Chronic nitrogen deposition has measureable impacts on soil and plant health. We investigate burning emissions from biomass grown in areas of high and low NO x deposition. Gas and aerosol-phase emissions were measured as a function of photochemical aging in an environmental chamber at UC-Riverside. Though aerosol chemical speciation was not available, results indicate a systemic compositional difference between biomass grown in high and low deposition areas.

This Compendium of Environment Statistics 2015 published by the Ministry of Statistics and Programme Implementation is the sixteenth edition of its series and covers five core parameters - biodiversity, atmosphere, land/soil, water and human settlements.

With the mercury topping 36.5 degrees Celsius on Saturday, Karachi witnessed it the hottest day of the month in over two decades, the Met office said on Sunday.

The El Niño–Southern Oscillation (ENSO) affects the tropospheric concentrations of many trace gases. Here we investigate the ENSO influence on mercury concentrations measured in the upper troposphere during Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container flights and at ground at Cape Point, South Africa, and Mace Head, Ireland. Mercury concentrations cross-correlate with Southern Oscillation Index (SOI) with a lag of 8 ± 2 months.

There is a high sediment mercury levels in Artic which is more prone for pollution in the region, a recent study has revealed.

After two straight years of drought, there's finally reason to hope for a normal monsoon this year.

Last month was the hottest January in modern times, US data showed on Wednesday, the latest in a string of heat records fuelling concerns over the pace of climate change.

The El Niño that caused record temperatures, drought and floods over the last year has passed its peak strength but will continue to have humanitarian impacts for months to come, the UN has said.

The past month is the warmest since record keeping began in 1880, which continues a nine-month streak of record high monthly temperatures, according to the latest report released by the U.S.

This year has got off to a scorching start, with global temperatures marching to new highs as a giant El Nino rode on the back of creeping climate change, data from Japan and the US show.
