U.N. climate report shows we can’t just phase out oil and gas; we have to deliberately dismantle existing infrastructure, such as coal plants in China and drilling in Alaska.NOAA and the Scripps Institution have two distinct monitors that have slightly different measurements. Scripps measured 423.8 parts per million and often runs a bit below NOAA. Both have been at the remote Mauna Loa volcano for decades, butand it’s been unable to use it since.
Scripps got their Mauna Loa site working and put one at Mauna Kea as well. Their data show that Mauna Kea is an accurate substation for Mauna Loa, Andrews said.“CO2 now is higher than any time in the last 4 to 4.5 million years when the atmosphere was about 7 degrees Fahrenheit warmer and sea levels were 5 to 25 meters higher,” Andrews said.
Back then, the build-up of carbon dioxide was much more gradual, allowing heat to build and ice to melt to raise seas, scientists said. “We are absolutely at levels unseen in human civilization,” Furtado said. “Humans are running a massive experiment on the Earth climate system via burning carbon, and the results are turning out
