L'Institut de Recherche pour le Développement met « le climat sous surveillance » Open_resource by SUEZ À quelques semaines de la COP21, les opérations de sensibilisation aux enjeux climatiques se multiplient. Se distinguant par l’originalité de son approche, l’Institut de Recherche pour le Développement (IRD) , un organisme ayant pour but de contribuer au développement social, économique et culturel des pays du Sud, lance sa campagne : « Le climat sous surveillance ». C’est en s’amusant que l’on s’intéresse le plus et que l’on retient le mieux. C’est le credo de l’IRD, qui a lancé en octobre « Le climat sous surveillance », une opération de sensibilisation destinée aux scolaires et au grand public. Avec cette campagne, l’organisme entend initier le dialogue, via des forums et les réseaux sociaux, entre le grand public et ses chercheurs et faire découvrir les effets du dérèglement climatique sur différents types d’environnements. Cette campagne de sensibilisation ne se déploie pas que sur le Web.

Low-income countries will remain on the frontline of human-induced climate change over the next century, experiencing gradual sea-level rises, stronger cyclones, warmer days and nights, more unpredictable rains, and larger and longer heatwaves, according to the most thorough assessment of the issue yet.
The last major UN assessment, in 2007, predicted runaway temperature rises of 6C or more by the end of the century. That is now thought unlikely by scientists, but average land and sea temperatures are expected to continue rising throughout this century, possibly reaching 4C above present levels – enough to devastate crops and make life in many cities unbearably hot. As temperatures climb and oceans warm, tropical and subtropical regions will face sharp changes in annual rainfall, says the Intergovernmental Panel on Climate Change (IPCC) report, released on Thursday in Stockholm before online publication on 30 September.
Scientists have also lowered projections of sea-level rises. Climate change and poverty. In an ever-progressing world which withholds an increasing demand for energy, it is difficult to avoid climate change and its impacts on societies both locally and globally. Climate change affects social development factors, such as, poverty, infrastructure, technology, security, and economics across the globe. The interrelation between climate change and social vulnerability and inequality is evident, particularly in impoverished communities. Energy development and policy alteration could adjust the severity of climate change impacts; this is being tested now, as renewable energies develop.
Overview The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report projects that there is likely to be at least a 0.4-1.6 Celsius increase in global mean surface temperature by the period of 2046-2065 and likely a sea level rise of 0.17-0.32 meters by this time due to recent trends relative to 1986-2005 (IPCC 2013). Social Development Factors Poverty Security The Inequality of Climate Change. Typhoon Haiyan has left an estimated 10,000 dead and hundreds of thousands homeless in the Philippines. And it has once again underscored for many development experts a cruel truth about climate change: It will hit the world’s poorest the hardest.
“No nation will be immune to the impacts of climate change,” said a major World Bank report on the issue last year. “However, the distribution of impacts is likely to be inherently unequal and tilted against many of the world’s poorest regions, which have the least economic, institutional, scientific and technical capacity to cope and adapt.” That is the firmly established view of numerous national governments, development and aid groups and the United Nations as well. The reason is twofold. But poorer, lower-latitude regions are expected to face desertification and more-intense storms. Droughts are also expected to increase significantly in lower-latitude areas, including in Africa and the Middle East.
Desertification vulnerability. The Rising Cost of Natural Hazards : Feature Articles. Global warming could affect storm formation by decreasing the temperature difference between the poles and the equator. That temperature difference fuels the mid-latitude storms affect the Earth’s most populated regions. Warmer temperatures could increase the amount of water vapor that enters the atmosphere. The result is a hotter, more humid environment. At the equator, where conditions are already hot and humid, the change isn’t expected to be large. At the poles, however, the air is cold and dry; a little extra heat and water vapor could raise temperatures greatly. But even as a warming climate might decrease the overall number of storms that form, it could increase the number of intense storms.
The one way in which global warming could impact hurricanes is by making them more intense.
