Global carbon emissions are on track to reach 400 parts per million, a level not seen in at least 5 million years. This exceeds the 350 ppm threshold that scientist James Hansen warned could destabilize the earth's climate. The Mauna Loa observatory in Hawaii expects the 400 ppm milestone will be hit in 2013 due to increased emissions from population growth and industrialization relying on fossil fuels over the past 50 years. Experts warn that crossing this threshold without action means atmospheric CO2 levels could surpass 450 ppm within decades, which a Scripps Institution scientist called a "national disaster warning." This milestone underscores the urgent need for governments to support clean energy and emissions reductions.

1. Global Carbon Emissions Set
to Hit Alarming 400 Parts Per
Million Milestone

2. A national disaster warning: in up to five million years,
this is the first time that the concentration of carbon
dioxide in our atmosphere is approximately to reach 400
parts per million (ppm). Monday on The guardian
reports, former NASA scientist James Hansen warned
that levels over 350ppm would destabilize the earth’s
climate, but now we have far exceeded that figure with
a record-breaking weekly average of 398.5ppm
recorded. While in May 2013, researchers at the Earth
Systems Research Laboratory in Hawaii expect we will
hit the 400ppm milestone.

3. Aside from many other issues like global fraud for
example there are many else the government should
give attention to. According to The Guardian, the US
government has been monitoring atmospheric carbon
dioxide levels at the Mauna Loa station located at an
elevation of 11,115 feet since 1958. During the time
when it was first ascertained, CO2 levels stayed at a
manageable 316ppm, but in the past five decades
population expansion coupled with the growth of
industrialized nations hooked on fossil fuels and meat
has saturated the atmosphere with heat-trapping gases.

4. “I wish it weren’t true but it looks like the world is
going to blow through the 400ppm level without
losing a beat. At this pace we’ll hit 450ppm within a
few decades,” Ralph Keeling, a geologist with
the Scripps Institution of Oceanography which
operates the Hawaiian observatory, told The
Guardian. It is as if it was a national disaster
warning.

5. This “sobering milestone” should be a wake up call
for governments to support clean energy and slash
emissions, said Tim Lueker, an oceanographer and
carbon cycle researcher with Scripps CO2 Group.
