But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long deep freeze» — but rather a short - time span where human - caused warming might be partly offset by ocean cycles, staying at current record levels, but then followed by «accelerated» warming where you catch up to the long - term human - caused trend.

The climate scientists behind the report are less ready, however, to predict what the specific impacts of global warming will look like in the coming decades, meaning it won't be very useful for regional planners.

Truncating down to 1950 has yet another benefit: it shows that if we ignore the temperature data beyond 1970 (since we're using 1950 - 1970 temperature data to avoid end effects) and find the best fit using only HadCRUT3 up to 1970, we predict the next four decades of temperature remarkably well, even predicting the relatively flat temperature for 2000 - 2010, which the model shows is entirely attributable to SOL and has nothing to do with a cessation of long - term global warming.
