The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
Australia's weather bureau said on Tuesday the chance of an El Nino developing this year had risen to about 50 percent after signs of renewed warming in tropical Pacific Ocean. The Bureau of Meteorology said six out of eight international models it surveyed indicated that sea surface temperatures in the …
The impact of Asian dust on the determination of cloud phase is analyzed over dust sources and downwind using cloud phase products from cloud-aerosol lidar and infrared pathfinder satellite observations (CALIPSO), atmospheric infrared sounder (AIRS), moderate resolution imaging spectroradiometer (MODIS), and polarization and anisotropy of reflectances for atmospheric sciences coupled …
Australia's run of abnormally warm weather has continued with the country recording its second-hottest February in data going back to 1910, according to the Bureau of Meteorology. Last month's national maximum temperatures were 2.35 degrees above the 1961-90 average, just shy of the record 2.41 degree anomaly set in 1983. …
Rainfall Variability is one of the key factors that affect agricultural production in any region. Hence the proper understanding of rainfall pattern and its trends may help water resources development and to take decisions for the developmental activities of that place. The present study is an attempt to evaluate the …
A mesmerising time-lapse of the world's rainfall and snowfall over the past year is being used by Nasa to track the factors behind climate change. It is the most detailed map of Earth's precipitation that has ever been created and allows scientists to follow the planet's weather patterns in near …
In this paper, we investigate the coagulation of interstitial aerosol particles (particles too small to activate to cloud droplets) with cloud drops, a process often ignored in aerosol-climate models. We use the GEOS-Chem-TOMAS global chemical transport model with aerosol microphysics to calculate the changes in the aerosol size distribution, cloud-albedo …
NAIROBI (Thomson Reuters Foundation) - The World Bank is working with other development finance institutions to raise some $500 million (320 million pounds) to modernise weather and flood forecasting services in Africa. Daniel Kull, a disaster risk specialist with the World Bank, said it was talking to lenders, including the …
Ground and satellite based measurements of spectral optical properties of aerosols have been carried out at Dehradun (DDN) in the Indo-Gangetic Plain (IGP) and Kavaratti (KVT) at Lakshadweep in southern Arabian Sea during pre-monsoon season (March–May) 2012. The measurements illustrate distinct seasonal impact on aerosol properties with maximum dust loading …
The American Southwest now has a 50 percent chance of entering a 30-year "megadrought." Scientists have examined the past in order to better understand rainfall patterns of today and have found that while the southwest is headed toward a drought, the Pacific Northwest will continue to warm with slightly drier …
Biomass burning (BB) largely modifies the chemical composition of atmospheric aerosols on the globe. We collected aerosol samples (TSP) at Cape Hedo, on subtropical Okinawa Island, from October 2009 to February 2012 to study anhydrosugars as BB tracers. Levoglucosan was detected as the dominant anhydrosugar followed by its isomers, mannosan …
The Weather Research and Forecasting model with Chemistry (WRF/Chem) simulation with the 2005 Carbon Bond gas-phase mechanism coupled to the Modal for Aerosol Dynamics for Europe and the Volatility Basis Set approach for Secondary Organic Aerosol (SOA) are conducted over a domain in North America for 2006 and 2010 as …
Fourteen of the 15 hottest years on record have occurred since 2000, according to the UN World Meteorological Organisation, as rising carbon emissions continue to trap heat and drive climate change. The WMO’s new analysis narrowly places 2014 as the hottest recorded since 1850, as have recent analyses from other …
Aerosol–cloud interactions are central to climate system changes and depend on meteorological conditions. This study identifies distinct thermodynamic regimes and proposes a conceptual framework for interpreting aerosol effects. In the analysis, ten years (2003–2012) of daily satellite-derived aerosol and cloud products are combined with reanalysis data to identify factors controlling …
Most recent analyses of the environmental impact of natural gas have focused on production, with very sparse information on emissions from distribution and end use. This study quantifies the full seasonal cycle of methane emissions and the fractional contribution of natural gas for the urbanized region centered on Boston. Emissions …
Last year was Earth's hottest on record in new evidence that people are disrupting the climate by burning fossil fuels that release greenhouse gases into the air, two U.S. government agencies said on Friday. The White House said the studies, by the U.S. space agency NASA and the National Oceanic …
An intense heat trough over the country's north-west may bring Australia's first observation of 50-degree temperatures in 17 years, forecasters say. Fifty (degrees) might be a push but high 40s are going to be likely. An area inland of Shark Bay in the Gascoyne region is showing up on Bureau …
Around 30 million cases of skin cancer will be prevented by 2030, thanks to successful implementation of the Montreal Protocol and its amendments says this new report produced by the Environmental Effects Assessment Panel (EEAP) of the Montreal Protocol. The report details various effects of UV radiation on human health, …
The biggest state in America, home to more ocean coastline than all others combined, has just set another record. This one, however, is nothing to cheer. For the first time in recorded history, temperatures in Anchorage did not drop below zero-degrees Fahrenheit (minus-17 Celsius) once in an entire calendar year. …
Most of Europe is forecast to be warmer than usual in January, with higher winds boosting power supply after the region’s mildest year in at least three decades helped push electricity and natural gas prices to record lows. A westerly airflow is expected to bring above-normal temperatures and strong winds …
