Statistical and numerical models show that denitrification efficiency is a key parameter controlling the production of N2O from rivers, providing a target for river restoration projects.
Phytoplankton remove carbon dioxide from the atmosphere; a new study reveals that marine phytoplankton can also produce greenhouse gases when exposed to ultraviolet radiation.
Nuevos datos de exploración con aeronaves muestran que aunque la química atmosférica sobre regiones oceánicas remotas es una fuente considerable de producción de metanol, la emisión neta de metanol del océano es menor.
New aircraft survey data show that although atmospheric chemistry above remote ocean regions is a considerable source of methanol production, the ocean’s net methanol emission is minor.
Changing the way emissions are tallied may help litigators focus on the worst climate offenders and shape mitigation.
Continental shelves and estuaries are natural sources of nitrous oxide, but current global estimates of these emissions carry a lot of uncertainty, a problem that calls for regional studies.
A new website will soon compile and display all ancient atmospheric CO2 data.
Past ocean surface conditions suggest that over the past 800,000 years, atmospheric carbon dioxide levels typically rose on millennial timescales when Atlantic overturning was weaker and vice versa.
Rarely made detailed measurements of carbon dioxide and methane under lake ice reveal a story more complex than simple models of gas buildup, with surprising findings for climate change impacts.
Methane is generally considered secondary to carbon dioxide in its importance to climate change, but what role might methane play in the future if global temperatures continue to rise?
