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 question of how to assess trends in rainfall data is very relevant to that of climate change. A short review of prior work revealed that there was little consensus on the methodology to be adopted. Many methods had been tried and abandoned. Some methods had found comparatively wide acceptance …
The quantification of the carbon dioxide emissions impact associated with land-use change for biofuels production is complicated by the fact that the carbon costs from land-use change and the avoided emissions from substituting biofuels for fossil fuel in transport occur over an extended period of time. Estimating the net carbon …
Predicted or confronting you out of the blues, bad weather can give anybody the jitters, especially when each of your business moves, right from the stage of planning to that of execution, will have to be weighed against the vagaries of weather and climatic changes. Not surprisingly, demand for intelligent, …
Urbanization has a dynamic relationship with the physical environment. Urban and rural environments differ substantially in their microclimate. These climatic differences are primarily caused by the alteration on the surface of earth by human constructions and the release of artificially created energy into the environment. Inadvertent climate changes induced by …
Total atmospheric moisture content present in the atmosphere is less than 1% of total atmospheric composition. The atmospheric moisture variability accounts for nearly 10% variation in global hydrological cycle. The atmospheric moisture variability occurs in the form of cloud cover and hence in to the precipitation. A prior knowledge of …
Each year, on 23 March, the World Meteorological Organization, its 188 members and the worldwide meteorological community celebrate World Meteorological Day around a chosen theme. This day commemorates the entry into force, on that date in 1950, of the WMO Convention creating the Organization. Subsequently, in 1951, WMO was designated …
Net primary production (NPP) in the Yellow River Basin, China, during 1982-1999 was estimated with the CASA model using satellite data. The yearly NPP (NPPt) tended to increase during 1982-1999 throughout the Yellow River Basin. A large mean annual NPP for each grid cell was indicated in both the upper …
During a special ceremony at the Palais des Nations in Geneva, Switzerland, the World Meteorological Organization (WMO) and the International Council for Science released a report titled
Ozone pollution is produced by photochemical processes involving nitrogen oxides and volatile organic compounds in the lower atmosphere. Ozone levels become particularly high in regions close to high ozone precursor emissions during summer episodes with stagnant meteorological conditions, when high insolation and temperatures persist. In 2008, levels continued to exceed …

This latest WMO statement contains information for 2008 on global temperature, regional temperature anomalies, global precipitation, droughts, flooding and storms, La Ni
Carbon dioxide emissions and their associated warming could linger for millennia, according to some climate scientists. Mason Inman looks at why the fallout from burning fossil fuels could last far longer than expected. After our fossil fuel blow-out, how long will the CO2 hangover last? And what about the global …
marine sciences Rare corals aplenty According to researchers from James Cook University rare coral species might not be at high risks of extinction due to small population sizes.Their tendency to hybridize saves them. The previous prediction was that small population sizes led to decreased genetic diversity, which in turn decreased …
Global warming has become such an overriding emergency that some climate experts are willing to consider schemes for partly shielding the planet from the sun's rays. But no such scheme is a magic bullet.
IMD's long range forecast for the seasonal rainfall over the country as a whole and over different homogenous regions except northwest India have been accurate. However, the seasonal rainfall over northwest India and rainfall during July for the country as a whole have not been accurate. While the prediction overestimated …
This paper briefly sketches the history of the climate negotiations, ending with the most recent agreements in Bali. The paper then turns to the scientific basis of the work on mitigation. It introduces background concepts for proposals on mitigation, which identifies not only different schools of thought but a number …
