Marking yet another grim milestone for our warming planet NOAA reported that, for the first time in recorded history, global levels of carbon dioxide in the atmosphere averaged more than 400 parts per million (ppm) for an entire month—in March 2015.
“This marks the fact that humans burning fossil fuels have caused global carbon dioxide (CO2) concentrations to rise more than 120 parts per million since pre-industrial times,” said Pieter Tans, lead scientist of NOAA
This is not the first time the benchmark of 400 ppm has been reached. “We first reported 400 ppm when all of our Arctic sites reached that value in the spring of 2012,” explained Tans. “In 2013 the record at NOAA’s Mauna Loa Observatory first crossed the 400 ppm threshold.”
However, Tans said that reaching 400 ppm across the planet for an entire month is a “significant milestone.”The month of March brought “record warmth spread around the world,” with an average temperature of 1.53 degrees Fahrenheit above the 20th-century average—making it the hottest March ever recorded. www.ecowatch.com
These new figures, released by the National Oceanic and Atmospheric Administration, mean 2015 is on track to become the hottest year on record—a title held by 2014.
If the warming pattern holds true, 2015 will end up as one more piece of evidence showing the effect carbon emissions and greenhouse gases are having on climate change. Nine out of the 10 hottest years on record have come after 2000.
