Global temperatures in February smashed previous monthly records by an unprecedented amount, according to Nasa data, sparking warnings of a climate emergency.

This year is shaping up to be possibly the hottest in human history after satellite readings showed how February obliterated the temperature record set in January.

The level of carbon dioxide in the atmosphere increased at a record pace last year, US government scientists reported, raising new concern about one of the top greenhouse gases and the effects of g

Japan's weather bureau said on Thursday the El Nino weather pattern, which is often linked to heavy rainfall and droughts, was expected to continue weakening and that there was a high possibility t

A delay in the onset of the La Nina weather pattern this year is likely to buoy crops across key growing regions in the United States, Australia and India, a leading weather forecaster said on Thur

International weather agencies see a normal to surplus monsoon for most parts of India this year, as if in response to a wish expressed in the Economic Survey 2015-16.

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.

Aerosol indirect effects suffer from large uncertainty in climate models and among observations. This study focuses on two plausible factors: regime dependence of aerosol-cloud interactions and the effect of cloud droplet spectral shape. We show, using a new parcel model, that combined consideration of droplet number concentration (Nc) and relative dispersion (ε, ratio of standard deviation to mean radius of the cloud droplet size distribution) better characterizes the regime dependence of aerosol-cloud interactions than considering Nc alone.

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.
