Sentences with phrase «natural variability of climate»

Because of the large natural variability of climate, scientists do not expect temperatures to rise consistently year after year.

Some external influences, such as changes in solar radiation and volcanism, occur naturally and contribute to the total natural variability of the climate system.

For instance, the warming that began in the early 20th century (1925 - 1944) is consistent with natural variability of the climate system (including a generalized lack of significant volcanic activity, which has a cooling effect), solar forcing, and initial forcing from greenhouse gases.

In September 2014, Koonin wrote an editorial where he acknowledged human - caused climate change was happening but wrote that the «impact today of human activity appears to be comparable to the intrinsic, natural variability of the climate system itself.»

«There is a difference between short term natural variability of the climate and longer term climate change,» Sez who?

The researchers, from the University of Reading and University of Iowa, found that large parts of the projected changes in AR frequency and intensity would be down to thermodynamic changes in the atmosphere, rather than the natural variability of the climate, suggesting that it is a response to anthropogenic climate change.

Previous studies have shown that an essential part of the natural variability of our climate during glacial times is the repeated occurrence of abrupt climate transitions, known as Dansgaard - Oeschger events.

These variations originate primarily from fluctuations in carbon uptake by land ecosystems driven by the natural variability of the climate system, rather than by oceans or from changes in the levels of human - made carbon emissions.

So our interest is to understand — first the natural variability of climate — and then take it from there.

Uncertainties in our understanding of climate processes, the natural variability of the climate, and limitations of the GCMs mean that their results are not definite predictions of climate.»

So our interest is to understand — first the natural variability of climate — and then take it from there.

Finally, the components within each stream are identified as belonging to Phase I or II research, and the limits placed by the natural variability of the climate system on what can be learned from low - level Phase II field - testing are roughly assessed.

Rising temperatures could be due to the natural variability of the climate and global warming from increasing greenhouse gas emissions, Dave Britton, Met Office forecaster, told Reuters.

Uncertainties in our understanding of climate processes, the natural variability of the climate, and limitations of the GCMs mean that their results are not definite predictions of future climate.

«El Niño and La Niña are major drivers of the natural variability of our climate.

Even assuming the models are a perfect characterisation of the forced response and natural variability of the climate system (in statistical terms), his calculation will (with high probability) find that the obs are not consistent with the mean.

Some scientists believe in man - made global warming theory, but think that the natural variability of climate has been seriously underestimated, i.e., man - made global warming is not as urgent a crisis as is commonly believed.

During the last 10,000 years, there is emerging evidence of significant rapid regional temperature changes, which are part of the natural variability of climate.

The natural variability of the climate can cause considerable fluctuation in global temperatures year on year, in spite of an overall upward trajectory.

This implies that natural variability of the climate is the prime cause of increasing CO2, not the emissions of CO2 from the use of fossil fuels.

Modes or patterns of climate variability - Natural variability of the climate system, in particular on seasonal and longer time scales, predominantly occurs with preferred spatial patterns and time scales, through the dynamical characteristics of the atmospheric circulation and through interactions with the land and ocean surfaces.

The report acknowledged that it was not fully understood, but said such pauses had occurred in the past and the natural variability of climate was a likely explanation.
