We are pleased to announce that the third workshop of the PAGES Australasia2k Working Group will be held in Melbourne on 26-27 June 2014. This will be a joint meeting with the Australian Climate Change Science Program (ACCSP) project “Variability of Australian climate over the last 1000 years in coupled model simulations and proxy data”….
Continue ReadingA small workshop was held on the 28-29th January 2014 in Auckland to discuss the Southern Hemisphere Westerly Winds and how they might have changed over time. See the SHAPE webpage and scroll down to find a link to the summary pdf. from this recent workshop. Please get in touch with anyone listed if you…
Continue ReadingBy Ignacio A. Jara and Helen Bostock Terrestrial dust is important to the climate system not only because it may alter the solar radiative balance of the earth, but also because it supplies the oceans with key iron (Fe), a limiting micronutrient for phytoplankton productivity in the Southern Ocean. The “Iron Hypothesis” was first proposed…
Continue ReadingBy Helen Bostock Over the last decade the main theory to explain the changes in the atmospheric concentration of CO2 between glacials and interglacials, has primarily focussed on changes in the circulation of the Southern Ocean controlling the release of CO2 from the deep-ocean reservoir. However, there is still considerable debate about the path and…
Continue ReadingMemberships are well and truly due and you can pay these easily online. It is easy, so please get yourself signed up and encourage your colleagues, students and friends. This is a great time to sign new people up, as anyone that joins AQUA now will automatically have their membership extended right through to 28 February 2015. Members…
Continue ReadingWritten by Ignacio Jara, Victoria University Wellington. While the abrupt climate transitions of the glacial termination and the establishment of the present-day modes of climate variation during the Holocene seems to be well characterized in proxy records around the Southern Hemisphere, there is still sparse evidence about the impact of those changes on the migration,…
Continue ReadingWritten by Ignacio Jara, Victoria University Wellington Although the long-term changes in solar insolation between Northern Hemisphere (NH) and the Southern Hemisphere (SH) are in anti-phase, marine and ice core records from both hemispheres show highly synchronous glacial/interglacial cycles over the last 800 kyr. This disparity between the insolation and the paleo-records is probably the…
Continue ReadingThe first SHAPE workshop was held at GNS Science on the 16-17th September 2013. A summary of the talks and discussion at the workshop can be found on the SHAPE project page. Lots of ideas were discussed and it was clear that there is still momentum continuing on from the Aus-INTIMATE project. There is a long…
Continue ReadingAustralia provides an outstanding case study to resolve the relationship between Late Quaternary environmental drivers such as climate variability, vegetation changes, wildfires, faunal extinctions and human activities. The interval between 50,000-40,000 years BP is critical for understanding the interplay of some of these factors and how they transformed the Australian landscape. During this period, humans…
