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 …
n 2011, Lake Erie experienced the largest harmful algal bloom in its recorded history, with a peak intensity over three times greater than any previously observed bloom. Here we show that long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and …
The Compendium of Environment Statistics aims to serve as reference material for environment planners and policy makers as well as other Government and Non-Government organizations and research institutions to increase awareness and knowledge of the environmental situation of the country. The need for improvements in the field of data and …
The Arctic has seen rapid sea-ice decline in the past three decades, whilst warming at about twice the global average rate. Yet the relationship between Arctic warming and sea-ice loss is not well understood. Here, we present evidence that trends in summertime atmospheric circulation may have contributed as much as …
Plants with rising atmospheric carbon dioxide (CO2) level in the environment may change their nutrient demands to sustain growth. The mechanisms concerning iron dynamics in plants under the interactive effect of salinity and elevated CO2 are poorly understood. This study examines the effects of long-term as well as short-term growth …
In a typical February, much of the United States is in the grip of cold winter weather - not this year. Record-high temperatures have been recorded across much of the country, and the warmth will continue for a while yet. The usual winter weather pattern involves cold Arctic being driven …
Study claims 50 percent chance of major chill before end of the century. For thousands of years, parts of northwestern Europe have enjoyed temperatures as much as 5 degrees Celsius above those of similar latitudes elsewhere in the northern hemisphere. Now, a study by a British and French team of …
Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of iron and chloride, exert a cooling effect on climate in several ways. This article aims firstly to examine all direct and indirect …
A simultaneous analysis of 13 years of remotely sensed data of land cover, fires, precipitation, and aerosols from the MODIS, TRMM, and MISR satellites and the AERONET network over Southeast Asia is performed, leading to a set of robust relationships between land-use change and fire being found on inter-annual and …
Reconstructing the history of tropical hydroclimates has been difficult, particularly for the Amazon basin—one of Earth’s major centres of deep atmospheric convection. For example, whether the Amazon basin was substantially drier or remained wet during glacial times has been controversial, largely because most study sites have been located on the …
Understanding the sources and evolution of aerosols is crucial for constraining the impacts that aerosols have on a global scale. An unanswered question in atmospheric science is the source and evolution of the Antarctic aerosol population. Original Source
Given that the population of the Sahel depends largely on rain-fed agriculture and transhumant livestock rearing, there is a growing concern about the future climate of the region as global warming may alter the availability of water resources. The lack of consensus on climate projections for West Africa results partly …
The Arctic continues to amaze. Hit by a second bout of extremely warm winter temperatures in recent days, the seasonal growth of floating sea ice has flattened out, just as it did when hit by similarly dramatic heat in November. The area of the Arctic Ocean covered by sea ice …
Researchers in the United States have found that local experiences and temperatures drive belief or non-belief of people in climate change. The study, published in the Journal of Proceedings of the National Academy of Sciences, found that Americans' belief that the earth is warming is related to the frequency of …
Major atmospheric-driven catastrophes, such as hurricanes and floods, may appear to be independent events when looked at historically. Yet it is well established in climate science that regional weather and climate conditions in one part of the world can have impacts on other parts. It is important for insurers and …
This paper provides an overview of the recent 2015-16 El Niño climate-related events and the subsequent lack of adequate response to the global drought. It proposes a fair shares approach to climate justice, thereby providing guidance for appropriate levels of humanitarian aid and boosting support for the most vulnerable. The …
Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanisms responsible for its enhancement, and implications for the growth rate of atmospheric CO2, remain unclear. Here using global carbon budget estimates, …
Globally averaged concentration of carbon dioxide in the atmosphere reached the symbolic and significant milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016 on the back of the very powerful El Niño event, according to the World Meteorological Organization's …
Airborne observations of greenhouse gases are a very useful reference for validation of satellite-based column-averaged dry air mole fraction data. However, since the aircraft data are available only up to about 9–13 km altitude, these profiles do not fully represent the depth of the atmosphere observed by satellites and therefore …
Anthropogenic aerosols are a key factor governing Earth’s climate, and play a central role in human-caused climate change. However, because of aerosols’ complex physical, optical, and dynamical properties, aerosols are one of the most uncertain aspects of climate modeling. Fortunately, aerosol measurement networks over the past few decades have led …
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 …
