What we can't really predict is the ecosystem response to the extra heat.
Sure we can. There will be increased precipitation (which we are starting to see) in places that were formerly arid. Growing seasons will lengthen above 45° northern latitude and below 45° southern latitude. We'll also see crops growing in places where they haven't been seen for the past thousand years.
We're not going to see Al Gore's apocalyptic 'super storms' but we are going to see more weather as there's more energy to power it. Cloud cover will increase and clear skies will become unusual.
Eventually that can lead to more snow cover and more reflected energy and then we'll see a corrective cooling trend.
To be followed by a warming trend.
In short, climate can be expected to do the same things it's done for eons and that is to oscillate.
