict.

Is Paris the beginning of the end for coal? Coal burning is declining fast in both of the world's two largest carbon dioxide emitters, China and the the United States, with resulting declines in the emissions of both countries. The fuel looks incompatible with a world that warms by no more than two degrees Celsius, bringing calls for its rapid phaseout as the world is "decarbonized." 

But, with or without a deal here in Paris later this week, will the calls be heeded? Has the demise of King Coal been greatly exaggerated?  

In the U.S., "coal has gone from boom to bust," says Michael Brune, executive director of the Sierra Club. The black stuff's share of electricity generation has sunk from 53 percent to 35 percent in just five years.
 

The rainfall and snowpack so far this autumn have been encouraging, but the stubborn reality is that California is still mired in drought. While farmers from Bakersfield to Fresno to Redding are screaming about water quotas, California residents say they are doing what they can, from pulling out grass lawns to capturing what little rainwater exists.

Climate change is likely to have far-reaching impacts on food security throughout the world, especially for the poor and those living in tropical regions, according to a new international report that includes three co-authors from the National Center for Atmospheric Research (NCAR).

It’s never been easier for us to get where we want to go, but our growing transportation systems mixed with development are taking a serious toll on wildlife, from tiny amphibians to large mammals, and pushing some who are already in danger of disappearing even closer to the brink.

A new report from the Endangered Species Coalition, No Room to Roam: 10 American Species in Need of Connectivity and Corridor, focuses on imperiled species who need just what the title says: room to roam.

Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future.

National and local conservation groups today condemned a decision by the U.S. Forest Service to continue pressing to open national forest roadless areas in Colorado to coal mining.

In a notice filed today, the Forest Service announced it would move forward by issuing a draft environmental impact statement on the proposal to pave the way for mining. The proposal would reopen a loophole in the “roadless rule” for national forests in Colorado to enable Arch Coal — the nation’s second largest coal company — to scrape roads and well pads on nearly 20,000 acres of otherwise-protected, publicly owned national forest and wildlife habitat in Colorado’s North Fork Valley.

Faced with a raw materials scarcity due to climate change, food and drink giants have turned to a sustainable management in order to protect the environment and ensure their future viability. The global population is expected to rise from 7.3 billion today to 9.7 billion in 2050, according to UN projections. As a consequence, according to a survey published in July by FoodDrinkEurope, this will require a 60% increase in food supplies globally, as well as a 30% rise in global demand for water for agriculture.
