Rise in Southeast Asia forest clearance increasing greenhouse gases
forest clearance greenhouse gases Southeast Asia
2021/8/3
Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly...
Rising greenhouse gases pose continued threat to Arctic ozone layer
ozone loss greenhouse gases climate change
2021/8/4
A new study shows that extremely low winter temperatures high in the atmosphere over the Arctic are becoming more frequent and more extreme because of climate patterns associated with global warming. ...
Dinosaurs lived in greenhouse climate with hot summers, study shows
VUB-UU greenhouse climate seasonal temperatures
2021/8/4
Researchers have developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter sum...
Effect of peat quality on microbial greenhouse gas formation in an acidic fen
peat quality microbial greenhouse gas formation an acidic fen
2010/1/21
Peatlands play an important role in the global carbon cycle and represent both an important stock of soil carbon and a substantial natural source of relevant greenhouse gases like CO2 and CH4. While i...
Chemolithoautotrophic production mediating the cycling of the greenhouse gases N2O and CH4 in an upwelling ecosystem
Chemolithoautotrophic production the greenhouse gases N2O and CH4 an upwelling ecosystem
2010/1/21
The high availability of electron donors occurring in coastal upwelling ecosystems with marked oxyclines favours chemoautotrophy, in turn leading to high N2O and CH4 cycling associated with aerobic NH...
In-situ measurements of oxygen,carbon monoxide and greenhouse gases from Ochsenkopf tall tower in Germany
In-situ measurements oxygen carbon monoxide greenhouse gases Ochsenkopf tall tower
2010/2/8
We present 2.5 years (from June 2006 to December 2008) of in-situ measurements of CO2, O2, CH4, CO, N2O and SF6 mixing ratios sampled from 23, 90 and 163 m above ground on the Ochsenkopf tower in the ...
Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates
N and P fertilization greenhouse gas exchange northern peatlands N deposition rates
2010/1/21
Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient availabi...
Greenhouse gas analysis of air samples collected onboard the CARIBIC passenger aircraft
Greenhouse gas analysis air samples CARIBIC passenger aircraft
2010/2/8
CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) is a long-term atmospheric measurement program based on the use of a comprehensive scientific ...
CO2 Higher Today Than Last 2.1 Million Years--Study Offers Detailed Look at Past Greenhouse Gas Levels（图）
CO2 Higher Today Than Last 2.1 Million Years Past Greenhouse Gas Levels
2009/12/10
Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth’s cycles of cooling and warming...
Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
Small scale controls greenhouse gas release N deposition rates
2010/1/15
In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environm...
The growing season greenhouse gas balance of a continental tundra site in the Indigirka lowlands,NE Siberia
season greenhouse gas balance continental tundra site Indigirka lowlands
2010/1/14
Carbon dioxide and methane fluxes were measured at a tundra site near Chokurdakh, in the lowlands of the Indigirka river in north-east Siberia. This site is one of the few stations on Russian tundra a...
The full greenhouse gas balance of an abandoned peat meadow
full greenhouse gas balance abandoned peat meadow
2010/1/14
Globally, peat lands are considered to be a sink of CO2, but a source when drained. Additionally, wet peat lands are thought to emit considerable amounts of CH4 and N2O. Hitherto, reliable and integra...
Greenhouse gas emissions from Indian rice fields:calibration and upscaling using the DNDC model
Greenhouse gas emissions rice fields calibration upscaling DNDC model
2010/1/12
The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) emissions from Indian rice fields with various ...
