Climate Change

Climate change is the variation in the Earth's global climate or in regional climates over time. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. These changes can be caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities.

In recent usage, especially in the context of environmental policy, the term "climate change" often refers to changes in modern climate (global warming).

Climate change is one of the most critical global challenges of our time. Recent events have emphatically demonstrated our growing vulnerability to climate change. Climate change impacts will range from affecting agriculture- further endangering food security-, sea-level rise and the accelerated erosion of coastal zones, increasing intensity of natural disasters, species extinction and the spread of vector-borne diseases.

	2007/2008 Human Development Report tackles climate change The report warns that the world should focus on the development impact of climate change, which could bring unprecedented reversals in poverty reduction, nutrition, health and education.
	Changement climatique et évènements hydrologiques extrêmes : quels liens ? Le changement climatique a-t-il des effets sur le régime hydrologique des cours d’eau en France ? C’est une des questions que s’est posé Benjamin Renard dans le cadre de sa thèse soutenue au Cemagref, à Lyon. Il a pour cela mené une étude statistique sur l’évolution des évènements hydrologiques extrêmes en France au cours des 50 dernières années. Diffi cile de discerner le rôle du climat dans les résultats obtenus. La lettre du CEMAGREF: N°78, Janvier 2007
