Climate Change, agriculture and miscellaneous

Now, when tropical storms impact the US we are suddenly talking about feet of rain instead of inches!  Tropical Storm Alberto is dragging gigatons of moisture in its wake and flash flooding is occurring from Florida into North Carolina and up the US east coast.  Agriculture does not work well in situations like this.  Most cultivated cropland is susceptible to erosion under the intense rainfall of these storms.  Climate change theory predicted this as one of the many weather effects driven by the increase of CO2 in the atmosphere.  Heavy soils especially are difficult to work or grow when inundated by heavy rainfall.  The lack of oxygen in saturated soils kills roots and crops.   Here on the NCR we haven't had extreme precipitation so far this year, but high water tables have prevented some soils from drying and has delayed planting.  Heavy rains at any time in the next month could be a disaster for some growers.   One my micro farm I have several different soil regimes and most of them are dry, but a single 5 inch or more event could drown several areas and make them unplantable for several weeks, effectively ending my growing season for several crops.  Has there been any admission from government sources regarding evidence of climate change?
