Sentences with phrase «global warming signal»

Our system predicts that internal variability will partially offset the anthropogenic global warming signal for the next few years.

In short, those arguing that global warming has stopped are missing the forest for the trees, focusing on short - term noise while ignoring the long - term global warming signal.

And the sea surface temperature and ocean heat content data do not support the existence of a human - induced global warming signal.

So this change in upper atmospheric behavior can be considered part of the «fingerprint» of the expected global warming signal in the climate system.»

Closer to the poles the emergence of climate change in the temperature record appeared later but by the period 1980 - 2000 the temperature record in most regions of the world were showing clear global warming signals.

However, Foster and Rahmstorf (2011) found that when we filter out the short - term effects of the El Niño Southern Oscillation (ENSO) and volcanic and solar activity, the underlying global warming signal has remained remarkably steady.

«Does the current global warming signal reflect a natural cycle»... We found 342 natural warming events (NWEs) corresponding to this definition, distributed over the past 250,000 years....

The point being made is that, without regard for the accuracy or precision of the instrumental record, you can still replicate the 20th - century global warming signal using only a subset of the data.

What Tamino did was multi variable regression to account for natural effects on the global average temperature to find what he called the real global warming signal.

Foster and Rahmstorf (2011) have published a paper in Environmental Research Letters seeking to extract the human - caused global warming signal from the global surface temperature and lower troposphere temperature data.

In other words natural variability dominates the observed record making it impossible to detect any human - caused global warming signal even if one were to exist (which there is no proof of).

We recently published a study in Scientific Reports titled Comparing the model - simulated global warming signal to observations using empirical estimates of unforced noise.

You'll note, for example, a heavy focus on developed countries, with one study of East African drought and one more of flooding rains in China (neither of which found a strong global warming signal) being the exceptions.

Because global warming signals are amplified in high - latitude regions, the potential for permafrost thawing and consequent greenhouse gas releases is thus large.

Jeremy Mathis, director of NOAA's Arctic Research Program, said the report highlights the clear and pronounced global warming signal in the Arctic and its effects cascading throughout the environment, like the spread of parasitic diseases in Arctic animals.

The first paper, Smith et al. (2007), predicted «that internal variability will partially offset the anthropogenic global warming signal for the next few years.

This is the point of Keenlyside 2008 and is echoed by the Hadley Centre who predicted internal variability will partiallyoffset the anthropogenic global warming signal for the nextfew years (Smith 2007).

«Our study shows that large - scale upper - ocean temperature changes provide a good way to distinguish decade - long natural ocean signals from longer - term global warming signals,» said Nieves.

One of the few exceptions to this clear global warming signal was found in large parts of the continental United States, particularly on the Eastern coast and up through the central states.

Later extreme temperature events showed a global warming signal.

Note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

Warm records are set through the 1930s and 40s, with a long stretch of no records until the 1980s, when the global warming signal firmly emerges from the noise of natural variation.
