    Atmospheric concentrations of CO2 will shatter the symbolic barrier of 400 parts per million (ppm) this year and will not fall below it our in our lifetimes, according to a new Met Office study.
    The paper’s lead author, Professor Richard Betts of the Met’s Hadley Centre and Exeter University, said the fact that the 400ppm threshold had been breached a year earlier than expected carried a warning for the future.
    Carbon dioxide measurements at the Mauna Loa observatory in Hawaii are forecast to soar by a record 3.1ppm this year – up from an annual average of 2.1ppm – due in large part to the cyclical El Niño weather event in the Pacific, the paper says.
    The surge in CO2 levels will be larger than during the last big El Niño in 1997/98, because manmade emissions have increased by 25% since then, boosting the phenomenon’s strength.

    As it turned out, "the unfortunate milestone" was reached on Tuesday May 10 at 8am, local time, said Paul Krummel, who heads the CSIRO team analysing data from the most important site in the southern hemisphere. (See chart below.)

    "It's a bit sooner than we expected," Mr Krummel told Fairfax Media. "It just rocketed up there."

    A report out earlier this year from the World Meteorological Organization noted atmospheric readings of CO2 at the Mauna Loa site in Hawaii rose 3.05 ppm in 2015 alone – the biggest increase in the 56 years of research.


    It's not going to go back below 400 ppm for a very long time unless we get very good at mitigation," Mr Krummel said.Global CO2 levels were running at roughly 280 ppm up until about 1850 when they started to take off. (See chart below).

    Climate scientists, such as David Karoly at Melbourne University, note that when other greenhouse gases, such as methane, are included, the situation is even bleaker.

    The so-called carbon dioxide-equivalent level that takes in the full global warming impact is now about 485 ppm.

    Looking at your CO2 level increasing in time , there is a relationship between human population increase vs. time so to decrease CO2 rate we have to decrease the rate of human reproduction. Or eventually a disaster will help population decrease, and the survivors will adjust them selve to the new environment whatever it will be.

    An other cruel way looking slow down develop in helping undeveloped nation to be developed .

    ...or.....we all do what we are currently trying to do, which is to reduce the amount of CO2 emitted per person.

    There is no reason whatsoever to think that the amount of CO2 emitted has to remain fixed, or that the rate of development of countries such as Malaysia has to be reduced.

    Friend I did my part My house is well insulated, I drive a car which give 25 mile / gal. My house is surrounded by tree which some I have planted , I drive about 8000 mile / year . I feel I have dome my part

    Well there you go! So there is no need to resort to exterminating half the human race or holding back developing countries. We just need a lot more of that from all societies. (I was quite surprised - and proud - to read the the UK generated 25% of its electricity from renewables last year. Things have quietly come on a long way.)

    Or simply use new technology and methods that produce less CO2

    This is like one hand in a hot water bucket and the other in an ice bucket . But we in the great lakes ( Chicago ) it was a beautiful cool spring

    Reducing birthrate is not exterminating anyone. It is just reducing birthrate, and has to be part of any solution to reduce climate change (indeed, it must be part of reducing any negative impact humanity has on the Earth.)
