Dopuszczalne progi niepewno艣ci procesu pomiarowego s膮 r贸偶ne w zale偶no艣ci od rodzaju stosowanego paliwa; paliwa gazowe i p艂ynne mierzy si臋 dok艂adniej ni偶 paliwa sta艂e. W ka偶dej z om贸wionych klas wyst臋puj膮 liczne wyj膮tki, kt贸re zale偶膮 od typu i cech paliwa, od sposob贸w dostawy (transportem wodnym, kolejowym, drogowym, ta艣moci膮giem, ruroci膮giem) oraz od cech i okoliczno艣ci w艂a艣ciwych dla danej instalacji; dopuszcza si臋 艂膮czenie metod bilansowania.

most of the observed warming

Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations. This is an advance since the TAR’s conclusion that “most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”. Discernible human influences now extend to other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes and wind patterns.

The time series shows the combined global temperature
The time series shows the combined global land and marine surface temperature record from 1850 to 2006. The year 2006 was sixth warmest on record, exceeded by 1998, 2005, 2003, 2002 and 2004. This time series is being compiled jointly by the Climatic Research Unit and the UK Met. Office Hadley Centre. The record is being continually up-dated and improved . This paper includes a new and more thorough assessment of errors, recognizing that these differ on annual and decadal timescales. Increased concentrations of greenhouse gases in the atmosphere due to human activities are most likely the underlying cause of warming in the 20th century.
