CO2 levels in atmosphere reach record-breaking level

CO2 Levels In Atmosphere Reach Record-Breaking Level

An alarming new report from the Scripps Institution of Oceanography shows a record-breaking amount of CO2 in our atmosphere.

According to NBC, the new tests show the level of carbon dioxide, a green house gas considered most responsible for global warming, in our atmosphere is now at its highest in human history.

A little more than six decades ago, it was measured at about 300 parts per million. In April 2014, the gas measured in at more than 400 parts per million each day, according to USA Today. The outlet says scientists have been recording CO2 levels since the late 1950s along a graph called the Keeling Curve.

Scientists tweeted out the news via the Keeling Curve's account, noting the average CO2 level measured in at 401.33 parts per million.

More troubling - researchers at the National Oceanic and Atmospheric Administration, or NOAA, say much of the rise in carbon dioxide has come about in the past 100 years.

"Humans have caused carbon dioxide concentrations to rise 120 ppm since pre-industrial times, with over 90 percent of that in the past century alone."

But it doesn't stop there. James Butler, director of NOAA's Global Monitoring Division, says not only has the concentration itself increased, but the rate of increase has, too.

"The rate of increase has accelerated from about 0.7 ppm per year in the late 1950s to 2.1 ppm per year during the last decade."

So not only are we reaching higher concentrations of greenhouse gases in the atmosphere, but according to NASA, the process is also getting faster each year.

A writer for Slate spoke with Ralph Keeling, keeper of the Keeling Curve. Keeling says this new milestone is troubling and we must reduce fossil fuel burning.

"It's clear if we keep on the same course we're heading for a very different world. That carries with it lots of risks. If the climate changes fast enough, those risks are compounded."

Just because people don't like hurricanes, tornadoes, rain, floods etc., doesn't mean it isn't good for old mother earth! People are expendable and are really not as important as they think! Chances are this earth would probably be a better place with just the animals!

You're probably right. What other species fouls its own nest, and kills for fun?

Planet has cooled for last 18 years . That is a scientific fact . CO2 is what feeds plant life and trees and comes back to us as oxygen . There is no evidence that CO2 rising isnt a good thing . This is the biggest hoax and waste of resources all in the name of power and control . We are heading for a very different world anyway. Les face facts. The One major factor that will change are environment is not CO2 level it is NUCLEAR War and the amount of planned destruction that can occur . I have ZERO worry about C02 becuase It is a needed element for the envirionment . The planet has always changed which brought the rise of human beings. When are time is up it will have nothing to do with CO2 levels. ZERO ! Drill baby Drill .....Mine for Coal ......Sell Natural clean natural gas to Europe....etc......We can lower the concentration of poplution and have clean water . In FACT , Technology has brought them down and will continue to do so . Global Warming is a JOKE ! Follow the Money!

CO2 does nothing for us. Nitrogen is what the trees, etc., take in and return it in the form of oxygen. However CO2 can be harnessed and used for other purposes. Breathing in C02 is definitely not good for us medically speaking.

It's the uncontrolled world population increase. A 50% decrease in population, return to the pre-industrial society, and a stop in destroying the world's resources would be a start. Of course, I am not volunteering to step up and be first in line. THAT is why there will not be any reversal until major catastrophe occurs. I am in my 70s so I will probably not suffer the awful consequences; maybe no one alive today will have to. But, some future generation will have an awful experience.

Was Global Warming, then Climate Change now it is Rising Co2 Levels.

Ever time this scam is debunked they change the name.

I never thought about that. That's a fact that can't be argued.

Here we go again with pictures of the polar bears on the melting Ice ...
This Global warming bullshit is a scam .. A "Scientists' " research makes findings that shows global warming exists.. Jackpot ...Boom truck load of money for funding, years of job security and so on.

Scientists' research conclude no evidence of man made climate change.........

No more career in Science ......

Maybe we should kill all the cows in the world especially in India. If anyone knows anything about the polar bear they can swim for miles and do. If you look at the facts there is more polar ice than ever has been and some scientist predict we are going into an ice age. Hello! Facts are we can't control the weather and never have. But there are those out there that will believe anything. By the way I've got a bridge to sell you!

Where are the facts you cite? Give the public this information, it is extremely important that were know these in order to make a rational decision on what is true. WHERE ARE THE FACTS???? Rush Limbaugh cannot be quoted as a source.

Wouldn't you think that the people holding responsibility for the world would seriously consider leaving our forests and other oxygen producers alone/CO2 consumers alone?

With over 2 billion people in China & India don't think our 330 million people are going to matter much. Noting China's rapid growth, far outstripping ours, and their growth of Coal fired plants that are not as clean burning as ours, looks like we all better quit breathing out that CO2.I'm holding my breath!
