As worlds' economies show upturn from recession lows there is some unwelcome news for the Earth.

Carbon dioxide levels jumped by 2.67 parts per million since 2011 to total just under 395 parts per million, says Pieter Tans, who leads the greenhouse gas measurement team for the National Oceanic and Atmospheric Administration.

That's the second highest rise in carbon emissions since record-keeping began in 1959. The measurements are taken from air samples captured away from civilization near a volcano in Mauna Loa, Hawaii.

In 2009, the worlds nations agreed on a voluntary goal of limiting global warming to 3.6 degrees Fahrenheit over pre-industrial temperature levels. Since the mid-1800s temperatures have already risen about 1.5 degrees. Current pollution trends translate to another 2.5 to 4.5 degrees of warming within the next several decades.

Climate Scientist, James Hansen has said that a 2C degree increase is too much and is "a recipe for disaster".

Scientists track carbon pollution both by monitoring what comes out of factories and what winds up in the atmosphere. Both are rising at rates faster than worst-case scenarios that climate scientists used in their most recent international projections, according to Pennsylvania State University climate scientist Michael Mann.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
