This article explores the range of methods available to analyse ice and deep-sea sediment cores. It also explores the value of such cores in the context of reconstructing a record of Quaternary climate change, or paleoclimatic reconstruction. Paleoclimatic reconstruction is an extremely important and ...
On the one hand, we marvel at the tremendous scale revealed through their vast calderas and high-piled deposits, and we can intuit their climate-shifting capacity via ice cores, tree rings and microbes that alter their structure in response to climate changes. On the other, there's just so...
“We need to accelerate and intensify efforts to recover Antarctic meteorites. The loss of Antarctic meteorites is much like the loss of data that scientists glean from ice cores collected from vanishing glaciers – once

Climate, 2019) has cited this concentration as the best-case scenario for the year 2100; in June 2019, the level was 415 ppm. Back then, the Antarctic ice shelves now floating on the ocean had most likely completely collapsed. “Based on the sediment deposits we can tell, for example, ...
How long ago did the last Ice Age end?Ice agesAn ice age is an extensive period of time characterized by the cooling of global temperatures, and the formation of large glacial ice covering much of the surface of the earth. There have been five major ice age events in the Earth's ...
“Our international team worked together to both create this unique record and explain its significance through mathematical modeling, so we can reconstruct changes in the past when the climate conditions were different. The hope is to gain insight into how our blue planet might operate in the ...
This type of rapid glacial flow already occurred nearby, when the Larsen B ice shelf crumbled in 2002. For an ecologist like Moore Powell, there are also myriad questions to answer about how ecosystems will respond to a changing climate. If the pace is slow enough, plants and animals can ...
Greenhouse gases and ice sheet change We know that Antarctica has changed in the past because of the information held in the deep ice cores that researchers have taken there. Since the late 1960s, Russian and French scientists have extracted a column of ice greater than 4 kilometers in length...
I’ve tested a lot of ice cores, and have yet to find one that rejects the Null. Brian Angliss January 2, 2016 at 8:06 am CO2isLife –“I provided you the link to all the data sets, just show me one that I can test that make the scientific case for AGW, just one. Show me...
