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 …
New research based on ocean models and near real-time data from autonomous gliders indicates that the "The Blob" and El Niño together strongly depressed productivity off the West Coast, with The Blob driving most of the impact. The research published in the journal Geophysical Research Letters by scientists from NOAA …
Soggy summers in Europe and the UK are heavily influenced by the track of Atlantic storms The UK is likely to continue to have soggy summers regardless of global warming according to a new study. Scientists say that greenhouse gases will cause a general rise in summer temperatures, over the …
One of the strongest El Niño events ever recorded has placed the lives of 26.5 million children at risk of malnutrition, water shortages and disease in ten countries in Eastern and Southern Africa, the United Nations Children's Fund (UNICEF) has reported. "Children face protection risks as families and communities move …
Sydney has just shivered through its coolest June day in 21 years although the worst of the cold spell is probably over for now. Sydney's maximum temperature for Monday reached just 11.7 degrees making it the coolest day for any month in 20 years, said Brett Dutschke, senior meteorologist with …
High precipitation quantiles tend to rise with air temperature, following the so-called Clausius–Clapeyron scaling. This CC-scaling relation breaks down, or even reverts, for very high temperatures. In our study, we verify this reversal using a 60-year period of summer data in Germany. One of the suggested meteorological explanations is limited …
Continuous measurements of atmospheric methane (CH4) mole fractions measured by NOAA's Global Greenhouse Gas Reference Network in Barrow, AK (BRW), show strong enhancements above background values when winds come from the land sector from July to December from 1986 to 2015, indicating that emissions from arctic tundra continue through autumn …
Carbon dioxide level in South Pole crosses 400 ppm for the first time in four million years: study The carbon dioxide levels surpassed 400 parts per million (ppm) at the South Pole for the first time in four million years, according to U.sS. scientists. The South Pole has shown the …
Atmospheric carbon dioxide (CO2) is for the first time expected to exceed 400 parts per million for 2016 as a result of an extra boost from El Nino, finds a new study. El Nino warms and dries tropical ecosystems, reduces their uptake of carbon as well as exacerbates forest fires. …
In this paper, we evaluate the performance of the chemical transport model ‘CHIMERE’ over large Indian region (4–37.5°N; 67–88.5°E) for multiple years (2006, 2007 and 2008) by comparing the model simulations with concurrent aerosol measurements from different locations. Model simulated nearsurface black carbon mass concentrations agreed satisfactorily with measurements at …
We present the measurements of cloud-base height variations over ARIES, Nainital (79.45°E, 29.37°N, 1958 m amsl) obtained from Vaisala Ceilometer, during the nearly year-long Ganges Valley Aerosol Experiment (GVAX). Original Source
The Indian summer monsoon rainfall had a threedecade long alternate dry and wet epochs during about 150 years from 1840 to 1989. The dry epochs resulted in frequent drought monsoons affecting agriculture, power generation and the overall economy of the country. A high percentage of severe cyclones in the Bay …
A U.S. government weather forecaster on Thursday maintained its projections for the La Nina weather phenomenon to take place in the Northern Hemisphere later this year, as El Nino conditions dissipated. The Climate Prediction Center (CPC), an agency of the National Weather Service, said in its monthly forecast La Nina …
Japan's weather bureau said on Friday there was a high possibility that a La Nina weather pattern would emerge during the country's summer, which runs from around June to August, and continue through autumn. The Japan Meteorological Agency also said the El Nino, which had emerged in summer 2014, has …
The chances of a La Nina weather event forming later in 2016 are 50 percent, the Australian Bureau of Meteorology (BOM) said on Tuesday, as the tropical Pacific Ocean continues to cool. The bureau had said in May that the strongest El Nino in nearly 20 years - which had …
Worldwide heavy oil and bitumen deposits amount to 9 trillion barrels of oil distributed in over 280 basins around the world, with Canada home to oil sands deposits of 1.7 trillion barrels. The global development of this resource and the increase in oil production from oil sands has caused environmental …
This assessment report summarises current scientific knowledge on transboundary air pollution issues within the UNECE region and describes the effectiveness of air pollution measures in addressing large-scale effects on forests and lakes as well as in protecting human health and preventing other air pollution effects, such as loss in biodiversity …

Several sites in Sydney have experienced their coldest May morning in 20 years, even as the city looks set to record its warmest autumn. Less than two weeks after well above average temperatures were recorded across the eastern states, Sydneysiders awoke to record cold weather and frost on Monday. Richmond …
Widespread haze layers usually cover China like low clouds, exerting marked influence on air quality and regional climate. With recent Collection 6 MODIS Deep Blue aerosol data in 2000–2015, we analyzed the trends of regional haze pollution and the corresponding influence of atmospheric circulation in China.

The Japan Meteorological Agency has announced its three-month forecast from the month of June until August. This summer, while sweltering temperatures will be experienced nationwide, western Japan, in particular, will be hit by an intense heat wave, the agency said. According to the agency, the El Nino phenomenon will cause …
