...with few exceptions, these include:

Recent historical emissions sometimes ‘mistaken’ or ‘massaged’
 Short-term emission growth seriously down played
 Peak year choice ‘Machiavellian’ & dangerously misleading
 Reduction rate universally dictated by economists
 Geoengineering widespread in low carbon scenarios
 Annex 1/non-Annex 1 emissions split neglected or hidden
 Assumptions about ‘Big’ technology naively optimistic
 (‘Net’ Costs meaningless with non-marginal mitigation & adaptation)

Collectively – they have a magician’s view of time & a linear view of problems ?

For 4°C global mean surface temperature
5°C - 6°C global land mean
… & increase °C on the hottest days of:
6°C - 8°C in China
8°C - 10°C in Central Europe
10°C -12°C in New York

In low latitudes 4°C gives
up to 40% reduction in maize & rice
as population heads towards 9 billion by 2050
