From my global warming post I would say that the long term, multi-billion year average temperature when the continents are not moving fast and genarally in a compact configuration is about 27 degrees celsius. A little over 14 degrees celsius than where we are at right now...
But to get that you have to have low riding, slow moving continents and vast, shallow inland seas to act as a massive heat sink. Also no continental masses at the poles. Give it another 20-35 million years and we will get back to the normal, balmy climate of the Cretaceous!!
Until then, highly variable and changeable weather, high levels of volcanic activity with sudden megavolcanic eruptions and extinction events followed by glacial periods. Partly cloudy. Mostly snow with some rain and sleet mixed in. Highs and lows to be extremely variable and expect sudden, 100,000 to 300,000 year cold snaps and miles thick glaciers on most continents and lots of exposed continental shelf.
Major asteroid impacts every 60 million years or so, in the 8-10 km in diameter range with many smaller ones more frequently.
Solar output to remain +/- 1-3% with some variability over the next 3 billion years or so. After that expect a sudden warming period and the planet Earth to be engulfed by the sun.
Prognosis: sell the planet as soon as possible as a 'fixer upper' and get the hell out of here.
Simon - Yes, this planet is a so-so 'starter home' but not really all that fit for long-term occupation. Even if we had the technology and energy to *fix* the problems, it just isn't worth it. Because once you have those you can leave the system.
