Scientists have recorded the highest level of CO2 emissions on earth since records began

The last time earth’s atmosphere contained this much CO2 was more than three million years ago

SCIENTISTS IN THE United States have detected the highest levels of planet-warming carbon dioxide in Earth’s atmosphere since records began.

It has sounded new alarm over the rise of man-made greenhouse gas emissions.

The Mauna Loa Observatory in Hawaii, which has tracked atmospheric CO2 levels since the late 1950s, detected 415.26 parts per million on Saturday morning.

It was also the first time on record that the observatory measured a daily baseline above 415 ppm.

The last time earth’s atmosphere contained this much CO2 was more than three million years ago, when global sea levels were several metres higher and parts of Antarctica were blanketed in forest. 

“It shows that we are not on track with protecting the climate at all. The number keeps rising and it’s getting higher year after year,” Wolfgang Lucht, from the Potsdam Institute for Climate Impact Research said. 

“This number needs to stabilise,” he added. 

Levels of CO2 - one of a trinity of greenhouse gases produced when fossil fuels are burnt – are climbing at a rapid pace. 

Ralph Keeling, director of Scripps Institution of Oceanography’s CO2 programme, said the trend would probably continue throughout 2019 — likely to be an El Nino year in which temperatures rise due to warmer ocean currents.

“The average growth rate is remaining on the high-end. The increase from last year will probably be around 3ppm whereas the recent average has been 2.5ppm,” he said. 

“All of human history has been in a colder climate than now.”

“Despite the Paris climate agreement, despite all the speeches and the protests — we are not seeing that we are bending the curve yet,” he added.

Paris agreement

The 2015 Paris agreement calls for efforts to block the rise in earth’s temperature from rising above two degrees. 

The last four years were the four hottest on record and, in spite of the Paris deal and increasing public awareness of the problem, mankind continues to break its own emissions records, year on year.

Earth’s average surface temperature has already increased by one degree since pre-industrial times due to man-made emissions.

While there is some disagreement over what would constitute ‘safe’ atmospheric CO2 levels, there is a broad consensus that 350ppm – a level surpassed in the late 1980s – would stave off runaway global warming.

    As a very frequent traveller, I have used the scanners in US airports and could care less to be honest. I’ve seen people more exposed in their photo albums on Facebook. The queues for the scanners are much quicker than the standard queues, the person instructing you how to stand can’t see the scan anyway (the images are monitored remotely) and it’s not like they’re going to discuss your naked form with anyone you know! In Schipol recently, I was subjected to a pat-down that would have been classed as a sexual assault in the real world and I was livid about it. I’d rather have been offered the option of the scanner.

    Great…NOT!!!… Dublin yet again are going to follow the example of London Airports it would seem… I personal have a problem with the level of intrusion and the general feeling of being treated like dirt that flying by plane has become. I am flying via London in a couple of weeks, but since I have now found out that this full-body scan is now mandatory there, I will no longer fly in our out of London unless it is my destination. As for the effectiveness of these scanners (http://en.wikipedia.org/wiki/Millimeter_wave_scanner), I have serious doubts in general that any of this treatment like cattle is improving anyone’s safety.

    Maybe I do. However what I have to hide is not going to bring down a plane, e.g. prosthetics including breast prostheses, and other medical equipment normally hidden, such as colostomy bags are all things that someone may not want the people around him/her to be aware of. I am sure you can think of a whole range of other things that are the private business of individuals and of no concern to airport authorities. However all these things will be viewed and displayed by this machine with little if in any improvement to airport security.

    If the image is as per the picture above then i’d have no issue with this tbh as it’s not particularly invasive.

    Id be more concerned with the potential radiation effects. Had a quick look through the literature… There is Very little peer reviewed information supporting it as non genotoxic- as claimed by manufacturers. May not be a concern for those who take a couple of flights a year but there could be legitimate concerns from frequent flyers with prolonged exposure to the technology.

    Germany trialled these in Hamburg and the machines produced an staggering failure rate. 61% of pax passed through without a problem, 31% had to be padded down (hard). In 54% of cases a false alarm was recorded. Result: significant delays in processing passengers.

    Germany has abandoned plans to use scanners at its airports and will not reconsider until the technology is more reliable and meets “high security standards,” interior minister Hans-Peter Friedrich said Wednesday

    What bunch of sheeple we have become. These are dangerous microwaves. Seriously read into this a bit more. There have been many problems with this in America. Not least the TSA agent who shot his colleagues because they made jokes about the size of his penis after a training scan.

    Are xray machines not cancerous? Do the guards hide behind lead walls like a nurse at the hospital?

    @Bob – When I spoke to DAA earlier they were keen to stress that they’re not “x-ray machines”, in that their intensity is much lesser than a standard booth.

    Yep, they are cancerous…No, guards not behind lead walls, just eating up the radiation like it’s good for them and getting cancer..From Chicago, TSA heads now have cancer from operating these type of machines.. http://healthland.time.com/2011/06/30/did-airport-scanners-give-boston-tsa-agents-cancer/ So, we’ve option A – groping and pat downs to make sure we’re not “dangerous” or option B – an invasive scan that will shower you in radiation..Just great…This is 1984 people…

    @Fred (and Bob): The machines that TIME article refers to are a different type of ‘booth’-style scanner than is being considered in Dublin.

    Jesus.These scanners are on TRAIL for 18 months in staff areas.Not been used in public areas.Which mean they are not coming in at dap untill ALL tests are carried out.What does it take for people to cop on.These are the times we live in.get used to it.

    Looks like milimeter wave scanners only penetrate the clothes and are stopped by skin. So why not just tape a load of contraband to your leg, then wrap it in pigskin (the most common human analog from Mythbusters). Sorted.
