Mejorando el presupuesto mundial para el metanol atmosférico
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.
Improving the Global Budget for Atmospheric Methanol
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.
The Surprising Source of Greenhouse Gas Emissions
Changing the way emissions are tallied may help litigators focus on the worst climate offenders and shape mitigation.
Marine Nitrous Oxide Emissions off Northwest Europe
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.
2020 Hindsight: A Website for All Paleo-CO2 Data
A new website will soon compile and display all ancient atmospheric CO2 data.
Atlantic Circulation Consistently Tied to Carbon Dioxide
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.
What Lies and Waits Beneath Lake Ice?
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, Climate Change, and Our Uncertain Future
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?
EPA Reassesses Feasibility of Plan to Increase Fuel Efficiency
This January, the Environmental Protection Agency (EPA) finalized mileage standards set in 2012. Now, at the push of the auto industry, EPA and other agencies are going back for another look.
