Sentences with phrase «term air temperature trends»

For this to be true you would have to prove that minor long - term global air temperature variations drive ocean oscillations and that these ocean oscillations — at some later point — influence global long - term air temperature trends....

Not exact matches

And it finds that, while this winter's unusually strong Arctic Oscillation - which funnels cold northern air to the East Coast and pulls warm mid-latitude air up to the Arctic - is predicted as atmospheric carbon dioxide levels rise, seasonal temperature anomalies associated with it aren't enough to blunt long - term warming trends.

This animation shows how the same temperature data (green) that is used to determine the long - term global surface air warming trend of 0.16 °C per decade (red) can be used inappropriately to «cherrypick» short time periods that show a cooling trend simply because the endpoints are carefully chosen and the trend is dominated by short - term noise in the data (blue steps).

«We show that the climate over the 21st century can and likely will produce periods of a decade or two where the globally averaged surface air temperature shows no trend or even slight cooling in the presence of longer - term warming,» the paper says, adding that, «It is easy to «cherry pick» a period to reinforce a point of view.»

Although the rate of warming of surface air and lower troposphere temperatures appear to have slowed over the past few years, the same could be said at any virtually any point in time by cherrypicking short - term noise and ignoring the long - term trend (Figure 2).

This study, which was supported by the U.S. National Science Foundation, is the first to analyze long - term trends in rainfall and surface air temperature over a timescale of nearly an entire century, the study's lead author, Natalie Thomas, a doctoral candidate in atmospheric and oceanic science at the University of Maryland, told Live Science.

At the end of the day, the discussion about a single calendar year obscures the more important long - term trend of warming air temperatures, warming and acidifying oceans along with melting ice sheets, all of which are hallmarks of manmade global warming.

Long - term climate trends of surface air temperature should not be expected to have the same trends for light wind and stronger wind nights, even if the trends in the boundary layer heat fluxes were the same.

The strong influence of natural variability on surface air temperatures is the reason that climate researchers regularly point out that any record shorter than around 20 - 30 years is not useful for detecting long - term trends associated with anthropogenic warming.

«The global surface air temperature record of the last 150 years is characterized by a long ‐ term warming trend, with strong multidecadal variability superimposed.

In this study, we primarily investigate the reliability of the climatology (long - term mean of model simulation) of large - scale features of climate model ensembles, but we also consider the trend for surface air temperature where transient simulations are available (that is, for the coupled ocean — atmosphere models).

The Bureau's surface air temperature measurements for Australia compare well with the remotely sensed satellite record in terms of area - averaged variability and warming trends.

Easterling and Wehner (2009) showed that «the climate over the 21st century can and likely will produce periods of a decade or two where the globally averaged surface air temperature shows no trend or even slight cooling in the presence of longer - term warming.»
