They world is no longer safe, the earth is in terrible tears.
The World Meteorological Organisation predicted 2017 will again break records for concentrations of carbon dioxide and methane, but the growth rate will not be as fast because there is no El Niño effect.
The last time Earth experienced similar CO2 concentration rates was during the Pliocene era (three to five million years ago), when the sea level was up to 20m higher than now.
Prof Dave Reay, professor of carbon management at the University of Edinburgh, said: “This should set alarm bells ringing in the corridors of power. We know that, as climate change intensifies, the ability of the land and oceans to mop up our carbon emissions will weaken. There’s still time to steer these emissions down and so keep some control, but if we wait too long humankind will become a passenger on a one-way street to dangerous climate change.”
The report comes amid growing concerns that nature’s ability to deal with CO2 is weakening. Recent studies show forest regions are being cleared and degraded so rapidly that they are now emitting more carbon than they absorb.
The concentration of carbon dioxide in the atmosphere increased at record speed last year to hit a level not seen for more than three million years, the UN has warned.
The new report has raised alarm among scientists and prompted calls for nations to consider more drastic emissions reductions at the upcoming climate negotiations in Bonn.
“Globally averaged concentrations of CO2 reached 403.3 parts per million (ppm) in 2016, up from 400.00 ppm in 2015 because of a combination of human activities and a strong El Niño event,” according to The Greenhouse Gas Bulletin, the UN weather agency’s annual flagship report.
