Scripps Institution of Oceanography in San Diego confirms findings May 9; world’s top scientists call for action

May 10, 2013 (San Diego) -- Measurements around the world confirm that the rise in carbon dioxide levels have surpassed 400 parts per million –the highest in our planet’s history.
Before the industrial revolution in the 1900s, when coal and oil began to be burned on a large scale, C02 levels were never higher than 280 ppm.
But in recent years, the levels have risen 100 times faster than after the last ice age—providing clear evidence that the rise is far beyond any cyclical changes ever seen before. In fact, leading scientists around the world warn, climate change may soon be irreversible unless drastic changes are made to reduce this level to 350 ppm or lower.
