Sentences with phrase «climate archives»
"Climate archives" refers to various sources of information that scientists use to understand the Earth's climate patterns and changes over time. These archives can include things like ice cores, tree rings, sediment layers, and historical documents. They provide valuable data that helps researchers study past climate conditions and make predictions for the future. Full definition

The result: measured and climate archive data closely correspond to model runs for periods of years.
To bridge the knowledge gap, shallow - water corals have emerged as crucial climate archives.
In 1989 she went to the Galápagos hoping to use the natural climate archives stored in corals to develop a long - term record of El Niño, but found that none of the large, old corals others reported had survived the intense warming of the 1982 - 83 El Niño.
Using different calibration and filtering processes, the two researchers succeeded in combining a wide variety of available data from temperature measurements and climate archives in such a way that they were able to compare the reconstructed sea surface temperature variations at different locations around the globe on different time scales over a period of 7,000 years.
In 1989, she went to the Galápagos hoping to use the natural climate archives stored in corals to develop a long - term record of El Niño, but found that none of the large, old corals others reported had survived the intense warming of the 1982 - 1983 El Niño.
«the 1,470 - year climate response in the simulation is restricted to glacial climate and can not be excited for substantially different (such as Holocene) boundary conditions... Thus, our mechanism for the glacial, 1,470 - year climate cycle is also consistent with the lack of a clear and pronounced 1,470 - year cycle in Holocene climate archives.»
Such climate archives generally refer to spatially limited areas and differ in their temporal resolution.
In order to reconstruct climate history, it is necessary to study natural climate archives since, in terms of Earth's history, humankind has only very recently begun measuring the planet.
The consequence: either the analysed climate archives supply inaccurate temperature signals, or the tested models underestimate the regional climate fluctuations in Earth's recent history.
In the study, scientists from the Potsdam - based Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, and Harvard University show that sea surface temperatures reconstructed from climate archives vary to a much greater extent on long time scales than simulated by climate models.
The results are based on a number of independent climate archives, as well as instrumental records, and hold up whilst applying a wide range of correction methods, which leads Laepple to believe that the problem lies more with the models.
On a millennial time scale, conventional climate models underestimated the variations of sea surface temperatures reconstructed from climate archives by a factor of 50.
To do so, we need reliable climate archives, and to improve our understanding of how they work.»

Using 511 local climate archives from all seven continents, researchers involved in the university's PAGES (Past Global Changes) programme catalogued past temperature patterns based on tree rings, pollen, coral, the dimensions of lakes and oceans, stalagmites, ice cores and historic documents.
«the 1,470 - year climate response in the simulation is restricted to glacial climate and can not be excited for substantially different (such as Holocene) boundary conditions... Thus, our mechanism for the glacial, 1,470 - year climate cycle is also consistent with the lack of a clear and pronounced 1,470 - year cycle in Holocene climate archives.»
Since 2000, there has been a major effort to digitise historical climate data as a part of various projects, for example Computerising the Australian Climate Archives (CLIMARC; Clarkson et al., 2001).
