How fast do emissions need to decline to hit targets?

An excerpt from David Roberts on Vox.com, August 2017 The world’s nations have agreed, almost unanimously, to try to limit the rise of global average temperature to 2 degrees Celsius or less over preindustrial levels. To hit our target, emissions have to decline at a faster rate than almost anyone is talking about: Glen Peters To make this work, much modeling depends …

Study: Agriculture has released almost as much carbon into the atmosphere as deforestation, has large potential to change practices

By Chelsea Harvey. Washington Post, 23 August 2017 A Case IH tractor pulls a planter through a field as corn is planted in Princeton, Ill. (Daniel Acker/Bloomberg News) Agriculture has historically released almost as much carbon into the atmosphere as deforestation, a new study suggests — and that’s saying something.

Reducing the use of ozone-depleting substances from 2008 to 2014 eliminated equivalent of 50% of the reductions by the US for CO2 and other GHGsover the same period

Excerpt from Science Daily Reducing the use of ozone-depleting substances from 2008 to 2014 eliminated the equivalent of 170 million tons of carbon dioxide emissions each year. That’s roughly the equivalent of 50 percent of the reductions achieved by the U.S. for carbon dioxide and other greenhouse gases over the same period. The study was published today in Geophysical Research Letters, …
