Greenhouse Gas bulletin: the state of greenhouse gases in the atmosphere based on global observations through 2022

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 …

Peru bows out of 2016 Dakar Rally due to 'El Nino'

Peru Monday announced it is withdrawing as host of the 2016 Dakar Rally "due to concerns about the El Nino weather phenomenon," state news agency Andina reported. Peru's Ministry of Foreign Trade and Tourism issued a statement saying the government was cancelling its participation in both the 2015 Desafio Inca …

Kenya: El Nino 'Won't Be As Bad' as 1997

The weatherman confirms a big El Nino will hit Kenya but says it is unlikely to unleash the fury and destruction of 1997. Meteorological services director James Kongoti yesterday said there is a greater than 90 per cent chance El Nino will continue through to the short rains. He said …

Observations of atmospheric mercury in China: a critical review

China presently contributes the largest amount of anthropogenic mercury (Hg) emission into the atmosphere in the world. Over the past decade, numerous studies have been conducted to characterize the concentration and forms of atmospheric Hg in China, which provide insights into the spatial and temporal distributions of atmospheric Hg through …

Methane emission bursts from permafrost environments during autumn freeze-in: New insights from ground-penetrating radar

Large amounts of methane (CH4) are known to be emitted from permafrost environments during the autumn freeze-in, but the specific soil conditions leading up to these bursts are unclear. Therefore, we used an ultrawide band ground-penetrating radar in Northeast Greenland in autumn 2009 to estimate the volumetric composition inside the …

Significant increase of aerosol number concentrations in air masses crossing a densely trafficked sea area

In this study, we evaluated 10 months data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden), Utö (upwind, Finland), and Preila (downwind, Lithuania). Differences in aerosol particle number size distributions between the upwind …

The possible role of local air pollution in climate change in West Africa

The climate of West Africa is characterized by a sensitive monsoon system that is associated with marked natural precipitation variability. This region has been and is projected to be subject to substantial global and regional-scale changes including greenhouse-gas-induced warming and sea-level rise, land-use and land-cover change, and substantial biomass burning. …

Abrupt recent trend changes in atmospheric nitrogen dioxide over the Middle East

Nitrogen oxides, released from fossil fuel use and other combustion processes, affect air quality and climate. From the mid-1990s onward, nitrogen dioxide (NO2) has been monitored from space, and since 2004 with relatively high spatial resolution by the Ozone Monitoring Instrument. Strong upward NO2 trends have been observed over South …

July melted global temperature records, setting up 2015 as hottest year

July smashed global records for warmth, beating all 1627 previous months since 1880, as a monster El Nino in the Pacific combined with background climate change, US scientists said. Last month, average sea and land surface temperatures across the planet were 16.61 degrees, beating the previous monthly record during the …

Seasonal characterization of submicron aerosol chemical composition and organic aerosol sources in the southeastern United States: Atlanta, Georgia and Look Rock, Tennessee

A yearlong near-real-time characterization of non-refractory submicron aerosol (NR-PM1) was conducted at an urban (Atlanta, Georgia) and rural (Look Rock, Tennessee) site in the southeastern US using the Aerodyne aerosol chemical speciation monitor (ACSM) collocated with established air-monitoring network measurements. Seasonal variations in organic aerosol (OA) and inorganic aerosol species …

East Africa: Worst El Nino in 60 Years on Way - Experts

One of the strongest and wettest El Ninos will soon pummel East Africa, bringing heavy rains, floods and malaria. The prospect of a record-breaking El Nino is worrying since the 1997 weather killed many people in Kenya, and left hundreds homeless. Scientists say the condition, experienced across the world, could …

El Nino nearly certain to last until at least end-2015: Australian weather bureau

An El Nino weather pattern has strengthened over the last two weeks, the Australian Bureau of Meteorology (BOM) said on Tuesday, with now only a "small chance" the event will be over by the end of this year. Tropical Pacific Ocean temperatures are well above El Nino thresholds, the Australian …

A 'Great Gozilla' El Nino in prospect, but forecasters remain wary of impacts

This year's El Nino weather pattern could be the most powerful on record, US forecasters said, while warning that the effects of the weather system are never certain. "We're predicting this El Nino could be among the strongest El Ninos in the historical record," said Mike Halpert, deputy director of …

Worst El Nino in 30 Years Hits South American Crops, Polls

The El Nino climatic phenomenon has hit South America’s southern cone with a vengeance in the past week, causing flooding and landslides that have damaged crops, cut off roads, disrupted copper mining and might even influence Argentina’s presidential elections. In Chile, six people have been killed, mostly due to mudslides, …

Another El Niño sign: Ocean temps hit highest level of the year

In another sign that El Niño is gaining strength and could soak California this winter, sea surface temperatures in the Pacific Ocean have increased to their highest level so far this year. That temperature increase — 3.4 degrees Fahrenheit above the average — was recorded Aug. 5 by the National …

El Nino plus 'the blob' may help Western drought

Both are phenomena associated with warm water in the Pacific that can separately impact weather. Now, the two combined are building hopes for a wet winter that could help pull the West out of protracted drought. "This is a little bit of an unprecedented situation," said Kelly Redmond, deputy director …

Namibia: Dark Days Loom for Farmers As Fears of El Niño Rise

Dark clouds are gathering on the horizon for Namibian farmers already grappling with a prolonged drought as forecasters predict 2015 could become the hottest year on record. In a worst-case scenario - after consecutive droughts - possibly the strongest ever El Niño heat waves predicted to hit parts of Southern …

A monster is coming! Forecasters warn El Nino is getting stronger and could cause 'mayhem' but say it will bring relief to drought-stricken California

Exceptionally warm water moving from the western Pacific Ocean towards South America has caused El Niño to get even stronger in recent weeks. In fact, scientists claim conditions in the Pacific are now as intense as they were in the summer of 1997, when a massive El Niño was brewing. …

El Niño Tests How Soft Commodities Weather the Storm

Investors in soft commodities are used to being slaves to the weather’s twists and turns. With prices now in a depression and the El Niño weather pattern looming, the forecast looks more unsettled than normal. The possibility that the Federal Reserve will raise interest rates later this year, coupled with …

Winter is not coming: how man-made climate change is wiping out seasonal temperature differences

Mankind may be responsible for something we long thought out of our control: the changing of the seasons, according to a new study by Chinese and Canadian scientists. For the first time, researchers have found evidence that man-made climate change has suppressed the natural fluctuation of seasonal temperatures in the …

RI prepares for worst as El Niño causes prolonged dry season

The government has confirmed that over 9,000 hectares (ha) of rice fields in six provinces have experienced harvest failure over the past few months as it warns that this year’s dry season has not yet reached its peak. Speaking to reporters on Saturday, the Public Works and Public Housing Ministry’s …
