WMO: 2015 likely to be Warmest on Record, 2011-2015 Warmest Five Year Period
25 November 2015

Climate Change Breaches Symbolic Thresholds, Fuels Extreme Weather

Geneva 25 November 2015 (WMO) The global average surface temperature in 2015 is likely to be the warmest on record and to reach the symbolic and significant milestone of 1° Celsius above the pre-industrial era. This is due to a combination of a strong El Niño and human-induced global warming, according to the World Meteorological Organization (WMO).

The years 2011-2015 have been the warmest five-year period on record, with many extreme weather events - especially heatwaves - influenced by climate change, according to a WMO five-year analysis.

Haiti's new hydromet service takes shape
17 November 2015

The first stone of a new headquarters for Haiti's national meteorological and hydrological service has been laid, as part of a WMO programme to improve weather and climate services and increase disaster resilience in the Caribbean nation.

Full construction of the building, which will  be resistant to earthquakes and hurricanes, is scheduled to begin in early January 2016 and be finished by September. 

El Niño Expected to Strengthen Further: High Impacts, Unprecedented Preparation
16 November 2015

A mature and strong El Niño event, which is contributing to  extreme weather patterns, is expected to strengthen further by the end of the year, according to the latest Update from the World Meteorological Organization.

Peak three-month average surface water temperatures in the east-central tropical Pacific Ocean will exceed 2 degrees Celsius above normal, placing this El Niño event among the three strongest since 1950. (Strong previous El Niños were in 1972-73, 1982-83 and 1997-98).


Greenhouse Gas Concentrations Hit Yet Another Record
9 November 2015

Interaction between CO2 and water vapour amplifies warming

Geneva 9 November 2015 (WMO) The amount of greenhouse gases in the atmosphere reached yet another new record high in 2014, continuing a relentless rise which is fuelling climate change and will make the planet more dangerous and inhospitable for future generations.

The World Meteorological Organization’s Greenhouse Gas Bulletin says that between 1990 and 2014 there was a 36% increase in radiative forcing – the warming effect on our climate – because of long-lived greenhouse gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from industrial, agricultural and domestic activities.

New Report on Extreme Events
6 November 2015

Human activities, such as greenhouse gas emissions and land use, influenced specific extreme weather and climate events in 2014, including tropical cyclones in the central Pacific, heavy rainfall in Europe, drought in East Africa, and stifling heat waves in Australia, Asia, and South America, according to a new report released today. The report, "Explaining Extreme Events of 2014 from a Climate Perspective" published by the Bulletin of the American Meteorological Society, addresses the natural and human causes of individual extreme events from around the world in 2014, including Antarctica. NOAA scientists served as three of the five lead editors on the report.

Workshop on air pollution and agriculture
5 November 2015

Air pollution has an impact on agriculture and agriculture contributes to air pollution and greenhouse gas emissions. A group of experts in the field of atmospheric chemistry and agricultural meteorology discussed how to better measure theses emissions and impacts during an International Workshop held in Pune, India from 2-4 November 2015.  The workshop specially examined the impacts of atmospheric chemistry which includes air pollution on agricultural production, the impacts of agriculture on the atmospheric composition including greenhouse gases, biomass burning, reactive gases and aerosols.

Africa/Middle East meeting on sand and dust storms
5 November 2015

The first Africa / Middle East Expert Meeting and Workshop on the health impact of airborne dust has been held in Amman, Jordan, 2-5 November 2015 to assess the state of knowledge and encourage countries' actions with regard to impacts of airborne dust on public health in the region.

The Expert Meeting and Workshop will promote active communication among dust-related service providers, African/Middle-Eastern national meteorological and hydrological services and relevant national and international environment, air-quality and public health agencies.


International Conference on El Niño
3 November 2015

One of the strongest El Niño events ever measured is now underway. It is already causing droughts and flooding in different parts of the world, and affecting food production, water availability, public health and energy supplies in a number of countries.

The last major El Niño occurred in 1997/98, wreaking widespread havoc and erasing years of development gains. The world is much better prepared for this year’s El Niño, but the socio-economic shocks will still be profound.

In an effort to increase scientific understanding of this event and help boost resilience, a high-level El Niño conference will take place on Nov. 17 and 18, 2015. It is jointly organized by the International Research Institute for Climate and Society (IRI), the World Meteorological Organization (WMO), the U.S. Agency for International Development and the U.S. National Oceanic and Atmospheric Administration.


Cyclone Chapala hits Yemen
30 October 2015

A very rare and potentially high-impact tropical cyclone called Chapala made landfall in Yemen on 3 November.

WMO’s Regional Specialized Meteorological Centre, based in New Delhi, said that Chapala made landfall as a very severe cyclonic storm between 0100 and 0200 GMT, southwest of Ryan and near the port of Mukalla in Yemen. It had maximum sustained surface windspeed of 120-130 kilometers per hour gusting to 145 kph.

It then continued to move northwestwards, weakened into a severe cyclonic storm. Now that it has hit rugged terrain and dry air, Chapala It is forecast to weaken into a cyclonic storm and susbsequently into a depression.

Large Antarctic Ozone Hole Observed
29 October 2015

The surface area of the 2015 Antarctic ozone hole is among the largest observed, according to a new Bulletin from the World Meteorological Organization (WMO). This is because of colder than usual high-altitude (stratospheric) meteorological conditions. WMO stressed that the temperature conditions in the Antarctic stratosphere vary from year to year, so that in some years the ozone hole is relatively small and in other years relatively large. Overall, however, this does not reverse the projected long-term recovery in the coming decades.

On 2  October the ozone hole reached its maximum extent this year with an area of 28.2 million km2. This is the largest ozone hole area ever measured on this specific date according to the data record from NASA. Since 2 October the ozone hole area calculated by NASA has been larger than any other ozone holes for those dates. Averaged over the 30 consecutive days with largest area, the number is 26.9 million km2. This is the third largest observed after the record-breaking ozone holes of 2000 and 2006. 

"This shows us that the ozone hole problem is still with us and we need to remain vigilant. But there is no reason for undue alarm,” said Geir Braathen, a senior scientist in WMO’s Atmospheric and Environment Research Division.
