No. 997 - Scientists urge more frequent updates of 30-year climate baselines to keep pace with rapid climate change

Heidelberg, Germany, 9 July 2014 – The WMO Commission for Climatology has recommended that governments adopt a two-tier approach to updating the 30-year baselines that scientists and meteorological services use to monitor the weather and climate and make comparisons to past conditions.

Because the climate varies naturally from year to year, climatologists use standard 30-year averages of temperatures, precipitation and other variables to put, for example, the magnitude of a current heatwave or rainstorm into historical context. These 30-year historical periods are called “climate normals” and can be calculated at the local, national or global levels. >> More

No. 996 - WMO and WHO Establish Joint Office for Climate and Health

Geneva, 8 July 2014 (WHO/WMO) - The World Health Organization and the World Meteorological Organization have joined forces to tackle the increasing risks to human health posed by weather and climate hazards such as extreme temperatures, floods, droughts and tropical cyclones.

A new WHO/WMO Climate and Health office has been established under the auspices of the Global Framework for Climate Services (GFCS) to promote the coordinated development and use of climate services to improve public health. It will increase awareness, build capacity, and connect meteorological services with experts in the health sector in an active partnership for climate adaptation and risk management. >> More

No. 993 - WMO Update: Prepare for El Niño

Geneva, 26 June 2014 (WMO) - There is a 60% likelihood of an El Niño being fully established between June and August, increasing to 75-80% for the October to December period, according to an El Niño Update issued by the World Meteorological Organization (WMO). Based on advice from National Meteorological and Hydrological Services, many governments have already started preparing for the arrival of El Niño, which is associated with regional-scale drought and flood situations in different parts of the world and has a warming influence on global average surface temperatures.

El Niño is characterized by unusually warm ocean surface temperatures in the central and eastern tropical Pacific, coupled with typical atmospheric circulation patterns. It is a natural phenomenon with a recurring interval of 2-7 years and has a major impact on the climate around the world. The last El Niño was in 2009/2010. >> More


No. 992 - Upgrade for World Weather Information Service (WWIS)

User-friendly official forecasts in 10 languages

Geneva, 23 June 2014 (WMO) - The World Meteorological Organization’s (WMO) highly successful World Weather Information Service website has been revamped and upgraded to a more modern and user-friendly format.

Developed and operated by the Hong Kong Observatory (HKO) on behalf of the WMO, the website provides official weather forecasts for 1 719 cities around the world supplied by 133 WMO Members. It is available in ten languages: Arabic, Chinese, English, French, German, Italian, Polish, Portuguese, Russian and Spanish.

“The World Weather Information Service is the authoritative source of official forecasts from around the globe. It is an excellent example of international collaboration between meteorological services to better serve the public worldwide. National weather services operate standardized weather observing networks and follow the most rigorous forecasting procedures,” said WMO Secretary-General Michel Jarraud. >> More

No. 991 - CO2 concentrations top 400 parts per million throughout northern hemisphere

Geneva, 26 May 2014 (WMO) - For the first time, monthly concentrations of carbon dioxide (CO2) in the atmosphere topped 400 parts per million (ppm) in April throughout the northern hemisphere. This threshold is of symbolic and scientific significance and reinforces evidence that the burning of fossil fuels and other human activities are responsible for the continuing increase in heat-trapping greenhouse gases warming our planet.

All the northern hemisphere monitoring stations forming the World Meteorological Organization (WMO) Global Atmosphere Watch network reported record atmospheric CO2 concentrations during the seasonal maximum. This occurs early in the northern hemisphere spring before vegetation growth absorbs CO2.

Whilst the spring maximum values in the northern hemisphere have already crossed the 400 ppm level, the global annual average CO2 concentration is set to cross this threshold in 2015 or 2016. >> More

No. 990 - WMO Update Indicates Possible onset of El Nino Around Middle of Year

Geneva, 15 April 2014 (WMO) - Sub-surface water temperatures in the tropical Pacific have warmed to levels similar to the onset of an El Nino event, and climate models surveyed by WMO experts predict a steady warming of the tropical Pacific during the months ahead, according to the latest Update from the World Meteorological Organization. A majority of models indicate that an El Niño may develop around the middle of the year, but it is still too early to assess the strength of any such event.

El Niño is characterized by unusually warm ocean surface temperatures in the central and eastern tropical Pacific. It has a significant impact on climate in many parts of the world and has a warming influence on global temperatures. It is the opposite of the La Niña phenomenon, which is associated with cooling.

Since the second quarter of 2012, El Niño-Southern Oscillation (ENSO) indicators (e.g., tropical Pacific sea surface temperatures, sea level pressure, cloudiness and trade winds) have generally remained at neutral levels. This is expected to continue into the earlier part of the second quarter of 2014, according to the WMO Update. >> More

 

No. 989 - New IPCC report highlights effective actions for reducing greenhouse gases and the risks of global climate change

Berlin, 13 April 2014 – An Intergovernmental Panel on Climate Change (IPCC) report launched here today confirms that it is still possible to avoid the worst effects of climate change – but only if the international community takes urgent and ambitious actions to curb greenhouse gas emissions.

“Last year, the IPCC stated that limiting the warming caused by greenhouse gas emissions to a 2°C rise will require that our future emissions of carbon dioxide be dramatically lower than the total amount of all our past emissions. Today’s report on Mitigation of Climate Change presents what we need to do to meet this profound challenge,” said Michel Jarraud, Secretary General of the World Meteorological Organization, which, together with the UN Environment Programme, sponsors the IPCC. >> More

 

No. 988 - Cherrapunji, India, Holds New Record for 48-Hour Rainfall

GENEVA, 4 April 2014 (WMO) - A World Meteorological Organization (WMO) panel has concluded that Cherrapunji in India now holds the world record for two-day (48-hour) rainfall, with 2 493 millimeters (98.15 inches) recorded on 15–16 June 1995.

This rainfall total exceeds the previous world 48-hour rainfall record of 2 467mm (97.1”) associated with the passage of a tropical cyclone over the Indian Ocean island of La Réunion (France) in April 1958. La Réunion, which is frequently hit by tropic cyclones and receives large amounts of rainfall over its mountains, continues to hold the record for the most rainfall over periods of 12-hours and 24-hours (in 1966), as well as 72-hours and 96-hours (in 2007).

The WMO Commission of Climatology international panel of experts reached its decision following an in-depth investigation of the Cherrapunji rainfall event for it to be included in the WMO World Archive of Weather and Climate Extremes, the official international listing of weather and climate extremes.  >> More



No. 987 - IPCC report on impacts, vulnerability and adaptation confirms the high human costs of climate change _ WMO urges governments to translate research findings into actionable information through climate services

Yokohama, 31 March 2014 – The IPCC’s Climate Change 2014: Impacts, Adaptation and Vulnerability, a comprehensive assessment report by leading scientists launched here today, offers policymakers and the general public a wealth of information about how climate change will affect the lives of current and future generations – and what governments can do to adapt and reduce vulnerabilities.

“Over the coming decades, climate change will have mostly negative impacts on cities and infrastructure, migration and security, ecosystems and species, crops and food security, public health, water supplies, and much more. We will see more ocean acidification and extreme droughts, floods and heatwaves. The poor and vulnerable will be most affected,” said Michel Jarraud, Secretary-General of the World Meteorological Organization (WMO) which, together with the UN Environment Programme, established the IPCC in 1988. >> More

No. 985 - WMO Annual Climate Statement Highlights Extreme Events

Geneva, 24 March 2014 – The year 2013 once again demonstrated the dramatic impact of droughts, heat waves, floods and tropical cyclones on people and property in all parts of the planet, according to the World Meteorological Organization’s Annual Statement on the Status of the Climate. The report confirmed that 2013 tied with 2007 as the sixth warmest on record, continuing the long-term global warming trend. It provided a snapshot of regional and national temperatures and extreme events as well as details of ice cover, ocean warming, sea level rise and greenhouse gas concentrations – all inter-related and consistent indicators of our changing climate.

Thirteen of the fourteen warmest years on record have all occurred in the 21st century, and each of the last three decades has been warmer than the previous one, culminating with 2001-2010 as the warmest decade on record. The average global land and ocean surface temperature in 2013 was 14.5°C (58.1°F) –  0.50°C (0.90°F) above the 1961–1990 average and 0.03°C (0.05°F) higher than the 2001–2010 decadal average. Temperatures in many parts of the southern hemisphere were especially warm, with Australia having its hottest year on record and Argentina its second hottest. >> More

No. 983 - WMO: 2013 Among Top Ten Warmest on Record

The year 2013 was among the top ten warmest years since modern records began in 1850, according to the World Meteorological Organization (WMO). It tied with 2007 as the sixth warmest year, with a global land and ocean surface temperature that was 0.50°C (0.90°F) above the 1961–1990 average and 0.03°C (0.05°F) higher than the most recent 2001–2010 decadal average.

Thirteen of the 14 warmest years on record have all occurred in the 21st century. The warmest years on record are 2010 and 2005, with global temperatures about 0.55 °C above the long term average, followed by 1998, which also had an exceptionally strong El Niño event.

Warming El Niño events and cooling La Niña events are major drivers of the natural variability in our climate. Neither condition was present during 2013, which was warmer than 2011 or 2012, when La Niña had a cooling influence. 2013 was among the four warmest ENSO-neutral (neither El Niño nor La Niña) years on record. >> More

Update El Niño / La Niña

Geneva, 30 January 2014 (WMO) -The tropical Pacific continues to be ENSO-neutral (neither El Niño nor La Niña). Model forecasts and expert opinion suggest that neutral conditions are likely to continue into the second quarter of 2014. Current model outlooks further suggest an enhanced possibility of the development of a weak El Niño around the middle of 2014, with approximately equal chances for neutral or weak El Niño. However, models tend to have reduced skill when forecasting through the March-May period. National Meteorological and Hydrological Services and other agencies will continue to monitor the conditions over the Pacific and assess the most likely state of the climate through the first half of 2014.

Since the second quarter of 2012 El Niño-Southern Oscillation (ENSO) indicators in the tropical Pacific (e.g., tropical Pacific sea surface temperatures, sea level pressure, cloudiness and trade winds) have generally been at neutral levels, indicating that neither El Niño nor La Niña conditions have been present. >> More
