Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, according to this new report by the World Meteorological Organisation (WMO). This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface …
The paper investigate probability distribution of daily minimum temperature during winter (November to February) based on meteorological data of Jalgaon weather station for the period of agriculture years 1973-74 to 2015-16. Original Source
Summer monsoon season 2011 was highlighted with unprecedented rainfall in some districts of Punjab in the second week of August 2011 causing significant damage to public and private properties. An attempt has been made in this paper to identify the observational aspects, main synoptic system, Physical process and thermodynamic features …
The impacts of the industrial structure on the atmospheric environment in Shenzhen are analyzed by utilizing climate, environmental and economic data over the past 35 years of Shenzhen, a rapid developing megacity in China.
A carbon sink is a system that absorbs carbon dioxide from the atmosphere. Having committed a target of creating an additional carbon sink the equivalent of 2.5 billion to 3 billion tonnes carbon dioxide by 2030, India now anticipates that it might not be able to meet that through forests …
During the months of June and July 2013, over the Euro–Mediterranean area, the ADRIMED (Aerosol Direct Radiative Impact on the regional climate in the Mediterranean region) project was dedicated to characterize the ozone and aerosol concentrations in the troposphere. It is first shown that this period was not highly polluted …
Attribution of Antarctic ozone recovery to the Montreal protocol requires evidence that (1) Antarctic chlorine levels are declining and (2) there is a reduction in ozone depletion in response to a chlorine decline. We use Aura Microwave Limb Sounder measurements of O3, HCl, and N2O to demonstrate that inorganic chlorine …
A new study has shown that decreasing carbon dioxide levels in the atmosphere led to a phenomenon of increased global cooling one million years ago. A decline in atmospheric carbon dioxide (CO2) levels led to a fundamental shift in the behaviour of the Earth’s climate system around one million years …
Aerosols are significant to the Earth’s climate, with nearly all atmospheric aerosols containing organic compounds that often contain both hydrophilic and hydrophobic parts. However, the nature of how these compounds are arranged within an aerosol droplet remains unknown. Here we demonstrate that fatty acids in proxies for atmospheric aerosols self-assemble …
Pluto’s atmosphere is cold and hazy. Recent observations have shown it to be much colder than predicted theoretically, suggesting an unknown cooling mechanism. Atmospheric gas molecules, particularly water vapour, have been proposed as a coolant; however, because Pluto’s thermal structure is expected to be in radiative–conductive equilibrium, the required water …
Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800 000 years, according to the World Meteorological Organization's Greenhouse Gas Bulletin. The abrupt changes in the atmosphere witnessed in the past 70 years are without precedent. Globally averaged concentrations of …
The amount of carbon dioxide in the earth's atmosphere grew at record rate in 2016 to a level not seen for millions of years, the United Nations said on Monday. It said this has the potential to fuel a 20-metre rise in sea levels and add 3 degrees Celsius to …
Changes in tropical wetland, ruminant or rice emissions are thought to have played a role in recent variations in atmospheric methane (CH4) concentrations. India has the world’s largest ruminant population and produces ~ 20% of the world’s rice. Therefore, changes in these sources could have significant implications for global warming. …
The analysis of the results of the study has revealed that the warm dirt has accelerated the catastrophe of global warming At a time when climate change has the world in a tight grip, a recent study has issued a warning saying that, warming soils are releasing more carbon, thus …
Climate change will significantly increase the amount of severe turbulence worldwide by 2050-2080, said the study published in the journal Geophysical Research Letters. London: Mid-air turbulence is likely to increase by up to three times in the coming decades due to climate changes, increasing the risk of injuries to passengers …
In response to global warming, the Brewer–Dobson circulation in the stratosphere is expected to accelerate and the mean transport time of air along this circulation to decrease. This would imply a negative stratospheric age of air trend, i.e. an air parcel would need less time to travel from the tropopause …
TOKYO (Reuters) - Japan’s weather bureau projected on Monday that there are no active El Niño or La Niña patterns now and that it sees a 60 percent chance of normal weather conditions continuing through winter. The projection was the same as last month. There is a 40 percent chance …
The Earth's atmosphere and the Earth's magnetic field protects local life by shielding us against Solar particle flows, just like the sun's magnetic field deflects cosmic particle radiation. Generally, magnetic fields can affect terrestrial life such as migrating animals. Thus, terrestrial life is connected to astronomical interrelations between different magnetic …
We evaluate the Community Atmosphere Model Version 5 (CAM5) with a higher-order turbulence closure scheme, named Cloud Layers Unified By Binomials (CLUBB), and a Multiscale Modeling Framework, referred as the “super-parameterization” (SP) with two different microphysics configurations to investigate their influences on rainfall simulations over Southern Amazonia. The two different …
Even as carbon emissions from use of fossil fuels flattened out in the past few years, the monster El Nino of 2014-16 caused over 3 billion tonnes of carbon to get released into the atmosphere, pushing carbon dioxide concentration to record levels. This was announced by scientists after they analysed …
An international, peer-reviewed publication released each summer, the State of the Climate is the authoritative annual summary of the global climate published as a supplement to the Bulletin of the American Meteorological Society. The report, compiled by NOAA’s Center for Weather and Climate at the National Centers for Environmental Information …
