A summary of current climate change findings and figures
There is a strong scientific consensus that the global climate is changing and that
human activity contributes significantly. This consensus is attested to by a joint statement
signed in 2005 by 11 of the world’s leading national science academies representing Brazil,
Canada, China, France, Germany, Italy, India, Japan, Russia, the United Kingdom and the United
States. Their statement confirmed the likelihood of human-induced climate change.1 Many other
science bodies have issued similar statements.
Most of the scientific debate on climate change takes place through articles that climate scientists
publish in peer-reviewed scientific journals. Peer review, while not perfect, is a highly effective
system for ensuring that journals only accept articles that meet a good standard of scientific rigor
and objectivity. Several surveys of the refereed literature on climate change science have
confirmed that virtually all published papers accept the fundamentals of human-induced climate
change. The peer-reviewed literature is assessed every few years by the WMO/UNEP
Intergovernmental Panel on Climate Change. >> Full text
Questions and answers on the Japan earthquake aftermath
What is WMO doing in response to the Japanese crisis?
The World Meteorological Organization has activated its Environmental Emergency Response mechanism and is providing the International Atomic Energy Agency (IAEA) with meteorological information as per agreement under the Joint Radiation Emergency Management Plan of the International Organization (IAEA EPR-JPLAN 2010). On behalf of WMO, the National Meteorological Service of Austria (ZAMG) is providing meteorological support to the IAEA Incident and Emergency Centre (IEC) in Vienna on a 24/7 basis, and the National Meteorological Service of Switzerland (MétéoSuisse), is providing meteorological support to WHO at Headquarters in Geneva. >> full text
LA NIÑA AND CURRENT EXTREME WEATHER: QUESTIONS AND ANSWERS
What is La Niña? La Niña, a Spanish term that literally translates to ”girl child”, is characterized by unusually cold ocean surface temperatures in the central and eastern tropical Pacific. It is the opposite of El Niño (“boy child”, traditionally used by Peruvians to refer to the Christ Child as the phenomenon was often observed around Christmas), which is characterized by unusually warm ocean surface temperatures. The two events are strongly coupled with changes in atmospheric pressure and the associated large-scale circulation patterns, and are considered to be the opposite phases of air-sea interactions over the region collectively referred to as “El Niño/Southern Oscillation (ENSO)”. They disrupt the normal patterns of tropical precipitation and atmospheric circulation, and have widespread impacts on climate in many parts of the world accompanied by the associated climate-related risks. >> full text
