The horror! Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm

From the RESEARCH ORGANIZATION OF INFORMATION AND SYSTEMS and “it’s just a number” department, comes this breathless press release. Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm According to the 57th Japan Antarctic Research Expedition (JARE)/National Institute of Polar Research (NIPR), a daily mean atmospheric CO2 concentration value of 400.06 ppm was…

Scientists used fossilized plants, like this seed fern, to reconstruct the ancient atmospheric CO2 record from more than 300 million years ago.

Claim: reconstructing climate from 300 million years ago from fossils says we’re in trouble now

From the UNIVERSITY OF CALIFORNIA – DAVIS What the ancient CO2 record may mean for future climate change Deep-time reconstruction shows tropical forests can deeply impact climate change The last time Earth experienced both ice sheets and carbon dioxide levels within the range predicted for this century was a period of major sea level rise, melting…


Study: lakes started oxygenation problems long before fertilizers and climate change – blame urbanization

From the INSTITUT NATIONAL DE LA RECHERCHE SCIENTIFIQUE – INRS Urbanization: The historical cause of low oxygen conditions in European lakes The secrets lake sediments have to share A new study shows that hypoxia, i.e. low oxygen conditions, in European lakes started in 1850, becoming more widespread after 1900, long before the use of chemical fertilizers…
