Sentences with phrase «long term temperature trends»

The problem is that most weather station records are not kept for monitoring long term temperature trends.

Anticipating that the influence of the aerosol forcing is strongest for longer term temperature trends in summer, application of the detection and attribution test to the latest observed 50 - y trend pattern of summer temperature yielded statistical consistency with the greenhouse gas - plus - aerosol simulation with respect to both the pattern and amplitude of the signal.

But all of the kerfuffle over the Mail story and the endless discussions over short and long term temperature trends hides what people are actually arguing about — what is likely to happen in the future, rather than what has happened in the past.

the 1.5 to 2 m observations of minimum temperatures that are used as part of the analysis to assess climate system heat changes (e.g., such as used to construct Figure SPM - 3 of Intergovernmental Panel on Climate Change [2007] and of Parker [2004, 2006] study) lead to a greater long term temperature trend than would be found if higher heights within the surface boundary layer were used.

But, unfortunately, most of these records were not meant for studying long term temperature trends, and so they are often affected by various non-climatic biases.
