Unlike CO2, atmospheric methane concentrations are rising faster than at any time in the past two decades and, since 2014, are now approaching the most greenhouse-gas-intensive scenarios. The reasons for this renewed growth are still unclear, primarily because of uncertainties in the global methane budget. New analysis suggests that the recent rapid rise in global methane concentrations is predominantly biogenic-most likely from agriculture-with smaller contributions from fossil fuel use and possibly wetlands.

CHENNAI: Just words are not enough, Union government should officially annul methane and shale gas projects in the Cauvery delta as a policy decision.

Millions of abandoned oil and gas wells exist across the United States and around the world. Our study analyzes historical and new field datasets to quantify the number of abandoned wells in Pennsylvania, individual and cumulative methane emissions, and the attributes that help explain these emissions.

The assessment pointed out that the average global temperatures in 2015 had already gone beyond 1°C compared to pre-industrial times.

The southern bench of the National Green Tribunal has imposed a cost of Rs.

The European Investment Bank (EIB) has completed an analysis of its standards, criteria and procedures in relation to short-lived climate pollutants. The EIB also looked into the projects and sectors that it finances, the impacts they have on SLCP emissions and where the bank can scale up financing of projects that mitigate these emissions.

Globally averaged concentration of carbon dioxide in the atmosphere reached the symbolic and significant milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016 on the back of the very powerful El Niño event, according to the World Meteorological Organization's annual Greenhouse Gas Bulletin.

Scientists have found 500 seabed vents bubbling methane into the Pacific Ocean off the United States, roughly doubling the number of known U.S.

Airborne observations of greenhouse gases are a very useful reference for validation of satellite-based column-averaged dry air mole fraction data. However, since the aircraft data are available only up to about 9–13 km altitude, these profiles do not fully represent the depth of the atmosphere observed by satellites and therefore need to be extended synthetically into the stratosphere. In the near future, observations of CO2 and CH4 made from passenger aircraft are expected to be available through the In-Service Aircraft for a Global Observing System (IAGOS) project.

KOZHIKODE: How many of you would pinch yourself if you were told that methane emissions from livestock - in the form of burps and flatulence produced during enteric fermentation in the rumen of ani
