Over hundreds of thousands of years, sediments from southern Greenland have been making their way into the ocean, where they’re carried by underwater currents to a location in the Labrador Sea called the Eirik Drift. Here, they settle on the ocean floor, where they form a record of history, accumulating in layers that document the
Paper ReviewedMacdonald, C.A., Anderson, I.C., Khachane, A., Singh, B.P., Barton, C.V.M., Duursma, R.A., Ellsworth, D.S. and Singh, B.K. 2021. Plant productivity is a key driver of soil respiration response to climate change in a nutrient-limited soil. Basic and Applied Ecology 50: 155-168. While the positive effects of rising atmospheric CO2 on plant growth are well-recognized, climate alarmists often
By Roger Pielke Jr. It is prudent to stress test the eurozone’s resilience but not if the underlying assumptions are wrong. The late Kenneth Arrow, who won the 1972 Nobel Prize in economics, once worked as a long range weather forecaster in the US military. When he realised that these weather forecasts were no more
By Matthew Cappucci Scientists identify possible connection between the solar cycle and whether El Niño or La Niña is present When it comes to long-term hurricane forecasts, tornado predictions in the Plains or prospects for winter rain in California, you’ll often hear meteorologists refer to El Niño or La Niña. They’re phases in a cycle
Fantastic Findings: German Study Shows Added CO2 Has Led To 14% More Vegetation Over Past 100 Years!
By P. Gosselin Almost everyone with even just a fraction of a science education knows Co2 is fertilizer to vegetation and that the added 100 or so ppm in our atmosphere over the past decades have been beneficial to plant growth and thus led to more greening of the continents. Yet, some alarmists still sniff
By Jim Steele Most people are unaware that the greenhouse gases CO2 and H2O, both warm & cool our planet. When I mention that CO2 has a cooling effect, I’m amazed by the hateful tirades from paranoid people who dismiss scientific truth as “dangerous misinformation”. However, discussions about temperature inversions have occasionally induced more respectful
It’s considered canonical that global-scale atmospheric levels of CO2 from thousands of years ago can be precisely discerned just by examining air bubbles in ancient snow and ice from Antarctica. But an examination of the CO2 levels in modern snow and ice shows there are gigantic discrepancies between the measurements of CO2 in ice versus
By Martin Enserink When Philip Munday discussed his research on ocean acidification with more than 70 colleagues and students in a December 2020 Zoom meeting, he wasn’t just giving a confident overview of a decade’s worth of science. Munday, a marine ecologist at James Cook University (JCU), Townsville, was speaking to defend his scientific legacy.
Salk scientists quantify process to permanently store plant-captured CO2 as SiC, a valuable material for electronics LA JOLLA–(May 6, 2021) Plants are unparalleled in their ability to capture CO2 from the air, but this benefit is temporary, as leftover crops release carbon back into the atmosphere, mostly through decomposition. Researchers have proposed a more permanent,
Strong glacial-interglacial variability in upper ocean hydrodynamics, biogeochemistry, and productivity in the southern Indian Ocean
By Deborah Tangunan et al. Abstract In the southern Indian Ocean, the position of the subtropical front – the boundary between colder, fresher waters to the south and warmer, saltier waters to the north – has a strong influence on the upper ocean hydrodynamics and biogeochemistry. Here we analyse a sedimentary record from the Agulhas
