Sentences with phrase «giss trend»

However in the first decade which GISS forecasts, rather than backcasts, this opposite trend in signals emerges.

But models are not tuned to the trends in surface temperature, and as Gavin noted before (at least for the GISS model), the aerosol amounts are derived from simulations using emissions data and direct effects determined by changes in concentrations.

He says «Well when I look at it the GISS decadal, climate only, signal trend, matches the weather and climate decadal signal trend.

If it turns out that the choices made by CRU, GISS, NOAA fall on the «maximize historical trends» end of the scale, that will not help their perceived credibility for obvious reasons.

However, at least with NASA GISS, it would appear that there is no statistical basis as of yet to claim that the trend in warming has reversed itself, slowed or accelerated from what it was beginning in 1975.
