Not exact matches

... they caution that society should fully quantify direct and indirect GHG emissions associated with energy alternatives and associated consequences prior to making policy commitments that have long - term effects on global forests; for they ominously warn «there is a substantial risk of sacrificing forest integrity and sustainability for maintaining or even increasing energy production with no guarantee to mitigate climate change.»»

Niklas Höhne of NewClimate Institute said: «Over the last year, governments have made substantial steps in improving climate policies, and this has had a discernible effect on global emissions projections.

Heinrich events — abrupt periods of substantial iceberg discharge from the Northern Hemisphere ice sheets — occurred repeatedly throughout the last glacial period and had pronounced global effects on climate.

While there still is quite a bit of uncertainty surrounding the effects of the PDO on Earth's climate, the U.K. Met Office says that «decadal variability in the Pacific Ocean may have played a substantial role in the recent pause in global surface temperature rise.»

Thus if the two mid latitude jets move equatorward at the same time as the ITCZ moves closer to the equator the combined effect on global albedo and the amount of solar energy able to penetrate the oceans will be substantial and would dwarf the other proposed effects on albedo from changes in cosmic ray intensity generating changes in cloud totals as per Svensmark and from suggested changes caused in upper cloud quantities by changes in atmospheric chemistry involving ozone which various other climate sceptics propose.

Although the most advanced theoretical climate models still leave uncertainty, particularly about the sign and magnitudes of the effects, on GHG feedbacks, of some low - and high - clouds, a consensus began to develop that threats of resulting increases in global temperature — and the very large risks associated with their possible consequences — deserved substantial increase in attention.
