Climate change is the defining issue of our time, because it affects nearly every aspect of human lives. Floods, droughts, heat waves and other types oi extreme weather reduce harvests, threaten the lives and livelihoods of those living on the margins, and(1)have a disproportionate impact on the extreme poor.
    Because many of the poorest people live off the land, they are more susceptible to the impacts of extreme weather conditions. Climate change is expected to lead to increased frequency and intensity of extreme weather events, such as storms and droughts. Extreme weather events can have devastating effects on subsistence farmers. While no one event can be attributed to climate change,(2)the East African drought of 2011 -2012 contributed to a famine in Somalia, which contributed to the deaths of an estimated quarter of a million people. In Nepal , Pakistan, Bangladesh and some parts of South and East Asia,the combination of flooding caused by unusually heavy rains, poverty and low levels of development regularly brings hunger and death.
