Have Floods Changed with Increasing CO2 Levels?

Only one of four large regions of the United States showed a significant relationship between carbon dioxide (CO2) in the atmosphere and the size of floods over the last 100 years. This was in the southwestern region, where floods have become smaller as CO2 has increased. This does not mean that no strong relationship between flooding and greenhouse gases will emerge in the future. An increase in flood magnitudes remains one of the most anticipated impacts of climate change, and land and water resource managers are asking questions about how to estimate future flood risks and develop effective flood mitigation strategies for the future.

Some areas will experience more flooding, others less. Weather patterns will shift, and shift greatly if the thermosaline flows change. The absence of ice in the North Polar Sea could cause a major change in the flow of the Gulf Stream.
