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 WMO Air Quality and Climate Bulletin reports annually on the state of air quality and its connections to climate change, reflecting on the geographical distribution of and changes in the levels of traditional pollutants. The present edition of the WMO Air Quality and Climate Bulletin provides an update on …
COVID-19 did not slow the relentless advance of climate change. There is no sign that we are growing back greener, as carbon dioxide emissions are rapidly recovering after a temporary blip due to the economic slowdown and are nowhere close to reduction targets. Greenhouse gas concentrations in the atmosphere continue …
COVID-19 lockdowns brought rapid and “unprecedented” improvements in air quality in some parts of the world - but not enough to halt climate change caused by global warming said the World Meteorological Organization (WMO)'s Air Quality and Climate Bulletin The COVID-19 lockdown and travel restrictions led to a dramatic short-lived …
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 National Centers for Environmental Information, is based on contributions from scientists from …
The Secretariat of the Pacific Regional Environment Programme (SPREP) has developed a State of the Environment (SoE) report for the Pacific islands, the first of its kind. It reveals areas of progress as a result of conservation efforts, as well outstanding and newly emerging issues. The report focuses on 31 …
The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of greenhouse gases which are trapping heat in the atmosphere, increasing temperatures and driving more extreme weather, ice melt, sea-level rise and ocean acidification, according to the World Meteorological Organization (WMO). The lockdown has cut emissions of …
Each year, an estimated two billion tonnes of dust is raised into the atmosphere. According to the report, Impacts of Sand and Dust Storms on Oceans: A Scientific Environmental Assessment for Policy Makers, even the smallest elements can have substantive effects on ecosystem functioning – and on the Earth system, …
The pre-monsoon cyclone Viyaru in the Bay of Bengal during May 2013 traversed a long track from 5°N to 22°N over 7 days with basin-wide response, which was well captured by the time series observations of OMNI buoy network along with satellite data. Original Source
This book discusses the impact of human-induced global climate change on the regional climate and monsoons of the Indian subcontinent, adjoining Indian Ocean and the Himalayas. It documents the regional climate change projections based on the climate models used in the IPCC Fifth Assessment Report (AR5) and climate change modeling …
Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …
During austral summer (DJF) 2017/18, the New Zealand region experienced an unprecedented coupled ocean-atmosphere heatwave, covering an area of 4 million km2. Regional average air temperature anomalies over land were +2.2 °C, and sea surface temperature anomalies reached +3.7 °C in the eastern Tasman Sea. This paper discusses the event, …
Aerosol pH is difficult to measure directly but can be calculated if the chemical composition is known with sufficient accuracy and precision to calculate the aerosol water content and the H+ concentration through ion balance. In practical terms, simultaneous measurements of at least one semi-volatile constitute, e.g. NH3 or HNO3, …
The purpose of this study is to propose the Bayesian Network (BN) model to estimate flood peak from Atmospheric Ensemble Forecasts (AEFs). The Weather Research and Forecasting model was used to simulate historic storms using five cumulus parameterization schemes. The BN model was trained to forecast flood peak from AEFs. …
The northern part of India, adjoining the Himalaya, is considered as one of the global hot spots of pollution because of various natural and anthropogenic factors. Throughout the year, the region is affected by pollution from various sources like dust, biomass burning, industrial and vehicular pollution, and myriad other anthropogenic …
The Earth this year may witness one of the largest increase in atmospheric carbon dioxide in over six decades of record keeping, scientists say. The forecast by researchers from the UK Met Office and University of Exeter is based on a combination of factors including rising anthropogenic emissions and a …
GENEVA: Switching from beef to alternative proteins could save millions of lives and dramatically slash greenhouse gas emissions, the World Economic Forum said Thursday. New research conducted by the Oxford Martin School for WEF showed that efforts to replace meat and especially beef could provide huge benefits for human health …
The Sun’s activity cycle governs the radiation, particle and magnetic flux in the heliosphere creating hazardous space weather. Decadal-scale variations define space climate and force the Earth’s atmosphere. However, predicting the solar cycle is challenging. Current understanding indicates a short window for prediction best achieved at previous cycle minima. Utilizing …
Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization (WMO). There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather. The WMO Greenhouse Gas …
Recent studies note a significant increase in highpressure blocking over the Greenland region (Greenland Blocking Index, GBI) in summer since the 1990s. Such a general circulation change, indicated by a negative trend in the North Atlantic Oscillation (NAO) index, is generally highlighted as a major driver of recent surface melt …
