Large Increases in the Water Use Efficiencies of Three Tropical Forest Trees

Paper ReviewedRahman, M., Islam, M., Gebrekirstos, A. and Bräuning, A. 2020. Disentangling the effects of atmospheric CO2 and climate on intrinsic water-use efficiency in South Asian tropical moist forest trees. Tree Physiology 40: 904-916. Numerous scientific studies have been conducted in both laboratory and field environments to examine the impact of rising atmospheric CO2 on plant water use efficiency

Earth’s long-term climate stabilized by clouds

By Colin Goldblatt, Victoria L. McDonald and Kelly E. McCusker Abstract The Sun was dimmer earlier in Earth’s history, but glaciation was rare in the Precambrian: this is the ‘faint young Sun problem’. Most solutions rely on changes to the chemical composition of the atmosphere to compensate via a stronger greenhouse effect, whereas physical feedbacks

The risks of communicating extreme climate forecasts

For decades, climate change researchers and activists have used dramatic forecasts to attempt to influence public perception of the problem and as a call to action on climate change. These forecasts have frequently been for events that might be called “apocalyptic,” because they predict cataclysmic events resulting from climate change. In a new paper published

Carbon Dioxide: A $550-Billion Opportunity

By Irina Slav Anyone would be forgiven for being shocked when they see the words ‘carbon’ and ‘opportunity’ in one sentence. Carbon, after all, or rather carbon-oxygen compounds, are the ultimate enemy of the planet. It is something to be eliminated, not utilized. Nothing could be further from the truth. In addition to being an

Effect of high pressure carbon dioxide on the browning inhibition of sugar-preserved orange peel

By Jiao Zhang et al. Abstract In the present study, the effect of high pressure CO2 (HPCD) pretreatment on the browning of reducing sugar-preserved orange peel was evaluated. Fresh orange peel cubes were subjected to different pressures (4, 7.4 and 9 MPa; 31 °C; 20 min). The changes in the browning-related components during the processing

Field Studies Matter in Ocean Acidification Experiments

Paper ReviewedFoo, S.A., Koweek, D.A., Munari, M., Gambi, M.C., Byrne, M. and Caldeira, K. 2020. Responses of sea urchin larvae to field and laboratory acidification. Science of the Total Environment 723: 138003, doi.org/10.1016/j.scitoenv.2020.138003. Writing as background for their study, Foo et al. (2020) state that most so-called ocean acidification studies on marine calcifiers “have been conducted in a

‘Missing Ice Problem’ Finally Solved

During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers. Using innovative new calculations, a team of climate researchers led by the Alfred Wegener Institute has now managed

Optimized Ni-based catalysts for methane reforming with O2-containing CO2

By Guixian Deng et al. Highlights Methane reforming with O2-containing CO2 can directly use CO2 captured from air as raw material. Ni-based catalysts optimized by CeO2-ZrO2 has smaller Ni particle size and higher Ni dispersion. The interaction among Ni, CeO2 and ZrO2 results in high reforming activity. The optimized Ni-based catalyst owns dual active for methane and CO2 conversion.
