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 …
Western disturbances have a long history of climatological, synoptic and satellite observations based studies. In present study an attempt has been made to understand the different aspects of western disturbances like movement, associated convection, induce systems and associated weather. The western disturbances (WDs) during post monsoon and winter season have …
Scientific Assessment of Ozone Depletion: 2014 is the quadrennial report of the Scientific Assessment Panel (SAP) of the Montreal Protocol on Substances that Deplete the Ozone Layer. The SAP assesses the state of the depletion of the ozone layer and relevant atmospheric science issues every four years and provides Parties …
Humans increase the amount of reactive nitrogen (all N species except N2) in the environment through a number of processes, primarily food and energy production. Once in the environment, excess reactive nitrogen may cause a host of various environmental problems. Understanding and controlling individual nitrogen footprints is important for preserving …
A nitrogen (N) budget for Denmark has been developed for the years 1990 to 2010, describing the inputs and outputs at the national scale and the internal flows between relevant sectors of the economy. Satisfactorily closing the N budgets for some sectors of the economy was not possible, due to …
Our city has become so polluted that even a morning walk can make you very ill. Urgent steps like moving to Euro 5 norms and making diesel less attractive are needed but government is in no hurry Your early morning routine of a walk and workout out doors this winter …

Choice of variables, climate models and emissions scenarios all influence the results of species distribution models under future climatic conditions. However, an overview of applied studies suggests that the uncertainty associated with these factors is not always appropriately incorporated or even considered. We examine the effects of choice of variables, …
The atmospheric carbon dioxide (CO2) record displays a prominent seasonal cycle that arises mainly from changes in vegetation growth and the corresponding CO2 uptake during the boreal spring and summer growing seasons and CO2 release during the autumn and winter seasons. The CO2 seasonal amplitude has increased over the past …
Tropical cyclones are used as travelling thermometers to globally sample upper-tropospheric temperatures and help mitigate uncertainties due to discrepancies among different reanalysis data products.
This IPCC synthesis report released on 2 Nov 2014 says that global warming is “unequivocal”, that humanity’s role in causing it is “clear”. Bringing together several aspects from the three previous IPCC reports on climate science, impacts and the solutions it says that the impacts will last for thousands of …
Metallurgical activities have been undertaken in northern South America (NSA) for millennia. However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the …
The Tibetan Plateau (TP) has become a focus of strong scientific interest due to its role in the global water cycle and its reaction to climate change. Regional flux estimates of sensible and latent heat are important variables for linking the energy and hydrological cycles at the TP’s surface. Within …
Weather and Climate – Understanding Risks and Preparing for variability and extremes” is the theme of WMO’s latest Bulletin. Articles include: Activities for Early Career Scientists at the World Weather Open Science Conference, held in Montreal in August. International Migration in a Globalizing World: The Role of Youth, published by …
Climate change could alter the ecological impacts of the seasons, which could mean some big changes when it comes to our environment and agriculture. Now, scientists have taken a closer look at temperature variability across the globe in order to find out a bit more about potential impacts. "We describe, …
Biomass burning ia a major contributor to the atmospheric carbon budget and increases the concentration of many trace gases apart from the adverse effects on soil properties. However, in manyy parts of India, crop residue burning is a recurrent and widespread practice for disposal of the residues after harvest of …
NEW YORK: Sea ice around Antarctica has reached its highest level since measurement started in 1979, NASA said. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice record …
TANEGASHIMA, KAGOSHIMA PREF. – A satellite was launched Tuesday from the Tanegashima Space Center in Kagoshima Prefecture in a bid to improve the accuracy of weather forecasts related to natural disasters. The Himawari-8 weather satellite soared aloft aboard an H-IIA rocket at 2:16 p.m. It was expected to be placed …
Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, a new study has found. The study shows how aerosols can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future …
The UK is on course to have its driest September since records began, according to provisional figures released on Tuesday by the Met Office. The country received just 19.4mm of rain up to 28 September, about a fifth of the normal level. It has also been one of the warmest …
The strong present-day Asian monsoons are thought to have originated between 25 and 22 million years (Myr) ago, driven by Tibetan–Himalayan uplift. However, the existence of older Asian monsoons and their response to enhanced greenhouse conditions such as those in the Eocene period (55–34 Myr ago) are unknown because of …
