Short affidavit on behalf of the Rajasthan State Pollution Control Board (RSPCB) in terms of the National Green Tribunal order dated January 22, 2025. The application was registered suo motu by the NGT on the basis of a news item titled "Toxic kilns pollution Aravallis; wildlife and locals suffer" appearing …
Intensification of the hydrologic cycle is a key dimension of climate change, with substantial impacts on human and natural systems1, 2. A basic measure of hydrologic cycle intensification is the increase in global-mean precipitation per unit surface warming, which varies by a factor of three in current-generation climate models (about …
Scientists have long known that birds are feeling the heat due to climate change. However, a new study of a dozen affected species in the Western Cape suggests their decline is more complex than previously thought -- and in some cases more serious. According to the study, published in Conservation …
Runoff from snowmelt is regarded as a vital water source for people and ecosystems throughout the Northern Hemisphere (NH). Numerous studies point to the threat global warming poses to the timing and magnitude of snow accumulation and melt. But analyses focused on snow supply do not show where changes to …
In a new investigation of model projections of greenhouse gas warming impact on the Mediterranean, Zappa et al (2015 Environ. Res. Lett. 10 104012) find that the decline in basin-wide precipitation scales linearly with the strength of the 850 hPa zonal wind over North Africa. This result supports previous findings …
Drought caused the most widespread damage in China, making up over 50 % of the total affected area nationwide in recent decades. In the paper, a Standardized Precipitation Index-based (SPI-based) drought risk study is conducted using historical rainfall data of 19 weather stations in Shandong province, China. Kernel density based …
Regardless of the harmful effects of burning fossil fuels on global climate other energy sources will become more important in the future because fossil fuels could run out by the early twenty-second century given the present rate of consumption. This implies that sooner or later humanity will rely heavily on …
Global warming and climate change is one of the most extensively researched and discussed topical issues affecting the environment. Although there are enough historical evidence to support the theory that climate change is a natural phenomenon, many research scientists are widely in agreement that the increase in temperature in the …
Global environmental change has implications for the spatial and temporal distribution of water resources, but quantifying its effects remains a challenge. The impact of vegetation responses to increasing atmospheric CO2 concentrations on the hydrologic cycle is particularly poorly constrained1, 2, 3. Here we combine remotely sensed normalized difference vegetation index …
How rainfall arrives, in terms of its frequency, intensity and the timing and duration of rainy season, may have a large influence on rainfed agriculture. However, a thorough assessment of these effects is largely missing. This study combines a new synthetic rainfall model and two independently-validated crop models (APSIM and …
The recent decline in Horn of Africa rainfall during the March–May “long rains” season has fomented drought and famine, threatening food security in an already vulnerable region. Some attribute this decline to anthropogenic forcing, whereas others maintain that it is a feature of internal climate variability. We show that the …
Groundwater in the carbonate aquifers of the southern Andhra Pradesh, India has approached to stress level as water table has declined due to increasing groundwater draft, low to moderate rainfall, less availability or absence of surface water sources and semi-arid climate. In Kallugotla watershed of Kurnool district, groundwater is overexploited …
Many tropical countries are exceptionally vulnerable to changes in rainfall patterns, with floods or droughts often severely affecting human life and health, food and water supplies, ecosystems and infrastructure. There is widespread disagreement among climate model projections of how and where rainfall will change over tropical land at the regional …
Many boreal waters are currently becoming browner with effects on biodiversity, fish production, biogeochemical processes and drinking water quality. The question arises whether and at which speed this browning will continue under future climate change. To answer the question we predicted the absorbance (a420) in 6347 lakes and streams of …
Says El Nino weather pattern has strengthened over the last two weeks The Australian Bureau of Meteorology said the recently emerged El Niño is now the strongest such event in nearly 20 years. Tropical Pacific Ocean temperature anomalies are at the highest levels since the El Niño that occurred between …
Combined sewer overflows (CSOs) occur in combined sewer systems when sewage and stormwater runoff are released into water bodies, potentially contaminating water sources. CSOs are often caused by heavy precipitation and are expected to increase with increasing extreme precipitation associated with climate change. Original Source
We here demonstrate that we can resolve the seasonality of the hydrologic cycle in the Amazon using an approach, opposite to general circulation models, in which we resolve convection and parameterize large-scale circulation as a function of the resolved convection. The results emphasize the key role of cloud albedo feedback …
About one-fifth of the worlds countries will face acute water shortage by 2040, as climate change will disrupt rainfall patterns. Population expansion will push up the demand for water, according to an analysis by non-profit research organisation, the World Resources Institute (WRI).
The climate of West Africa is characterized by a sensitive monsoon system that is associated with marked natural precipitation variability. This region has been and is projected to be subject to substantial global and regional-scale changes including greenhouse-gas-induced warming and sea-level rise, land-use and land-cover change, and substantial biomass burning. …
“It is safe to predict more unpredictability,” says a special report in The Economist on the Indian monsoon that continues to defy the best forecasts made by the best of models. The magazine recently published an account of ‘what might happen if India’s monsoon fails in future’ as part of …
Projected future trends in water availability are associated with large uncertainties in many regions of the globe. In mountain areas with complex topography, climate models have often limited capabilities to adequately simulate the precipitation variability on small spatial scales. Also, their validation is hampered by typically very low station density. …
