impacts of climate change

• The poorest will be hit earliest and most
  severely. In many developing countries, even
  small amounts of warming will lead to declines in
  agricultural production because crops are already
  close to critical temperature thresholds.
• The human consequences will be most serious in
  sub-Saharan Africa
