According to the World Meteorological Organization’s (WMO) Provisional Statement on the State of Global Climate in 2012, released at the Doha Climate Change Conference on 28 November 2012, the years 2001-2011 were among the warmest on record and the first ten months of 2012 yielded above-average temperatures globally.

The contributions in this article examining some of the specific extreme weather or climate events of 2011 demonstrate the importance of understanding the interplay of natural climate variability and anthropogenic climate change on their occurrence.

This new report released by NOAA looks at extreme weather events that occurred in 2011 & finds 2011 among the 15 warmest since records began in late 1800. Shows human fingerprints identified in more than 2 dozen climate indicators examined by 378 scientists from 48 countries.

This recent annual survey on weather and climate change by WMO provides evidence that 2011 had the highest global mean surface temperature levels in a La Niña year. Highlighting a number of climate extremes, it provides evidences of the major impacts of one of the strongest La Niña events of the past 60 years.

Middle and South Andaman Islands have a fairly good fringing reef ecosystem, particularly the North Bay, Chidiyatappu, Ross and Havelock Islands. These reefs are dominated by Porites lutea, Porites nigrescens and Acropora spp. The appearance of corals or part of them in white (bleaching) is known to be associated with stress, which may be induced by sudden increase of sea-surface temperature (SST).

Climate shift has at times been fingered as a culprit in triggering conflict, fuelling for instance the 1789 French Revolution by wrecking harvests and driving hungry peasants to the city.

The weather pattern known as La Nina, blamed for floods in Australia and drought in parts of Latin America, is expected to persist through the first quarter of 2011, the World Meteorological Organization said on Tuesday.

La Nina, which cools the Pacific Ocean, could possibly even continue into April or early May, further affecting weather around the globe, the United Nations agency said in its

The World Meteorological Organization (WMO) has published a brochure titled "Weather Extremes in a Changing Climate: Hindsight on Foresight," which describes extreme events that have occurred between 2001 and 2010.  In addition to describing the examples of recent weather extremes, the brochure provides a map of extreme events over the decade and explores whether observed facts a

A SECOND straight poor summer monsoon is unlikely, India Meteorological Department (IMD) chief said ahead of an official forecast for the rains that are crucial to the economy of the world

India would have good summer monsoon this year is the unambiguous forecast statement coming in latest from the Tokyo-based Research Institute for Global Change (RIGC). This is based on the premise that the current El Nino with major warming in the central Pacific would end soon in the following months, says Dr Jing-Jia Luo, Senior Scientist at the RIGC.
