The IGBP-PAGES WCRP-CLIVAR Intersection activity Overall goal of CLIVAR/PAGES intersection: To improve the understanding of decadal to centennial climate variability www.clivar.org/organization/pages/ www.pages-igbp.org www.clivar.org PAGES Areas of Interest CLIVAR Areas of Interest PAGES / CLIVAR in the past: History - Developed in the early 90’s - to improve understanding of decadal to century scale climate variability - high-resolution paleoclimatic data to improve the predictability of change (corals, tree-rings, varved sediments and ice cores, ...) Topics • dynamics of low-latitude climate change • global ocean thermohaline variability • regional-to-global scale hydrologic variability • dynamics of abrupt climatic change • model evaluation and improvement • climate change detection PAGES / CLIVAR- the past MEETINGS: •Venice meeting 1999: Linking modeling-data community •Il Ciocco, Italy, 2001: Abrupt Climate Change •Hadley Cell workshop 2002: Merging of P/C scientists •Drought workshop, US 2003: International networking •ESF, Spain, 2003: Linking modeling-data community •PMIP Meetings •The Paleoclimate Intercomparison Project (PMIP) •P/C networking within other programs (EPICA/IMAGES) •P/C addressed some IPCC questions - Paleo chapter in next report! PAGES/CLIVAR present and future Reconstitution and revision: • C/P-intersection working group meeting; Victoria, Canada, November 2004 Developed new vision to reflect more specific issues, based on paleo-reconstruction, instrumental data analysis, and modeling, Co-chairs: Gavin Schmidt (CLIVAR) Eystein Jansen (PAGES) PAGES / CLIVAR: new vision Key scientific issues • Climate variability over the last few millennia • Abrupt climate change - extreme events • Hydrologic, biospheric, land-surface interactions: Constrain/evaluate models; Expansion of the PMIP activities • Tropical-extratropical links including ocean and atmospheric teleconnections • Overarching and Cross-cutting Implementation issues: Outreach - workshops - link model/data communities Climate Variability - Past Millennia Assessment and improvement of models ... Jones and Mann, 2004 Climate Variability - Past Millennia Europe and Northern Hemisphere: 500-year temperature variability ... and reconstructions. Luterbacher et al. 2004 Climate Variability - Past Millennia Detect key regions for T / P reconstructions. Merge the regional information for a global view! Some activity already started in Europe and SAmerica, Antarctica in prep. Climate Variability - Past Millennia Funded by EPRI (Electric Power Research Institute), PAGES and CLIVAR Climate Variability - Past Millennia Sub-themes -Forcing and modeling -Methods of multiproxy reconstructions -Model/data comparison -Spatial patterns of past climate change Abrupt Climate Change: Is abrupt change likely under anthropogenic influence? 30 25 Age, ky before present 20 15 10 -34 -36 18 d O Greenland temperature -38 -40 -42 -44 “8.2 ky event” Grootes et al. 1993 Clarke et al. 2003 5 0 Abrupt Climate Change: Temperature °C Precipitation mm/day 18O precip ‰ 18O seawater ‰ Modeled response to meltwater influx into the N.

ENSO Other issues of joint interest between PAGES and CLIVAR include the NAO, PDO, Monsoons, IOD with regard to past strength and activity.
