When CO2 naturally increases in the atmosphere, pockets of ancient air preserved in ice show this CO2 rise happens gradually, over thousands of years. But today, carbon dioxide levels are skyrocketing as humans burn long-buried fossil fuels. “CO2 in the atmosphere has gone up 100 ppm in ...
US: The Carbon dioxide (CO2) levels peaked more than 50 per cent higher than pre-industrial levels in May, comparable to levels seen about 4 million years ago, according to scientists. 美国:科学家表示,5月份,二氧化碳(CO2)浓度达到峰值,比工业化前水平高出50%以上,与大约400万年前的水平相当。

Antarctic CO2 Levels Highest in 4 Million Years: Is That a Problem?Antarctica recently witnessed an event that last took place fourmillion years ago: Carbon...Thomson, Jason
Using ice cores drilled in Greenland and Antarctica, scientists havea pretty good recordof how the composition of Earth’s atmosphere has fluctuated over the last 800,000 years. That’s why scientists know carbon dioxide levels are higher than they’ve ever been in that amount of time. ...
The calculated median S(z) levels over the last 800 ky show variations from 356 to 815 ppm, with uncertainties on average of +96/−75 ppm (Fig. 2a). Fig. 2 The magnetic susceptibility (MS)–S(z) correlation of the Chinese Loess Plateau. a Back-calculated S(z) values ...
According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), far higher than at any point in the last 800,000 years, since before the evolution of homo sapiens. Holthaus spotted the new high on Sunday when ...
If CO2 levels and temperatures continue to rise, “our planet will change” and sea levels will rise by one or two meters in the next 200 years, he added. Related article'Dead corals don't make babies': Great Barrier Reef losing its ability to recover from bleaching ...
