In the reports I've seen, the scientific community, include meteorologists, have built a consensus around the impacts of global warming. What they have predicted in their models is that as warming increases, we can expect to see a higher degree of variability in weather conditions, including an increase in intensity of storms. A great example of this is the warming of the Gulf of Mexico. When tropical storms enter the Gulf, they get supercharged by warm water closer to the coasts. If the water there continues to increase in temperature, that will increase the intensity of the storms to hurricane status. The frequency of tropical storms supercharging to hurricane status will also increase, as water temperatures stay at a higher level.

All sorts of wind patterns change. You'll see long periods of drought followed by rain storms that drop many more inches in a short period of time. You'll see cold regions such as Greenland become warm. You'll see coastal lands continue to erode and a higher cost of damages from raging coastal storms. It's all been predicted in the meteorological models. The reports I've seen also continue to claim that they are consistently UNDER-estimating the impacts. Meaning that they'll do forecasts and then find a year later that the weather pattern facts ended up being worse than they anticipated.

That is all to be expected as CO2 levels continue to accelerate and the earth's natural absorption capabilities from oceans to plants increasingly fail to absorb as much as we emit. It's a simple equation. Emissions minus sinks equal the rise in CO2 levels. That rise shows that the equation is net positive, getting worse daily, and continuing to accelerate.
