The map shows the frequency of flood events in US counties between 1996 and 2003. Identify the places that might benefit from building dams, levees, and diversion canals.

For those that don't know the states by name....

The bottom left options are your answers

Alaska; Yukon River

California; Salton Sea

Arizona; Gila River

New Mexico & Texas; Pecos River

Explanation:

Leaving aside the Hudson River in N.Y.  and the Susquehanna River in Pennsylvania (a relatively low frequency of floods) the 4 states that would benefit enormly from building dams etc. because of their high frequency of flood events) are California, Arizona, New Mexico and Texas.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
