Indo-Asian News Service: During the week of April 6 to 12, average carbon dioxide (CO2) levels touched 404.02 parts per million (ppm), the highest-ever in recent human history - and 15 percdent above the levels of 350 ppm scientists say is ideal for Earth. The months of February, March and April had monthly average CO2 levels higher than 400 parts per million (ppm), the first time in recorded history all three months have reached such levels, according to the keystone Mauna Loa observatory in Hawaii. These rising levels...

Global CO2 levels surge past 400-ppm mark for first time in millions of years
2015-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Global CO2 levels rose above 400 parts per million for the first time ever in the modern era in March 2015, marking a significant milestone in the planet's progression toward a warmer future. The measurements were released by the National Oceanic and Atmospheric Administration. The last time CO2 levels were this high was 3 million years ago during the Pliocene era. There was little ice at the poles then. Ellesmere Island, which is today part of the Canadian tundra, had forests growing on it. ...

Mongabay: For the first time in human history, carbon dioxide concentrations averaged out at 400 parts per million (ppm) worldwide in March, according to NOAA. Carbon dioxide concentrations have likely not hit such levels in two million years-long before Homo sapiens evolved. "This marks the fact that humans burning fossil fuels have caused global carbon dioxide concentrations to rise more than 120 parts per million since pre-industrial times," said Pieter Tans, lead scientist of NOAAs Global Greenhouse...

NASA Warns About High CO2 Levels That Are Greening The Planet
2015-05-07 18:42:24| Apparel - Topix.net
The National Aeronautics and Atmospheric Administration warned atmospheric levels of carbon dioxide reached new levels during March, levels the space agency says are a harbinger of dangerous global warming. "Passing the 400 mark reminds me that we are on an inexorable march to 450 ppm and much higher levels," said Michael Gunson, the head of NASA's global change and energy program.
A Global Milestone: CO2 Passes 400 PPM

Climate Central: For the first time since record keeping began, carbon dioxide levels have surpassed 400 parts per million (ppm) globally, according to newly published data for March. CO2 emissions are the main driver of climate change and have risen more than 120 ppm since pre-industrial times. The planet has warmed 1.6°F over that period as well. This isn't the first time 400 ppm has made news. In May 2013, CO2 measurements taken at Mauna Loa surpassed 400 ppm for the first time. Measurements have been taken...
