These changes make it harder for the poorest and most vulnerable people to grow and access enough nutritious food. By 2050, there could be an extra 25 million malnourished children under the age of five because of climate change.
And the cost of climate change only rises with each passing year. A recent Oxfam report found that, since global leaders last met to discuss climate change five years ago in Copenhagen, climate-related disasters have cost the world almost half a trillion dollars, making those years among the most expensive on record. More than 650 million people have been affected and more than 112,000 lives have been lost.
But this is not inevitable.
