Climate change is already affecting us now, with severe implications for how we deal with global hunger. We see the impacts of climate change through increasing trends in the number and severity of droughts, wildfires, floods, hurricanes and other weather disasters, as well as slow-onset effects like sea level rise.
Changing climates are making it harder for farmers to predict crop seasons. This is particularly problematic for farmers in developing countries, who are dependent on rain-fed agriculture and lack the capacity and resources to adapt.
As the world begins to feel the impacts of a changing climate, we will inevitably need to spend money to adapt. People in developing countries had little or nothing to do with creating the climate crisis, but they will be affected the most. Thus, industrialized countries like the U.S. have a responsibility to provide funding to help these people deal with the impacts of climate change. There are a variety of ideas out there for how to do this, but none have been implemented yet.
The money we raise to deal with climate change can come either from public sources (through government spending and grants) or private sources (through corporate investment and lending).
