This joint WFP and Action Against Hunger publication presents the impacts of El Niño in LAC, highlighting the emergency response and resilience activities taken to mitigate the effect of climate shocks in the region. The publication underscores the significance of adequate anticipation, preparedness, and response to climate emergencies in LAC. …
Establishing a direct link between climate change and fluctuations in animal populations through long-term monitoring is difficult given the paucity of baseline data. We hypothesized that social wasps are sensitive to climatic variations, and thus studied the impact of ENSO events on social wasp populations in French Guiana. We noted …
The Indian subcontinent witnessed a severe monsoon drought in the year 2009. India as a whole received 77% of its long period average during summer monsoon season (1 June to 30 September) of 2009, which is the third highest deficient all India monsoon season rainfall year during the period 1901–2009. …
There are many challenges involved in understanding climate variations in the tropics, and how the Pacific climate might change with global warming. One study offers a surprising perspective on the mechanisms involved.
he stable isotope ratios of atmospheric CO2 (18O/16O and 13C/12C) have been monitored since 1977 to improve our understanding of the global carbon cycle, because biosphere–atmosphere exchange fluxes affect the different atomic masses in a measurable way. Interpreting the 18O/16O variability has proved difficult, however, because oxygen isotopes in CO2 …
Clouds only amplify climate change, says a Texas A&M; University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change. Andrew Dessler, a Texas A&M; atmospheric sciences professor considered one of the nation's experts on climate variations, says decades of data support …
Computer simulations of the weather workings of the entire planet will be able to make forecasts to within a few kilometers accuracy, helping predict the effects of deadly weather systems. But the world may have to wait 20 to 40 years' for such accurate information on weather events like El …
La Nina, a weather phenomenon typically linked to flooding in the Asia-Pacific, African drought and a more intense hurricane season over the Atlantic, could occur in a weak form this year, the World Meteorological Organization said Thursday. A borderline La Nina situation has developed in recent weeks in the tropical …
El Nino May Account For A Fifth Of Worldwide Violence During The Last 50 Years, Says Study Michael McCarthy Wars and civil conflicts are twice as likely to occur during years affected by the El Nino climate-warming phenomenon, a study suggests. The naturally recurring weather system, which boosts temperatures and …
The idea that climate influences the onset of wars is enticing, but controversial. A study now finds a convincing correlation between global climate and civil conflict in countries affected by the El Niño/Southern Oscillation.
It has been proposed that changes in global climate have been responsible for episodes of widespread violence and even the collapse of civilizations. Yet previous studies have not shown that violence can be attributed to the global climate, only that random weather events might be correlated with conflict in some …
The Climate Prediction Centre (CPC) of the US National Weather Services has officially switched its El Nino-La Nina alert system status to a ‘La Nina watch.' La Nina refers to the cooling of equatorial Pacific Ocean and shifts the warming pool of waters and storminess to the west, which has …
The India Meteorological Department (IMD) has forecast ‘below normal' rainfall for the country during the second half (August-September) of the current south-west monsoon season. This comes even as the first half (June-July) has turned out to be not so bad, with the monsoon showers being reasonably well spread, both in …
The primary goal of the annual State of the Climate collection of articles is to document the weather and climate events of the most recent calendar year and put them into accurate historical perspective, with a particular focus on unusual or anomalous events. This report states that year 2010 was …
For the first time, scientists have discovered mysterious deep seat jets of water which cause anomalies in wind, rainfall and sea temperature across the tropical Atlantic. Past research has shown that the oceans impact climate in a multitude of ways, most notably with the ocean-atmosphere phenomena known as El Nino …
The government on Tuesday forecast normal monsoon rains for the country in 2011, boosting prospects of the farm sector and giving respite to policymakers struggling to check rising inflation. Quantitatively, the overall rainfall is likely to be 98% of the long-period average with a 5% margin of error, minister for …
Coarse resolution palaeoclimate proxy evidence has suggested that the Pliocene warm period (PWP) between 3 million and 5 million years ago was characterized by permanent El Niño conditions in which the equatorial Pacific was uniformly warm, instead of having the modern-day 'cold tongue' extending westward from South America. New high-resolution …
Under the project 'Seasonal Prediction of the Indian Monsoon' (SPIM), the prediction of Indian summer monsoon rainfall by five atmospheric general circulation models (AGCMs) during 1985-2004 was assessed. The project was a collaborative effort of the coordinators and scientists from the different modelling groups across the country.
Last year tied for the hottest year on record, confirming a long-term warming trend which will continue unless greenhouse gas emissions are cut, the World Meteorological Organization (WMO) said on Thursday. The first 10 years of the millennium proved to be the hottest decade since records began in the 19th …
