Hey Mike, the answer to that is "probably yes," but the change will be narrow at best. If you read the entire article, it states a 7 - 11 % increase by 2045. To be honest, this is worked out with a myriad of assumptions, the biggest one being an increase in precipitation in the logged areas, specifically the Northwest. That is a guess at best. There is every reason to believe that any change in climate that results in an increase in thermal energy in our atmosphere (global warming) will offer a relative increase in moisture in the air, and there by an increase in rain/snow. The real problem in forecasting like this is nobody knows where that rain will fall. To be honest, there will be areas in 40 years that are drier than today, we're already seeing that now. This has to do with the jetstream making mildly larger sweeps further north and south than it typically does, and forecasting an increase in overall precipitation 40 years from now based on that is pretty spotty.
I don't know what your position is on global warming, but here is an interesting experiment you can do to better visualize the situation. Take a small sauce pan, fill it 3/4 up with water, and put it on the stove at medium heat. Now set a meat thermometer in the water and watch. At some point, when the temperature gets up around 180+ you'll see tiny bubbles form on the bottom. As you approach 212 degrees F the bubbles will begin dislodging and going to the surface. Now keep heating, as the water reaches a rolliing boil, the temperature is still right around 212, and will continue to be until more than half the water has boiled away, after that you will start to see spikes in the temp above 212. This is because of the amount of heat, or BTU's it takes to turn one gram of water from liquid to gas. More of the water in the pan becomes vapor, but the temp only moves a tiny amount. We are seeing this tiny increase in the earths overall temps now, and we are seeing much more water vapor lofted into gaseous states, and forming stronger thunderstorms, more hurricanes, and more snowfall, but only in certain areas, some areas are becoming more aired. Our environment globally mimicks the pan of water, we have some water frozen, in the form of ice caps, some liquid, and some vapor, and by simply exchanging more liquid for vapor indicates more 'energy' is present in the atmosphere, there really isn't any arguing over that, but still we do. Take care Mike, Rudydoo
