Sentences with phrase «natural climate archives»

The lack of widespread instrumental climate records introduces the need for the use of natural climate archives from «proxy» data such as tree - rings, corals, speleothems and ice cores, as well as documentary evidence to reconstruct climate in past centuries (see Jones et al. 2009 for a review).

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.

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.

Not exact matches

«One of our biggest challenges was to make it possible to compare various measured data and climate archives from a wide variety of regions and filter out the natural noise that can greatly distort the signal of climate archives.»

This approach is a natural fit for climate science: a single run of a high - resolution climate model can produce a petabyte of data, and the archive of climate data maintained by the UK Met Office, the national weather service, now holds about 45 petabytes of information — and adds 0.085 petabytes a day.

Another way to study the link is through paleoclimate observations where past climate is reconstructed through natural archives.

He uses tree - ring records in combination with other natural archives and documentary sources to reconstruct the histories of fire, insect outbreaks, human land uses, and climate.

There is more evidence of abrupt and violent change, most of it culled from ice cores, lake sediments, tree rings and other natural archives of climate.

However, both the driving force and the climate reconstructions over the pre-industrial era are based on the analysis of the natural archives of climate sensitive quantities, such as the growth of trees and seashells, and the changes of chemical, biological, and isotopic compositions in lake sediments and ice core samples.

According to his archived profile at the Austrian Academy of Sciences website, Patzelt's research focus is in «Glacier and climate history research,» «Mass movements (landslides, fluvial Sedimentationsereignisse),» «Historic natural and cultural landscape development in alpine areas,» and «Participation in projects of Antarctic Research.»

To gain a longer view, Dr Jones and her colleagues used a compilation of records from natural archives such as ice cores from the Antarctic ice sheet, which show how the region's climate has changed over the last 200 years.

Information about climate changes has been obtained mainly from variations in the concentration of stable isotopes in the natural archives.

Estimates of surface temperature changes further back in time must therefore make use of the few long available instrumental records or historical documents and natural archives or «climate proxy» indicators, such as tree rings, corals, ice cores and lake sediments, and historical documents to reconstruct patterns of past surface temperature change.
