Where this applies, a temperature trend extracted from tree rings alone would not show any substantial warming.

These higher temperature trends have been attributed by some researchers to global warming.

Another example is the examination of temperature trends that are accompanied with the growth of urban centers.

By minimizing these abnormal temperature trends and others, ecological activity would likely be improved in the urban setting.

The focus of the new federal study was conflicting records of atmospheric temperature trends.

A temperature trend extracted from tree rings alone would not show any substantial warming.

He flashed a slide that showed temperature trends for the past 15,000 years.

Statistically the increasing temperature trends are most significant in the months of January, March, and April.

What really counts is the actual temperature trend, which tells a very different story.

Both of these make the overall temperature trends clear by limiting the ability of the variability in the underlying data to obscure it.
