Oceanic methane seepage during warming
Atmospheric levels of methane, a potent greenhouse gas, vary greatly in the climate record and are usually thought to be due to emissions from continental wetlands. However, Tessa Hill et al. report that methane was released into the atmosphere from the oceans during the period of global warming associated with the most recent deglaciation. The results suggest that, at times, much more methane ...
متن کاملMethane oxidation linked to chlorite dismutation
We examined the potential for CH4 oxidation to be coupled with oxygen derived from the dissimilatory reduction of perchlorate, chlorate, or via chlorite (ClO(-) 2) dismutation. Although dissimilatory reduction of ClO(-) 4 and ClO(-) 3 could be inferred from the accumulation of chloride ions either in spent media or in soil slurries prepared from exposed freshwater lake sediment, neither of thes...
متن کاملEarly emergence in a butterfly causally linked to anthropogenic warming.
There is strong correlative evidence that human-induced climate warming is contributing to changes in the timing of natural events. Firm attribution, however, requires cause-and-effect links between observed climate change and altered phenology, together with statistical confidence that observed regional climate change is anthropogenic. We provide evidence for phenological shifts in the butterf...
متن کاملFuture Warming Patterns Linked to Today’s Climate Variability
The reliability of model projections of greenhouse gas (GHG)-induced future climate change is often assessed based on models' ability to simulate the current climate, but there has been little evidence that connects the two. In fact, this practice has been questioned because the GHG-induced future climate change may involve additional physical processes that are not important for the current cl...
متن کاملDiminished greenhouse warming from Archean methane due to solar absorption lines
Previous research has shown that methane may have been sustained at high concentrations in the Archean atmosphere, helping to offset lower insolation and solve the faint young sun problem. However, recent updates to the HITRAN (High-Resolution Transmission) line database have significantly increased the shortwave absorption by CH4 in comparison to older versions of the database (e.g. HITRAN 200...
