A World Meteorological Organization Greenhouse Gas bulletin has revealed that Co2 in the atmosphere is at it’s highest ever level., as reported by the IrishExaminer.
The carbon dioxide levels in the earth’s atmosphere increase at record rates, to levels from the dinosaur era. The UN suggests that these startling numbers could result in world sea levels rising by as much by 20 metres, as well as increasing global temperatures by as much as 3 degrees Celsius.
The report states that concentrations of CO2 in the atmosphere have increased from 400.0 in 2015 up to 403.3 parts per million in 2016. This accelerated growth rate is 50% faster than any average seen in the last ten years. This is a stark contrast to CO2 levels seen during the recent ice age cycles and warm periods, where levels ranged from 180-280 ppm.
The rising emissions are being put down to the continued heavy use of fossil fuels around the world, with coal and oil use as well as deforestation reaching record highs last year.
Scientists say this is the most accelerated rise in levels the world has ever experienced, as far as they can tell from the limited information they have of the past. They estimate the last time levels reached as high as 400 ppm, to be over 3 million years ago.
