There is high confidence that climate-related hazards, including both slow-onset shifts and extreme events, directly affect the poor through adverse impacts on livelihoods , including reductions and losses of agricultural yields, impacts on human health and food security, destruction of homes, and loss of income . One of the key factors that drives disproportionate impacts among poor households globally is lost agricultural income  . Also of concern are the impacts of climate hazards to human health, which is a primary resource that the poor rely on . There are only few robust global estimates of observed income losses to the poor that comprehensively account for all climate hazards; nevertheless, , estimating average impacts of climate change on incomes of the poor, found that across 92 developing countries, the poorest 40% of the population experienced losses that were 70% greater than the losses of people with average wealth.
