In Iowa, 138 scientists and researchers looked at studies and agreed that our warming world already is costing Iowa families money.
So they have signed a statement that says if Iowans do some smart things now, future generations won't have to spend as much to fight the weather.
These researchers and scientists, who work at Iowa colleges and universities, picked out three things they want Iowans to know:
- In a little less than two generations, Iowa has begun having a lot more really hot days and warm nights than really cold days and nights.
- Yes, Iowa is in a drought because it hasn't rained, but there's something else that has made this drought (which no one saw coming) so unusual: temperatures have been much, much higher than what usually happens in a drought.
- More and more when it rains, it rains really hard in Iowa.
These three things were picked out because they're three things scientists have said would happen if global warming were to happen.
In other words, we don't have to wait 100 years to see what will happen if global warming occurs.
That's because it already is happening. The world is between 1 and 2 degrees warmer than it was about 100 years ago.
What scares scientists is that the world is getting hotter, faster than even 100 years ago.
So these researchers and scientists hope that Iowans, as global citizens, will become leaders, whether that means something as simple as being energy efficient or as complicated as converting to energy sources that generate fewer greenhouse gases.
